A newly ordered medication requires the nurse to make a dosage calculation. Which of the following is the best way to minimize

A. Tachycardia.: A rapid heart rate following administration of an antihypertensive medication is an adverse reaction that may indicate hypotension or reflex sympathetic activation. It requires prompt reporting because it can compromise cardiac function.

B. Lower systolic blood pressure.: A reduction in systolic blood pressure is an expected therapeutic outcome of antihypertensive drugs. As long as the decrease remains within safe limits and the client is asymptomatic, it does not require reporting as an adverse effect.

C. Pleasant mood.: A pleasant or calm mood is not an adverse effect and may indicate improved comfort or reduced stress after blood pressure control. This response requires no intervention and is not clinically concerning.

D. Decreased sense of anxiety.: Lower anxiety levels may reflect the client’s improved physiological stability or reassurance following care. This finding is positive and does not represent a harmful or unintended drug effect.

A. Defer the calculation process to the physician.: It is the nurse’s professional responsibility to calculate and verify medication dosages before administration. Deferring this task to the physician compromises accountability.

B. Call the pharmacy to provide the appropriate calculations.: While pharmacists can assist with complex dosing, the nurse should independently perform and verify dosage calculations. Relying solely on the pharmacy removes a critical safety check within the medication administration process.

C. Consult a current drug book to confirm the new dosage.: Referring to a drug reference is an excellent step for verifying safe dosage ranges and medication information but does not replace the need for independent dose calculation verification.

D. Have another licensed nurse confirm the calculation.: The best way to minimize error is to double-check the dosage with another licensed nurse. Independent verification ensures accuracy, particularly for high-risk medications such as insulin, heparin, and opioids, enhancing overall medication safety.
