A nurse is reviewing the medication record of a client who has hypertension. Which of the following medications should the nurse administer to lower the client's blood pressure?

A. "Limit potassium-containing foods in your diet." Long-term prednisone use can lead to hypokalemia (low potassium levels) due to its mineralocorticoid effects, which increase potassium excretion. Clients on chronic corticosteroid therapy may actually need to consume potassium-rich foods to help maintain electrolyte balance, rather than restricting them.

B. "Withhold prednisone for 48 hours prior to receiving contrast dye." There is no general recommendation to withhold prednisone before contrast dye administration. However, clients on long-term steroid therapy may require stress-dose steroids if undergoing procedures that could trigger an adrenal crisis. Withholding prednisone without provider guidance could increase the risk of adrenal insufficiency.

C. "Measure your blood glucose levels periodically." Prednisone can cause hyperglycemia by increasing insulin resistance and promoting gluconeogenesis. Clients, especially those with diabetes or at risk for metabolic syndrome, should monitor blood glucose levels regularly to detect potential steroid-induced diabetes. Adjustments in diet or medication may be needed based on blood glucose trends.

D. "Take prednisone on an empty stomach." Taking prednisone on an empty stomach can increase the risk of gastrointestinal irritation, ulcers, and gastritis. It should be taken with food or milk to help reduce stomach irritation and minimize gastrointestinal side effects. Clients should be advised to follow this guideline to prevent discomfort and potential complications.

• Shortness of breath. The client is experiencing respiratory distress, which could indicate a severe allergic reaction (anaphylaxis). Immediate intervention is needed to prevent airway compromise and respiratory failure.
• Intercostal retractions. Retractions occur when breathing is labored, suggesting airway obstruction or bronchoconstriction. This is a sign of worsening respiratory distress, requiring urgent medical attention.
• Wheezing auscultated throughout lung fields. Wheezing suggests bronchospasm, which is common in anaphylaxis and asthma attacks. The presence of diffuse wheezing indicates that the airways are narrowing, making breathing more difficult.
• Diffuse, raised rash present on trunk. A new-onset rash following antibiotic administration raises suspicion for anaphylaxis or a severe allergic reaction. Immediate treatment with antihistamines and corticosteroids may be required.
• Respiratory rate 30/min. The increased respiratory rate indicates that the client is compensating for airway constriction and hypoxia. This is an early warning sign of impending respiratory failure if not treated promptly.
• Blood pressure 90/55 mmHg. The drop in blood pressure suggests anaphylactic shock, where vasodilation and fluid leakage from capillaries lead to hypotension. Immediate administration of epinephrine is necessary to prevent cardiovascular collapse.
• Oxygen saturation 91% on room air. A decrease in oxygen saturation indicates impaired gas exchange, likely due to airway swelling and bronchospasm. Supplemental oxygen therapy should be provided to prevent further desaturation.
