Question 1 of 5
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/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: 0.6 mL
Rationale: The correct answer is 0.6 mL.
To calculate this, divide the dose needed (3 mg) by the concentration of the medication (5 mg/mL). 3 mg / 5 mg/mL = 0.6 mL. This calculation ensures the nurse administers the correct amount of medication. Other choices are incorrect because they do not reflect the accurate calculation based on the given dose and concentration. For example, selecting a higher volume would result in administering more medication than prescribed, potentially leading to overdose, while choosing a lower volume would result in underdosing the patient. The correct answer of 0.6 mL aligns with safe medication administration principles.
