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. Constipation is a common side effect of Tylenol #3, which contains codeine. Codeine can slow down bowel movements, leading to constipation. Monitoring for constipation and implementing management strategies is crucial. Choices A, B, and C are incorrect because bruising at the operative site, elevated heart rate, and decreased platelet count are not commonly associated side effects of Tylenol #3.

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: B

Rationale: The correct answer is B: 'Oozing liquid stool.' In a paralyzed client, oozing liquid stool is a common sign of fecal impaction. This occurrence requires prompt intervention to prevent complications. Choice A, 'Presence of blood in stools,' is more indicative of gastrointestinal bleeding rather than fecal impaction. Choice C, 'Continuous rumbling flatulence,' is associated with gas movement in the intestines and not specifically linked to fecal impaction. Choice D, 'Absence of bowel movements,' could be a sign of constipation but does not directly point towards fecal impaction.

Correct Answer: D

Rationale: The correct answer is D because bright red urine without pain suggests possible hematuria, which is a concerning symptom that requires immediate medical evaluation. Option A mentions bright red urine but also relates it to starting a period, which is less likely to be an urgent issue. Option B describes increased urination, which may indicate hyperglycemia but doesn't require immediate evaluation. Option C presents symptoms more related to a urinary tract infection that may not require urgent attention.
