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. Children are taught the values of their culture through observation and feedback relative to their own behavior. In teaching a class on cultural competence, the nurse should be aware that which factor may be culturally determined?

• A. Ethnicity
• B. Racial variation
• C. Status
• D. Geographic boundaries

Correct answer: C

Rationale: Status, or the social standing within a culture, is often culturally determined and plays a significant role in shaping behaviors and expectations.

3. Which condition is characterized by a harsh, barking cough in children?

• A. Asthma
• B. Bronchiolitis
• C. Croup
• D. Pneumonia

Correct answer: C

Rationale: Croup is the correct answer. It is characterized by a harsh, barking cough due to inflammation of the upper airways, specifically the larynx and trachea. Asthma (Choice A) often presents with wheezing and shortness of breath, not a barking cough. Bronchiolitis (Choice B) typically causes wheezing and respiratory distress in infants. Pneumonia (Choice D) manifests with symptoms such as fever, productive cough, and chest pain, but not usually a barking cough.

4. 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.

5. What is often the initial sign of acute rheumatic fever in children?

• A. Polyarthritis
• B. Carditis
• C. Erythema marginatum
• D. Sydenham chorea

Correct answer: A

Rationale: Polyarthritis is indeed frequently the initial sign of acute rheumatic fever in children. It presents as joint pain, swelling, and redness. Carditis (inflammation of the heart), Erythema marginatum (a skin rash), and Sydenham chorea (involuntary muscle movements) are typically seen in the later stages of acute rheumatic fever and not as the initial sign.
