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

Choice A reason: Furosemide, a loop diuretic, promotes urine output by inhibiting sodium reabsorption in the kidneys, reducing fluid overload in heart failure. Increased urine output indicates effective diuresis, alleviating pulmonary and peripheral edema, making it the primary sign of therapeutic efficacy.

Choice B reason: Elevated blood pressure is not an expected effect of furosemide, which reduces preload and blood volume, often lowering pressure. Effective diuresis is shown by increased urine output, as this directly reflects fluid removal, critical for heart failure management.

Choice C reason: Increased heart rate is not a direct indicator of furosemide efficacy. Diuresis reduces cardiac workload, potentially stabilizing heart rate, but urine output is the primary measure, as it confirms fluid excretion, the medication’s main action in heart failure.

Choice D reason: Weight gain indicates fluid retention, the opposite of furosemide’s goal. Effective diuresis causes weight loss due to fluid excretion. Increased urine output is the key sign, as it directly measures the diuretic’s action in reducing heart failure-related fluid overload.

Choice A reason: Monitoring oxygen saturation is critical in COPD, as oxygen therapy aims to maintain saturation (88–92%) to prevent hypoxia. Pulse oximetry ensures adequate oxygenation, guiding therapy adjustments, making it the priority assessment to prevent respiratory failure and optimize lung function.

Choice B reason: Checking skin color assesses cyanosis but is less precise than oxygen saturation. Pulse oximetry provides objective data on oxygenation in COPD, guiding oxygen therapy, making it the priority over subjective visual assessments, which are secondary to quantitative measures.

Choice C reason: Assessing chest pain is relevant for cardiac issues but not the primary concern in COPD oxygen therapy. Oxygen saturation directly evaluates therapy effectiveness, preventing hypoxia, making it the priority assessment to ensure respiratory stability in chronic lung disease.

Choice D reason: Measuring blood pressure monitors cardiovascular status but is secondary to oxygenation in COPD. Oxygen saturation is critical, as hypoxia exacerbates respiratory distress, requiring immediate assessment to adjust oxygen therapy, making it the priority over hemodynamic evaluations.
