Which blood level is assessed to determine the amount of circulating medication in a patient?.
Trough.
Drug.
Peak.
Therapeutic.
The Correct Answer is C
Choice A rationale:
Trough levels are the lowest concentration in the patient’s bloodstream, hence they are not the best indicator of the amount of circulating medication.
Choice B rationale:
The term ‘Drug’ is too general and does not specifically refer to the amount of medication in the patient’s bloodstream.
Choice C rationale:
Peak levels are the highest concentration of a drug in the patient’s bloodstream after administration. This is when the amount of the medication in the body is likely to be highest.
Choice D rationale:
Therapeutic levels refer to the range in which a drug is expected to be effective without causing any serious problems to the patient. It does not directly indicate the amount of circulating medication.

Correct Answer is A
Explanation
Choice A rationale:
Using a follow-up rinse with a flavored drink is a common practice when administering oral medication to a preschool child. This helps mask the taste of the medication, making it more palatable for the child.
Choice B rationale:
Placing the capsule or tablet under the tongue (sublingual administration) is not typically recommended for preschool children due to the risk of choking.
Choice C rationale:
Supporting the child’s head and holding the child in the lap can be helpful but is not a specific guideline for administering oral medication.
Choice D rationale:
Using chewable tablets can be an option if the child’s teeth are not loose. However, it’s not a general guideline as not all medications come in chewable form.
Correct Answer is A
Explanation
Choice A rationale:
A decrease in blood pressure is a common side effect when a medication increases urine output, as the reduction in fluid volume can lead to lower blood pressure.
Choice B rationale:
While a decrease in blood pressure might be desired in certain conditions (like hypertension), in this context it is a side effect, not the primary desired effect.
Choice C rationale:
The therapeutic effect of the medication in this case is to increase urine output, not to decrease blood pressure.
