Question 1 of 5
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.
Question 2 of 5
The healthcare provider prescribes an IV bolus of diltiazem 0.25 mg/kg for a client with atrial fibrillation. The client weighs 178 pounds. How many mg should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 20
Rationale: The correct answer is 20 mg.
To find the answer, we can use the following steps: Convert the client'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) = (178) / (2.2) = 80.909 kg. (dose in mg) = (0.25) x (80.909) = 20.227 mg. (rounded dose in mg) = 20 mg.
Therefore, the nurse should administer 20 mg of IV diltiazem to the client.
Question 3 of 5
The nurse plans to provide the next shift with the IV fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)
Correct Answer: 270
Rationale:
To find the answer, we can use the following formula: (remaining volume) = (initial volume) - (infused volume). Substituting the given values, we get: (remaining volume) = (440) - ((85 x 2)). Simplifying, we get: (remaining volume) = (440) - (170). (remaining volume) = 270.
Therefore, the remaining volume to be infused is 270 mL.
Question 4 of 5
The healthcare provider prescribes lamivudine oral solution 150 mg twice daily for a client who is HIV positive. The available bottle contains 240 mL of lamivudine labeled, '10 mg/mL.' How many mL should the nurse administer in a 24 hour period?(Enter numeric value only.)
Correct Answer: 30
Rationale: The correct answer is 30 mL.
To find the answer, we can use the following steps: Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations. Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (total daily dose in mg) = (150) x (2) = 300 mg. (volume to be administered in mL) = (300) / (10) = 30 mL. (rounded volume to be administered in mL) = 30 mL.
Therefore, the nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.
Question 5 of 5
A client receives a prescription for amoxicillin 2 g/clavulanate 125 mg by mouth every 12 hours for 10 days. The medication is available in 1000 mg/62.5 mg extended release tablets. How many tablets should the nurse administer?(Enter numerical value only.)
Correct Answer: 2
Rationale:
To find the answer, we can use the following steps: Calculate the number of tablets needed to provide the prescribed dose of amoxicillin by dividing the dose in mg by the amount of amoxicillin in one tablet. Calculate the number of tablets needed to provide the prescribed dose of clavulanate by dividing the dose in mg by the amount of clavulanate in one tablet. Compare the two numbers and choose the larger one as the number of tablets to be administered. Using these steps, we get: (number of tablets for amoxicillin) = (2000) / (1000) = 2. (number of tablets for clavulanate) = (125) / (62.5) = 2. (number of tablets to be administered) = max(2, 2) = 2.
Therefore, the nurse should administer 2 tablets of amoxicillin/clavulanate to the client.
