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. At what age is the first dose of the hepatitis A vaccine recommended to be started?

• A. 1 year
• B. 1 month
• C. 12 years
• D. It is not recommended at any age

Correct answer: A

Rationale: The correct answer is A: 1 year. The hepatitis A vaccine is now recommended for all children starting at age 1 year (i.e., 12 to 23 months). This is due to the recognition of hepatitis A as a significant child health problem, especially in areas with high infection rates. The virus is primarily spread through fecal-oral transmission, person-to-person contact, ingestion of contaminated food or water, and rarely through blood transfusion. Administering the first dose at 1 year helps protect children from this infection. Choices B and C are incorrect as the vaccine is not recommended at 1 month or 12 years. Choice D is also incorrect as the hepatitis A vaccine is recommended at a specific age to prevent the infection.

3. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:

• A. Teratogens
• B. Heterozygous
• C. Inborn errors
• D. Multifactorial

Correct answer: A

Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.

4. When teaching a mother how to administer eye drops, where should the nurse tell her to place them?

• A. At the lacrimal duct
• B. On the sclera while the child looks to the outside
• C. In the conjunctival sac when the lower eyelid is pulled down
• D. Carefully under the eyelid while it is gently pulled upward

Correct answer: C

Rationale: Eye drops should be placed in the conjunctival sac, which allows the medication to be absorbed properly without causing irritation. Placing drops directly on the sclera or near the lacrimal duct is less effective and can cause discomfort.

5. The nurse should assess which age group for suicide ideation since suicide in which age group is the third leading cause of death?

• A. Preschoolers
• B. Young school age
• C. Middle school age
• D. Late school age and adolescents

Correct answer: D

Rationale: Suicide is the third leading cause of death in late school-age children and adolescents, requiring careful assessment for ideation in these age groups.
