Nursing Elites

1. The parents of a child with sickle cell anemia ask why their child did not have a sickle cell crisis until he was approximately 6 months old. How should the nurse respond?

• A. Your child probably had a crisis, and you were unaware of the symptoms.
• B. Are you sure your child has sickle cell anemia and not sickle cell trait?
• C. Affected children can be asymptomatic in early infancy because of high levels of fetal hemoglobin that inhibit sickling.
• D. Have you asked your doctor about this yet?

Correct answer: C

Rationale: The correct answer is C. Fetal hemoglobin (HbF) is present in high levels during early infancy, inhibiting sickling unlike adult hemoglobin (HbS). As the levels of HbF decrease and HbS increases, the risk of sickling and crises becomes more pronounced, typically after 6 months of age. Choice A is incorrect because it assumes the crisis went unnoticed, which is not supported by medical knowledge. Choice B is incorrect as it questions the child's diagnosis rather than explaining the phenomenon of delayed crises. Choice D is incorrect as it does not provide the parents with the necessary information regarding their query.

2. Which type of breath sound is normally heard over the entire surface of the lungs except for the upper intrascapular area and the area beneath the manubrium?

• A. Vesicular
• B. Bronchial
• C. Adventitious
• D. Bronchovesicular

Correct answer: A

Rationale: Vesicular breath sounds are normally heard over most of the lung fields, except near the trachea and main bronchi, where bronchial or bronchovesicular sounds may be heard.

3. The nurse is describing clinical reasoning to a group of nursing students. Which is most descriptive of clinical reasoning?

• A. Purposeful and goal-directed
• B. A simple developmental process
• C. Based on deliberate and irrational thought
• D. Assists individuals in guessing what is most appropriate

Correct answer: A

Rationale: Clinical reasoning is purposeful and goal-directed, involving the use of critical thinking and decision-making skills to provide effective patient care.

4. Which condition is characterized by a "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 distinctive "barking" cough, typically worse at night, caused by the inflammation of the upper airway, specifically the larynx and trachea. Asthma (Choice A) typically presents with wheezing and shortness of breath rather than a barking cough. Bronchiolitis (Choice B) commonly causes wheezing and respiratory distress in infants and young children. Pneumonia (Choice D) often presents with symptoms like fever, productive cough, and chest pain, but not typically a barking cough.

5. What diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?

• A. Renal ultrasonography
• B. Computed tomography
• C. Intravenous pyelography
• D. Voiding cystourethrography

Correct answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.
