A client began taking hydrochlorothiazide 1 week ago and is reporting occasional dizziness when standing up quickly from sitting or lying. What is the nurse's best action?
Arrange for the client's potassium levels to be assessed as soon as possible
Teach the client about the blood pressure effects of the medication and relevant safety measures.
Educate the client about the need for bed rest until the body adjusts to the new medication.
Tell the client to withhold the medication until the client can be assessed by the primary health care provider.
The Correct Answer is B
A. While assessing potassium levels is important for clients on diuretics, the immediate concern is the client's dizziness, which indicates a potential issue with blood pressure.
B. Teaching the client about the potential for orthostatic hypotension caused by hydrochlorothiazide and instructing them on safety measures (e.g., standing up slowly) is crucial to prevent falls and address the dizziness.
C. Bed rest is not necessary; the client should be educated about managing dizziness instead.
D. Withholding the medication is not warranted unless directed by a healthcare provider; the focus should be on safety education.

Correct Answer is B
Explanation
A. A drug that binds tightly to protein is typically released slowly, not quickly, as it remains bound in circulation.
B. Tight binding to proteins usually results in a prolonged duration of action since the drug is released gradually into the bloodstream, leading to sustained therapeutic effects.
C. Drugs that bind tightly to protein are generally not excreted quickly; they remain in circulation longer due to the binding.
D. While toxicity can occur with any drug, tight protein binding does not inherently lead to toxicity; it primarily affects the pharmacokinetics of the drug.
Correct Answer is B
Explanation
A. Administer the insulin to the client is incorrect as the nurse should first verify the dosage for safety before administration.
B. Check the dosage with another nurse is correct because double-checking the insulin dosage with another licensed nurse is a critical safety step to prevent medication errors.
C. Check the client's blood sugar again is incorrect; while monitoring blood sugar is important, it is not the immediate next action after preparing the insulin.
D. Ensure a meal tray is available is incorrect; although the client should have a meal ready after insulin administration, the priority action before administering the medication is to confirm the dosage.
