Rationale: Correct Answer: D. Antagonize the action of K on the heart Rationale: 1. Calcium gluconate stabilizes cardiac cell membranes during hyperkalemia. 2. By antagonizing the effects of potassium on the heart, it helps prevent life-threatening cardiac arrhythmias. 3. It does not lower potassium levels immediately or prevent transient renal failure. 4. Administering calcium gluconate is specific to addressing the cardiac effects of hyperkalemia, not renal or overall potassium reduction.

Correct Answer: A

Rationale: The correct answer is A: "Would you like to talk to a psychologist about your thoughts and feelings?" This response acknowledges the client's emotional distress and offers professional support. A psychologist can provide counseling and help the client explore their feelings and concerns about end-of-life decisions. Choice B is incorrect because it assumes the client's spiritual beliefs are the primary concern, neglecting the emotional and psychological aspects. Choice C involves more people in the decision-making process without addressing the client's individual needs. Choice D is dismissive and does not offer any support or explore the client's feelings further. In summary, choice A is the best response because it prioritizes the client's emotional well-being and offers appropriate support through professional counseling.

Rationale: The correct answer is D because a class V Pap test finding indicates severe abnormalities, such as high-grade dysplasia or carcinoma in situ. Therefore, the nurse should instruct the client to undergo a biopsy as soon as possible to confirm the diagnosis and initiate appropriate treatment promptly. Choices A, B, and C are incorrect because a class V result is not normal and requires immediate follow-up, rather than waiting or repeating the Pap test at a later time.

Correct Answer: A

Rationale: The correct answer is A: Shrimp and tomatoes. Shrimp is a good source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Tomatoes are rich in Vitamin C, which helps enhance iron absorption. Cheese, bananas, lobster, squash, lamb, and peaches do not provide significant amounts of iron essential for an anemic client. The combination of shrimp and tomatoes offers a balanced approach to increase iron levels effectively.
