QUESTIONS AND CORRECT ANSWERS
What is a pressure ulcer and how does it develop in patients?
CORRECT ANSWERS
A pressure ulcer, also called a bedsore, is a localized injury to the skin and underlying tissues,
usually over bony areas, caused by prolonged pressure. Continuous pressure restricts blood flow,
leading to tissue ischemia and eventual skin breakdown. Other contributing factors include
friction, shear, moisture, and immobility. Recognizing its development is essential for early
prevention and care.
What are the main risk factors for developing pressure ulcers in hospitalized patients?
CORRECT ANSWERS
Risk factors include immobility, advanced age, poor nutrition, incontinence, chronic illnesses,
and reduced sensory perception. Friction and shear during patient movement also increase
vulnerability. Patients with compromised circulation or low skin integrity are particularly at risk.
Understanding these factors allows nurses to implement preventive measures effectively.
How does immobility contribute to the formation of pressure ulcers?
CORRECT ANSWERS
Immobility prevents patients from shifting weight, leading to continuous pressure on bony
prominences like heels, elbows, and sacrum. This pressure restricts blood flow, resulting in tissue
ischemia and breakdown. Even short periods of unrelieved pressure can cause early damage.
Nurses must encourage repositioning and assist with mobility to prevent ulcers.
What role does nutrition play in pressure ulcer prevention?
CORRECT ANSWERS
Nutrition is crucial for maintaining skin integrity and supporting tissue repair. Adequate protein,
vitamins A and C, and zinc help strengthen skin and promote healing. Malnutrition or
, dehydration weakens the skin and delays recovery. Nurses assess dietary intake and collaborate
with dietitians to optimize nutrition for at-risk patients.
Why is skin assessment crucial in preventing pressure ulcers?
CORRECT ANSWERS
Regular skin assessment allows early detection of redness, blanching, or skin breakdown. Early
identification enables timely interventions before ulcers form. Nurses focus on bony
prominences and areas exposed to friction or moisture. Documenting findings helps guide care
planning and preventive strategies.
How can repositioning prevent pressure ulcers?
CORRECT ANSWERS
Repositioning relieves prolonged pressure on vulnerable areas, improving blood circulation and
tissue oxygenation. Bedridden patients should be turned at least every two hours, while
wheelchair users should shift position hourly. Pillows and supports can reduce pressure and
prevent friction. Consistent repositioning is one of the most effective preventive measures.
What is the significance of using pressure-relieving devices in patients at risk?
CORRECT ANSWERS
Pressure-relieving devices such as specialized mattresses, cushions, and heel protectors
redistribute weight and reduce localized pressure. They prevent tissue ischemia and lower the
risk of ulcer development. These devices complement regular repositioning, especially for
immobile patients. Proper selection and use enhance patient comfort and protection.
How does moisture affect pressure ulcer development?
CORRECT ANSWERS
Excess moisture from sweat, incontinence, or wound exudate softens the skin and increases
susceptibility to breakdown. Moist skin is more prone to friction and shear injuries. Maintaining
dryness with barrier creams and absorbent products protects the skin’s integrity. Nurses must
implement moisture management as part of routine care.
