Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. During a funduscopic examination of a school-age child, the nurse notes a brilliant, uniform red reflex in both eyes. The nurse should recognize that this is which?

• A. A normal finding
• B. A sign of a possible visual defect and a need for vision screening
• C. An abnormal finding requiring referral to an ophthalmologist
• D. A sign of small hemorrhages, which usually resolve spontaneously

Correct answer: A

Rationale: A brilliant, uniform red reflex in both eyes is a normal finding, indicating that the retina is healthy and there are no significant obstructions in the visual pathway.

3. A mother brings 6-month-old Eric to the clinic for a well-baby checkup. She comments, "I want to go back to work, but I don't want Eric to suffer because I'll have less time with him." Which is the nurse's most appropriate answer?

• A. "I'm sure he'll be fine if you get a good babysitter."
• B. "You will need to stay home until Eric starts school."
• C. "Let's talk about the childcare options that will be best for Eric."
• D. "You should go back to work so Eric will get used to being with others."

Correct answer: C

Rationale: The best approach is to discuss childcare options that would suit Eric's needs, allowing the mother to make an informed decision without guilt or pressure.

4. What is the leading cause of morbidity and mortality in children with cystic fibrosis?

• A. Respiratory infections
• B. Malnutrition
• C. Diabetes
• D. Liver disease

Correct answer: A

Rationale: Respiratory infections are the leading cause of morbidity and mortality in children with cystic fibrosis. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which predisposes these children to recurrent respiratory infections. Malnutrition and diabetes are common comorbidities in cystic fibrosis but are not the leading causes of morbidity and mortality in affected children. Liver disease can occur in cystic fibrosis but is less common than respiratory complications.

5. Which of the following is the best indicator of a child's nutritional status?

• A. Weight
• B. Height
• C. Head circumference
• D. Mid-upper arm circumference

Correct answer: D

Rationale: Mid-upper arm circumference is a good indicator of muscle mass and fat stores, reflecting a child's nutritional status. It is particularly useful in assessing malnutrition, as it is less affected by fluid retention or dehydration compared to other anthropometric measurements. Weight can fluctuate due to factors like hydration status, making it less reliable as a sole indicator of nutritional status. Height reflects growth but may not directly indicate current nutritional status. Head circumference is more related to brain growth and development rather than overall nutritional status.
