The nurse is caring for a client with a new diagnosis of hyperthyroidism. Which intervention should the nurse prioritize?

Choice A reason: Monitoring daily urine output assesses kidney function and fluid balance, as urine volume reflects hydration and electrolyte homeostasis. Inadequate output signals dehydration or renal issues, allowing timely intervention to maintain fluid and electrolyte balance, making it the most effective nursing action.

Choice B reason: Salt tablets after exercise replace sodium lost in sweat but are not a universal intervention for fluid and electrolyte balance. They risk hypernatremia if overused. Monitoring urine output is more comprehensive, as it directly evaluates fluid status across various clinical scenarios.

Choice C reason: Reviewing food labels for sodium content helps manage dietary intake but is indirect and patient-dependent. Urine output monitoring provides objective data on fluid and electrolyte status, enabling timely adjustments in therapy, making it a more immediate and reliable intervention.

Choice D reason: Drinking water when thirsty supports hydration but relies on subjective thirst, which may be impaired in certain conditions. Monitoring urine output objectively assesses fluid balance, detecting imbalances early, making it a more proactive and precise intervention than thirst-driven hydration.

Choice A reason: Rebound tenderness in the right lower quadrant (McBurney’s point) is a hallmark of appendicitis, indicating peritoneal irritation from an inflamed appendix. This localized pain, elicited on palpation release, is highly specific, guiding urgent surgical evaluation to prevent rupture and peritonitis.

Choice B reason: Diffuse abdominal pain is nonspecific and occurs in various conditions, not uniquely appendicitis, which typically presents with localized right lower quadrant pain. Rebound tenderness is more diagnostic, as it directly reflects appendiceal inflammation, making it the priority finding.

Choice C reason: Decreased bowel sounds may occur in appendicitis due to ileus but are nonspecific, seen in other abdominal conditions. Rebound tenderness is more indicative, as it localizes to the appendix, confirming peritoneal irritation, critical for diagnosing acute appendicitis.

Choice D reason: Elevated blood pressure is not specific to appendicitis and may reflect pain or stress. Rebound tenderness directly indicates appendiceal inflammation, making it the most reliable finding, as it guides diagnosis and urgent intervention to prevent complications like perforation.
