The nurse prepares to administer promethazine 35 mg intramuscularly prescribed as needed for a client with cholecystitis who has severe nausea. The ampule label reads that the medication is available in 25 mg/mL. How many milliliters should the nurse administer?
Record your answer using one decimal place.
1
1.4
1.5
0.7
The Correct Answer is B
Choice A rationale: this corresponds with 25 mg which is lower than the prescribed amount.
Choice B rationale: To answer this question, we need to use the formula: volume (mL) = dose (mg) / concentration (mg/mL). We plug in the given values: volume (mL) = 35 mg / 25 mg/mL. We simplify the fraction: volume (mL) = 7/5. We convert the fraction to a
decimal: volume (mL) = 1.4. Therefore, the nurse should administer 1.4 mL of promethazine.
Choice C rationale: this corresponds with 37.5 mg which is too high.
Choice D rationale: this corresponds with 17.5 mg which is too low.

Correct Answer is D
Explanation
Choice A rationale: Activates the rapid response team (RRT) - Status epilepticus is a medical emergency requiring immediate intervention. Activating the rapid response team would ensure a prompt response to the situation.
Choice B rationale: Loosens any restrictive clothing - It is important for patient safety and comfort.
Choice C rationale: Places the client in a lateral position - This is a recommended positioning to prevent aspiration during a seizure.
Choice D rationale: Prepares to administer intravenous valproate acid - Valproic acid is not the first drug during epilepsy hence this action would necessitate immediate intervention.
Correct Answer is C
Explanation
Choice A rationale: Although important to assess for potential kidney injury, addressing hypotension due to potential spinal shock takes priority.
Choice B rationale: Important for determining any neurological deficits, but addressing hypotension is the initial priority.
Choice C rationale: Hypotension indicates potential spinal shock or hemorrhagic shock, and fluid resuscitation is the immediate priority to stabilize the client's blood pressure.
Choice D rationale: While important for assessing cardiac status, addressing hypotension takes precedence to stabilize the client's condition.
