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. The nurse is assessing a child's capillary refill time. This can be accomplished by doing what?

• A. Inspect the chest
• B. Auscultate the heart
• C. Palpate the apical pulse
• D. Palpate the nail bed with pressure to produce a slight blanching

Correct answer: D

Rationale: Capillary refill time is assessed by applying pressure to the nail bed and observing how quickly the color returns, indicating peripheral circulation status.

3. What is the most effective way to prevent the spread of hand, foot, and mouth disease in a daycare setting?

• A. Handwashing
• B. Isolating sick children
• C. Disinfecting toys
• D. Encouraging vaccination

Correct answer: A

Rationale: Handwashing is indeed the most effective way to prevent the spread of hand, foot, and mouth disease in children. Proper hand hygiene helps in removing and killing germs that can cause infections. While isolating sick children and disinfecting toys are important measures to prevent the spread of diseases, they are not as effective as handwashing. Encouraging vaccination, in this case, is not relevant since there is no specific vaccine available for hand, foot, and mouth disease.

4. An infant is brought to the emergency department with the following clinical manifestations: poor skin turgor, weight loss, lethargy, tachycardia, and tachypnea. This is suggestive of which situation?

• A. Water excess
• B. Sodium excess
• C. Water depletion
• D. Potassium excess

Correct answer: C

Rationale: These symptoms are indicative of dehydration or water depletion, which is common in infants and can rapidly lead to severe consequences if not addressed promptly.

5. When checking the intravenous (IV) site on a child, the nurse should take which action?

• A. Look at the site.
• B. Ask the child if the site hurts.
• C. Look at the site while palpating the area.
• D. Take all the tape off, assess the site, and redress.

Correct answer: C

Rationale: Looking at and palpating the IV site helps assess for signs of infiltration or infection, such as swelling, redness, or pain. Simply looking or asking the child may miss subtle signs, and removing all the tape unnecessarily disrupts the site.
