1. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

2. What is an ideal goal of treatment set by the nurse in the care plan for a client diagnosed with chronic kidney disease (CKD) to reduce the risk of pulmonary edema?

• A. Maintaining oxygen saturation above 92%
• B. Absence of crackles and wheezes in lung sounds
• C. Maintaining a balanced intake and output
• D. Absence of shortness of breath at rest

Correct answer: C

Rationale: The ideal goal of treatment for a client with chronic kidney disease (CKD) to reduce the risk of pulmonary edema is to maintain a balanced intake and output. This helps in achieving optimal fluid balance, enabling the heart to eject blood effectively without increasing pressure in the left ventricle and pulmonary vessels. While maintaining oxygen saturation above 92% is important for adequate tissue oxygenation, the primary focus in this scenario is fluid balance. Absence of crackles and wheezes in lung sounds is important to assess for pulmonary status, but it is not the primary goal to prevent pulmonary edema specifically. Similarly, absence of shortness of breath at rest is a relevant goal, but the emphasis in CKD management is on fluid balance to prevent pulmonary complications.

3. A young adult asks the nurse about the normal cholesterol level. The nurse tells the client that the total cholesterol level should be maintained at less than:

• A. 140 mg/dL
• B. 200 mg/dL
• C. 250 mg/dL
• D. 300 mg/dL

Correct answer: B

Rationale: The correct answer is B: 200 mg/dL. A normal cholesterol value ranges between 140 and 199 mg/dL. Total cholesterol levels should ideally be maintained at 200 mg/dL or less to reduce the risk of cardiovascular diseases. Choices A, C, and D are incorrect as they exceed the recommended normal range for total cholesterol levels and may increase the risk of developing heart-related issues.

4. The nurse is caring for a patient who is taking trimethoprim-sulfamethoxazole (TMP-SMX). The nurse learns that the patient takes an angiotensin-converting enzyme (ACE) inhibitor. To monitor for drug interactions, the nurse will request an order for which laboratory test(s)?

• A. A complete blood count
• B. BUN and creatinine
• C. Electrolytes
• D. Glucose

Correct answer: C

Rationale: The correct answer is 'C. Electrolytes.' When trimethoprim-sulfamethoxazole (TMP-SMX) is taken with an ACE inhibitor, there is an increased risk of hyperkalemia due to the combined effects on potassium levels. Monitoring electrolytes, specifically potassium, is essential to detect and manage this potential drug interaction. Choices A, B, and D are incorrect because while they are important tests in general patient care, they are not specifically indicated to monitor for the drug interaction between TMP-SMX and ACE inhibitors.

5. After pericardiocentesis for cardiac tamponade, for which signs should the nurse assess the client to determine if tamponade is recurring?

• A. Decreasing pulse
• B. Rising blood pressure
• C. Distant muffled heart sounds
• D. Falling central venous pressure (CVP)

Correct answer: C

Rationale: After pericardiocentesis for cardiac tamponade, the nurse should assess for distant muffled heart sounds that were noted before the procedure. If these sounds return, it could indicate recurring pericardial effusion and potential tamponade. Therefore, the correct answer is the return of distant muffled heart sounds (Option C). Decreasing pulse (Option A) and falling central venous pressure (Option D) are not specific signs of recurring tamponade. Rising blood pressure (Option B) is also not a typical sign of tamponade recurrence; in fact, hypotension is more commonly associated with tamponade.
