Nursing Elites

1. The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?

• A. Maternally derived iron stores are depleted in the first 2 months.
• B. Fetal hemoglobin results in a shortened survival of red blood cells.
• C. The production of adult hemoglobin decreases in the first year of life.
• D. Low levels of fetal hemoglobin depress the production of erythropoietin.

Correct answer: B

Rationale: Physiologic anemia is caused by the transition from fetal to adult hemoglobin, with fetal hemoglobin having a shorter lifespan, leading to a temporary decrease in red blood cells.

2. 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.

3. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.

4. The nurse is performing an assessment on a 10-week-old infant. The nurse understands that the developmental characteristic of hearing at this age is which?

• A. The infant responds to his own name.
• B. The infant localizes sounds by turning his head directly to the sound.
• C. The infant turns his head to the side when sound is made at the level of the ear.
• D. The infant locates sound by turning his head to the side and then looking up or down.

Correct answer: C

Rationale: By 10 weeks, infants typically turn their heads to the side to locate the source of a sound made at ear level.

5. The nurse is seeing an adolescent and the parents in the clinic for the first time. Which should the nurse do first?

• A. Introduce him- or herself
• B. Make the family comfortable
• C. Give assurance of privacy
