Nursing Elites

1. What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?

• A. Infarction of renal vessels
• B. Immune complex formation and glomerular deposition
• C. Bacterial endotoxin deposition on and destruction of glomeruli
• D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Correct answer: B

Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

2. 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.

3. Which factor is most likely to cause a "brittle" diabetic state in a child with type 1 diabetes?

• A. Noncompliance with diet
• B. Insulin resistance
• C. Frequent infections
• D. Hypothyroidism

Correct answer: C

Rationale: Frequent infections can destabilize blood sugar levels, leading to a "brittle" diabetic state in children with type 1 diabetes. Infections increase metabolic demands and can result in significant blood glucose fluctuations, requiring careful monitoring and adjustment of insulin therapy. Noncompliance with diet may affect blood sugar control but is not the primary cause of a "brittle" state. Insulin resistance is more common in type 2 diabetes rather than type 1. Hypothyroidism can impact metabolism but is not directly linked to the development of a "brittle" diabetic state in type 1 diabetes.

4. The apnea monitor alarm sounds on a neonate for the third time during this shift. What is the priority action by the nurse?

• A. Provide tactile stimulation.
• B. Administer 100% oxygen.
• C. Investigate possible causes of a false alarm.
• D. Assess infant for color and presence of respirations.

Correct answer: D

Rationale: The priority action for the nurse when the apnea monitor alarm sounds on a neonate is to assess the infant for color and the presence of respirations. This initial assessment helps determine the infant's respiratory status and the need for immediate intervention. Providing tactile stimulation or administering oxygen should only be done after assessing the infant's respiratory status. Investigating possible causes of a false alarm comes after ensuring the infant's well-being through the initial assessment.

5. When auscultating an infant's lungs, the nurse detects diminished breath sounds. What should the nurse interpret this as?

• A. Suggestive of chronic pulmonary disease
• B. Suggestive of impending respiratory failure
• C. An abnormal finding warranting investigation
• D. A normal finding in infants younger than 1 year of age

Correct answer: C

Rationale: Diminished breath sounds in an infant are an abnormal finding and warrant further investigation to rule out conditions like atelectasis or pneumonia.
