A nurse is preparing to administer metoprolol 10 mg IV bolus to a client for heart rate control. Available is metoprolol injection 2.5 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
Determine the desired dose.
The nurse needs to administer 10 mg of metoprolol.
Calculate the available dose per mL.
The available metoprolol is 2.5 mg/mL.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/mL) = 10 mg / 2.5 mg/mL = 4 mL

Correct Answer is ["83.3"]
Explanation
Convert the patient's weight to kg.
The patient weighs 185 lb.
1 lb is approximately equal to 0.45 kg.
Patient's weight in kg = 185 lb x 0.45 kg/lb = 83.25 kg
Calculate the dose per administration.
The prescribed dose is 1 mg/kg/dose.
Dose per administration = 1 mg/kg/dose x 83.25 kg = 83.25 mg/dose
Round the dose to the nearest tenth.
Dose per administration = 83.3 mg
Correct Answer is ["2"]
Explanation
Determine the dose per administration.
The total daily dose is 2 grams, which is 2000 mg.
The dose is divided into four doses, so the dose per administration is 2000 mg / 4 = 500 mg.
Calculate the number of capsules per administration.
Each capsule contains 250 mg of tetracycline.
Number of capsules = Dose per administration (mg) / Capsule strength (mg) = 500 mg / 250 mg/capsule = 2 capsules.
