A male client tells the nurse that he obtained sildenafil without a prescription over the internet, and asks the nurse if it is safe to take. In addition to advising the client to obtain medical evaluation, it is important that the nurse immediately determines if he takes which other type of medication?

A. Hold one nostril closed while spraying the other nostril: Closing one nostril while administering the spray ensures the medication is delivered more effectively into the nasal passages, allowing for better absorption and symptom control by maximizing the contact of the medication with the nasal mucosa.

B. Use the inhaler when first awakening in the morning: The specific timing of intranasal corticosteroid use may vary depending on the healthcare provider's instructions and the client's symptom pattern. While morning use can be beneficial due to peak allergy symptoms, it is not the most critical technique instruction. Proper administration ensures better drug efficacy regardless of timing.

C. Avoid shaking the inhaler immediately before using: Some nasal sprays, especially suspensions, require shaking to evenly distribute the medication. Advising not to shake could lead to inconsistent dosing and reduced effectiveness, depending on the specific medication.

D. Angle the tip of the inhaler upward while spraying: The inhaler tip should be angled slightly outward toward the ear, not straight upward, to target the correct nasal structures. Spraying directly upward could lead to discomfort or less effective drug delivery.

A. Serum liver enzymes: Statins are metabolized in the liver and can cause hepatotoxicity. Baseline liver enzyme levels, such as ALT and AST, should be reviewed before starting statin therapy to ensure the liver is functioning properly and to monitor for potential adverse effects.

B. Serum electrolytes: Electrolytes are important for overall health, but they are not specifically impacted by statin therapy. Reviewing electrolyte levels is not a priority before initiating statins unless other conditions warrant it.

C. Complete blood count: A complete blood count (CBC) provides valuable information about infection or anemia, but it is not directly related to the safety or monitoring of statin medications.

D. Capillary blood glucose: Statins have been associated with a slight risk of elevated blood glucose over long-term use, but an initial capillary blood glucose reading is not required prior to starting therapy. Liver function assessment is the priority.
