Correct Answer: A

Rationale: When using a Wood light during a skin examination, the room should be darkened to enhance the visibility of fluorescence. The Wood light emits long-wavelength ultraviolet light, highlighting certain skin conditions. Darkening the room aids in better visualization. Obtaining informed consent is a crucial aspect of healthcare but not directly related to using a Wood light. Obtaining a scalpel and a slide is unnecessary for a noninvasive Wood light examination. Anesthetizing the skin area is not required as the procedure is painless and noninvasive.

Correct Answer: D

Rationale: When performing the confrontation test to assess peripheral vision, the nurse should position at eye level with the client, cover one eye, and have the client cover the opposite eye. This approach allows the examiner to bring a small object into the visual field to evaluate the client's peripheral vision. The test aims to compare the client's peripheral vision with the examiner's vision to identify any visual field deficits. Choices A, B, and C are incorrect. Choice A pertains to testing color vision, which is not part of the confrontation test. Choice B describes a different procedure that involves advancing a target midline between the client and examiner, not the correct approach for the confrontation test. Choice C is inaccurate as it fails to include the essential step of positioning at eye level with the client, making it an incorrect representation of the confrontation test.

Correct Answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

Correct Answer: B

Rationale: When performing an abdominal assessment, the nurse auscultates the abdomen after inspection. Auscultation is done before palpation and percussion because these assessment techniques can increase peristalsis, which would yield a false interpretation of bowel sounds. This sequence helps prevent false interpretations of bowel sounds due to increased peristalsis caused by palpation and percussion. Options A, C, and D provide incorrect reasons for auscultating the abdomen before palpating and percussing it.

Correct Answer: A

Rationale: Dry skin is also called xerosis. In this condition, the epidermis lacks moisture or sebum and is often marked by a pattern of fine lines, scaling, and itching. Xerosis is the correct term for very dry skin. Pruritus is the symptom of itching, an uncomfortable sensation that prompts the urge to scratch the skin, but it does not specifically refer to dry skin. Seborrhea is a skin condition characterized by overproduction of sebum, leading to excessive oiliness or dry scales, not necessarily indicating very dry skin. Actinic keratoses are sun-related skin lesions that are premalignant and not associated with dry skin.
