Question 1

A client is prescribed metoprolol (Lopressor) 50 mg oral twice daily. The heart rate is 48 bpm before administration. What should the practical nurse do?

Accepted Answer

Hold the medication, document the heart rate, and notify the physician

Answer

Metoprolol is a beta-blocker that slows heart rate. A pre-dose rate of 48 bpm (bradycardia) is a reason to hold the medication and notify the physician.

Question 2

A client's INR result is 4.8 and they are prescribed warfarin. What should the practical nurse do?

Accepted Answer

Hold the warfarin dose and notify the physician with the INR result

Answer

INR 4.8 is supratherapeutic (therapeutic range is typically 2.0-3.0). Warfarin must be held and the physician notified.

Question 3

A client is to receive amoxicillin (Amoxil) 500 mg. Available is amoxicillin 250 mg/5 mL oral suspension. How many mL should be administered?

Accepted Answer

10 mL

Answer

500 mg divided by 250 mg multiplied by 5 mL = 10 mL.

Question 4

A client receiving IV vancomycin develops diffuse flushing, erythema, and pruritus over the face and upper body during the infusion. No dyspnea or hypotension is noted. What should the practical nurse do?

Accepted Answer

Slow the infusion rate and notify the physician, consistent with Red Man Syndrome

Answer

Diffuse flushing, erythema, and pruritus during vancomycin without systemic signs is Red Man Syndrome, a rate-related reaction managed by slowing the infusion.

Question 5

A client is prescribed insulin glargine (Lantus) 20 units at bedtime. Which practice is incorrect?

Accepted Answer

Mixing glargine with regular insulin in the same syringe

Answer

Insulin glargine (Lantus) must NEVER be mixed with other insulins as mixing alters its pH and destroys the long-acting profile.
