Correct Answer: C

Rationale: Administering IV adenosine is the appropriate intervention for a client with symptomatic tachycardia to restore normal sinus rhythm. Adenosine is a medication used to treat supraventricular tachycardia (SVT) by interrupting the reentry pathways through the AV node and restoring normal sinus rhythm. It is a rapid-acting medication given as a rapid IV push followed by a saline flush. The dose is typically administered in a healthcare setting where cardiac monitoring is available due to its potential to cause transient asystole.

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: B

Rationale: Clozapine (Clozaril) is an antipsychotic medication that is known to improve cognitive function and thought clarity in individuals with schizophrenia. It primarily helps in managing symptoms related to thought processes rather than focusing on community function, coping with symptoms, or grooming and hygiene.

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.

Correct Answer: C

Rationale: In cases of major depressive disorder where the client is non-participatory and withdrawn, sitting with the client and providing support without pressuring them to engage in activities like eating or therapy is crucial. This approach respects the client's current state, builds trust, and creates a supportive environment that can eventually lead to the client opening up and accepting help.
