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. Which of the following client groups should the nurse recognize as the fastest-growing segment of the homeless population?

• A. single, adult men
• B. single mothers with 2 or 3 children
• C. runaway adolescents
• D. single, adult women

Correct answer: B

Rationale: Single mothers with two or three children are indeed the fastest-growing segment of the homeless population. These families, where the majority of children are under the age of five, make up more than one-third of the homeless population in the United States. While single, adult men have traditionally been the largest group in the homeless population, single mothers with children have been increasing in numbers. Runaway adolescents, although a significant group of homeless children, do not represent the fastest-growing segment of the homeless population. Single, adult women are not specified as the fastest-growing segment.

3. A nurse assisting with data collection is preparing to auscultate for bowel sounds. The nurse should use which technique?

• A. Begin in the right lower quadrant.
• B. Use the bell end of the stethoscope.
• C. Hold the stethoscope lightly against the skin.
• D. Listen for at least 5 minutes before deciding that bowel sounds are absent.

Correct answer: A

Rationale: To auscultate for bowel sounds, the nurse should use the diaphragm end piece of the stethoscope as bowel sounds are relatively high pitched. The stethoscope should be held lightly against the skin to avoid stimulating more bowel sounds. The nurse should begin in the right lower quadrant at the ileocecal valve, where bowel sounds are normally present. It is recommended to listen for 5 minutes before deciding that bowel sounds are absent to ensure a thorough assessment. Choice B is incorrect because the bell end is used for low-pitched sounds such as heart sounds. Choice C is incorrect as holding the stethoscope firmly and deeply can cause unnecessary bowel sound stimulation. Choice D is incorrect as listening for 1 minute is insufficient to determine the presence or absence of bowel sounds.

4. A pregnant client is scheduled to undergo a transabdominal ultrasound, and the nurse provides information to the client about the procedure. The nurse provides which information?

• A. The procedure typically takes 10 to 30 minutes.
• B. She may need to drink fluids before the test and may not void until the test has been completed.
• C. A probe coated with gel will be inserted into the vagina.
• D. She will be positioned on her back, with her head elevated and turned slightly to one side.

Correct answer: B

Rationale: The correct answer is that the client may need to drink fluids before the test and may not void until the test has been completed. For a transabdominal ultrasound, the woman is positioned on her back with her head elevated and turned slightly to one side to prevent supine hypotension. A wedge or rolled blanket is placed under one hip to help her maintain this position comfortably. If a full bladder is necessary, the woman is instructed to drink several glasses of clear fluid 1 hour before the test and told that she should not void until the test has been completed. Warm mineral oil or transmission gel is spread over her abdomen, and the sonographer slowly moves a transducer over the abdomen to obtain a picture. The procedure typically takes 10 to 30 minutes, making choice A incorrect. Choice C is incorrect because a probe is not inserted into the vagina for a transabdominal ultrasound. Choice D is incorrect because the woman is positioned on her back with her head elevated and turned slightly to one side, not specifically on her back.

5. What is the primary theory that explains a family's concept of health and illness?

• A. Health Belief Model
• B. Education Factor
• C. Family Health Belief Model
• D. Family Dynamics Model

Correct answer: A

Rationale: The correct answer is the Health Belief Model. The Health Belief Model is a widely recognized theory that explains individuals' perceptions and behaviors related to health and illness. It considers factors such as perceived susceptibility, severity of health issues, benefits of action, and barriers to taking action. Choices B, C, and D are incorrect. Choice B, 'Education Factor,' is too general and does not specifically address a family's concept of health and illness. Choice C, 'Family Health Belief Model,' is a combination of terms and not a recognized theory. Choice D, 'Family Dynamics Model,' focuses on family interactions rather than explaining a family's concept of health and illness.
