D455 Professional Nursing Role Transition - Set 2 - Part 1

Correct Answer: Cushing causes high potassium and low glucose

Option c is correct because heart failure clients require fluid restriction to prevent volume overload, and an unrestricted full water pitcher at the bedside directly undermines this critical intervention and could significantly worsen pulmonary congestion. Option a is incorrect because a bedside commode is actually appropriate for heart failure clients as it significantly reduces cardiac workload compared to walking to the bathroom and helps conserve myocardial oxygen demand during toileting. Option b is incorrect because a low-sodium diet tray is a therapeutic intervention for heart failure clients since sodium restriction reduces fluid retention and decreases the cardiac workload associated with excess circulating volume. Option d is incorrect because low-flow supplemental oxygen via nasal cannula is an appropriate supportive intervention for heart failure clients experiencing dyspnea, helping to maintain adequate tissue oxygenation without excessive oxygen delivery.

Correct Answer: Elevate the head of bed

Option a is correct because elevating the head of bed reduces venous return to the heart, decreases pulmonary congestion, and improves diaphragmatic excursion, providing the most immediate relief for orthopnea associated with decompensated heart failure. Option b is incorrect because the prone position increases pressure on the chest and abdomen, further restricting diaphragmatic movement and worsening respiratory effort in a client already experiencing heart failure related dyspnea. Option c is incorrect because a lateral recumbent position does not significantly reduce venous return or pulmonary congestion and fails to address the primary mechanism causing dyspnea in decompensated heart failure exacerbation. Option d is incorrect because lowering the foot of the bed does not address the primary problem of increased venous return and pulmonary congestion, and may paradoxically increase blood flow returning to the already overwhelmed heart.

Correct Answer: Whole almonds and air-popped popcorn

Option d is correct because natural unsalted whole almonds provide heart-healthy fats and plain air-popped popcorn is low in sodium and high in fiber, both aligning with the sodium-restricted and weight-conscious dietary needs of heart failure clients. Option a is incorrect because cheddar cheese is high in both sodium and saturated fat while canned fruit in heavy syrup adds unnecessary sugar, neither of which supports the dietary restrictions required for heart failure management. Option b is incorrect because salted chips are extremely high in sodium content which promotes fluid retention and worsens heart failure, directly contradicting the sodium restriction essential for managing this chronic cardiac condition effectively. Option c is incorrect because canned vegetables typically contain very high sodium levels from the preservation process, making them inappropriate for heart failure clients who require strict sodium restriction to prevent fluid volume overload.

Correct Answer: Metformin and propranolol

Option b is correct because metformin increases lactic acidosis risk when tissue perfusion is compromised in acute heart failure, and propranolol reduces cardiac contractility which can further worsen acute decompensation and hemodynamic instability. Option a is incorrect because lisinopril and amlodipine are not the priority medications to withhold during acute decompensated heart failure, as ACE inhibitors and calcium channel blockers may still have roles depending on the clinical context. Option c is incorrect because furosemide is actually a cornerstone treatment for acute heart failure as it promotes diuresis to reduce volume overload, and potassium supplementation may be needed to replace diuretic-related losses. Option d is incorrect because digoxin can improve cardiac contractility in heart failure and hydrochlorothiazide supports diuresis, making this combination potentially therapeutic rather than harmful during acute decompensated heart failure episodes.

Correct Answer: Excessive oxygen may suppress respiratory drive

Option a is correct because clients with chronic COPD may rely on hypoxic drive for respiratory stimulation, and delivering excessive oxygen at five liters per minute can dangerously suppress this drive, potentially causing respiratory failure and carbon dioxide retention. Option b is incorrect because a nonrebreather mask is reserved for higher oxygen concentrations in emergency situations and five liters per minute can be appropriately delivered through a simple face mask when clinically indicated for most patients. Option c is incorrect because while humidified oxygen provides comfort and prevents mucosal drying at higher flow rates, the primary concern with this client is the excessive oxygen delivery rate rather than the absence of humidification equipment. Option d is incorrect because simple face masks can effectively deliver oxygen at five liters per minute, typically providing approximately forty percent oxygen concentration, so the delivery device itself is not the clinical c

Correct Answer: Sublingual nitroglycerin

Option d is correct because combining nitroglycerin with phosphodiesterase-5 inhibitors like sildenafil causes severe and potentially fatal hypotension through synergistic vasodilation, making nitrate administration absolutely contraindicated within the therapeutic window of sildenafil use. Option a is incorrect because aspirin is a standard treatment for acute coronary syndrome that inhibits platelet aggregation and has no dangerous interaction with phosphodiesterase-5 inhibitors, making it safe to administer in this clinical scenario. Option b is incorrect because morphine sulfate can be administered for pain management in acute coronary syndrome and does not have the same dangerous synergistic vasodilatory interaction with sildenafil that nitrate medications produce. Option c is incorrect because intravenous heparin is an anticoagulant used in acute coronary syndrome management and does not interact with phosphodiesterase-5 inhibitors to cause the severe hypotensive response associa

Correct Answer: Flushing is a common expected effect

Option b is correct because skin flushing is a well-documented and common side effect of phosphodiesterase-5 inhibitors like tadalafil, resulting from vasodilation, and does not represent an allergic reaction requiring emergency intervention or medication discontinuation. Option a is incorrect because facial flushing without accompanying symptoms like chest pain, severe hypotension, or difficulty breathing does not constitute a medical emergency and directing the client to the emergency department would be unnecessary and inappropriate. Option c is incorrect because flushing alone is an expected pharmacological effect of tadalafil rather than an adverse reaction, and permanently discontinuing the medication based solely on this common side effect is not clinically warranted. Option d is incorrect because the flushing is caused by vasodilation from the medication's mechanism of action rather than a histamine-mediated allergic response, so antihistamine administration would not addr

Correct Answer: Check adhesion of the pacemaker pads

Option c is correct because poor pad contact is the most common and easily correctable cause of transcutaneous pacemaker failure to capture, and verifying proper adhesion should always be the first troubleshooting step before escalating to other interventions. Option a is incorrect because battery replacement is a secondary consideration after confirming proper pad adhesion, as most transcutaneous pacemaker failures result from contact issues rather than power supply problems with the external generator unit. Option b is incorrect because while chest hair can interfere with pad contact, shaving should be considered after first checking whether the current pads have adequate adhesion, as repositioning or replacing pads may resolve the capture failure immediately. Option d is incorrect because the nurse should first attempt basic troubleshooting by checking pad adhesion before notifying the healthcare provider, as this simple intervention frequently resolves intermittent capture failure

Correct Answer: Third-degree heart block developed

Option a is correct because complete atrioventricular dissociation with a slow ventricular rate indicates third-degree heart block, a life-threatening complication following dronedarone administration that causes hemodynamic instability and may require emergency pacemaker placement. Option b is incorrect because atrial fibrillation shows irregularly irregular ventricular response rather than complete atrioventricular dissociation, and the described rhythm pattern with a slow ventricular rate is inconsistent with a return of atrial fibrillation. Option c is incorrect because normal sinus rhythm demonstrates coordinated atrial and ventricular activity with a regular rate, which is fundamentally different from the described pattern of complete dissociation between atrial and ventricular electrical activity. Option d is incorrect because dronedarone is intended to maintain normal sinus rhythm after cardioversion, and the development of complete heart block with hemodynamic compromise repre

Correct Answer: Oatmeal with fresh berries

Option d is correct because oatmeal contains soluble fiber that actively reduces cholesterol levels and fresh berries provide antioxidants without added sodium or saturated fat, making this combination ideal for slowing coronary artery disease progression. Option a is incorrect because buttered white toast adds saturated fat and refined carbohydrates to the meal, and while eggs can be part of a heart-healthy diet, the butter directly contributes to increased cholesterol and atherosclerotic plaque formation. Option b is incorrect because while yogurt provides protein, many commercial granolas and added honey contain excessive sugar and calories that can contribute to weight gain and metabolic dysfunction, undermining coronary artery disease management goals. Option c is incorrect because bacon is high in sodium and saturated fat while cheese adds additional saturated fat and sodium, creating a meal that directly accelerates atherosclerotic plaque formation and worsens coronary artery di

Correct Answer: Raise head of bed to thirty degrees

Option b is correct because elevating the head of bed to thirty degrees with the head and neck in neutral alignment promotes venous drainage from the brain, reduces intracranial pressure, and is the standard positioning for clients presenting with acute stroke symptoms. Option a is incorrect because placing the client flat can increase intracranial pressure by impeding venous drainage from the brain, potentially worsening cerebral edema and neurological damage during the critical acute phase of stroke management. Option c is incorrect because the right lateral recumbent position does not specifically promote cerebral venous drainage and may compromise assessment of the client's neurological status, which requires ongoing monitoring during the acute stroke evaluation. Option d is incorrect because elevating the legs above the heart increases venous return and can raise intracranial pressure, directly opposing the therapeutic goal of reducing cerebral pressure during an acute stroke

Correct Answer: Use a pictorial communication board

Option c is correct because left cerebral hemisphere damage causes expressive aphasia affecting verbal communication, and a pictorial communication board provides an alternative method for the client to express needs and participate in care decisions effectively. Option a is incorrect because the bedside commode should be placed on the left or unaffected side of the client since right-sided hemiplegia from left brain injury limits the client's ability to safely transfer toward the affected right side. Option b is incorrect because a client with expressive aphasia from left hemisphere damage has difficulty producing speech but may also have receptive language impairment, making verbal-only instructions potentially ineffective without supplemental visual communication aids. Option d is incorrect because the affected right side must be properly supported during repositioning to prevent injury, maintain alignment, and protect paralyzed extremities from dependent edema, contractures, a

Correct Answer: Stop the feeding and assess swallowing

Option a is correct because stroke clients are at extremely high risk for aspiration, and giving any fluids without first confirming intact swallowing function through a bedside swallow assessment could cause aspiration pneumonia, a potentially fatal complication. Option b is incorrect because allowing small sips assumes the swallowing reflex is intact, which has not been verified in this client with facial paralysis and stroke symptoms, creating an unacceptable risk for aspiration and subsequent respiratory complications. Option c is incorrect because replacing water with thickened liquids still requires a confirmed swallowing assessment first, as even modified consistency fluids can be aspirated when the swallowing reflex is impaired following a cerebrovascular accident. Option d is incorrect because the issue is not who is providing the fluids but rather that no swallowing assessment has been performed, and continuing oral intake of any kind without confirming swallow function place

Correct Answer: On the client's left or unaffected side

Option d is correct because placing the commode on the unaffected left side allows the client to lead the transfer with the stronger left extremities, maximizing independence and safety while reducing fall risk during toileting activities. Option a is incorrect because placing the commode at the foot of the bed increases the distance the client must travel and does not allow the client to use the stronger unaffected side for safe pivot transfers during toileting. Option b is incorrect because positioning the commode across the room significantly increases fall risk by requiring the hemiplegic client to ambulate an unnecessary distance, contradicting the principles of energy conservation and safe transfer techniques. Option c is incorrect because placing the commode behind the head of bed creates an awkward and unsafe transfer angle that does not support the hemiplegic client's ability to lead with the stronger unaffected side during the transfer process.

Correct Answer: Maintain blood pressure below target monthly

Option b is correct because maintaining blood pressure below a specific target within a defined timeframe represents a measurable, time-limited, and clinically relevant outcome that directly addresses cardiovascular disease risk reduction and disease progression monitoring. Option a is incorrect because eliminating all dietary fat is neither realistic nor healthy, as the body requires essential fatty acids for cellular function, and the goal should focus on reducing saturated fats while incorporating heart-healthy unsaturated fats. Option c is incorrect because feeling less stressed is a subjective and unmeasurable outcome that lacks specificity and a defined timeframe, making it inappropriate as a clinical outcome in a structured cardiovascular disease management care plan. Option d is incorrect because avoiding all physical activity contradicts evidence-based cardiovascular disease management guidelines that recommend regular moderate exercise such as walking thirty minutes daily to

Correct Answer: This is acceptable for a COPD client

Option c is correct because the normal oxygen saturation target for clients with chronic obstructive pulmonary disease is eighty-eight to ninety-two percent, making ninety-four percent actually acceptable and not requiring immediate intervention or escalation to the healthcare provider. Option a is incorrect because ninety-four percent oxygen saturation is not dangerously low for any client population and actually exceeds the acceptable target range for COPD clients who chronically retain carbon dioxide and rely on hypoxic respiratory drive. Option b is incorrect because targeting saturation above ninety-eight percent in emphysema clients is inappropriate and potentially dangerous, as excessive oxygenation can suppress the hypoxic drive that stimulates breathing in chronic carbon dioxide retainers. Option d is incorrect because administering high-flow oxygen to a COPD client with acceptable saturation levels could suppress the hypoxic respiratory drive, potentially causing respiratory

Correct Answer: Emphasize early ambulation after surgery

Option a is correct because early postoperative ambulation prevents complications including atelectasis, pneumonia, deep vein thrombosis, and deconditioning, making it the most critical teaching point for COPD clients undergoing thoracotomy to optimize recovery outcomes. Option b is incorrect because offering cigarette substitutes like nicotine gum is not appropriate surgical preparation content, and the focus should instead be on smoking cessation benefits for wound healing and improved pulmonary function during recovery. Option c is incorrect because strict bedrest is contraindicated after thoracotomy as immobility increases the risk of atelectasis, pneumonia, venous thromboembolism, and other postoperative complications that are especially dangerous for COPD clients. Option d is incorrect because breathing exercises including incentive spirometer use should be taught and practiced preoperatively so the client can perform them effectively after surgery when pain and anesthesia effect

Correct Answer: Give brief essentials with written materials

Option d is correct because anxiety and dyspnea significantly impair learning capacity, so the nurse should prioritize essential safety information delivered in short simple explanations while providing comprehensive written instructions the client can review when feeling better. Option a is incorrect because repeating all instructions to an anxious and dyspneic client overwhelms their already impaired cognitive processing capacity, increases frustration and anxiety, and does not improve information retention during acute respiratory distress. Option b is incorrect because delaying discharge solely for anxiety resolution is impractical and unnecessary when the client can be safely discharged with written materials, as anxiety in COPD often persists and may actually worsen in the hospital setting. Option c is incorrect because while involving family members is beneficial for reinforcement, relying solely on a family member removes the client from their own care participation and does no

Correct Answer: Weak thready pulse and fingernail polish

Option b is correct because a weak thready pulse indicates poor peripheral perfusion which reduces the signal quality needed for accurate pulse oximetry, and fingernail polish interferes with light transmission through the nail bed, both producing unreliable readings. Option a is incorrect because a low-grade fever does not significantly affect pulse oximetry accuracy, and bruising on the hand does not interfere with the light absorption technology used by the pulse oximeter sensor to detect oxygen saturation levels. Option c is incorrect because normal blood pressure suggests adequate perfusion and warm hands indicate good peripheral circulation, both of which support accurate pulse oximetry readings rather than causing the nurse to question measurement reliability. Option d is incorrect because supplemental oxygen and recent ambulation are clinical variables that affect the actual oxygen saturation level rather than the reliability of the pulse oximetry device measurement, making the

Correct Answer: High-flow oxygen suppresses breathing drive

Option c is correct because chronic emphysema clients who retain carbon dioxide may depend on hypoxic drive for respiratory stimulation, and delivering high-flow oxygen can dangerously suppress this drive, leading to respiratory depression and potential respiratory arrest. Option a is incorrect because while nasal mucosal drying can occur at higher flow rates, this is a comfort concern managed with humidification rather than the primary clinical danger associated with excessive oxygen administration in chronic COPD clients. Option b is incorrect because nasal cannula devices can deliver oxygen up to six liters per minute, so equipment limitation is not the reason for avoiding high-flow oxygen in this emphysema client with chronic carbon dioxide retention. Option d is incorrect because while oxygen orders require provider authorization, the experienced nurse's primary teaching point should address the clinical rationale for maintaining low-flow oxygen rather than simply citing scop
