Correct Answer: A

Rationale: Administering an antiemetic before meals is a crucial intervention to manage chemotherapy-induced nausea. Antiemetics help prevent or reduce nausea and vomiting associated with chemotherapy. Providing frequent mouth care (choice B) is important for managing oral mucositis but not specifically for nausea. Encouraging small, frequent meals (choice C) and offering clear liquids (choice D) are beneficial strategies for managing gastrointestinal side effects but may not be as effective in controlling nausea as administering antiemetics.

Correct Answer: C

Rationale: The correct answer is C, 'Presence of uremic frost.' Increased heart rate, visual disturbances, and decreased mentation are all signs and symptoms indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Uremic frost, however, is not associated with HHNS but is a clinical finding seen in severe cases of chronic kidney disease. Therefore, the nurse should report the presence of uremic frost to the healthcare provider as a separate concern from HHNS.

Correct Answer: A

Rationale: The correct action the nurse should take first is to refer the client to a healthcare provider for a pelvic examination. This is important to rule out serious conditions that may be causing the abdominal pain and dysmenorrhea. While notifying the parents, determining the date of the client's last menstrual period, and asking the client to lie down for a pelvic examination could be necessary steps, the priority is to ensure a proper evaluation by a healthcare provider to address the client's presenting symptoms effectively.

Correct Answer: A

Rationale: The correct answer is 'Ineffective airway clearance.' Following a ureter lithotomy via a flank incision, the highest priority nursing problem is ensuring the client's airway remains clear. This is crucial for effective breathing and oxygenation. Altered nutrition, fluid volume excess, and activity intolerance are important to address but are of lower priority compared to maintaining a clear airway postoperatively.

Correct Answer: A

Rationale: The correct intervention for a child with Leukemia undergoing chemotherapy and experiencing altered nutrition, less than body requirements due to anorexia, nausea, and vomiting is to allow the child to eat foods desired and tolerated. This intervention helps improve the child's nutrition intake during chemotherapy. Choice B is incorrect because restricting foods may further limit the child's nutritional intake. Choice C is incorrect because recommending eating the same foods as siblings may not align with the child's preferences or needs during treatment. Choice D is incorrect as encouraging large portions of food at every meal may overwhelm the child and be counterproductive to their nutritional needs.
