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.

Correct Answer: C

Rationale: The correct answer is C: subjective. Subjective data refers to information provided by the patient based on their feelings, perceptions, and experiences. In this case, the patient's report of feeling nervous, nauseated, and hot is subjective because it reflects their personal sensations and cannot be measured or observed directly by the nurse. Objective data (choice A) is measurable and observable, such as vital signs or physical examination findings. Reflective (choice B) and introspective (choice D) do not accurately describe the type of data provided by the patient in this scenario. The patient's symptoms are subjective because they are based on the patient's own feelings and experiences, making choice C the most appropriate answer.

Correct Answer: A

Rationale: The correct answer is A: Administer antiemetics. Antiemetics help alleviate nausea and vomiting by blocking neurotransmitters in the brain. This intervention directly targets the symptoms and provides relief for the client. Administering fluids (B) may help with hydration but does not address the root cause. Administering analgesics (C) is for pain relief, not for nausea and vomiting. Monitoring electrolytes (D) is important but does not directly treat the symptoms. Therefore, administering antiemetics is the most appropriate intervention for severe nausea and vomiting.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Oxygen administration is the first intervention for shock as it helps improve oxygenation to vital organs. Lack of oxygen can worsen shock. Administering IV fluids (choice B) could be the second step to improve perfusion. Monitoring respiratory rate (choice C) is important but not the first intervention. Administering pain medication (choice D) is not a priority in managing shock.

Correct Answer: A

Rationale: The correct answer is A: Perform a CT scan. This is the priority action because it helps determine if the stroke is ischemic or hemorrhagic, guiding treatment decisions. Monitoring blood pressure (B) is important but not the priority. Administering aspirin (C) can be considered after confirming the type of stroke. Administering thrombolytics (D) is indicated for ischemic stroke but should only be done after ruling out hemorrhagic stroke with a CT scan.
