Correct Answer: A

Rationale: The correct answer is A: Blood pressure measurement. Dizziness and weakness can be symptoms of hypotension or low blood pressure. Prioritizing blood pressure measurement is crucial because it can indicate if the patient is at risk of complications like cardiovascular collapse. Pulse oximetry (B) is important for assessing oxygen levels in the blood but may not directly address dizziness and weakness. Blood glucose levels (C) are important but not the priority in this scenario. Cardiac monitoring (D) may be necessary but should come after assessing blood pressure to rule out immediate life-threatening conditions.

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: A

Rationale: The correct answer is A because avoiding environmental allergens and cold air can help prevent asthma attacks. This shows the patient understands the importance of managing triggers. Choice B is incorrect because over-the-counter medications may not be sufficient for asthma management. Choice C is incorrect because smoking can worsen asthma symptoms. Choice D is incorrect because using the inhaler only when feeling short of breath is not a proactive approach to managing asthma triggers.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): Promoting activity is the most prioritized nursing intervention for a client with CHF. Activity helps improve cardiac function, decreases fluid accumulation, and enhances overall cardiovascular health. It also prevents complications like muscle weakness and deconditioning. It is crucial in managing CHF symptoms and improving the client's quality of life. Summary of Incorrect Choices: A: Administering diuretics helps in reducing fluid overload but does not address the underlying issue of improving cardiac function through physical activity. B: Limiting fluid intake is important, but promoting activity takes precedence as it directly impacts cardiac function and fluid accumulation. D: Maintaining fluid balance is necessary but is a broad concept that includes various interventions, with promoting activity being more focused and critical in CHF management.

Correct Answer: A

Rationale: Rationale: 1. Collecting a follow-up database ensures up-to-date information. 2. It allows for monitoring of medication effectiveness and any new symptoms. 3. Checking the blood pressure is essential but needs current context. 4. Asking the patient to read her record may not provide all necessary updates. 5. The complete health history is crucial but obtaining it first may delay urgent blood pressure check.
