Nursing Elites

1. Which of the following procedures always requires surgical asepsis?

• A. Vaginal instillation of conjugated estrogen
• B. Urinary catheterization
• C. Nasogastric tube insertion
• D. Colostomy irrigation

Correct answer: B

Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity. Vaginal instillation of conjugated estrogen, nasogastric tube insertion, and colostomy irrigation do not always require surgical asepsis as they involve different levels of sterility and infection control measures.

2. Which of the following patients is at greater risk for contracting an infection?

• A. A patient with leukopenia
• B. A patient receiving broad-spectrum antibiotics
• C. A postoperative patient who has undergone orthopedic surgery
• D. A newly diagnosed diabetic patient

Correct answer: A

Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.

3. All of the following interventions are correct when using the Z-track method of drug injection except:

• A. Prepare the injection site with alcohol
• B. Use a needle that is at least 1” long
• C. Aspirate for blood before injection
• D. Rub the site vigorously after the injection to promote absorption

Correct answer: D

Rationale: When using the Z-track method of drug injection, it is important to prepare the injection site with alcohol to ensure cleanliness, use a needle that is at least 1” long to reach the muscle tissue, and aspirate for blood before injection to verify correct needle placement. However, rubbing the site vigorously after the injection is not recommended as it can cause medication to leak into subcutaneous tissue, compromising the medication's intended absorption and efficacy.

4. What is the best description of resonance?

• A. Sounds created by air-filled structures
• B. Short, high-pitched, and thudding
• C. Moderately loud with a musical quality
• D. Drum-like

Correct answer: A

Rationale: Resonance refers to the quality of sound produced by vibrations that are reinforced by other vibrations of the same frequency. In the context of the human body, resonance is often associated with sounds produced by air-filled structures like the lungs, vocal cords, and resonating cavities. Therefore, the best description of resonance from the given options is 'Sounds created by air-filled structures.' This choice aligns with the concept of resonance as it relates to sound production in the human body. Choices B, C, and D are incorrect as they do not specifically relate to the concept of resonance or its association with air-filled structures.

5. What is the meaning of PRN?

• A. When advice
• B. Immediately
• C. When necessary
• D. Now

Correct answer: C

Rationale: The correct meaning of PRN is 'when necessary.' The abbreviation 'PRN' comes from the Latin term 'pro re nata,' which is commonly used in medical contexts to indicate that a medication should be taken as needed, not at scheduled intervals. Choice A ('When advice') is incorrect as PRN does not refer to seeking advice. Choice B ('Immediately') is incorrect as PRN does not imply urgency. Choice D ('Now') is incorrect as PRN does not mean 'immediate' but rather 'as needed.' Therefore, the correct answer is C, 'When necessary.'
