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. A nurse is determining the fetal heart rate (FHR) and places the fetoscope on the mother's abdomen to count the FHR. The nurse simultaneously palpates the mother's radial pulse and notes that it is synchronized with the sounds heard through the fetoscope. Which action should the nurse take?

• A. Count the FHR for 60 seconds, ensuring that it is synchronized consistently with the mother's radial pulse.
• B. Move the fetoscope to another area on the mother's abdomen to locate the fetal heart.
• C. Ask the mother to lie still while both the FHR and the radial pulse rate are counted.
• D. Count the FHR for 30 seconds and then count the radial pulse rate of the mother for 30 seconds.

Correct answer: B

Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.

3. During a routine health screening, the nurse should talk to the parents of a 1-year-old child about which of the following?

• A. the potential hazards of accidents
• B. appropriate nutrition now that the child has been weaned from breastfeeding
• C. toilet training
• D. how to prevent accidents in the house

Correct answer: A

Rationale: During a routine health screening for a 1-year-old child, discussing the potential hazards of accidents is crucial. Accidents are the primary source of injury in children and can be life-threatening. Addressing appropriate nutrition now that the child has been weaned from breastfeeding should have already been discussed. Toilet training is important but is typically addressed at a later age as one year is too early for this milestone. While preventing accidents in the house is important, focusing on the potential hazards of accidents in general is more comprehensive and critical for the child's safety.

4. Which of the following is not a nursing responsibility when preparing the client for central line insertion?

• A. advancing the guidewire
• B. explaining the procedure to the client
• C. maintaining sterile technique
• D. ensuring necessary consents are signed

Correct answer: A

Rationale: When preparing a client for central line insertion, nursing responsibilities include explaining the procedure to the client, ensuring necessary consents are signed according to the facility policy, and maintaining sterile technique when preparing the equipment and supplies. Advancing the guidewire is typically performed by the practitioner inserting the central line, not the nurse. It requires specialized training and expertise beyond the scope of nursing practice. Therefore, the correct answer is advancing the guidewire. Option A is the correct answer because it delineates an activity that is not within the usual scope of nursing practice during central line insertion preparation. Options B, C, and D are incorrect as they reflect essential nursing responsibilities in this context.

5. The client should include all of the following in teaching an obese client about nutritional needs and weight loss except:

• A. knowledge of food and food products
• B. development of a positive mental attitude
• C. adequate exercise
• D. starting a fast weight-loss diet

Correct answer: D

Rationale: When educating an obese client about nutritional needs and weight loss, it is crucial to emphasize a holistic approach that involves understanding food and food products, fostering a positive mental attitude, and incorporating adequate exercise. Initiating a fast weight-loss diet is not advisable due to potential health risks and lack of long-term sustainability. Therefore, this option stands out as the exception and should not be part of the client's learning. Choices A, B, and C are essential components of a healthy weight-loss plan and should be included in the client's education.
