1. A client has a long history of hypertension. Which category of medication would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?

Correct answer: D

Rationale: The correct answer is D, Angiotensin-converting enzyme (ACE) inhibitor. ACE inhibitors inhibit the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking this conversion, ACE inhibitors promote vasodilation and improve perfusion to the kidneys. Additionally, ACE inhibitors block the breakdown of bradykinin and prostaglandin, further contributing to vasodilation. They also lead to increased renin and decreased aldosterone levels. These effects help in reducing blood pressure and protecting the kidneys in clients with hypertension. Antibiotics are used to fight infections, histamine blockers reduce inflammation, and bronchodilators widen the bronchi, none of which address the underlying processes involved in slowing the progression of chronic kidney disease (CKD) in hypertensive clients.

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

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.

3. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?

Correct answer: D

Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.

4. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?

Correct answer: A

Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.

5. After a client with peripheral vascular disease undergoes a right femoral-popliteal bypass graft, their blood pressure drops from 124/80 to 94/62. What should the nurse assess first?

Correct answer: B

Rationale: Assessing pedal pulses is crucial in this situation as it helps determine the adequacy of perfusion to the lower extremity following a bypass graft. A decrease in blood pressure postoperatively could indicate decreased perfusion, making the assessment of pedal pulses a priority to ensure proper circulation. Checking IV fluid infusion, nasal cannula oxygen flow rate, or capillary refill time are not the immediate priorities in this scenario and would not provide direct information about perfusion to the affected extremity.
