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: Providing thickened fluids with a straw is more related to swallowing difficulties and is not the priority in this context.

Choice B rationale: While assessing lung and bowel sounds is important, it's not directly related to offering oral intake after a gastroscopy.

Choice C rationale: Assessing the Hypoglossal nerve and Vestibulocochlear cranial nerve function isn't directly related to offering oral intake post-gastroscopy.

Choice D rationale: Checking the client's Glossopharyngeal nerve and Vagus cranial nerve function is crucial as these nerves play roles in swallowing, taste, and the gag reflex, which are important before allowing oral intake post-gastroscopy.

A. Diabetic ketoacidosis B. Heart failure being treated with furosemide C. Addison disease D. Cushing disease

Correct Answer is C

Explanation

Choice A rationale: Typically associated with potassium depletion rather than elevated levels.

Choice B rationale: Furosemide, a loop diuretic, can cause potassium depletion leading to hypokalemia, but it might also cause transient elevations in potassium levels initially. Choice C rationale: Addison disease can cause hyperkalemia, or high potassium, due to decreased renal excretion of potassium and increased retention of sodium and water.

Choice D rationale: Cushing disease can cause hypokalemia, or low potassium, due to increased renal excretion of potassium and decreased reabsorption of sodium and water.
