Depression

Opiate overdose

The Correct Answer is D

A. Depression:

CNS stimulants are generally not indicated for depression. In fact, they can exacerbate symptoms and are not considered a first-line treatment for depressive disorders.

B. Opiate overdose:

CNS stimulants are not indicated for treating opiate overdose. In cases of overdose, other medications like naloxone are commonly used to reverse the effects of opioids.

C. Poor appetite:

CNS stimulants may be used to increase alertness and decrease fatigue, but they are not typically prescribed to address poor appetite. Appetite stimulation is often managed through other approaches.

Correct Answer is ["100"]

Explanation

To calculate the infusion rate for gentamicin, the nurse needs to use the following formula:

infusion rate (mL/h) = volume (mL) x 60 / time (min).

Plugging in the given values, we get: infusion rate (mL/h) = 50 x 60 / 30 = 100.

Therefore, the nurse would program the electronic infusion pump at 100 mL/h.
