A patient with pheochromocytoma
is admitted to the hospital with severe hypertension. Which nursing intervention is the highest priority?
Administering an alpha-adrenergic blocker as prescribed.
Administering intravenous fluids to maintain hydration.
Monitoring blood glucose levels every 4 hours.
Preparing the patient for immediate surgery to remove the tumor.
The Correct Answer is A
Choice A Reason:
Administering an alpha-adrenergic blocker is the highest priority intervention for a patient with pheochromocytoma and severe hypertension. Pheochromocytoma causes excessive secretion of catecholamines, leading to severe hypertension. Alpha-adrenergic blockers help to control blood pressure by blocking the effects of these catecholamines, thereby reducing vasoconstriction and lowering blood pressure. This intervention is crucial to prevent hypertensive crises and associated complications such as stroke or myocardial infarction.
Choice B Reason:
Administering intravenous fluids to maintain hydration is important but not the highest priority. While maintaining hydration is essential, it does not directly address the severe hypertension caused by pheochromocytoma. Intravenous fluids can help support overall patient stability but do not specifically target the underlying cause of the hypertension.
Choice C Reason:
Monitoring blood glucose levels every 4 hours is a necessary intervention, especially since pheochromocytoma can cause hyperglycemia due to increased catecholamine levels. However, this intervention is not the highest priority compared to controlling the severe hypertension, which poses a more immediate threat to the patient’s health.
Choice D Reason:
Preparing the patient for immediate surgery to remove the tumor is a critical step in the long-term management of pheochromocytoma. However, surgery is not typically performed until the patient’s blood pressure is stabilized with medications such as alpha-adrenergic blockers. Therefore, while surgery is essential, it is not the immediate priority in the acute management of severe hypertension.

Correct Answer is A
Explanation
Choice A Reason:
Implementing strict hand hygiene protocols is the most critical intervention to prevent infection in patients with acute lymphoblastic leukemia (ALL). Patients with ALL are highly susceptible to infections due to their compromised immune systems, which result from both the disease and the chemotherapy treatment. Hand hygiene is a fundamental practice in infection control, significantly reducing the transmission of pathogens. Ensuring that all healthcare providers, patients, and visitors adhere to strict hand hygiene protocols can greatly minimize the risk of infections.
Choice B Reason:
Administering prophylactic antibiotics regularly can help prevent infections, but it is not the most critical intervention. Overuse of antibiotics can lead to antibiotic resistance and other complications. While antibiotics are important in managing infections, they should be used judiciously and in conjunction with other infection control measures, such as hand hygiene.
Choice C Reason:
Encouraging the patient to eat a high-protein diet is beneficial for overall health and recovery, but it does not directly prevent infections. A high-protein diet can help maintain muscle mass and support the immune system, but it is not a primary infection control measure.
Choice D Reason:
Limiting the patient’s fluid intake is not relevant to preventing infections in patients with ALL. Adequate hydration is important for overall health and helps in the management of side effects from chemotherapy. Fluid restriction is not a standard intervention for infection prevention in this context.
Correct Answer is D
Explanation
Choice A Reason:
Recommending cleaning the ear with cotton swabs daily is not appropriate for managing otitis externa. Using cotton swabs can further irritate the ear canal, potentially worsening the inflammation and increasing the risk of infection. It is generally advised to avoid inserting anything into the ear canal to prevent damage and irritation.
Choice B Reason:
Advising the patient to use over-the-counter ear drops is not the best initial intervention. While some over-the-counter ear drops may provide temporary relief, they are not as effective as prescription topical antibiotics and corticosteroids in treating the underlying infection and inflammation associated with otitis externa. Proper medical treatment is necessary to ensure effective management of the condition.
Choice C Reason:
Administering oral antibiotics is not typically the first-line treatment for uncomplicated otitis externa. Oral antibiotics are reserved for cases where the infection has spread beyond the ear canal or in patients with risk factors for severe infection. Topical antibiotics and corticosteroids are preferred for their direct action on the affected area and fewer systemic side effects.
Choice D Reason:
Administering topical antibiotics and corticosteroids is the most appropriate initial intervention for otitis externa. Topical treatments effectively target the infection and reduce inflammation, providing relief from symptoms such as pain, itching, and discharge. This approach is supported by clinical guidelines and is considered the standard of care for managing otitis externa.
