The health care provider prescribes the antibiotic tetracycline HCl for an adult client who arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?

Choice A reason: This is the correct action for the nurse to take. Risedronate is a bisphosphonate that is used to treat osteoporosis by inhibiting bone resorption. It should be taken with a full glass of water at least 30 minutes before the first food or drink of the day, as food and beverages can reduce its absorption and effectiveness. Milk and other dairy products are especially problematic, as they contain calcium, which can bind to risedronate and prevent it from reaching the bone.

Choice B reason: This is not a correct action for the nurse to take. Assigning a UAP to bring the client a glass of low fat milk is not appropriate, as it contradicts the instruction to take risedronate with water only. Low fat milk still contains calcium, which can interfere with risedronate absorption. The nurse should educate the client and the UAP about the proper administration of risedronate and the importance of avoiding food and beverages for at least 30 minutes after taking the medication.

Choice C reason: This is not a correct action for the nurse to take. Consulting with a pharmacist about scheduling the dose one hour after the client eats is not necessary, as risedronate should be taken before the first food or drink of the day, not after. Taking risedronate one hour after eating may not ensure adequate absorption and efficacy, as food and beverages can remain in the stomach for longer periods of time. The nurse should follow the prescribed schedule and the manufacturer's guidelines for risedronate administration.

Choice D reason: This is not a correct action for the nurse to take. Withholding the medication until the client's breakfast tray is available on the unit is not advisable, as it may delay the treatment of osteoporosis and increase the risk of fractures. Risedronate should be taken as soon as possible after waking up, before the first food or drink of the day, to maximize its absorption and effectiveness. The nurse should not postpone the medication administration without consulting the healthcare provider.

Choice A reason: This is not the correct time to collect the peak and trough levels. The peak level should be measured after the completion of the IV dose, not during the administration. The trough level should be measured just before the next administration, not 30 minutes before.

Choice B reason: This is the correct time to collect the peak and trough levels. The peak level should be measured one hour after the completion of the IV dose, when the concentration of the medication is highest in the blood. The trough level should be measured one hour before the next administration, when the concentration of the medication is lowest in the blood.

Choice C reason: This is not the correct time to collect the peak and trough levels. The peak level should be measured one hour after the completion of the IV dose, not two hours after. The trough level should be measured one hour before the next administration, not two hours before.

Choice D reason: This is not the correct time to collect the peak and trough levels. The peak level should be measured one hour after the completion of the IV dose, not immediately after. The trough level should be measured one hour before the next administration, not 30 minutes before.
