Correct Answer: B

Rationale: The correct answer is B. An oxygen saturation of 89% indicates hypoxemia, which is below the normal range (usually 95-100%). This finding requires immediate intervention as it signifies inadequate oxygenation. Options A, C, and D are within normal limits and do not indicate an urgent need for intervention. Option A indicates a good oxygen saturation level, option C denotes a normal respiratory rate, and option D suggests a normal heart rate. Therefore, these options do not require immediate intervention compared to the critically low oxygen saturation level of 89% in option B.

Correct Answer: D

Rationale: The correct answer is D. Avoiding processed foods and canned soups is crucial for a client with hypertension on a low-sodium diet because these foods are typically high in sodium content. Fresh fruits and vegetables are generally healthy choices but may still contain some natural sodium. While limiting sodium intake to 2 grams per day is important, specifically avoiding processed foods and canned soups is more critical in this situation. Drinking water is essential for overall health but is not the most important instruction when focusing on reducing sodium intake.

Correct Answer: C

Rationale: Administering a diuretic like furosemide is the priority intervention for a client with cirrhosis, ascites, and peripheral edema. Furosemide helps reduce fluid overload by promoting diuresis. Elevating the legs may provide some symptomatic relief but does not address the underlying issue of fluid overload. Restricting fluids is not appropriate initially as the client needs proper hydration while managing fluid balance. Monitoring intake and output is important but not the first action to address the immediate fluid overload in this client.

Correct Answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.
