Correct Answer: D

Rationale: Teaching the individual to limit sugar and caffeine intake is an appropriate intervention to reduce anxiety and improve sleep quality. Sugar and caffeine can exacerbate anxiety symptoms and disrupt sleep patterns. By reducing their intake, the individual may experience a decrease in anxiety levels and better sleep. Encouraging daily rituals, reinforcing financial realities, or suggesting alcohol consumption before bed are not evidence-based strategies for managing anxiety and sleeplessness.

Correct Answer: C

Rationale: In clients with congestive heart failure (CHF), impaired cardiac function can lead to decreased renal perfusion, resulting in elevated serum creatinine levels. Therefore, an increased serum creatinine level is a common laboratory finding in CHF clients, indicating possible renal impairment.

Correct Answer: D

Rationale: Seizures in a client with suspected meningitis indicate increased intracranial pressure or other complications requiring immediate intervention. Seizures can lead to further neurological damage and need prompt management to prevent adverse outcomes. Therefore, addressing seizures promptly is crucial in the care of a client with suspected meningitis.

Correct Answer: C

Rationale: In this scenario, it is crucial to maintain the client's confidentiality while ensuring her safety. Contacting a person chosen by the client to remove the weapon from her home is the best course of action. This approach respects the client's autonomy and helps reduce the risk of harm without involving external authorities unnecessarily.

Correct Answer: B

Rationale: An Intracranial Pressure (ICP) of 20 mm Hg is at the upper limit of normal and may indicate increased intracranial pressure, which is a critical finding in a client with a severe head injury. Elevated ICP can lead to further brain damage and must be addressed promptly to prevent complications such as herniation. Monitoring and managing ICP are crucial in the care of patients with head injuries in the ICU.
