Correct Answer: D

Rationale: The correct answer is D: Lupus. Lupus can affect the kidneys, leading to renal impairment. Renal impairment can decrease the body's ability to excrete ammonia, resulting in elevated levels. Renal failure (choice A) can also lead to elevated ammonia levels, but lupus specifically contributes to renal issues. Cirrhosis (choice B) primarily affects the liver, not kidneys. Psoriasis (choice C) is a skin condition and does not directly impact ammonia levels.

Correct Answer: D

Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.

Correct Answer: A

Rationale: The correct answer is A: Encouraging early ambulation to prevent deep vein thrombosis. Early ambulation helps prevent blood clot formation in the legs, reducing the risk of deep vein thrombosis post-surgery. It also promotes circulation and aids in preventing complications like pneumonia. Administering pain medication (B) is important, but preventing complications should take priority. Providing wound care (C) is essential but not the top priority. Encouraging a high-protein diet (D) is beneficial for healing, but immediate post-operative mobility is crucial for preventing complications.

Correct Answer: B

Rationale: The correct answer is B because increasing physical activity and reducing stress are important lifestyle changes for managing chronic hypertension. Exercise helps lower blood pressure and stress reduction techniques can help control hypertension. Option A is incorrect as reducing sodium intake, not increasing it, is recommended. Option C is incorrect as medications for hypertension should be taken as prescribed, not only when blood pressure increases. Option D is incorrect as monitoring blood pressure should be done regularly, but not necessarily every week.

Correct Answer: D

Rationale: The correct answer is D: Scurvy. Scurvy is caused by a deficiency in vitamin C, which is essential for collagen synthesis. Without enough vitamin C, collagen production is impaired, leading to symptoms like bleeding gums, fatigue, and joint pain. Incorrect Choices: A: Rickets is caused by a deficiency in vitamin D, not vitamin C. B: Marasmus is a severe form of malnutrition due to inadequate intake of calories and protein, not specifically vitamin C. C: Kwashiorkor is a form of severe acute malnutrition typically caused by inadequate protein intake, not vitamin C deficiency. In summary, the correct answer is D (Scurvy) because it directly relates to inadequate intake of vitamin C, while the other choices are associated with different nutrient deficiencies.
