Question 1 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?

A. Cover your skin before going outside.B. Monitor skin for excessive bruising.C. Limit intake of high-potassium foods.D. Replace salt with a salt substitute.

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 2 of 5

On admission, the healthcare provider prescribes a broad spectrum antibiotic for a client with a gram-negative infection. Before administering the first dose, it is most important for the nurse to implement which prescription?

A. Monitor for signs of sodium and fluid retention.B. Wound and blood specimens for culture and sensitivity.C. Complete blood count and serum electrolytes.D. Irrigation and topical antibiotic application to wound area.

Correct Answer: B

Rationale: Obtaining cultures (
B) before antibiotics identifies the specific bacteria and ensures effective treatment. Sodium/fluid monitoring (
A) is unrelated to antibiotics. Blood count/electrolytes (
C) don’t guide initial therapy.
Topical antibiotics (
D) are secondary.

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

A female client who is a vegetarian has a new prescription for warfarin. The client states she eats leafy green vegetables every day. How should the nurse respond?

A. Suggest that the client replace the leafy vegetables with a protein source such as nuts or beans.B. Commend the client for her healthy lifestyle and encourage her to continue her current diet habits.C. Advise the client that the healthcare provider needs to be made aware of her current diet.D. Confirm that her diet choices will help the medication be more effective in preventing blood clots.

Correct Answer: C

Rationale: Leafy greens, high in vitamin K, reduce warfarin’s anticoagulant effect (
C) (matches 55-Q46). Informing the provider ensures dose adjustment. Substituting vegetables (
A) is unnecessary. Praising (
B) or claiming enhanced efficacy (
D) ignores the interaction.

Question 5 of 5

A client is receiving intravenous (IV) vancomycin and the nurse plans to draw blood for a peak and trough to determine the serum level of the drug. Which collection times provide the best determination of these levels?

A. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.B. One hour after completion of the IV dose and one hour before the next administration of the medication.C. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration of the medication.D. Two hours after completion of the IV dose and two hours before the next administration of the medication.

Correct Answer: A

Rationale: Vancomycin peak is typically drawn 1 hour post-infusion, trough 30-60 minutes pre-dose (matches 55-Q30/38, answer
B). Option A may overestimate peak but is provided as correct. Other timings (C,
D) miss accurate concentrations.
Note: Confirm if B is intended.
