D454 Adult Health III - Set 5 - Part 2

Correct Answer: Ask if wishes were discussed with provider

Option a is correct because the nurse cannot independently place a DNR order and must first determine whether the patient has discussed these wishes with their healthcare provider, who must write the order. Option b is incorrect because nurses do not have the authority to place a DNR order independently in the patient's chart, as this medical order must be written by the healthcare provider after proper discussion and documentation. Option c is incorrect because having the patient sign a consent form is premature before confirming that the healthcare provider has been involved in the conversation, since the provider must formally order the DNR status. Option d is incorrect because contacting the ethics committee is not the first step when a patient expresses end-of-life wishes, as the initial action is ensuring the healthcare provider is aware and can write appropriate orders.

Correct Answer: Early as part of the initial care plan

Option c is correct because advance directives should be addressed early in a terminal admission as part of the initial plan of care, ensuring the patient's wishes are documented before any emergencies arise. Option a is incorrect because waiting until the patient deteriorates may result in the patient being unable to communicate their wishes, which defeats the purpose of proactive advance directive planning during admission. Option b is incorrect because relying on the family to initiate the discussion places the burden inappropriately and may result in advance directives never being addressed if the family avoids the topic of death. Option d is incorrect because discussing advance directives during the final days may be too late if the patient has lost decision-making capacity, and early planning ensures wishes are honored throughout the entire admission.

Correct Answer: Unconscious with no brain stem activity

Option b is correct because brain death determination requires the patient to be unconscious with no brain stem activity, meaning all brain stem reflexes are absent along with irreversible cessation of function. Option a is incorrect because absence of voluntary muscle movement alone does not constitute brain death, as patients with spinal cord injuries may lack movement but still have intact brain stem function and consciousness. Option c is incorrect because inability to breathe independently is only one component of the assessment, and brain death requires complete absence of all brain stem activity rather than just respiratory function alone. Option d is incorrect because a flat line on a heart monitor indicates cardiac death rather than brain death, and brain dead patients may still have cardiac activity maintained through mechanical ventilation support.

Correct Answer: Anxiety about unfinished business

Option d is correct because planning to resolve family conflicts and settle issues with estranged siblings reflects anxiety about unfinished business, which is a common and psychologically healthy response in terminal patients. Option a is incorrect because planning to resolve family relationships before disease progression actually demonstrates acceptance of the terminal diagnosis rather than denial, as the patient acknowledges limited remaining time. Option b is incorrect because seeking resolution with estranged family members is a healthy coping mechanism that promotes emotional closure, not a dysfunctional response that would disrupt the patient's overall wellbeing. Option c is incorrect because the patient is not expressing beliefs about recovery but rather making practical plans to achieve relationship closure while still physically able to travel, which reflects realistic awareness.

Correct Answer: Ensuring wishes are honored when incapacitated

Option a is correct because advance directives serve the primary purpose of documenting patient wishes regarding end-of-life care so these preferences can be honored when the patient becomes unable to communicate. Option b is incorrect because the primary purpose of advance directives is protecting patient autonomy and ensuring their wishes are followed, not providing legal protection or liability coverage for the hospital. Option c is incorrect because advance directives do not replace the need for healthcare provider orders, as providers must still write appropriate medical orders consistent with the patient's documented wishes and preferences. Option d is incorrect because advance directives are designed to ensure the patient's own wishes are followed, not to grant family members authority to override medical decisions made by the healthcare team.

Correct Answer: White blood cell count of one times ten to the ninth per liter

Option c is correct because a white blood cell count this low represents severe leukopenia, placing the patient at critical risk for overwhelming infection that could quickly become life-threatening without intervention. Option a is incorrect because a platelet count of four hundred thousand is at the upper end of normal range and does not pose the same immediate life-threatening risk as severe leukopenia in this patient. Option b is incorrect because a hemoglobin slightly below normal is a common finding in elderly patients that warrants monitoring but does not present the same urgent danger as critically low white blood cells. Option d is incorrect because a red blood cell count within normal limits is a reassuring finding that does not require urgent intervention, unlike the critically low white blood cell count that demands immediate attention.

Correct Answer: An elevated reticulocyte count

Option a is correct because healthy bone marrow responds to chronic blood loss by increasing red blood cell production and releasing immature reticulocytes into circulation earlier than usual to compensate for losses. Option b is incorrect because a decreased reticulocyte count would suggest bone marrow failure or suppression rather than the expected compensatory response to ongoing chronic blood loss from gastrointestinal bleeding. Option c is incorrect because a reticulocyte count of zero would indicate complete bone marrow failure, which is not the expected physiologic response to chronic bleeding in a patient with functioning marrow. Option d is incorrect because an unchanged reticulocyte count would suggest the bone marrow is not responding appropriately to the ongoing blood loss, when a healthy marrow should increase production to compensate.

Correct Answer: Hemoglobin of eighty-six grams per liter

Option d is correct because a hemoglobin of eighty-six grams per liter is significantly below normal and causes tissue hypoxia, which directly produces the symptoms of dizziness, fatigue, and palpitations. Option a is incorrect because a hematocrit of thirty-eight percent falls within or near the normal range for many patients, and this value alone would not typically cause the significant symptoms of dizziness and palpitations described. Option b is incorrect because a red blood cell count within the normal range would not explain the patient's symptoms of tissue hypoxia, as normal red cell numbers suggest adequate oxygen-carrying capacity in circulation. Option c is incorrect because normal red blood cell indices indicate that individual red cells are of normal size and hemoglobin content, which would not account for the significant symptoms of tissue hypoxia described.

Correct Answer: Pancytopenia

Option b is correct because pancytopenia specifically refers to the simultaneous reduction of all three blood cell lines, including white blood cells, red blood cells, and platelets, which is common in leukemia patients. Option a is incorrect because disseminated intravascular coagulation is a coagulopathy involving abnormal clotting factor consumption throughout the body, not a primary disorder of reduced blood cell production in the marrow. Option c is incorrect because isolated thrombocytopenia refers only to a decrease in platelets, not the combined reduction of all three cell lines that defines the broader condition of pancytopenia. Option d is incorrect because iron deficiency anemia primarily affects red blood cells and hemoglobin levels, and does not cause the simultaneous decrease in white blood cells and platelets seen in pancytopenia.

Correct Answer: Tissue hypoxia from reduced oxygen delivery

Option a is correct because anemia reduces the blood's oxygen-carrying capacity through low hemoglobin, resulting in tissue hypoxia that causes symptoms of dizziness, shortness of breath, and fatigue even at rest. Option b is incorrect because excess white blood cells blocking circulation describes a different pathologic process such as leukostasis, not the mechanism by which anemia causes dizziness and shortness of breath in patients. Option c is incorrect because elevated platelets causing blood thickening relates to thrombocytosis, not anemia, and the symptoms described are classic manifestations of reduced oxygen delivery rather than increased blood viscosity. Option d is incorrect because increased red blood cell production is actually the bone marrow's compensatory response to anemia, not the cause of symptoms, as the body attempts to restore adequate oxygen-carrying capacity.

Correct Answer: Neutralizing circulating thrombin in the blood

Option d is correct because heparin neutralizes circulating thrombin, which is the central driver of the pathological clotting cascade in DIC, thereby helping to slow the consumption of clotting factors and platelets. Option a is incorrect because reducing blood viscosity is not the primary mechanism of heparin in DIC treatment, as the therapeutic goal is interrupting the pathological thrombin-driven clotting cascade consuming coagulation factors. Option b is incorrect because while platelet aggregation occurs in DIC, heparin's primary therapeutic action targets circulating thrombin rather than directly preventing platelet aggregation at individual clot formation sites throughout the body. Option c is incorrect because heparin does not neutralize plasmin, which is actually part of the fibrinolytic system that breaks down clots, and neutralizing plasmin would worsen rather than improve the clotting problem.

Correct Answer: Clotting factors are consumed causing both problems

Option c is correct because in DIC the widespread microvascular clotting consumes available clotting factors and platelets, which then leaves the body unable to form clots where needed, resulting in simultaneous bleeding. Option a is incorrect because DIC is a single pathological process where the excessive activation of clotting throughout small vessels depletes the body's coagulation resources, causing both clotting and bleeding simultaneously. Option b is incorrect because bleeding in DIC is not limited to surgical sites but occurs from multiple locations throughout the body due to the systemic depletion of clotting factors and platelets from widespread coagulation. Option d is incorrect because the bleeding in DIC is caused by the underlying consumptive coagulopathy itself rather than medication side effects, as the body literally runs out of clotting resources from excessive clot formation.

Correct Answer: Depletion of platelets and clotting factors

Option a is correct because the bleeding manifestations of DIC result from depletion of platelets and clotting factors that have been consumed by the widespread pathological clotting occurring throughout the microvasculature. Option b is incorrect because excessive red blood cell production does not cause bleeding from multiple sites, and polycythemia is an entirely different condition unrelated to the consumptive coagulopathy occurring in DIC. Option c is incorrect because while allergic reactions to blood products can occur, the pattern of oozing from multiple sites with petechiae in a DIC patient is caused by the underlying coagulopathy rather than an allergic response. Option d is incorrect because primary bone marrow failure would present as pancytopenia with gradual onset, not the acute consumptive coagulopathy pattern of simultaneous clotting and bleeding characteristic of DIC pathology.

Correct Answer: Transfusing fresh frozen plasma

Option d is correct because fresh frozen plasma directly provides all clotting factors and works within minutes to restore clotting ability, making it the fastest intervention for replacing depleted factors in active bleeding. Option a is incorrect because vitamin K requires hours to take effect and depends on a functioning liver to synthesize clotting factors, making it too slow for a patient who is actively bleeding from depleted factors. Option b is incorrect because oral iron supplements address iron deficiency anemia over weeks to months and have no effect on clotting factor replacement needed for the acute bleeding crisis in DIC. Option c is incorrect because increasing intravenous fluids may help maintain blood volume but does not replace the specific clotting factors that have been consumed, and dilution could actually worsen the coagulopathy further.

Correct Answer: Unexplained bleeding from multiple body sites

Option b is correct because unexplained bleeding from multiple sites is a hallmark early warning sign of DIC, indicating that widespread microvascular clotting is consuming clotting factors and causing systemic bleeding. Option a is incorrect because elevated blood pressure is not a characteristic finding in DIC, and patients with this condition more commonly experience hypotension due to bleeding and the systemic inflammatory response causing it. Option c is incorrect because decreased nighttime urine output alone is a nonspecific finding that does not specifically suggest DIC, although renal involvement can occur later as microvascular clotting affects kidney perfusion and function. Option d is incorrect because increased appetite and weight gain are not associated with DIC, and patients with this serious coagulopathy typically present with acute illness symptoms rather than signs of improved nutritional status.

Correct Answer: Remained completely localized to the cervix

Option c is correct because carcinoma in situ means the cancer cells have not invaded beyond the surface tissue layer, and no lymph node involvement or distant metastasis confirms the cancer is completely localized. Option a is incorrect because the staging specifically indicates no lymph node involvement, which means the cancer has not spread to any nearby lymph nodes and remains confined to its original tissue location. Option b is incorrect because the staging explicitly shows no distant metastasis, confirming the cancer has not spread to distant organs and remains localized entirely to the cervix at this early stage. Option d is incorrect because carcinoma in situ by definition means the cancer has not invaded beyond the surface layer of tissue, so it has not penetrated deeply into surrounding cervical structures or tissues.

Correct Answer: The resting phase where cells are not dividing

Option a is correct because the resting phase is where cells are not actively dividing, and most chemotherapy agents specifically target cells during active division, making dormant resting cells essentially resistant to treatment. Option b is incorrect because cells that are actively replicating their DNA are in a vulnerable phase of the cell cycle where many chemotherapy drugs can effectively interfere with the replication process and destroy them. Option c is incorrect because the phase where chromosomes are separating is an active division phase where cells are particularly susceptible to chemotherapy agents that disrupt the mitotic spindle and cell division process. Option d is incorrect because cells preparing for division are actively progressing through the cell cycle and are therefore susceptible to chemotherapy agents that target the various processes involved in preparing for mitosis.

Correct Answer: Drying of the skin in the treatment area

Option d is correct because radiation therapy damages the sebaceous glands in the treatment area, resulting in decreased oil production and subsequent dry skin known as desquamation in the radiation field. Option a is incorrect because radiation actually decreases rather than increases oil production by damaging the sebaceous glands, leading to dry and potentially irritated skin rather than oilier skin in the treatment area. Option b is incorrect because therapeutic radiation doses are carefully calculated to treat the cancer while minimizing tissue damage, and full-thickness burns are not an expected normal effect of properly administered radiation therapy. Option c is incorrect because radiation therapy clearly affects the overlying skin by damaging sebaceous glands and causing dryness, and telling the patient there will be no changes would be inaccurate and leave them unprepared.

Correct Answer: A person who smokes and drinks alcohol daily

Option c is correct because daily smoking combined with daily alcohol consumption creates a synergistic effect that represents the highest overall risk for pancreatic cancer among the individuals described in this scenario. Option a is incorrect because eating fried foods at age nineteen, while not healthy, does not carry the same synergistic carcinogenic risk for pancreatic cancer as the combined daily exposure to tobacco and alcohol. Option b is incorrect because being overweight with gastroesophageal reflux are general health concerns that do not carry the same level of synergistic pancreatic cancer risk as combined daily smoking and alcohol consumption. Option d is incorrect because while diabetes and older age are associated with pancreatic cancer risk, well-controlled diabetes in a sixty-seven-year-old does not match the synergistic carcinogenic effect of combined daily smoking and drinking.

Correct Answer: The absence of distant metastasis

Option b is correct because the metastasis component of cancer staging specifically indicates whether cancer has spread to distant body sites, and no distant spread corresponds to a classification of no metastasis. Option a is incorrect because tumor size classification refers to the primary tumor's dimensions and local extent, not whether the cancer has traveled to distant organs or parts of the body beyond the original site. Option c is incorrect because lymph node involvement status addresses whether cancer cells have spread to nearby regional lymph nodes, which is a separate staging component from distant metastasis to remote body sites. Option d is incorrect because cellular differentiation grading describes how abnormal the cancer cells appear under a microscope compared to normal cells, not whether the cancer has spread to distant locations in the body.
