1. Which client is at risk for hypomagnesemia?

• A. Client with a history of heart disease
• B. Client taking magnesium-based antacids
• C. Client with a parathyroid disorder
• D. Client admitted with alcohol abuse

Correct answer: D

Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.

2. The nurse is caring for a client with full-thickness burns to the left arm and trunk. What is the priority for this client?

• A. Pain management
• B. Airway assessment
• C. Fluid volume status monitoring
• D. Risk for infection prevention

Correct answer: C

Rationale: Correct! With full-thickness burns, there is a significant risk of fluid loss through the burn wound and fluid shift, leading to hypovolemia and shock. Monitoring and maintaining the client's fluid volume status is crucial to prevent complications like hypovolemic shock. Pain management (Option A) is essential but not the priority in this situation. While airway assessment (Option B) is crucial, it is typically assessed first in clients with respiratory distress. Preventing infection (Option D) is important but managing fluid volume status takes precedence in the initial care of a client with full-thickness burns.

3. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

4. During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?

• A. Aspirin
• B. Diazoxide
• C. Procardia
• D. Mannitol

Correct answer: C

Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.

5. Nursing care for a client undergoing chemotherapy includes assessment for signs of bone marrow depression. Which finding accounts for some of the symptoms related to bone marrow depression?

• A. erythrocytosis
• B. leukocytosis
• C. polycythemia
• D. thrombocytopenia

Correct answer: D

Rationale: Thrombocytopenia is an abnormal decrease in the number of platelets, which results in bleeding tendencies. During chemotherapy, bone marrow depression can lead to a reduction in platelet production, causing thrombocytopenia. Erythrocytosis is an abnormal increase in red blood cells, leukocytosis is an increase in white blood cells, and polycythemia is an excess of red blood cells, which is synonymous with erythrocytosis. In the context of chemotherapy, the focus is on the decrease in red and white blood cells, making thrombocytopenia the most relevant finding.
