Correct Answer: D

Rationale: To prevent Otitis Externa, it is important to remove water from the ears after showering or swimming. This helps reduce the risk of moisture buildup in the ear canal, which can lead to infection. Cleaning the ear with a cotton-tipped swab daily can actually increase the risk of injury or infection. Placing earplugs in the ears when sleeping at night may trap moisture and promote bacterial growth. Using a cool water irrigation solution to remove earwax is not recommended as it can disrupt the natural balance of the ear canal.

Correct Answer: D

Rationale: When educating a client about Buspirone, the nurse should highlight that this medication has a low risk for physical or psychological dependence or tolerance. This information is crucial for the client to understand the safety profile of Buspirone compared to other medications used for anxiety.

Correct Answer: B

Rationale: Dopamine, when administered at a low dose, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.

Correct Answer: C

Rationale: The correct instruction for a client starting Metoprolol is to avoid sudden changes in position. Metoprolol can cause orthostatic hypotension, leading to dizziness and falls if the client changes positions quickly. By advising the client to make position changes slowly, the nurse helps prevent these adverse effects and promotes safety.

Correct Answer: B

Rationale: The nurse should monitor the client's serum lithium levels to ensure they are within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels is crucial because lithium has a narrow therapeutic range, and levels outside this range can lead to toxicity, which can be life-threatening. Therefore, regular monitoring is essential to prevent adverse effects and ensure the medication's effectiveness.
