Question 1 of 5
During a home visit, the nurse learns that a client is taking calcium polycarbophil, an over the counter laxative. A single tablet contains 625 mg and the daily maximum dosage is 5 grams in divided doses. How many tablets could the client safely take in one day?(Enter the numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 8
Rationale: The correct answer is 8 tablets.
To find the answer, we can use the following steps: Convert the daily maximum dosage from grams to milligrams by multiplying by 1000. Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet. Round the result to the nearest whole number. Using these steps, we get: (daily maximum dosage in mg) = (5) x (1000) = 5000 mg. (number of tablets) = (5000) / (625) = 8 tablets. (rounded number of tablets) = 8.
Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.
Question 2 of 5
A patient receives a prescription for warfarin 2 mg IM daily. The pharmacy delivers a vial labeled, warfarin 5 mg/single-use vial. The instructions read, reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL. How many mL should the nurse administer?(Enter the numerical value only.)
Correct Answer: 1
Rationale: First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin. Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula: Amount of solution = amount of water + amount of warfarin. Substituting the given values, we get: Amount of solution = 2.7 + 5 = 7.7 mL. Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula: mL of solution = mg of warfarin / concentration of warfarin. Substituting the given values, we get: mL of solution = 2 / 2 = 1 mL.
Therefore, the nurse should administer 1 mL of solution to the patient.
Question 3 of 5
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.
Question 4 of 5
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.
Question 5 of 5
A patient is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. How many mL/hour should the nurse program the infusion pump?(Enter numerical value only.)
Correct Answer: 250
Rationale:
To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (500 / 120) x 60. Simplifying, we get: (mL/hour) = 4.167 x 60. (mL/hour) = 250.
Therefore, the nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS to the patient.
