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.

1.4

1.5

0.7

Answer and Explanation

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: This is a sign of worsening diabetes insipidus.

Choice B rationale: This shows signs of overhydration, as urine output is high and specific gravity is high.

Choice C rationale: This is a sign of worsening diabetes insipidus.

Choice D rationale: Vasopressin is a hormone that helps the kidneys retain water and concentrate urine. Diabetes insipidus is a condition where the body does not produce enough vasopressin or does not respond to it, resulting in excessive urination and diluted urine. The goal of vasopressin therapy is to reduce urine output and increase urine concentration, which indicates that the kidneys are functioning properly and the body is hydrated.

A. Localization of pain B. Decorticate posturing C. Decerebrate posturing D. Flexion withdrawal

Correct Answer is B

Explanation

Choice A rationale: Localization of pain refers to the ability of an individual to pinpoint the exact location of pain, which is different from the described response.

Choice B rationale: Decorticate posturing involves the arms flexing inward toward the body, which is consistent with the observed response to nail bed pressure.

Choice C rationale: Decerebrate posturing involves extension and outward rotation of the arms, which is different from the described response.

Choice D rationale: Flexion withdrawal typically involves pulling away from a painful stimulus, which differs from the specific response observed in the scenario.
