Question 1 of 5
The nurse admits a client with a diagnosis of stage 4 cancer. The client has a prescription to wear a subcutaneous morphine sulfate patch for pain. The client is short of breath and difficult to arouse. While performing a head to toe assessment, the nurse discovers four patches on the client's body. Which action should the nurse take first?
Correct Answer: C
Rationale: Four morphine patches suggest overdose, causing respiratory depression and sedation (matches 55-Q28). Removing patches (
C) stops further absorption. Oxygen (
A) or naloxone (
B) may follow. Blood pressure (
D) is secondary.
Question 2 of 5
A client with heart failure (HF) develops hyperaldosteronism and spironolactone is prescribed. Which instruction should the nurse include in this client's plan of care?
Correct Answer: C
Rationale: Spironolactone, a potassium-sparing diuretic, risks hyperkalemia (matches 55-Q7/17). Limiting high-potassium foods (
C) prevents this. Sun protection (
A) and bruising (
B) are unrelated. Salt substitutes (
D) contain potassium, worsening hyperkalemia.
Question 3 of 5
The nurse receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter Calculation(ans only)al value only.)
Correct Answer: 200
Rationale: Infusion rate: 200 mL / 1 hr = 200 mL/hr (matches 55-Q55). The pump should deliver 200 mL/hr for correct ciprofloxacin administration.
Question 4 of 5
After receiving five doses of filgrastim, the nurse notes that the client's white blood cell count has increased from 2,500/mm3 (2.5 x 109/L) to 5,000/mm3 (5 x 109/L). Which action should the nurse implement?
Correct Answer: B
Rationale: Filgrastim stimulates white blood cell production. An increase to 5,000/mm3 (
B) indicates effectiveness (matches 55-Q11). Neutropenic precautions (
A) are unnecessary. Culture reports (
C) and vital signs (
D) don’t assess filgrastim’s efficacy.
Question 5 of 5
A client has a new prescription for zolpidem, a hypnotic. The client tells the home health nurse that he plans to take a dose of the medication during the day because he is exhausted and needs to take a short afternoon nap prior to an evening activity in his home. Which action should the nurse take?
Correct Answer: A
Rationale: Zolpidem should be taken at bedtime (
A) to avoid daytime drowsiness and fall risk (matches 55-Q4). Fluids (
B) are unrelated. Noon meal dosing (
C) reduces efficacy. Two hours (
D) is insufficient for clearance.
