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. Examination of the abdomen is performed correctly by the nurse in which order?

• A. Inspection, palpation, percussion, and auscultation
• B. Inspection, percussion, auscultation, and palpation
• C. Palpation, percussion, auscultation, and inspection
• D. Inspection, auscultation, percussion, and palpation

Correct answer: D

Rationale: The correct order for abdominal examination is inspection, auscult

3. What is the most critical physiologic change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.

4. Which parental statement indicates correct understanding regarding pancreatic enzyme administration in the treatment of cystic fibrosis?

• A. “I will administer this medication 4 times a day.”
• B. “I will administer this medication twice a day.”
• C. “I will administer this medication with meals and snacks.”
• D. “I will administer this medication every 6 hours with meals.”

Correct answer: C

Rationale: The correct answer is C: "I will administer this medication with meals and snacks." Pancreatic enzymes should be administered with meals and snacks to aid in the digestion of nutrients in children with cystic fibrosis. Choices A, B, and D are incorrect because administering the medication without meals and snacks may not provide the necessary support for digestion needed in cystic fibrosis.

5. Why does the nurse have a 2-year-old boy sit in a “tailor” position while palpating for the presence of the testes?

• A. It prevents the cremasteric reflex
• B. Undescended testes can be palpated
• C. The child has an inguinal hernia
• D. The child does not yet have a need for privacy

Correct answer: A

Rationale: The tailor position stretches the muscle responsible for the cremasteric reflex, preventing it from contracting and pulling the testes into the pelvic cavity. This position helps accurately palpate the testes. Choice B is incorrect because the position does not facilitate the palpation of undescended testes specifically. Choice C is incorrect as it does not relate to the rationale behind the tailor position. Choice D is incorrect as the reason for using the tailor position is not related to the child's need for privacy.
