Nursing Elites

1. The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?

• A. Maternally derived iron stores are depleted in the first 2 months.
• B. Fetal hemoglobin results in a shortened survival of red blood cells.
• C. The production of adult hemoglobin decreases in the first year of life.
• D. Low levels of fetal hemoglobin depress the production of erythropoietin.

Correct answer: B

Rationale: Physiologic anemia is caused by the transition from fetal to adult hemoglobin, with fetal hemoglobin having a shorter lifespan, leading to a temporary decrease in red blood cells.

2. 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.

3. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

4. The clinic nurse is reviewing statistics on infant mortality for the United States versus other countries. Compared with other countries that have a population of at least 25 million, the nurse makes which determination?

• A. The United States is ranked last among 27 countries
• B. The United States is ranked similar to 20 other developed countries
• C. The United States is ranked in the middle of 20 other developed countries
• D. The United States is ranked highest among 27 other industrialized countries

Correct answer: A

Rationale: The United States is ranked last among developed countries with similar populations in terms of infant mortality rates, highlighting a significant public health concern.

5. The nurse is aware that skin turgor best estimates what?

• A. Perfusion
• B. Adequate hydration
• C. Amount of body fat
• D. Amount of anemia

Correct answer: B

Rationale: Skin turgor is a quick and simple way to assess hydration status. Poor skin turgor can indicate dehydration.
