Correct Answer: C

Rationale: The correct instruction for the nurse to include in the teaching for a client with GERD is to eat small, frequent meals throughout the day. This recommendation helps reduce symptoms by preventing the stomach from becoming overly full, which can increase pressure on the lower esophageal sphincter and lead to acid reflux. Choices A, B, and D are incorrect because increasing fluid intake with meals can exacerbate GERD symptoms, lying down after eating can worsen reflux, and consuming spicy foods can trigger acid reflux in individuals with GERD.

Correct Answer: B

Rationale: Vertigo is the primary symptom of Meniere's disease and can lead to falls and other injuries. Ensuring safety and addressing the risk of injury is the nurse's top priority. While social isolation and impaired hearing are significant concerns associated with Meniere's disease, the immediate danger of falls due to vertigo takes precedence in the plan of care. Impaired verbal communication, although important, is not as urgent as preventing injuries caused by vertigo.

Correct Answer: B

Rationale: Fixed, dilated pupils are a sign of increased intracranial pressure or brain injury, indicating a potentially serious neurological condition. Flaccid paralysis, although concerning, may not always indicate immediate life-threatening issues. Diminished spinal reflexes and reduced sensory responses are important neurological assessments but are not as acutely concerning as fixed, dilated pupils in this context.

Correct Answer: A

Rationale: The correct answer is to increase fluid intake to prevent crystalluria, a potential side effect of ciprofloxacin. Crystalluria is the formation of crystals in the urine, which can be reduced by maintaining adequate hydration. Choice B is incorrect because ciprofloxacin can be taken with or without food. Choice C is incorrect as avoiding sunlight exposure is more relevant for medications that cause photosensitivity, not typically a concern with ciprofloxacin. Choice D is less essential than choice A because while reporting changes in urine color is important, preventing crystalluria through adequate fluid intake is a higher priority.

Correct Answer: C

Rationale: The correct answer is C: 'Decreased edema and improved peripheral pulses.' In a client with heart failure, furosemide is a diuretic that helps reduce fluid overload. Therefore, a decrease in edema (swelling due to fluid retention) and improved peripheral pulses (indicating better circulation) are signs that the medication is effective. Choices A, B, and D are incorrect. Increased urine output and weight loss (Choice A) may indicate the diuretic effect of furosemide but do not specifically reflect its effectiveness in heart failure. Increased heart rate and blood pressure (Choice B) are not desired effects of furosemide and may suggest adverse reactions. Decreased shortness of breath and clear lung sounds (Choice D) are related to improved respiratory status and may not directly reflect the effectiveness of furosemide in addressing fluid overload.
