Nursing Elites

1. What is the most common sign of a localized infection?

• A. Fever
• B. Elevated white blood cell count
• C. Redness, warmth, and swelling at the site of infection
• D. Chills and shivering

Correct answer: C

Rationale: The correct answer is C: Redness, warmth, and swelling at the site of infection. These signs are typical indications of a localized infection, representing inflammation and the body's immune response to the pathogen. Fever (choice A) is a systemic response and not specific to a localized infection. Elevated white blood cell count (choice B) can be seen in both localized and systemic infections. Chills and shivering (choice D) are more related to the body's response to fever and not specifically indicative of a localized infection.

2. According to the principle of asepsis, which situation should the PN consider to be sterile?

• A. A one-inch border around the edges of a sterile field set up in the operating room
• B. A sterile glove that the PN thinks might have touched hair
• C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp table top
• D. An open sterile Foley catheter kit set up on a table at the PN's waist level

Correct answer: A

Rationale: According to the principle of asepsis, the one-inch border around the edges of a sterile field set up in the operating room is considered non-sterile, while the central area remains sterile. Therefore, the PN should consider the situation described in choice A to be sterile. Choice B is incorrect because a glove that may have touched hair is contaminated. Choice C is incorrect as a sterile item placed on a damp surface is considered contaminated. Choice D is incorrect as a sterile kit set up at the PN's waist level is prone to contamination.

3. While caring for a client with an AV fistula in the left forearm, the nurse observed a palpable buzzing sensation over the fistula. What action should the nurse take?

• A. Loosen the dressing of the fistula
• B. Report the presence of a bounding pulse
• C. Document that the fistula is intact
• D. Apply gentle pressure over the site

Correct answer: C

Rationale: The correct answer is C: Document that the fistula is intact. The palpable buzzing sensation (known as a thrill) over the AV fistula indicates proper functioning. It is essential for the nurse to document this finding to ensure ongoing monitoring of the fistula's status. Choices A, B, and D are incorrect. Choice A is incorrect because there is no indication to loosen the dressing. Choice B is incorrect as a bounding pulse is not associated with the palpable buzzing sensation of a thrill. Choice D is incorrect as applying pressure over the site is not necessary for this situation.

4. A post-operative client is prescribed sequential compression devices (SCDs) while on bed rest. What is the primary purpose of this device?

• A. To prevent deep vein thrombosis (DVT).
• B. To improve circulation in the legs.
• C. To prevent pressure ulcers.
• D. To alleviate post-operative pain.

Correct answer: A

Rationale: The correct answer is A: 'To prevent deep vein thrombosis (DVT).' Sequential compression devices (SCDs) are primarily used to prevent deep vein thrombosis (DVT) by promoting blood flow in the legs and reducing venous stasis, which is a common risk for post-operative clients who are on bed rest. While SCDs do improve circulation in the legs indirectly, their primary purpose is DVT prevention. Preventing pressure ulcers is typically achieved through repositioning and support surfaces, not with SCDs, making choice C incorrect. SCDs are not used to alleviate post-operative pain, so choice D is also incorrect.

5. Which of the following is the most effective way to prevent the spread of infection in a healthcare setting?

• A. Using sterile gloves
• B. Wearing a face mask
• C. Performing hand hygiene
• D. Using disposable equipment

Correct answer: C

Rationale: Performing hand hygiene is the most effective way to prevent the spread of infection in a healthcare setting. Hand hygiene helps remove pathogens that could be transmitted through direct contact, making it a crucial practice in infection control. While using sterile gloves and disposable equipment are important in certain situations, they do not address the potential transmission of pathogens through direct contact, unlike hand hygiene. Wearing a face mask is important for respiratory precautions but may not be as effective as hand hygiene in preventing the spread of infections through direct contact.
