An adult client receives a prescription for diphenhydramine 15 mL by mouth every 12 hours PRN for pruritus. The bottle is labeled, 'diphenhydramine 12.5 mg/5 mL.' What is the total daily dose in mg that the client receives? (Enter numerical value only.)

Correct Answer: 75

Rationale: To find the answer, we can use the following steps: Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL. Multiply the dose in mg per administration by the number of administrations per day. Round the result to the nearest whole number. Using these steps, we get: (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg. (total daily dose in mg) = (37.5) x (2) = 75 mg. (rounded total daily dose in mg) = 75 mg. Therefore, the client receives 75 mg of diphenhydramine per day.

A client receives a prescription for ganciclovir 375 mg intravenously (IV) every 12 hours to infuse over 90 minutes. The pharmacy delivers ganciclovir 375 mg in a 150 mL IV bag. How many mL/hour should the nurse program the infusion pump?(Enter a whole number only.)

Correct Answer: 100

Rationale: The correct answer is 100 mL/hour. To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (150 / 90) x 60. Simplifying, we get: (mL/hour) = 1.667 x 60. (mL/hour) = 100. Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.

A client who weighs 60 kg receives a prescription for dalteparin 200 units/kg subcutaneously once a day for a month. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer?(Enter numerical value. If rounding is required, round to the nearest tenth.)

Correct Answer: 0.5

Rationale: To find the answer, we can use the following steps: Calculate the dose of dalteparin in units by multiplying the weight in kg by the dosage in units/kg. Divide the dose in units by the concentration in units/mL. Round the result to the nearest tenth. Using these steps, we get: (dose in units) = (60) x (200) = 12,000 units. (volume in mL) = (12,000) / (25,000) = 0.48 mL. (rounded volume in mL) = 0.5 mL. Therefore, the nurse should administer 0.5 mL of dalteparin from the vial to the client.

The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)

Correct Answer: 45

Rationale: To find the answer, we can use the following formula: (microdrops/minute) = (mL/hour) x (microdrops/mL) / 60. Substituting the given values, we get: (microdrops/minute) = (45) x (60) / 60. Simplifying, we get: (microdrops/minute) = 45. Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.

Dobutamine hydrochloride 2 mcg/kg/min is prescribed for a client weighing 165 pounds. The solution is mixed with 50 mg of dobutamine in 1,000 mL of D5W. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

Correct Answer: 180

Rationale: To find the answer, we can use the following steps: Convert the client's weight from pounds to kilograms by dividing by 2.2. Calculate the dosage of dobutamine in mg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60. Divide the dosage of dobutamine in mg/hour by the concentration of dobutamine in the solution in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (165) / (2.2) = 75 kg. (dose in mg/hour) = (2) x (75) x (60) = 9000 mcg/hour. (dose in mg/hour) = (9000 x 10^-3) = 9 mg/hour. (volume in mL/hour) = (9) / (50 / 1000) = 180 mL/hour. Therefore, the nurse should set the infusion pump to deliver 180 mL/hour of dobutamine hydrochloride in D5W.

A client receives a prescription for loratadine suspension 10 mg by mouth once a day. The bottle is labeled 'Loratadine for Oral Suspension, USP 5 mg per 5 mL.' How many teaspoons should the nurse instruct the client to take? (Enter numerical value only.)

Correct Answer: 2

Rationale: To find the answer, we can use the following steps: Calculate the volume of loratadine suspension in mL by dividing the dose in mg by the concentration in mg/mL. Convert the volume in mL to teaspoons by multiplying by 0.2. Round the result to the nearest whole number. Using these steps, we get: (volume in mL) = (10) / (5 / 5) = 10 mL. (volume in teaspoons) = (10) x (0.2) = 2 teaspoons. (rounded volume in teaspoons) = 2 teaspoons. Therefore, the nurse should instruct the client to take 2 teaspoons of loratadine suspension.
