Nursing Elites

1. Which explains the importance of detecting strabismus in young children?

• A. Color vision deficit may result.
• B. Amblyopia, a type of blindness, may result.
• C. Epicanthal folds may develop in the affected eye
• D. Corneal light reflexes may fall symmetrically within each pupil

Correct answer: B

Rationale: Undetected strabismus can lead to amblyopia, where the brain favors one eye over the other, potentially resulting in permanent vision loss in the affected eye.

2. What is the most common cause of acute gastroenteritis in children under 5 years?

• A. Salmonella
• B. Rotavirus
• C. Norovirus
• D. Shigella

Correct answer: B

Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.

3. The school nurse is explaining to older school children that obesity increases the risk for which disorders? (Select all that apply.)

• A. Asthma
• B. Hypertension
• C. Dyslipidemia
• D. All of the above

Correct answer: D

Rationale: Obesity increases the risk for conditions like asthma, hypertension, dyslipidemia, and altered glucose metabolism, but not typically irritable bowel disease.

4. The nurse notes that a child has lost 3.6 kg (8 lb) after 4 days of hospitalization for acute glomerulonephritis. What is the most likely cause of this weight loss?

• A. Poor appetite
• B. Reduction of edema
• C. Restriction to bed rest
• D. Increased potassium intake

Correct answer: B

Rationale: The weight loss is most likely due to the reduction of edema, as glomerulonephritis often causes fluid retention that resolves with treatment, leading to significant weight loss.

5. 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.
