Nursing Elites

1. 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.

2. The nurse is teaching a client with hypertension about lifestyle modifications. Which recommendation is most effective for lowering blood pressure?

• A. Increase intake of red meat
• B. Engage in regular physical activity
• C. Consume a high-sodium diet
• D. Limit fluid intake to 1 liter per day

Correct answer: B

Rationale: Engaging in regular physical activity is a highly effective recommendation for lowering blood pressure and improving overall cardiovascular health. Regular exercise helps to strengthen the heart, improve blood circulation, and manage weight, all of which contribute to reducing blood pressure levels. Choices A, C, and D are incorrect. Increasing intake of red meat can lead to higher saturated fat consumption, which is detrimental to heart health. Consuming a high-sodium diet can exacerbate hypertension by increasing blood pressure. Limiting fluid intake to 1 liter per day may lead to dehydration and is not a recommended approach for managing hypertension.

3. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?

• A. Endotracheal cuff pressure greater than 25 cm H2O.
• B. Decreased lung compliance during ventilation.
• C. Bilateral crackles with increased secretions.
• D. Restless client who is biting the endotracheal tube.

Correct answer: D

Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.

4. A client with a urinary tract infection is prescribed antibiotics. What should the nurse inform the client about antibiotic therapy?

• A. It may interfere with oral contraceptive effectiveness
• B. It can cause drowsiness
• C. It should be taken with meals
• D. Completing the full course is crucial

Correct answer: D

Rationale: Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. Informing the client about the importance of finishing the prescribed course helps in ensuring the effectiveness of the treatment and reduces the risk of recurrence. Choice A is incorrect because antibiotics do not generally interfere with oral contraceptive effectiveness. Choice B is incorrect because drowsiness is not a common side effect of antibiotics. Choice C is incorrect because while some antibiotics may need to be taken with meals, it is not a universal rule for all antibiotics.

5. Which client is at the highest risk for developing pressure ulcers?

• A. A 50-year-old client with a fractured femur
• B. A 30-year-old client with diabetes mellitus
• C. A 65-year-old client with limited mobility
• D. A 70-year-old client with a history of stroke

Correct answer: C

Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.
