D455 Professional Nursing Role Transition - Set 1 - Part 2

Correct Answer: Administer prescribed regular insulin dose

Option a is correct because the priority in early diabetic ketoacidosis is administering regular insulin to correct hyperglycemia and halt ketone production, as the underlying cause is an absolute insulin deficit that fluids alone cannot address. Option b is incorrect because drinking electrolyte fluids alone does not address the fundamental insulin deficit driving the hyperglycemia and ketone production, and without insulin administration, the metabolic crisis will continue to worsen progressively. Option c is incorrect because measuring urine output over twenty-four hours is a monitoring activity that dangerously delays the urgent need for insulin administration, allowing the metabolic acidosis to progress toward potentially life-threatening complications. Option d is incorrect because eating a meal will further increase the already dangerously elevated blood glucose level without addressing the insulin deficit, and nausea associated with DKA typically worsens with food intake as aci

Correct Answer: The frequency of foot inspections stated

Option d is correct because clients with diabetes should perform daily foot inspections rather than monthly, as peripheral neuropathy can mask injuries and infections that progress rapidly without early detection and intervention. Option a is incorrect because assessing for sores and skin changes is an appropriate type of foot assessment for a diabetic client, and this component of the client's statement demonstrates correct understanding of what to look for during inspections. Option b is incorrect because the feet are the correct anatomical location for self-assessment in diabetic clients, as peripheral neuropathy and decreased circulation most commonly affect the lower extremities and feet first. Option c is incorrect because the client's described technique of visually checking for sores and skin changes represents an appropriate method for diabetic foot inspection, and the concern lies with how often this assessment is being performed.

Correct Answer: Ophthalmologist examination annually

Option b is correct because annual ophthalmologist examinations are recommended for clients with diabetes to screen for diabetic retinopathy, a leading cause of blindness that can be detected and treated early through routine comprehensive eye examinations. Option a is incorrect because waiting five years between eye examinations is too infrequent for diabetic clients, as retinopathy can develop and progress significantly during that interval, potentially causing irreversible vision loss without timely detection. Option c is incorrect because diabetic retinopathy often progresses without noticeable symptoms until significant vision damage has already occurred, making symptom-based screening dangerously inadequate for early detection and intervention efforts. Option d is incorrect because diabetic retinopathy screening must be ongoing throughout the client's lifetime rather than a one-time referral, as the risk of retinal complications continues and potentially increases with the d

Correct Answer: Intravenous hydrocortisone

Option c is correct because intravenous hydrocortisone replaces the critically deficient cortisol in adrenal crisis, helping normalize the dangerously low sodium and glucose levels while addressing the hyperkalemia caused by inadequate aldosterone production. Option a is incorrect because oral fludrocortisone cannot be reliably absorbed in a dehydrated and confused client in acute adrenal crisis, and the immediate priority is intravenous cortisol replacement to rapidly stabilize the life-threatening electrolyte imbalances. Option b is incorrect because the low glucose of fifty-four indicates hypoglycemia caused by cortisol deficiency rather than hyperglycemia, and administering insulin would dangerously worsen the already critically low blood glucose level in this client. Option d is incorrect because while epinephrine addresses cardiovascular collapse, the underlying pathology in adrenal crisis is cortisol and aldosterone deficiency, and treatment must target the hormone replacement r

Correct Answer: Initiate seizure precautions immediately

Option a is correct because severe hyponatremia below one hundred twenty significantly increases seizure risk due to cerebral edema, and implementing seizure precautions protects the client from injury while other treatments are being initiated to correct sodium levels. Option b is incorrect because while fluid restriction is an important component of SIADH management, it does not address the immediate safety threat of potential seizures from severe hyponatremia and should be implemented after protective measures are established. Option c is incorrect because although hypertonic saline may be prescribed to correct dangerously low sodium levels, the nurse's first priority is ensuring client safety through seizure precautions before initiating treatments that require careful monitoring and titration. Option d is incorrect because obtaining a neurology consultation, while potentially valuable for ongoing management, introduces delays in implementing immediate safety measures for a cl

Correct Answer: Weigh the client and report the result

Option d is correct because weighing a client and reporting the result is a data collection task appropriate for unlicensed assistive personnel, as it does not require clinical interpretation or nursing judgment that must be performed by the registered nurse. Option a is incorrect because evaluating fatigue severity requires clinical nursing judgment to interpret the subjective findings in the context of Cushing syndrome pathophysiology, making this an assessment function that cannot be delegated to unlicensed personnel. Option b is incorrect because assessing muscle weakness patterns requires the registered nurse to apply clinical knowledge of cortisol's catabolic effects on muscle tissue and interpret findings within the broader clinical picture of Cushing syndrome management. Option c is incorrect because interpreting daily weight trends requires the nurse to analyze data in the context of fluid retention, cortisol excess, and treatment effectiveness, which constitutes clinical

Correct Answer: Note and report food and fluid intake

Option a is correct because recording food and fluid intake during meals is an objective data collection task within the unlicensed assistive personnel's scope, requiring observation and documentation rather than clinical interpretation or nursing judgment. Option b is incorrect because assessing skin changes requires the registered nurse to differentiate between expected findings related to cortisol excess and new complications, involving clinical judgment that exceeds the training and scope of unlicensed personnel. Option c is incorrect because evaluating sleep disturbance patterns requires nursing knowledge to determine whether disruptions relate to cortisol hypersecretion, medication side effects, or other clinical factors that demand professional interpretation and assessment skills. Option d is incorrect because monitoring for hyperglycemia signs requires the nurse to recognize subtle clinical manifestations of glucose dysregulation associated with excess cortisol production

Correct Answer: Report any mention of pain to the nurse

Option c is correct because unlicensed assistive personnel should report any client mention of pain or discomfort to the registered nurse, who then performs the complete pain assessment and determines appropriate interventions requiring clinical judgment. Option a is incorrect because unlicensed assistive personnel are not trained or authorized to independently document pain assessments or determine pain management interventions, as these activities require the clinical judgment and licensure of a registered nurse. Option b is incorrect because all client reports of pain must be communicated to the registered nurse regardless of perceived severity, as unlicensed personnel lack the clinical training to determine which pain reports warrant nursing attention and intervention. Option d is incorrect because performing a comprehensive pain assessment including intensity, quality, location, and aggravating factors requires clinical nursing skills and interpretation that fall outside the educa

Correct Answer: Excess cortisol promotes insulin resistance

Option b is correct because excess cortisol in Cushing syndrome promotes gluconeogenesis and opposes insulin action at the cellular level, leading to persistent hyperglycemia that requires careful glucose monitoring throughout the client's hospitalization. Option a is incorrect because cortisol actually increases hepatic glucose production through stimulation of gluconeogenesis rather than decreasing it, which is one of the primary mechanisms contributing to the hyperglycemia commonly seen in Cushing syndrome. Option c is incorrect because excess cortisol impairs peripheral glucose uptake by opposing insulin's ability to facilitate cellular glucose transport, which is the opposite of enhancing uptake and contributes directly to elevated blood glucose levels. Option d is incorrect because while the pancreas may initially increase insulin secretion to compensate for cortisol-induced resistance, the fundamental problem is tissue resistance to insulin's effects rather than i

Correct Answer: The client mentioned dizziness when standing

Option d is correct because dizziness upon standing in a client with Cushing syndrome could indicate orthostatic hypotension, fluid imbalance, or electrolyte disturbance requiring immediate nursing assessment to prevent falls and identify deteriorating clinical status. Option a is incorrect because completing lunch is a routine dietary observation that can be documented during regular intake and output reporting and does not represent a change in clinical condition requiring immediate registered nurse notification. Option b is incorrect because requesting a blanket change is a comfort measure that the unlicensed assistive personnel can address independently as part of routine client care without requiring immediate communication to the registered nurse. Option c is incorrect because assistance with television operation is a routine comfort request that falls within standard UAP responsibilities and does not indicate any clinical change warranting immediate nursing assessment or interve

Correct Answer: Serum sodium level

Option c is correct because the excessive dilute urine output following craniotomy suggests diabetes insipidus from disrupted antidiuretic hormone production, and the massive water loss leads to hypernatremia that can cause dangerous neurological complications if undetected. Option a is incorrect because while electrolyte monitoring is important in fluid imbalances, serum sodium is the priority laboratory value in suspected diabetes insipidus because hypernatremia directly causes the most immediate and life-threatening neurological consequences. Option b is incorrect because a urine culture tests for bacterial infection and is not relevant to the massive dilute urine output caused by antidiuretic hormone deficiency, which is the endocrine mechanism driving this postoperative complication. Option d is incorrect because hemoglobin and hematocrit values, while potentially affected by severe dehydration through hemoconcentration, do not directly assess the critical hypernatremia risk that

Correct Answer: High urine output with low specific gravity

Option a is correct because diabetes insipidus produces massive volumes of very dilute urine with low specific gravity due to the kidneys' inability to concentrate urine without adequate antidiuretic hormone, combined with extreme compensatory thirst. Option b is incorrect because low urine output with elevated creatinine suggests renal impairment or acute kidney injury rather than diabetes insipidus, which characteristically presents with the opposite pattern of excessively high urine volumes. Option c is incorrect because dark concentrated urine with edema suggests fluid retention and adequate or excessive antidiuretic hormone activity, which is the opposite pathophysiology of diabetes insipidus where urine cannot be concentrated. Option d is incorrect because decreased thirst with weight gain suggests fluid retention consistent with syndrome of inappropriate antidiuretic hormone secretion, which is the physiological opposite of diabetes insipidus and its massive fluid losses.

Correct Answer: The medication is producing its expected effect

Option b is correct because desmopressin is a synthetic antidiuretic hormone replacement that reduces excessive urine output by enabling the kidneys to reabsorb water, and decreased urine volume to a normal range indicates successful therapeutic response. Option a is incorrect because the decreased urine output from six hundred to seventy-five milliliters per hour represents normalization toward expected renal function rather than renal failure, which would present with additional findings such as elevated creatinine and fluid retention. Option c is incorrect because the reduction in urine output to approximately seventy-five milliliters per hour falls within the normal expected range for adequate kidney function, indicating appropriate dosing rather than overmedication requiring immediate adjustment. Option d is incorrect because the decreased urine output reflects improved water reabsorption from effective desmopressin therapy rather than worsening dehydration, which would present wi

Correct Answer: DI causes dilute urine while SIADH causes retention

Option d is correct because diabetes insipidus produces large volumes of dilute urine from insufficient antidiuretic hormone, while SIADH causes water retention and concentrated urine from excessive antidiuretic hormone, creating opposite fluid balance presentations. Option a is incorrect because only SIADH produces concentrated urine due to excessive water reabsorption, while diabetes insipidus characteristically produces very dilute urine with abnormally low specific gravity from the inability to concentrate urine properly. Option b is incorrect because the two conditions produce opposite sodium disturbances: diabetes insipidus causes hypernatremia through excessive water loss while SIADH causes dilutional hyponatremia through excessive water retention in the body. Option c is incorrect because SIADH causes decreased urine output with water retention and fluid overload, which is the physiological opposite of diabetes insipidus where massive urine volumes are produced due to inadequat

Correct Answer: Seizures from severe hypernatremia

Option a is correct because severe hypernatremia causes cellular dehydration in the brain leading to neuronal shrinkage, which can trigger seizures, permanent brain damage, and death if sodium levels are not carefully corrected with appropriate fluid replacement. Option b is incorrect because while extreme electrolyte imbalances can affect cardiac function, the most immediate and dangerous complication of severe hypernatremia in diabetes insipidus is neurological deterioration rather than primary cardiac arrest from sodium elevation alone. Option c is incorrect because pulmonary edema results from fluid overload rather than the severe dehydration seen in diabetes insipidus, and the clinical presentation of this client reflects volume depletion rather than excessive fluid accumulation in tissues. Option d is incorrect because while dehydration can impair renal function, the nurse's most immediate concern with a sodium of one hundred sixty-two and neurological symptoms is preventing

Correct Answer: Intravenous levothyroxine sodium

Option b is correct because myxedema coma severely impairs gastrointestinal absorption, making oral and sublingual routes unreliable, and intravenous levothyroxine sodium provides the rapid onset of action needed in this life-threatening endocrine emergency. Option a is incorrect because oral levothyroxine cannot be safely administered to an unresponsive client and would not be reliably absorbed due to the profoundly decreased gastrointestinal motility and absorption that characterize severe myxedema coma. Option c is incorrect because sublingual administration requires a conscious client who can hold the tablet under the tongue, and even if placed sublingually, the severely decreased peripheral circulation in myxedema coma would impair mucosal absorption significantly. Option d is incorrect because intramuscular thyroid extract is not the standard of care for myxedema coma, as the decreased peripheral perfusion and subcutaneous edema in severe hypothyroidism make intramuscular absorpt

Correct Answer: Thyroid hormone deficiency slows metabolism

Option c is correct because thyroid hormones regulate basal metabolic rate throughout the body, and their severe deficiency in myxedema coma profoundly decreases cellular metabolism, causing bradycardia, hypothermia, and respiratory depression systemically. Option a is incorrect because while adrenal insufficiency can coexist with hypothyroidism, the primary cause of the profoundly decreased vital signs in myxedema coma is the absence of thyroid hormones that regulate metabolic rate across all organ systems. Option b is incorrect because although fluid retention occurs in hypothyroidism due to decreased renal free water clearance, the primary mechanism driving the critically low vital signs is severely depressed cellular metabolism from thyroid hormone deficiency. Option d is incorrect because cerebral edema causing brainstem depression is not the primary mechanism in myxedema coma, as the decreased level of consciousness results from profoundly slowed cerebral metabolism due to system

Correct Answer: Rapid thyroid replacement may trigger adrenal crisis

Option a is correct because administering thyroid hormones rapidly increases metabolic demands including cortisol requirements, and if underlying adrenal insufficiency coexists, the increased metabolic rate can precipitate a life-threatening adrenal crisis without corticosteroid coverage. Option b is incorrect because corticosteroids do not enhance the absorption or bioavailability of intravenous levothyroxine, as the thyroid medication is administered directly into the bloodstream and does not require enhancement of its pharmacokinetic properties. Option c is incorrect because corticosteroids are not administered to prevent allergic reactions to levothyroxine in myxedema coma treatment, as anaphylaxis to intravenous thyroid hormone is not a recognized clinical concern driving this concurrent medication administration. Option d is incorrect because cortisol does not directly stimulate thyroid gland tissue recovery or regeneration, and the rationale for concurrent corticosteroid adminis

Correct Answer: Apply passive rewarming with blankets

Option d is correct because passive rewarming with blankets is the safest approach for myxedema coma because aggressive external rewarming can cause peripheral vasodilation, leading to cardiovascular collapse in a client whose heart cannot increase output adequately. Option a is incorrect because aggressive application of heated blankets causes rapid peripheral vasodilation that the severely bradycardic heart in myxedema coma cannot compensate for, potentially triggering dangerous hypotension and cardiovascular collapse. Option b is incorrect because rapid warm intravenous fluid boluses can overwhelm the already compromised cardiovascular system in myxedema coma, as the severely depressed cardiac function cannot adequately handle sudden increases in circulating volume. Option c is incorrect because forced hot air warming devices provide aggressive active rewarming that carries the same peripheral vasodilation risks as heated blankets, potentially causing fatal circulatory collapse in t

Correct Answer: Hypothermia with bradycardia and hypoventilation

Option b is correct because myxedema coma classically presents with hypothermia, bradycardia, and hypoventilation reflecting the profoundly decreased metabolic rate caused by severe thyroid hormone deficiency affecting all organ systems simultaneously. Option a is incorrect because high fever with tachycardia and tremors describes thyroid storm, which is the opposite endocrine emergency caused by excessive thyroid hormone production and a dangerously hypermetabolic state rather than thyroid deficiency. Option c is incorrect because myxedema coma characteristically produces hypothermia and hypotension rather than normal temperature with elevated blood pressure, as the severely depressed metabolism affects thermoregulation and cardiovascular function profoundly. Option d is incorrect because hyperthermia with rapid deep respirations suggests a hypermetabolic state such as thyroid storm, sepsis, or metabolic acidosis, which are physiologically opposite to the severely depressed metabolic
