Question

a) 1.5 mL
b) 1.4 mL
c) 1.6 mL
d) 1.7 mL

Answer 1

To administer 7.5 mg of Diazepam for alcohol withdrawal, the nurse should administer 1.5 mL (round to the nearest tenth) of Diazepam injection. The correct option is option a).

Step-by-step explanation:

To calculate the mL of Diazepam the nurse should administer, we can use the formula:

C₁V₁ = C₂V₂

In this case, C₁ = 5 mg/ml (concentration of Diazepam injection), V₂ = 7.5 mg (desired dose), and C₂ is unknown.

Let's rearrange the formula to solve for V₁:

V₁ = (C₂V₂) / C₁ = (7.5 mg) / (5 mg/ml) = 1.5 ml

Therefore, the nurse should administer 1.5 mL (round to the nearest tenth) of Diazepam injection to the client.
