A client is brought to the emergency center for fluid replacement after running a marathon, and the healthcare provider prescribes a 500 mL bolus of 0.9% normal saline to be administered over 4 hours. The infusion set delivers 10 gtt/mL, so the nurse should regulate the infusion to deliver how many gtt/minute? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Correct Answer: 21

Rationale: To find the answer, we can use the following formula: (gtt/min) = (mL/hour) x (gtt/mL) / 60. Substituting the given values, we get: (gtt/min) = (500 / 4) x (10) / 60. Simplifying, we get: (gtt/min) = 125 x 10 / 60. (gtt/min) = 20.833. (rounded gtt/min) = 21. Therefore, the nurse should regulate the infusion to deliver 21 gtt/minute of 0.9% normal saline.

A patient with deep vein thrombosis (DVT) is receiving a continuous infusion of Heparin Sodium 20,000 Units in 5% Dextrose Injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)

Correct Answer: 1200

Rationale: To find the answer, we can use the following formula: (units of heparin) = (mL/hour) x (hours) x (units per mL). Substituting the given values, we get: (units of heparin) = (25) x (12) x (20,000 / 500). Simplifying, we get: (units of heparin) = (25) x (12) x (40). (units of heparin) = 1200. Therefore, the client should receive 1200 units of heparin in 12 hours.

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.

The healthcare provider prescribes ceftazidime 30 mg/kg/day for an infant weighing 3,500 grams. What dose should the nurse administer daily to this infant? (Enter numeric value only.)

Correct Answer: 105

Rationale: To find the answer, we can use the following steps: Convert the infant's weight from grams to kilograms by dividing by 1000. Multiply the weight in kilograms by the dosage in mg/kg/day. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (3,500) / (1000) = 3.5 kg. (dose in mg/day) = (30) x (3.5) = 105 mg/day. (rounded dose in mg/day) = 105 mg. Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.

The healthcare provider prescribes liraglutide 1.2 mg subcutaneously daily for a client with type 2 diabetes mellitus. The liraglutide Pen contains 18 mg of liraglutide and will deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. When teaching the client about the use of the liraglutide Pen, how many doses should the nurse tell the client is available in each Pen? (Enter the numerical value only.)

Correct Answer: 15

Rationale: To find the answer, we can use the following formula: (number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed). Substituting the given values, we get: (number of doses) = (18) / (1.2). Simplifying, we get: (number of doses) = 15. Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.

A child is to receive vancomycin 40 mg/kg intravenously one hour before a scheduled procedure. The child weighs 44 pounds. How many mg of the medication should the nurse administer? (Enter numeric value only.)

Correct Answer: 800

Rationale: To find the answer, we can use the following steps: Convert the child's weight from pounds to kilograms by dividing by 2.2. Multiply the weight in kilograms by the dosage in mg/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (44) / (2.2) = 20. (dose in mg) = (40) x (20) = 800. (rounded dose in mg) = 800. Therefore, the nurse should administer 800 mg of vancomycin to the child.
