Which action by a family member of a client with a wound requiring sterile dressings would indicate the need for additional teaching?

Correct Answer: D

Rationale: The correct answer is D because using a back-and-forth motion while cleaning the wound introduces the risk of cross-contamination. Cleaning should be done in a gentle, single-direction motion to prevent spreading microorganisms. Placing the old dressing in a plastic bag (A) is appropriate for disposal. Changing the dressing without wearing a mask (B) is not necessary unless there are specific respiratory concerns. Donning nonsterile gloves before removing the old dressing (C) is incorrect, as sterile gloves should be worn to prevent contamination.

Correct Answer: C

Rationale: The correct answer is C. Applying moisturizing lotion several times a day is recommended for clients with psoriasis to help maintain skin hydration and reduce itching and irritation. It helps to soothe and protect the skin barrier. Showering twice a day (choice A) can strip the skin of natural oils, exacerbating dryness. Soaking in hot water (choice B) can worsen inflammation and dry out the skin. Covering affected areas when in contact with others (choice D) may be necessary for infection control but does not address the primary skin care needs of psoriasis.

Correct Answer: C

Rationale: The correct answer is C, the hypogastric region. The urinary bladder is located in the pelvis, specifically in the hypogastric region. To image the bladder accurately, the camera must be focused on this region to capture the bladder's position and shape. The other choices (A, B, D) are incorrect as they do not correspond to the anatomical location of the urinary bladder. Option A is in the upper abdomen, option B is in the lower back, and option D is in the central abdomen, none of which are where the bladder is located. Focusing on the hypogastric region ensures the proper visualization of the urinary bladder in an x-ray image.

Correct Answer: C

Rationale: The correct answer is C: To store energy. The hypodermis serves as a storage site for fat, which acts as an energy reserve for the body. It helps to insulate the body and regulate temperature indirectly, but its primary function is energy storage. A: While the hypodermis does provide some protection and cushioning, its main function is not to protect the body from the environment. B: While the hypodermis does help with insulation, its function is not primarily to regulate body temperature. D: While the hypodermis does have multiple functions, its primary role is energy storage, so not all of the above are correct.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." Stem cell therapy can regenerate damaged skin cells, 3D printing can create customized skin grafts, and nanotechnology can deliver drugs directly to affected areas. Each technology plays a crucial role in improving the treatment of skin diseases and injuries by addressing different aspects of the healing process. Choosing only one option would limit the scope and effectiveness of treatment options available.
