Nursing Elites

1. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important instruction the nurse should provide?

• A. Take the medication with a high-fiber meal
• B. Monitor pulse rate daily before taking the medication
• C. Avoid dairy products while on this medication
• D. Discontinue the medication if blurred vision is experienced

Correct answer: B

Rationale: The most important instruction the nurse should provide is to monitor pulse rate daily before taking the medication. Digoxin can lead to bradycardia, so it is crucial to assess the pulse rate before administering the medication. This practice helps ensure that the heart rate is not too low for the safe use of digoxin. Choice A is incorrect as there is no specific requirement to take digoxin with a high-fiber meal. Choice C is also incorrect because there is no need to avoid dairy products while on digoxin. Choice D is incorrect since blurred vision is not a common side effect of digoxin; hence, it is not the most critical instruction to provide.

2. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

3. Which nursing activity is within the scope of practice for the practical nurse?

• A. Complete an admission assessment in the normal newborn nursery
• B. Discontinue a central venous catheter that has become dislodged
• C. Observe a client rotate the subcutaneous site for an insulin pump
• D. Monitor a continuous narcotic epidural for a postoperative client

Correct answer: C

Rationale: The correct answer is C: 'Observe a client rotate the subcutaneous site for an insulin pump.' This activity is within the scope of practice for a practical nurse as it involves observing and ensuring proper technique for using an insulin pump, which aligns with their training and responsibilities. Choices A, B, and D are beyond the typical scope of practice for a practical nurse. Completing an admission assessment for a newborn nursery is usually performed by a registered nurse. Discontinuing a dislodged central venous catheter and monitoring a narcotic epidural require advanced skills and knowledge, usually carried out by registered nurses or advanced practice nurses.

4. A client is prescribed warfarin for the prevention of thromboembolism. What dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Maintain a consistent intake of vitamin K-rich foods
• C. Avoid all foods containing vitamin K
• D. Consume a high-protein diet

Correct answer: B

Rationale: The correct answer is B. Maintaining a consistent intake of vitamin K-rich foods is important for patients taking warfarin as it helps keep the effects of the medication stable. Choice A is incorrect because while green leafy vegetables are high in vitamin K, they should not be avoided completely but rather consumed consistently. Choice C is also incorrect as avoiding all foods containing vitamin K can lead to fluctuations in warfarin's effectiveness. Choice D is incorrect as a high-protein diet is not specifically recommended for patients taking warfarin.

5. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
