Correct Answer: B

Rationale: The correct answer is to instruct the client to chew sugarless gum. Chewing sugarless gum can help alleviate dry mouth by stimulating saliva production, which is a common side effect of many antidepressants. Decreasing fluid intake (choice A) is not recommended as it can worsen dry mouth. Avoiding mouthwash (choice C) is not as effective as chewing gum in stimulating saliva. Increasing intake of dairy products (choice D) is not directly related to managing dry mouth caused by antidepressants.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a client with a pulmonary embolism. Pulmonary embolism can lead to impaired gas exchange, causing hypoxemia. Administering oxygen helps to maintain adequate oxygenation levels. Thoracentesis is not indicated for a pulmonary embolism, as it is a procedure to remove fluid or air from the pleural space, not a treatment for embolism. Elevating the client's lower extremities is not a priority in the management of a pulmonary embolism. Administering anticoagulant therapy is important in the treatment of pulmonary embolism to prevent further clot formation, but it is not the first intervention. Oxygen administration takes precedence to address the immediate oxygenation needs of the client.

Correct Answer: C

Rationale: The correct answer is C. An SPF of at least 15 is recommended to effectively protect against harmful UV rays. A sunscreen with an SPF of 10 is insufficient and does not provide adequate protection against skin cancer. Choices A, B, and D demonstrate good understanding of sun protection measures, such as avoiding peak sun hours, wearing protective clothing like a wide-brimmed hat, and reapplying sunscreen every 2 hours, which are all effective strategies to prevent skin cancer.

Correct Answer: C

Rationale: Offering to go for a walk with the client helps redirect their energy in a non-confrontational way, avoiding escalation of aggressive behavior while promoting de-escalation.

Correct Answer: B

Rationale: Asking the client what the voices are saying is the priority action as it helps assess the content of the hallucinations. This assessment is crucial to determine if the client is at risk of harm to themselves or others. Encouraging the client to listen to music or providing a distraction may not address the underlying issues related to the hallucinations. Administering antipsychotic medication, although important, should come after a thorough assessment of the hallucinations to ensure the right medication and dosage are provided.
