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. Mr. H. is upset about being in the hospital for another day due to the high cost. The rights he is likely to demand include all of the following except:

• A. the right to examine and question the bill
• B. the right to reasonable response to requests
• C. the right to refuse treatment
• D. the right to confidentiality

Correct answer: D

Rationale: Confidentiality is the maintenance of privacy of information. The question does not suggest that confidentiality has been breached. In this scenario, Mr. H. is concerned about the cost and the length of his stay, which relates to his rights regarding billing, treatment, and response to requests. The right to confidentiality, though important, is not directly related to his current situation of being upset about the high cost and extended stay. Mr. H. is more likely to demand the right to examine and question the bill to understand the charges, the right to reasonable response to requests regarding his care and stay, and the right to refuse treatment if he wishes. Therefore, the correct answer is the right to confidentiality, as it is not a primary concern in this context.

3. A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?

• A. The client is legally blind.
• B. The client has normal vision.
• C. The client can read at a distance of 20 feet what a client with normal vision can read at 80 feet.
• D. The client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.

Correct answer: D

Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.

4. A nurse is preparing to auscultate a fetal heart rate (FHR). The nurse performs the Leopold maneuvers to determine the position of the fetus and then places the fetoscope over which part of the fetus?

• A. Back of the fetus
• B. Carotid artery in the neck of the fetus
• C. Brachial area of one extremity of the fetus
• D. Chest of the fetus

Correct answer: A

Rationale: The nurse would use the Leopold maneuvers to identify the position of the fetus and determine the location of the fetal back. The fetal heart rate (FHR) is most easily heard through the fetal back because it usually lies closest to the surface of the maternal abdomen. Auscultation of the FHR over the chest, carotid artery, or brachial area is not possible due to the fetal position within the maternal abdomen. Placing the fetoscope over the carotid artery or brachial area would not yield the fetal heart rate, and the chest area is not typically used for auscultating the FHR.

5. When a 25-year-old client complains of chest congestion and cough after previously presenting with cold symptoms, what data should the nurse collect?

• A. Data related to follow-up care
• B. A complete health database
• C. Data related to the respiratory system
• D. Data related to the treatment for the cold

Correct answer: C

Rationale: In this case, the nurse should collect data related to the respiratory system since the client is presenting with symptoms like chest congestion and cough, indicating a respiratory issue. Focusing on the respiratory system will help gather pertinent information to assess the current problem comprehensively. A complete health database involves a detailed health history and full physical examination, which is beyond the immediate scope of the presenting issue. Data related to follow-up care is premature as the primary focus should be on assessing the current respiratory symptoms. Data related to the treatment for the cold is not the priority at this stage, as understanding the underlying respiratory problem is crucial for appropriate intervention.
