Which assessment finding should indicate to the nurse that a client with arterial hypertension is experiencing a cardiac complication?

A. Complaints of an occipital headache

B. A palpable dorsal pedis pulse bilaterally

C. Complaints of shortness of breath on exertion

D. A blood pressure of 160/90

Correct Answer: C
Rationale: The correct answer is C, complaints of shortness of breath on exertion. This symptom is indicative of heart failure, a common cardiac complication of arterial hypertension. Shortness of breath on exertion is often due to the heart's inability to pump effectively, leading to fluid buildup in the lungs. Choices A, B, and D are incorrect because complaints of an occipital headache, a palpable dorsal pedis pulse bilaterally, and a blood pressure of 160/90 do not specifically indicate a cardiac complication in a client with arterial hypertension.

A nurse is caring for a client who is receiving morphine sulfate via a patient-controlled analgesia (PCA) pump. Which action is most important for the nurse to implement?

• A. Monitor the client's respiratory status
• B. Teach the client how to use the PCA pump
• C. Evaluate the client's pain level
• D. Assess the client's pain level

Correct Answer: A
Rationale: When a client is receiving opioids like morphine sulfate via a PCA pump, the most critical action for the nurse to implement is to monitor the client's respiratory status. Opioids can cause respiratory depression, which can be life-threatening. Monitoring respiratory status allows for early detection of any signs of respiratory compromise. Teaching the client how to use the PCA pump, evaluating pain level, and assessing pain level are important aspects of care but ensuring the client's safety by monitoring respiratory status takes precedence due to the potential risks associated with opioid administration.

A client who is HIV positive and taking lamivudine (Epivir) calls the clinic to report a cough and fever. What action should the nurse implement?

• A. Advise the client to come to the clinic for an evaluation
• B. Advise the client to increase fluid intake
• C. Advise the client to take an over-the-counter cough suppressant
• D. Advise the client to rest and call if the fever persists

Correct Answer: A
Rationale: The correct action for the nurse to implement in this situation is to advise the client to come to the clinic for an evaluation. Given the client's HIV-positive status and medication, it is crucial to assess the cough and fever promptly to identify the underlying cause. Increasing fluid intake (choice B) may be beneficial but does not address the need for evaluation. Taking an over-the-counter cough suppressant (choice C) may not be appropriate without knowing the cause of the symptoms. Advising the client to rest and call if the fever persists (choice D) delays the necessary evaluation and treatment.

A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?

• A. Reposition the nasal cannula
• B. Lower the oxygen rate
• C. Encourage the client to cough and deep breathe
• D. Monitor the client's oxygen saturation level

Correct Answer: B
Rationale: In this scenario, the client with COPD receiving increased oxygen is experiencing oxygen toxicity, leading to lethargy and confusion. Lowering the oxygen rate is the priority action to prevent further harm. Repositioning the nasal cannula, encouraging coughing and deep breathing, and monitoring oxygen saturation are all important interventions, but the immediate concern is to address the oxygen toxicity by lowering the oxygen rate.

In preparing to administer a scheduled dose of intravenous furosemide (Lasix) to a client with heart failure, the nurse notes that the client's B-Type Naturetic peptide (BNP) is elevated. What action should the nurse take?

• A. Measure the client's oxygen saturation before taking further action
• B. Administer a PRN dose of nitroglycerin (Nitrostat)
• C. Administer the dose of furosemide as scheduled
• D. Hold the dose of furosemide until contacting the healthcare provider

Correct Answer: C
Rationale: Administering the scheduled dose of furosemide is appropriate when a client with heart failure has an elevated BNP level. BNP elevation indicates fluid overload, and furosemide is a diuretic that helps in reducing excess fluid. Measuring the client's oxygen saturation (Choice A) is not directly related to addressing fluid overload. Administering nitroglycerin (Choice B) is not indicated for managing elevated BNP levels. Holding the furosemide dose (Choice D) would delay appropriate treatment for fluid overload.
