Nursing Elites

1. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

2. When performing the confrontation test to assess peripheral vision, what action should the nurse take?

• A. Asks the client to identify a small object brought into the visual field
• B. Has the client cover one eye while the nurse covers one eye and slowly advances a target midline between them
• C. Covers one eye, while the client covers the opposite eye, and brings a small object into the visual field
• D. Positions at eye level with the client, covers one eye, and has the client cover the opposite eye, then brings a small object into the visual field

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.

3. When a couple experiencing infertility presents for a fertility workup, which of the following procedures should the nurse prepare the couple to have first?

• A. Hysterosalpingography
• B. Semen analysis
• C. Endometrial biopsy
• D. Transvaginal ultrasound

Correct answer: B

Rationale: Semen analysis is the most appropriate initial diagnostic test for a couple experiencing infertility. It is the least invasive of the listed tests, and since male factor infertility contributes to around 35% of cases, assessing semen parameters early is crucial. Hysterosalpingography is a radiographic test to evaluate tubal patency and uterine cavity abnormalities. Endometrial biopsy assesses endometrial receptivity post-ovulation. Transvaginal ultrasound is mainly used in infertility treatment to monitor follicle development, oocyte maturity, and luteal phase defects. Choices A, C, and D are more invasive, require specialized expertise, and are costlier. If semen analysis yields normal results, further tests may be warranted.

4. A 35-year-old Latin-American client wishes to lose weight to reduce her chances of developing heart disease and diabetes. The client states, "I do not know how to make my diet work with the kind of foods that my family eats."? What should the nurse do first to help the client determine a suitable diet for disease prevention?

• A. Provide her with copies of the approved dietary guidelines from the American Diabetic Association and the American Heart Association.
• B. Ask the client to provide a list of the types of foods she eats to determine how to best meet her needs.
• C. Provide a high-protein diet plan for the client.
• D. Provide the client with information related to risk factors for heart disease and diabetes.

Correct answer: B

Rationale: The correct answer is to ask the client to provide a list of the types of foods she eats to determine how to best meet her needs. Assessment is the first step in helping the client establish a suitable diet for disease prevention. By understanding the client's current dietary habits, the nurse can tailor recommendations based on the approved dietary guidelines from the American Diabetic Association and the American Heart Association. Providing a high-protein diet plan without assessing the client's current diet may not align with her cultural preferences or health goals. While educating the client on risk factors for heart disease and diabetes is essential, it is not the initial step in developing a personalized dietary plan.

5. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

• A. Tests the right eye, then tests the left eye, and finally tests both eyes together
• B. Assesses both eyes together, then assesses the right and left eyes separately
• C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
• D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

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.
