A nurse is administering a powdered medication to a client.
Which of the following actions should the nurse take first?
Document that the medication was administered.
Mix the medication at the client's bedside.
Check the client for allergies.
Determine the client's response to the medication.
The Correct Answer is C
Choice A rationale
Documenting the medication administration is important but should be done after administering the medication. Documentation ensures proper tracking and accountability but does
not address immediate patient safety concerns like checking for allergies.
Choice B rationale
Mixing the medication at the client's bedside may ensure that the medication is prepared correctly and the client receives it promptly, but it doesn't address the critical step of
ensuring the client's safety by checking for allergies first.
Choice C rationale
Checking the client for allergies is crucial before administering any medication, including powdered forms. Allergic reactions can be severe or life-threatening, so it’s essential to
ensure that the client isn’t allergic to the medication. This step ensures the safety and well-being of the client and prevents potential adverse reactions.
Choice D rationale
Determining the client's response to the medication is important for assessing the medication's effectiveness and identifying any adverse reactions, but it occurs after administration.
Checking for allergies precedes all these steps to prevent any initial harm.

Correct Answer is C
Explanation
Choice A rationale
Including toilet paper with the collected urine can contaminate the sample and affect the accuracy of the test results.
Choice B rationale
The first void at the start of the collection period should be discarded to ensure that only urine produced during the 24-hour period is collected.
Choice C rationale
Refrigerating the urine during the collection period helps preserve the sample and prevent bacterial growth, which could alter the test results.
Choice D rationale
The last void at the end of the collection period should be included to ensure that the full 24-hour period is accounted for in the collection.
Correct Answer is C
Explanation
Choice A rationale
Toxic levels refer to concentrations of a medication that are high enough to cause harmful effects or poisoning. This is not related to the lowest serum concentration.
Choice B rationale
Peak levels are the highest concentration of a medication in the bloodstream after administration. This occurs after the drug is absorbed and distributed.
Choice C rationale
Trough levels occur when the medication is at its lowest concentration in the bloodstream, typically just before the next dose is due. Monitoring trough levels helps ensure therapeutic effectiveness while avoiding toxicity.
Choice D rationale
Half-life refers to the time it takes for the concentration of a drug in the bloodstream to decrease by half. It is not directly related to the lowest serum concentration at a specific point in time.
