Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. A client is admitted with a diagnosis of myocardial infarction (MI). Which intervention is a priority during the acute phase?

• A. Administer morphine for pain relief
• B. Encourage the client to perform isometric exercises
• C. Position the client flat in bed
• D. Restrict fluid intake

Correct answer: A

Rationale: During the acute phase of a myocardial infarction (MI), the priority intervention is to administer morphine for pain relief. Morphine not only alleviates pain but also reduces myocardial oxygen demand, which is crucial in the management of MI. Encouraging the client to perform isometric exercises (choice B) can increase myocardial oxygen demand and should be avoided during the acute phase. Positioning the client flat in bed (choice C) may worsen symptoms by increasing venous return and workload on the heart. Restricting fluid intake (choice D) is not a priority intervention during the acute phase of MI; maintaining adequate hydration is important for organ perfusion.

3. The client with a new colostomy is being taught about colostomy care. Which statement by the client indicates effective learning?

• A. I will change my colostomy bag every day.
• B. I should eat a low-fiber diet.
• C. I need to inspect the stoma daily for color and swelling.
• D. I can skip my colostomy care if I feel well.

Correct answer: C

Rationale: The correct answer is C because inspecting the stoma daily is crucial in identifying any early signs of complications or infections. Choice A is incorrect because changing the colostomy bag daily is not necessary unless there is a specific reason to do so. Choice B is incorrect as a low-fiber diet is not usually recommended for colostomy care. Choice D is incorrect because colostomy care should be performed regularly regardless of how the client feels.

4. The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?

• A. Muscle weakness
• B. Decreased deep tendon reflexes
• C. Constipation
• D. Hypotension

Correct answer: A

Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.

5. When taking blood pressure at the brachial artery, the nurse should place the client's arm in which position?

• A. Slightly above the level of the heart
• B. At the level of the heart
• C. At a level of comfort for the client
• D. Below the level of the heart

Correct answer: B

Rationale: When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.
