Correct Answer: B

Rationale: Step-by-step rationale for choice B being correct: 1. Blood pressure is vital in this scenario due to prednisone discontinuation. 2. Abruptly stopping prednisone can lead to adrenal insufficiency. 3. Adrenal insufficiency can cause hypotension, a life-threatening condition. 4. Monitoring blood pressure can help detect and manage potential complications. Summary of other choices: A: Breath sounds – Important but not the priority in this specific situation. C: Capillary refill – Useful for assessing circulation but not urgent in this context. D: Butterfly rash – A characteristic of lupus, but not a critical concern in this scenario.

Correct Answer: C

Rationale: The correct answer is C: 0.45% saline. This solution is hypotonic because it has a lower osmolarity compared to the intracellular fluid. It contains fewer solutes than the cells, causing water to move into the cells by osmosis, potentially causing them to swell. Normal saline (A) and Ringer's lactate (B) are isotonic solutions, meaning they have a similar osmolarity to the intracellular fluid and do not cause significant water shifts. 5% dextrose in normal saline (D) is a hypertonic solution, containing more solutes than the cells, leading to water movement out of the cells.

Correct Answer: A

Rationale: The correct answer is A: Where is the pain located? This question corresponds to the "P" in PQRST, which stands for Provocation/Palliation. By asking where the pain is located, the nurse is gathering information about what triggers or relieves the pain, aiding in the assessment of the chest pain. The other choices are incorrect because: B: What causes the pain? - This question corresponds to the "Q" in PQRST, which stands for Quality. It focuses on understanding the characteristics of the pain, not the cause. C: Does it come and go? - This question corresponds to the "R" in PQRST, which stands for Radiation. It pertains to whether the pain spreads to other areas, not if it comes and goes. D: What does the pain feel like? - This question corresponds to the "S" in PQRST, which stands for Severity. It relates to the intensity of the pain, not its location.

Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. Increased thirst and polyuria are symptoms of hypercalcemia, as excess calcium can lead to dehydration and increased urine output. Decreased muscle tone is also a common symptom of hypercalcemia. The lab value of Ca 8 mg/dl confirms high levels of calcium in the blood. Incorrect choices: A: Hypocalcemia - This is incorrect as the lab value of Ca 8 mg/dl indicates normal to high levels of calcium, ruling out hypocalcemia. B: Hyperkalemia - This is incorrect as the lab value of K 4 mEq/L is within normal range, ruling out hyperkalemia. D: Hypochloremia - This is incorrect as the lab value of Cl 103 mEq/L is within normal range, ruling out hypochloremia.

Correct Answer: C

Rationale: The correct answer is C: Raw fruits and vegetables. Patients with HIV and diarrhea should avoid raw fruits and vegetables due to their high fiber content, which can exacerbate diarrhea symptoms. Fiber can increase bowel movements and worsen diarrhea. Therefore, avoiding raw fruits and vegetables can help reduce diarrhea. Choice A (Potassium-rich food) is not the best answer because potassium-rich foods are important for patients with HIV to maintain electrolyte balance. Choice B (Liquid nutritional supplements) can actually be beneficial in providing essential nutrients to patients with HIV. Choice D (Frozen products) is not directly related to diarrhea management in patients with HIV.
