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. The nurse is caring for a child receiving chemotherapy with the following orders: Zantac 70 mg IV in normal saline 30 mL to infuse over 30 minutes. The nurse should set the infusion pump to deliver how many mL/hour?

• A. 60 mL/hour
• B. 45 mL/hour
• C. 30 mL/hour
• D. 15 mL/hour

Correct answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.

3. During examination of a toddler's extremities, the nurse notes that the child is bowlegged. The nurse should recognize that this finding is which?

• A. Abnormal and requires further investigation
• B. Abnormal unless it occurs in conjunction with knock-knee
• C. Normal if the condition is unilateral or asymmetric
• D. Normal because the lower back and leg muscles are not yet well developed

Correct answer: D

Rationale: Bowleggedness is normal in toddlers due to the development of lower back and leg muscles. It usually resolves as the child grows.

4. What is the most common cause of acute gastroenteritis in children under 5 years?

• A. Salmonella
• B. Rotavirus
• C. Norovirus
• D. Shigella

Correct answer: B

Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.

5. What urine test result is considered abnormal?

• A. pH 4.0
• B. WBC 1 or 2 cells/ml
• C. Protein level absent
• D. Specific gravity 1.020

Correct answer: A

Rationale: A urine pH of 4.0 is abnormally low, indicating possible acidosis or other metabolic conditions. WBC count of 1-2 cells/ml, absence of protein, and a specific gravity of 1.020 are within normal limits.
