Nursing Elites

1. The parents of a newborn with an umbilical hernia ask about treatment options. The nurse's response should be based on which knowledge?

• A. Surgery is recommended as soon as possible.
• B. The defect usually resolves spontaneously by 3 to 5 years of age.
• C. Aggressive treatment is necessary to reduce its high mortality.
• D. Taping the abdomen to flatten the protrusion is not recommended.

Correct answer: B

Rationale: The correct answer is B. Most umbilical hernias in newborns resolve on their own by 3 to 5 years of age without the need for surgical intervention, unless complications arise. Surgery is not typically recommended for umbilical hernias in newborns due to the high rate of spontaneous resolution. Aggressive treatment is not necessary as umbilical hernias are typically benign and not associated with high mortality. Taping the abdomen is not recommended as it can cause skin irritation and does not speed up the resolution of the hernia.

2. What is a physical characteristic of infants whose mothers smoked during pregnancy?

• A. Being large for gestational age
• B. Growth restriction in weight only
• C. Preterm but size appropriate for gestational age
• D. Growth restriction in weight, length, and chest and head circumference

Correct answer: D

Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.

3. Which developmental milestone would the nurse expect an 11-month-old infant to have achieved?

• A. Sitting independently
• B. Turning a doorknob
• C. Building a tower of four cubes
• D. Walking independently

Correct answer: A

Rationale: The correct answer is A: Sitting independently. By 11 months, most infants can sit independently. This milestone usually precedes walking, which typically occurs closer to 12 months. Turning a doorknob and building a tower of four cubes involve more complex motor skills that are typically achieved later in development. Therefore, at 11 months, sitting independently is the milestone that the nurse would expect an infant to have achieved.

4. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?

• A. Gently tap over the site.
• B. Apply a cold compress to the site.
• C. Raise the extremity above the level of the body
• D. Use a rubber band as a tourniquet for 5 minutes.

Correct answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

5. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.
