Correct Answer: A

Rationale: The correct answer is A: Administering an oral dose of levothyroxine (Synthroid). In myxedema coma, there is severe hypothyroidism leading to altered mental status, hypothermia, and organ failure. Administering levothyroxine is crucial to replace the deficient thyroid hormone rapidly and restore metabolic function. Warming the client (B) is important but secondary to addressing the underlying hormonal imbalance. Measuring intake and output (C) is essential for overall assessment but not the most critical intervention. Maintaining a patent airway (D) is always important in any medical emergency but does not directly address the primary issue of hypothyroidism in myxedema coma.

Correct Answer: B

Rationale: The correct answer is B: Fluorouracil (5-fluorouracil, 5-FU). Fluorouracil is a commonly used chemotherapy drug for treating advanced liver cancer. It works by inhibiting the growth of cancer cells. This drug is specifically effective in targeting rapidly dividing cells, which is a characteristic of cancer cells. Fluorouracil is often used in combination with other chemotherapy drugs to improve treatment outcomes. Summary of other choices: A: Fluoxymesterone (Halotestin) - This is an androgen hormone used to treat certain types of breast cancer, not liver cancer. C: Tamoxifen (Nolvadex) - This is a hormonal therapy drug used in breast cancer, not liver cancer. D: Megestrol (Megace) - This is a hormonal therapy drug used for certain types of cancers, but not typically for liver cancer.

Correct Answer: B

Rationale: The correct answer is B: Phenytoin (Dilantin). Phenytoin is known to cause gingival hyperplasia as a side effect, which can be minimized with good oral hygiene practices. Procainamide, Azathioprine, and Allopurinol are not associated with gingival hyperplasia. Therefore, the client receiving cyclosporine should focus on practicing good oral hygiene specifically when taking Phenytoin to minimize the risk of developing gingival hyperplasia.

Correct Answer: C

Rationale: The correct answer is C: Weighing the client before and after the procedure. This is crucial as it helps monitor fluid removal during dialysis, ensuring the process is effective and safe. Weighing helps determine if the correct amount of fluid has been removed. A: Keeping dialysis supplies in a clean area is important for infection control but not a direct responsibility during the procedure. B: Inspecting the catheter insertion site for signs of infection is essential for monitoring the site's health but not a direct responsibility during dialysis. D: Washing hands before and after handling the catheter is a general infection control measure but not specific to the dialysis procedure itself.

Correct Answer: D

Rationale: The correct answer is D (Lamb and peaches) because lamb 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. Peaches are high in vitamin C, which enhances iron absorption. Shrimp and tomatoes (A) have some iron but are not as rich in iron as lamb. Cheese and bananas (B) are not significant sources of iron. Lobster and squash (C) also do not provide as much iron as lamb. Overall, the combination of heme iron from lamb and vitamin C from peaches makes them the most suitable choices for an anemic client requiring iron therapy.
