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. A client with chronic obstructive pulmonary disease (COPD) is struggling to breathe. What should the nurse do first?

• A. Increase the oxygen flow rate according to the prescription
• B. Encourage the client to perform pursed-lip breathing
• C. Prepare for emergency intubation
• D. Assess the client's oxygen saturation and breath sounds

Correct answer: D

Rationale: The correct first action for a nurse when a client with COPD is struggling to breathe is to assess the client's oxygen saturation and breath sounds. This initial assessment is crucial in determining the severity of the client's condition and the appropriate intervention. Increasing the oxygen flow rate without proper assessment can potentially be harmful, as COPD clients have a risk of retaining carbon dioxide. Encouraging pursed-lip breathing can be beneficial but should come after assessing the client's current status. Emergency intubation is a drastic measure and should only be considered after a comprehensive assessment indicates the need for it.

3. The nurse is caring for a client with an indwelling urinary catheter. What is the most important action to prevent catheter-associated urinary tract infections (CAUTI)?

• A. Perform hand hygiene before and after handling the catheter
• B. Change the catheter every 72 hours
• C. Apply antibiotic ointment at the insertion site
• D. Irrigate the catheter daily

Correct answer: A

Rationale: Performing hand hygiene before and after handling the catheter is crucial in preventing catheter-associated urinary tract infections (CAUTI). This practice helps minimize the risk of introducing harmful microorganisms into the urinary tract. Changing the catheter every 72 hours is not recommended unless clinically indicated as it can increase the risk of infection. Applying antibiotic ointment at the insertion site is not a standard practice and may contribute to antibiotic resistance. Irrigating the catheter daily is unnecessary and can introduce pathogens into the urinary tract, increasing the risk of infection.

4. In a community health setting, which individual is at highest risk for contracting an HIV infection?

• A. 17-year-old who is sexually active with numerous partners
• B. 34-year-old homosexual in a monogamous relationship
• C. 30-year-old cocaine user who inhales and smokes drugs
• D. 45-year-old who has received two blood transfusions in the past 6 months

Correct answer: C

Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.

5. A client with diabetes mellitus is scheduled for surgery. What is the most important preoperative instruction the nurse should provide?

• A. Take your insulin as usual
• B. Do not eat or drink after midnight
• C. Monitor your blood glucose closely
• D. Bring your glucose meter to the hospital

Correct answer: B

Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.
