Which of the following patients is at greatest risk for developing pressure ulcers?

Correct Answer: B

Rationale: The correct answer is B. An elderly patient who is incontinent, bedridden, and suffering from a serious illness like gastric cancer is at the highest risk for developing pressure ulcers. Being bedridden and incontinent increases the pressure on certain areas of the body, leading to tissue damage and the development of pressure ulcers. Additionally, the patient's age and underlying health condition further contribute to their risk. It is crucial to identify and address such risk factors promptly to prevent the occurrence of pressure ulcers in vulnerable patients.

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.

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.

Correct Answer: D

Rationale: Palpating the midclavicular line is the correct technique for assessing the apical pulse. The apical pulse is located at the point of maximal impulse (PMI), which is typically at the fifth intercostal space at the midclavicular line. This technique allows healthcare providers to accurately assess the heart rate and rhythm by listening to the heart sounds directly at this point.

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.
