Correct Answer is C

Explanation

Choice A rationale: Using enemas should not be the first response to constipation. There are various types of laxatives with different mechanisms of action that can be tried before resorting to enemas.
Choice B rationale: Habitual laxative use can contribute to chronic constipation, but it is not the most common cause. It is essential to identify and address the underlying cause of constipation.
Choice C rationale: If laxatives are not effective, trying a laxative with a different mechanism of action may be more successful in relieving constipation.
Choice D rationale: Chronic constipation should be assessed and addressed, as it can lead to complications and should not be dismissed as insignificant.

A. Stage III Pressure Ulcer B. Stage IV Pressure Ulcer C. Stage II Pressure Ulcer D. Unstageable Ulcer

Correct Answer is B

Explanation

Choice A rationale: Stage III pressure ulcers involve full-thickness tissue loss with visible fat but do not extend to the underlying muscle.
Choice B rationale: Stage IV pressure ulcers involve full-thickness tissue loss with exposed muscle, bone, or other structures.
Choice C rationale: Stage II pressure ulcers involve partial-thickness skin loss but do not extend into the deeper layers.
Choice D rationale: Unstageable ulcers have a base covered by slough or eschar, making it difficult to assess the depth of tissue involvement. In this case, the wound's base is described as muscle, indicating a stage IV pressure ulcer.
