Nursing Elites

1. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.

2. A 12-month-old child presents to the clinic for a well visit after missing several appointments. The child began her immunization schedule but has missed several follow-up appointments and doses of immunizations. What is the most appropriate nursing intervention?

• A. Administer initial immunizations from the beginning of the schedule.
• B. The child cannot receive missed immunizations if the schedule is not followed and will not be vaccinated.
• C. The child should only receive the missed doses of immunizations based on the catch-up schedule.
• D. The child should receive double-strength immunizations at this well visit.

Correct answer: C

Rationale: Children who began primary immunization at the recommended age but fail to receive all the doses do not need to begin the series again but should receive only the missed doses. The child may receive missed vaccinations on a catch-up schedule per CDC guidelines.

3. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?

• A. Neurogenic shock
• B. Cardiogenic shock
• C. Hypovolemic shock
• D. Anaphylactic shock

Correct answer: D

Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.

4. At which age should the nurse expect an infant to begin smiling in response to pleasurable stimuli?

• A. 1 month
• B. 2 months
• C. 3 months
• D. 4 months

Correct answer: B

Rationale: Infants typically begin to smile in response to pleasurable stimuli by 2 months, which is an early sign of social interaction and emotional development.

5. A child is admitted with acute glomerulonephritis. What should the nurse expect the urinalysis during this acute phase to show?

• A. Bacteriuria and hematuria
• B. Hematuria and proteinuria
• C. Bacteriuria and increased specific gravity
• D. Proteinuria and decreased specific gravity

Correct answer: B

Rationale: Hematuria (blood in the urine) and proteinuria (protein in the urine) are common findings in acute glomerulonephritis due to inflammation of the glomeruli. Bacteriuria and changes in specific gravity are not as directly associated with this condition.
