Nursing Elites

1. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Decreased pain.
• D. Increased blood viscosity.

Correct answer: A

Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.

2. The client admitted with peripheral vascular disease (PVD) asks the nurse why her legs hurt when she walks. The nurse bases a response on the knowledge that the main characteristic of PVD is:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Slow blood flow.
• D. Thrombus formation.

Correct answer: A

Rationale: The correct answer is A: 'Decreased blood flow.' In peripheral vascular disease (PVD), there is a narrowing or blockage of blood vessels, leading to reduced blood flow to the extremities. This decreased blood flow results in inadequate oxygen supply to the muscles, causing pain, especially during physical activity when oxygen demand increases. Choice B, 'Increased blood flow,' is incorrect because PVD is characterized by impaired blood circulation rather than increased flow. Choice C, 'Slow blood flow,' is not precise as PVD involves a more significant reduction in blood flow. Choice D, 'Thrombus formation,' is related to the formation of blood clots within vessels, which can be a complication of PVD but is not its main characteristic.

3. A male client comes into the emergency department with a serum creatinine of 2.2 mg/dL and a blood urea nitrogen (BUN) of 24 mg/dL. What question should the nurse ask first when taking this client’s history?

• A. Have you been taking any aspirin, ibuprofen, or naproxen recently?
• B. Do you have anyone in your family with renal failure?
• C. Have you had a diet that is low in protein recently?
• D. Has a relative had a kidney transplant lately?

Correct answer: A

Rationale: The correct question to ask the client first is about their recent intake of nephrotoxic medications like aspirin, ibuprofen, or naproxen. Elevated serum creatinine and BUN levels indicate possible renal issues, making it crucial to assess potential causes such as medication-induced nephrotoxicity. Inquiring about family history of renal failure or recent kidney transplants would not provide immediate insights into the client's current renal condition. While a diet low in protein could influence BUN levels, it is important to address medication history first due to the acute presentation in the emergency department.

4. A client with a completed ischemic stroke has a blood pressure of 180/90 mm Hg. Which action should the nurse implement?

• A. Position the head of the bed (HOB) flat.
• B. Withhold intravenous fluids.
• C. Administer a bolus of IV fluids.
• D. Give an antihypertensive medication.

Correct answer: D

Rationale: In a client with a completed ischemic stroke, an elevated blood pressure like 180/90 mm Hg requires immediate intervention to prevent further damage. Giving an antihypertensive medication is essential to reduce the risk of recurrent stroke or complications related to hypertension. Positioning the head of the bed flat, withholding IV fluids, or administering a bolus of IV fluids are not appropriate actions for managing elevated blood pressure in this scenario and may not address the underlying cause of the hypertension or prevent potential complications.

5. A client who has just undergone surgery suddenly experiences chest pain, dyspnea, and tachypnea. The nurse suspects that the client has a pulmonary embolism and immediately sets about:

• A. Preparing the client for a perfusion scan
• B. Attaching the client to a cardiac monitor
• C. Administering oxygen via nasal cannula
• D. Ensuring that the intravenous (IV) line is patent

Correct answer: C

Rationale: When a client who has just undergone surgery experiences sudden chest pain, dyspnea, and tachypnea, indicating possible pulmonary embolism, the immediate priority for the nurse is to administer oxygen via nasal cannula. This intervention aims to improve oxygenation and alleviate respiratory distress, which is crucial in the setting of a potential pulmonary embolism. Preparing the client for a perfusion scan is not the immediate priority as stabilizing the client's respiratory status comes first. While attaching the client to a cardiac monitor is important for monitoring, administering oxygen takes precedence in this situation. Ensuring IV line patency is relevant for overall client care but is not the priority when a client is experiencing respiratory distress requiring immediate intervention.
