Nursing Elites

1. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?

• A. Neutralizes stomach acid
• B. Decreases gastric acid secretion
• C. Covers the ulcer site and protects it from acid
• D. Improves gastric motility

Correct answer: C

Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.

2. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin?

• A. Complete blood count (CBC)
• B. Activated partial thromboplastin time (aPTT)
• C. Prothrombin time (PT)
• D. International normalized ratio (INR)

Correct answer: B

Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). This test is used to monitor the effectiveness of heparin therapy. A complete blood count (CBC) (choice A) is not specific for monitoring heparin therapy. Prothrombin time (PT) (choice C) and International normalized ratio (INR) (choice D) are more commonly used to monitor warfarin therapy, not heparin.

3. The healthcare provider prescribes Cytovene 375 mg every 12 hours to infuse over 90 minutes. The pharmacy delivers Cytovene 375 mg in a 150 mL IV bag. How many ml/hour should the nurse program the infusion pump?

• A. 50 ml/hour.
• B. 75 ml/hour.
• C. 100 ml/hour.
• D. 125 ml/hour.

Correct answer: C

Rationale: To infuse 150 mL over 90 minutes, the pump should be set to 100 ml/hour (150 mL / 1.5 hours). This rate ensures that the medication is delivered at the proper rate as prescribed. Choices A, B, and D are incorrect because they do not reflect the correct calculation based on the volume of the IV bag and the infusion duration provided in the question.

4. A client with asthma is prescribed a metered-dose inhaler (MDI) with albuterol. Which instruction is essential for the nurse to provide?

• A. Use the inhaler only before bedtime
• B. Shake the inhaler well before use
• C. Exhale fully before inhaling the medication
• D. Take two puffs every hour

Correct answer: B

Rationale: The correct answer is to 'Shake the inhaler well before use.' This instruction is crucial as shaking the inhaler ensures the proper mixing of the medication, which is essential for its effective delivery. Option A is incorrect because using the inhaler only before bedtime may not provide adequate relief during the day. Option C is incorrect as exhaling fully is a good practice but not the most essential instruction. Option D is incorrect as taking two puffs every hour may exceed the recommended dosage and lead to adverse effects.

5. A child has developed a diaper rash, and the parents are using zinc oxide to treat it. What does the nurse suggest to aid in the removal of the zinc oxide?

• A. Mild soap and water
• B. A cotton ball
• C. Mineral oil
• D. Alcohol swabs

Correct answer: C

Rationale: To completely remove ointment, especially zinc oxide, mineral oil should be used. Mineral oil helps in gently breaking down and lifting the ointment without causing irritation. Mild soap and water (Choice A) may not be effective in completely removing zinc oxide. A cotton ball (Choice B) may not provide the necessary lubrication to aid in the removal process. Alcohol swabs (Choice D) can be harsh on the skin and are not recommended for this purpose.
