Question 1 of 5
A nurse is preparing to administer diphenhydramine 30 mg IM stat to a client who is having an allergic reaction. Available is diphenhydramine 50 mg/1 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: The correct answer is B: 0.6 mL.
To calculate the amount of diphenhydramine to administer, use the formula: Desired dose (30 mg) / Available dose (50 mg) = X mL. So, 30 mg / 50 mg = 0.6 mL. This is rounded to the nearest tenth.
Choice A is incorrect as it is less than the correct answer.
Choices C, D, and the remaining options are incorrect as they are greater than the correct answer. The key is to accurately calculate the dosage based on the available concentration to ensure the correct amount is administered.
