For each instruction, click to indicate whether the instructions given by the nurse are indicated or contraindicated to prepare for the client's first dose of captopril.

choice A, Drawing the peak level two hours after the IV dose is too late to capture the drug's highest serum concentration. Similarly, drawing the trough two hours before the next dose does not reflect the lowest drug level accurately.
Choice B,Drawing the peak level one hour after completion of the IV dose ensures an accurate measurement of the highest serum concentration, as vancomycin typically peaks within this time frame. Drawing the trough one hour before the next dose ensures the lowest concentration of the drug is measured, providing precise therapeutic monitoring.

Choice C is incorrect because drawing blood 30 minutes into the IV dose would not allow the full dose to circulate and reach peak levels in the bloodstream.

Choice D.Drawing the peak level immediately after the completion of the IV dose is too early, as the drug needs time to distribute in the bloodstream and reach its highest concentration. While drawing the trough 30 minutes before the next dose is appropriate, the incorrect timing of the peak makes this option unsuitable.

Choice A rationale: Tetracycline should generally be taken on an empty stomach, as certain food and beverages, including orange juice, can interfere with its absorption. The nurse should instruct the client to take tetracycline with water and on an empty stomach unless otherwise specified by the healthcare provider.

Choice B rationale: Tetracycline is an antibiotic that can make the skin more sensitive to sunlight, leading to an increased risk of sunburn and photosensitivity reactions. To prevent these adverse effects, the nurse should instruct the client to protect their skin from sunlight while taking the medication. This includes using sunscreen, wearing protective clothing, and avoiding prolonged sun exposure. It is essential to educate the client about this potential side effect to ensure their safety and minimize skin reactions during treatment.

Choice C rationale: Tetracycline does not require routine monitoring of serum drug levels. It is an antibiotic with a well-established dosing regimen, and monitoring drug levels is not necessary for its safe and effective use.

Choice D rationale: While taking tetracycline with milk or antacids may help reduce GI irritation, it can also interfere with the absorption of the medication. Therefore, it is generally recommended to take tetracycline with water and on an empty stomach to ensure optimal absorption and effectiveness.
