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 client who was given a diagnosis of hypertension 3 months ago is at the clinic for a checkup. Which type of database does the nurse use in performing an assessment?

• A. Emergency
• B. Follow-up
• C. Complete (total)
• D. Problem-centered

Correct answer: B

Rationale: The correct answer is 'Follow-up.' A follow-up database is used to assess the status of an identified problem at regular intervals. An emergency database is for urgent data collection during life-saving measures. A complete database involves a full health history and physical examination. A problem-centered (episodic) database focuses on a limited or short-term issue, typically centered around one problem or body system.

3. A client has just returned from surgery where a femoral-popliteal bypass was performed. The nurse has assessed the client and is unable to feel a pulse at either the dorsalis pedis or the posterior tibial sites of the left foot. The foot feels warm, and the color is pink. What action should the nurse perform next to prevent ischemia?

• A. Notify the physician immediately
• B. Obtain a Doppler device to check for pulses, and notify the physician if they are still absent
• C. Wait 30 minutes and recheck the pulses
• D. Document the finding

Correct answer: B

Rationale: The nurse should immediately obtain a Doppler device and recheck the pulses. The dorsalis pedis and posterior tibial pulses can be difficult to assess and might need to be verified with a Doppler device. Since the client just had surgery with a risk of arterial insufficiency, close monitoring is crucial. If pulses are not palpable, it indicates an emergent situation requiring immediate physician notification. Waiting 30 minutes before reassessment could lead to foot ischemia. While documenting findings is essential, it should follow pulse confirmation or necessary interventions to ensure the client's foot viability.

4. Which of these is not a symptom of Serotonin Syndrome?

• A. edema
• B. fever
• C. confusion
• D. tremors

Correct answer: A

Rationale: Serotonin syndrome, caused by an excess of serotonin, typically presents with symptoms such as altered mental status (confusion), neuromuscular abnormalities (tremors), and autonomic dysfunction (fever). Edema, which refers to swelling caused by fluid retention in the body tissues, is not a common symptom associated with serotonin syndrome. Therefore, the correct answer is 'edema.' Choice A, 'edema,' is the correct answer as it is not typically seen in serotonin syndrome. Choice B, 'fever,' is a symptom of serotonin syndrome, as it can cause autonomic dysfunction. Choice C, 'confusion,' is a common symptom due to altered mental status in serotonin syndrome. Choice D, 'tremors,' is also a common symptom due to neuromuscular abnormalities in serotonin syndrome.

5. During a well-baby examination, the nurse measures the head circumference, and it is the same as the chest circumference. On the basis of this measurement, what action should the nurse take?

• A. Document these measurements in the infant's health care record.
• B. Tell the mother that the infant is growing faster than expected.
• C. Suggest to the health care provider that a skull x-ray be performed.
• D. Report the presence of hydrocephalus to the health care provider.

Correct answer: A

Rationale: The head circumference growth rate during the first year is approximately 0.4 inches (1 cm) per month. By 10 to 12 months of age, the infant's head and chest circumferences are equal. In this case, where the head circumference matches the chest circumference, it is a normal finding in infants around 10-12 months. Therefore, the most appropriate action is to document these measurements in the infant's health care record. Suspecting hydrocephalus or suggesting a skull x-ray would be premature and not indicated based on this measurement. Similarly, telling the mother that the infant is growing faster than expected is not accurate and could cause unnecessary concern.
