1. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

2. A child with suspected bacterial meningitis is under the care of a nurse. Which action should the nurse prioritize?

• A. Administer antibiotics as prescribed.
• B. Maintain the child on NPO status.
• C. Monitor the child's intake and output.
• D. Implement seizure precautions.

Correct answer: D

Rationale: The priority action for a child with suspected bacterial meningitis is to implement seizure precautions. Meningitis can lead to increased intracranial pressure, which may trigger seizures. By implementing seizure precautions, such as padding the side rails of the bed and ensuring a clear environment, the nurse aims to prevent injury during a potential seizure episode, prioritizing the child's safety. Administering antibiotics as prescribed is essential in treating bacterial meningitis, but seizure precautions take precedence due to the immediate risk of injury. Maintaining NPO status and monitoring intake and output are important aspects of care but are not the priority when considering the risk of seizures.

3. The patient with bipolar disorder is being treated with lithium and has a new prescription for captopril for hypertension. The combination of these two drugs makes which assessment particularly important?

• A. Potassium level
• B. Lithium level
• C. Creatinine level
• D. Blood pressure

Correct answer: B

Rationale: When captopril, an ACE inhibitor, is combined with lithium, it can lead to lithium accumulation. Therefore, monitoring lithium levels is crucial to prevent toxicity. While ACE inhibitors like captopril can cause hyperkalemia, renal insufficiency, and hypotension, the risk of these effects is not increased by the combination of lithium and captopril.

4. The nurse is providing care for a pediatric client in the emergency department (ED) with a diagnosis of decreased level of consciousness (LOC) secondary to increased intracranial pressure (ICP). Which healthcare provider order should the nurse question?

• A. Passive range-of-motion exercises to promote hip flexion
• B. Oxygen at 2 L nasal cannula to maintain saturation above 95%
• C. Hourly vital signs and neurologic checks
• D. Elevate head of bed 30 degrees

Correct answer: A

Rationale: In a pediatric client with increased intracranial pressure (ICP) and decreased level of consciousness (LOC), passive range-of-motion exercises to promote hip flexion should be questioned as they can potentially increase intracranial pressure. This action may not be safe for the client's condition. The other options are appropriate interventions for managing a pediatric client with increased ICP and decreased LOC.

5. What is the priority nursing intervention when caring for a neonate born with bladder exstrophy?

• A. Measuring intake and output
• B. Inserting a Foley catheter
• C. Covering the defect with sterile plastic wrap
• D. Palpating the bladder mass to ensure urine is expelled

Correct answer: C

Rationale: The priority nursing intervention when caring for a neonate born with bladder exstrophy is to cover the defect with sterile plastic wrap. This intervention helps prevent infection and maintains a moist environment, promoting optimal healing and reducing the risk of complications.
