A patient diagnosed with hyperaldosteronism presents with symptoms of a blood pressure of 220/135 mmHg and a potassium level of 3.1 mEq/L. Which of the following interventions should the nurse prioritize?

Choice A rationale Scheduling a CT scan is a diagnostic step used to identify adrenal adenomas or hyperplasia, which are common causes of primary hyperaldosteronism. However, in an acute presentation with a blood pressure of 220/135 mmHg, diagnostic imaging is not the immediate priority. The patient is experiencing a hypertensive crisis, which requires urgent physiological stabilization. While imaging is necessary for long-term treatment planning, the nurse must first address the life-threatening hemodynamic instability and electrolyte imbalances to prevent end-organ damage. Choice B rationale A low-sodium diet is a long-term management strategy for hyperaldosteronism to help control fluid retention and hypertension. However, in the presence of a hypertensive emergency, dietary modifications are insufficient and too slow to be effective. The patient requires immediate pharmacological intervention to lower blood pressure and prevent a cerebrovascular accident or myocardial infarction. Initial nursing actions must focus on acute interventions that produce rapid physiological changes rather than lifestyle or dietary adjustments that take days to manifest. Choice C rationale Monitoring for signs of fluid overload is the priority because aldosterone causes the kidneys to retain sodium and water while excreting potassium. Excess aldosterone leads to an expanded intravascular volume, contributing to the severe hypertension of 220/135 mmHg. The nurse must assess for peripheral edema, jugular venous distention, and pulmonary crackles. Managing volume status is critical to preventing heart failure and further escalation of the hypertensive crisis, making it the most vital assessment for a patient in this state. Choice D rationale Administering potassium supplements is necessary to correct the hypokalemia of 3.1 mEq/L, as the normal range is 3.5 to 5.0 mEq/L. However, potassium must be replaced with extreme caution in the setting of severe hypertension and potential renal impairment. While correcting the heart's electrical stability is important, the immediate threat to the patient's life is the extremely high blood pressure. Monitoring the systemic effects of the fluid and electrolyte imbalance takes precedence to guide safe administration of intravenous medications. .
