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 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.

A. "Have you been experiencing any difficulty in achieving an erection?" B. "Have you noticed any unusual discharge from your penis?" C. "Has there been a decrease in the force of your urinary stream?" D. "Has there been any change in your sex life in the past year?"

Correct Answer is C

Explanation

Choice A rationale: This question is not relevant to BPH, as erectile dysfunction is not a common complication of this condition. Erectile dysfunction can have other causes, such as cardiovascular disease, diabetes, medications, psychological factors, or aging.

Choice B rationale: This question is not relevant to BPH, as penile discharge is not a symptom of this condition. Penile discharge can indicate an infection, such as sexually transmitted diseases, urinary tract infections, or prostatitis.

Choice C rationale: BPH is a condition that causes enlargement of the prostate gland, which can obstruct the flow of urine and cause symptoms such as difficulty in starting or stopping urination, weak or intermittent stream, dribbling, and incomplete bladder emptying. Asking about the force of the urinary stream can help assess the severity of BPH and the need for treatment.

Choice D rationale: This question is not relevant to BPH, as sexual function is not directly affected by this condition. However, some men with BPH may experience reduced libido or satisfaction due to urinary symptoms or psychological distress.
