Which of the following measures is not recommended to prevent pressure ulcers?

Correct Answer: A

Rationale: Massaging a reddened area can cause further tissue damage by increasing pressure on already compromised skin. The other options, such as using specialized mattresses, adhering to repositioning schedules, and maintaining good skin care, are all recommended strategies to prevent pressure ulcers by reducing pressure and friction on vulnerable areas of the skin.

Correct Answer: D

Rationale: Hip fracture is the most common injury among elderly persons. As people age, their bones become more fragile, making them more susceptible to hip fractures, often resulting from falls. These fractures can significantly impact an elderly person's quality of life and mobility, making them a significant concern in geriatric care.

Correct Answer: B

Rationale: A positive guaiac test is used to detect the presence of occult (hidden) blood in the stool, suggesting bleeding from the gastrointestinal tract. It is a rapid screening test that can provide immediate information to the healthcare provider about possible gastrointestinal bleeding in patients presenting with symptoms such as nausea, vomiting, diarrhea, and severe abdominal pain.

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: B

Rationale: The most effective form of universal precautions is to discard all used uncapped needles and syringes in an impenetrable protective container. This practice minimizes the risk of needle-stick injuries, which are a significant concern when dealing with used needles. By safely disposing of uncapped needles, healthcare providers can protect themselves and others from potential exposure to bloodborne pathogens.

Correct Answer: C

Rationale: Primary nursing care units have been proven to be highly satisfying for both patients and nurses. This model promotes a consistent and continuous relationship between a patient and a primary nurse, leading to improved communication, personalized care, and overall satisfaction for both parties involved.

Correct Answer: A

Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure.

While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.

Correct Answer: B

Rationale: Vitamin C requirements are increased during infancy, childhood, and pregnancy due to growth and development. However, during young adulthood, the body generally requires a consistent amount of Vitamin C as it is not undergoing rapid growth or physiological changes that necessitate an increase in Vitamin C intake.
