Nursing Elites

1. During an otoscopic examination on an infant, in which direction is the pinna pulled?

• A. Up and back
• B. Up and forward
• C. Down and back
• D. Down and forward

Correct answer: C

Rationale: For infants, the pinna is pulled down and back to straighten the ear canal and allow proper visualization of the tympanic membrane during otoscopic examination.

2. The nurse is caring for a child with sickle cell anemia with the following order: Morphine Sulfate 2 mg IV every 24 hours. Morphine Sulfate is available in 10 mg/1mL. How many mL should the nurse administer?

• A. 0.2 mL
• B. 0.5 mL
• C. 1 mL
• D. 2 mL

Correct answer: A

Rationale: To administer 2 mg of Morphine Sulfate when the concentration is 10 mg/mL, the nurse should administer 0.2 mL (2 mg / 10 mg/mL = 0.2 mL). Choice B, 0.5 mL, is incorrect because it is the result of dividing 2 mg by 4 mg/mL instead of 10 mg/mL. Choice C, 1 mL, is incorrect as it would be the result of dividing 2 mg by 2 mg/mL. Choice D, 2 mL, is incorrect as it would be the result of dividing 2 mg by 1 mg/mL.

3. What is the primary symptom of congenital diaphragmatic hernia in a newborn?

• A. Cyanosis
• B. Bradycardia
• C. Absent breath sounds
• D. Tachypnea

Correct answer: C

Rationale: Absent breath sounds on the affected side are a primary symptom of congenital diaphragmatic hernia. Cyanosis, bradycardia, and tachypnea may also be present but are not the primary symptom. Cyanosis is a bluish discoloration of the skin due to poor oxygenation, bradycardia is a slower than normal heart rate, and tachypnea is rapid breathing.

4. 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.

5. A mother delivers an infant at 30 weeks gestation and asks if formula is better than breast milk since the baby is premature. What should the nurse respond?

• A. Human milk is preferred over other types of nutrition
• B. Human milk lacks essential nutrients for preterm infants
• C. Commercial infant formulas are preferred for preterm infants
• D. Commercial formulas have not been designed to meet preterm infants' needs

Correct answer: A

Rationale: Human milk is preferred, even for preterm infants, because it contains essential nutrients and antibodies that are particularly beneficial for their growth and development. Choice B is incorrect because human milk is rich in essential nutrients necessary for preterm infants. Choice C is incorrect as commercial infant formulas do not provide the same benefits as human milk. Choice D is incorrect as specialized formulas are available to meet the unique nutritional needs of preterm infants, but human milk remains the optimal choice.
