When preparing medications for delivery to an assigned patient, the nurse should check each medication for accuracy of drug and dose:

One time.

Two times.

Three times.

Five times.

Answer and Explanation

The Correct Answer is C

Choice A reason: Checking medications only once increases the likelihood of errors. Safe practice requires multiple verification steps.

Choice B reason: While better than a single check, verifying only twice may still miss potential discrepancies in drug or dosage accuracy.

Choice C reason: The three-check system (when retrieving, preparing, and administering medication) minimizes errors, ensuring patient safety through consistent validation at each step.

Choice D reason: Excessive verification may delay administration, reducing practicality without significantly improving safety beyond three checks.

Correct Answer is A

Explanation

Choice A reason: Flow rate is volume divided by time; 250 mL over 4 hours equals 62.5 mL/hr, ensuring safe transfusion pacing to avoid fluid overload or hemolysis.

Choice B reason: 125 mL/hr assumes 250 mL over 2 hours; this doubles the ordered rate, risking circulatory overload and transfusion reactions in a standard protocol.

Choice C reason: 250 mL/hr infuses the unit in 1 hour; this rapid rate exceeds safe limits, potentially causing hypertension or pulmonary edema in vulnerable patients.

Choice D reason: 500 mL/hr is far too fast, implying 250 mL in 30 minutes; this dangerous speed could trigger severe hemolytic reactions or cardiovascular collapse.

A. Consult with the client's health care provider. B. Administer the liquid form of the drug. C. Administer the parenteral form of the drug. D. Crush the tablet before administration.

Correct Answer is A

Explanation

Choice A reason: Consulting ensures safety; not all drugs can be altered, and the provider adjusts the order, preventing errors in bioavailability or efficacy.

Choice B reason: Liquid may work, but without approval, it’s unauthorized; some drugs lack liquid forms, and this bypasses necessary prescriber oversight.

Choice C reason: Parenteral needs an order change; administering without it violates scope, and it’s invasive, escalating care unnecessarily as a first step.

Choice D reason: Crushing alters pharmacokinetics; many tablets (e.g., extended-release) can’t be crushed, and doing so without checking risks toxicity or inefficacy.
