Correct Answer: A

Rationale: The correct answer is Vitamin A. Fat-soluble vitamins essential for patients with pancreatitis include A, D, E, and K, aiding in proper nutrient absorption. Vitamin B1 (Choice B), also known as thiamine, is a water-soluble vitamin and not a fat-soluble one. Vitamin C (Choice C) is another water-soluble vitamin and not a fat-soluble one. Vitamin B12 (Choice D) is also a water-soluble vitamin and not one of the fat-soluble vitamins crucial for patients with pancreatitis.

Correct Answer: A

Rationale: A malnourished client on bed rest is at the highest risk for developing decubitus ulcers due to a combination of factors such as poor nutritional status and immobility. Malnourished individuals have compromised skin integrity, making them more susceptible to pressure ulcers. Being on bed rest further exacerbates this risk as constant pressure on bony prominences can lead to tissue damage. Although the other choices may also be at risk for developing decubitus ulcers, the malnourished client on bed rest presents the highest risk due to the combination of malnutrition and immobility.

Correct Answer: D

Rationale: The correct answer is D because a recent illness, such as a cold, can trigger a vaso-occlusive crisis in sickle cell disease. This crisis is often precipitated by infections or other illnesses that cause a systemic inflammatory response, leading to vaso-occlusion. Choices A, B, and C do not directly relate to the etiology of a vaso-occlusive crisis in sickle cell disease, making them incorrect.

Correct Answer: C

Rationale: The correct answer is C. A respiratory rate of 16 breaths per minute is within normal limits; however, changes in breathing patterns can indicate respiratory distress, which is concerning, especially in a client receiving treatment for hypertension. A heart rate of 90 beats per minute may not be alarming if the client is at rest. A blood pressure of 120/80 mm Hg is within the normal range for a healthy adult. A temperature of 98.6 degrees Fahrenheit is also considered normal, showing no immediate cause for concern in this scenario.

Correct Answer: D

Rationale: The correct answer is D. Placing the bed in the lowest position, ensuring wheels are locked, and positioning it against the wall is the preferred bed position for a client in an extended care facility on a falls risk prevention protocol. This setup helps minimize the risk of falls by providing a stable and secure environment. Choices A, B, and C do not address key factors such as having the bed in the lowest position and placing it against the wall, which are crucial in preventing falls in such a setting.
