Nursing Elites

1. A child with acute gastrointestinal bleeding is admitted to the hospital. The nurse observes which sign or symptom as an early manifestation of shock?

• A. Restlessness
• B. Rapid capillary refill
• C. Increased temperature
• D. Increased blood pressure

Correct answer: A

Rationale: Restlessness is an early sign of shock due to decreased perfusion and oxygenation to the brain. This symptom requires immediate attention to prevent the progression to more severe stages of shock. Rapid capillary refill (Choice B) is not typically an early sign of shock but rather a sign of adequate perfusion. Increased temperature (Choice C) may occur in later stages of shock due to the body's response to stress. Increased blood pressure (Choice D) is not an early sign of shock; in fact, blood pressure tends to decrease in shock as a compensatory mechanism.

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. The nurse is caring for a child with acute postinfectious glomerulonephritis. Which of the following best describes the pathophysiology of acute postinfectious glomerulonephritis?

• A. Occurs after a urinary tract infection
• B. Occurs after a streptococcal infection
• C. Associated with renal vascular disorders
• D. Is caused by E. coli

Correct answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body’s immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.

4. When assessing a preschooler's chest, what should the nurse expect?

• A. Respiratory movements to be chiefly thoracic
• B. Anteroposterior diameter to be equal to the transverse diameter
• C. Retraction of the muscles between the ribs on respiratory movement
• D. Movement of the chest wall to be symmetric bilaterally and coordinated with breathing

Correct answer: D

Rationale: In a preschooler, chest movement should be symmetric and coordinated with breathing, indicating healthy respiratory function.

5. Rectal temperatures are indicated in which situation?

• A. In the newborn period
• B. Whenever accuracy is essential
• C. Rectal temperatures are never indicated
• D. When rapid temperature changes are occurring

Correct answer: B

Rationale: Rectal temperatures provide the most accurate measurement of core body temperature and are therefore indicated when accuracy is essential.
