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.

Which deficiency is most commonly seen in individuals with alcohol use disorder?
- A. Thiamine
- B. Riboflavin
- C. Pyridoxine
- D. Pantothenic acid
Correct Answer: A
Rationale: Thiamine deficiency, also known as Vitamin B1 deficiency, is the most common vitamin deficiency seen in individuals with alcohol use disorder. Chronic alcohol consumption can lead to decreased thiamine absorption and utilization, as well as poor dietary intake. Thiamine deficiency can result in serious neurological complications, such as Wernicke-Korsakoff syndrome, making it essential to address thiamine supplementation in individuals with alcohol use disorder.
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.
Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?
- A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
- B. Circulatory overload due to hypervolemia
- C. Respiratory excitement
- D. Inhibition of the respiratory hypoxic stimulus
Correct Answer: D
Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.
To assess the kidney function of a patient with an indwelling urinary (Foley) catheter, the nurse measures the hourly urine output. When should she notify the physician?
- A. Less than 30 ml/hour
- B. 64 ml in 2 hours
- C. 90 ml in 3 hours
- D. 125 ml in 4 hours
Correct Answer: A
Rationale: Notifying the physician is necessary when the urine output is less than 30 ml/hour as it indicates impaired kidney function. Adequate urine output is essential for monitoring kidney function, and a urine output less than 30 ml/hour could suggest potential renal issues that require medical attention.
