Nursing Elites

1. 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.

2. Pertussis vaccination should begin at which age?

• A. Birth
• B. 2 months
• C. 6 months
• D. 12 months

Correct answer: B

Rationale: The DTaP vaccine, which includes pertussis, is typically started at 2 months of age as part of the recommended immunization schedule.

3. In teaching parents about appropriate pacifier selection, the nurse should recommend which characteristic?

• A. Easily grasped handle
• B. Detachable shield for cleaning
• C. Soft, pliable material
• D. Ribbon or string to secure to clothing

Correct answer: A

Rationale: A pacifier with an easily grasped handle is safer and more convenient for the infant to use without the risk of choking hazards that detachable parts might pose.

4. What is the most appropriate intervention for a child with suspected acute appendicitis?

• A. Administer antibiotics
• B. Apply heat to the abdomen
• C. Encourage oral fluids
• D. Prepare for surgery

Correct answer: D

Rationale: The correct answer is D: Prepare for surgery. Acute appendicitis is a surgical emergency that requires prompt removal of the appendix to prevent complications like rupture and peritonitis. Administering antibiotics (choice A) may be part of the treatment plan but should not delay surgical intervention. Applying heat to the abdomen (choice B) is not recommended as it can worsen the inflammation of the appendix. Encouraging oral fluids (choice C) is generally beneficial, but the priority in acute appendicitis is surgical intervention.

5. Which explains the importance of detecting strabismus in young children?

• A. Color vision deficit may result.
• B. Amblyopia, a type of blindness, may result.
• C. Epicanthal folds may develop in the affected eye
• D. Corneal light reflexes may fall symmetrically within each pupil

Correct answer: B

Rationale: Undetected strabismus can lead to amblyopia, where the brain favors one eye over the other, potentially resulting in permanent vision loss in the affected eye.
