Question 1 of 5
A nurse is preparing to administer lorazepam 2 mg IV for a client with acute anxiety. The available concentration is 4 mg/mL. How many mL should the nurse administer?
Correct Answer: 0.5
Rationale: The correct answer is 0.5 mL.
To calculate this, we use the formula: desired dose (2 mg) divided by available dose (4 mg/mL) = volume to be administered (X mL). So, 2 mg / 4 mg/mL = X mL. Solving for X gives us X = 0.5 mL. This is the amount the nurse should administer to ensure the client receives the correct dose of lorazepam.
Incorrect answers:
A: 1 mL - This is incorrect because it would result in administering twice the desired dose.
B: 2 mL - This is incorrect because it would result in administering four times the desired dose.
C: 0.25 mL - This is incorrect because it would result in administering half the desired dose.
D: 0.75 mL - This is incorrect because it would result in administering 1.5 times the desired dose.
E: 0.1 mL - This is incorrect because it is too
