Nursing Elites

1. The nurse is teaching parents about diarrhea in young children. A parent asks the nurse what causes most cases of diarrhea in young children. How should the nurse respond?

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

Correct answer: A

Rationale: Rotavirus is the most common cause of diarrhea in young children, particularly those under the age of 2. Giardia, Shigella, and Salmonella can also cause diarrhea, but in the context of young children, Rotavirus is the primary pathogen responsible for diarrheal illnesses.

2. Following treatment for iron deficiency anemia, the physician orders lab tests. Which lab value would indicate an improvement in the child’s condition?

• A. Low hemoglobin
• B. Normal platelet count
• C. High reticulocyte count
• D. Low hematocrit

Correct answer: C

Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.

3. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

4. What information should be given to the parents of a 12-month-old child regarding appropriate play activities for this age?

• A. Give large push-pull toys for kinetic stimulation
• B. Place a cradle gym across the crib to help develop fine motor skills
• C. Provide the child with finger paints to enhance fine motor skills
• D. Provide a stick horse to develop gross motor coordination

Correct answer: A

Rationale: Large push-pull toys are suitable for a 12-month-old as they encourage gross motor skills and physical activity, which are crucial for their development at this age.

5. Urinary tract anomalies are frequently associated with what irregularities in fetal development?

• A. Myelomeningocele
• B. Cardiovascular anomalies
• C. Malformed or low-set ears
• D. Defects in lower extremities

Correct answer: C

Rationale: Malformed or low-set ears are often associated with congenital urinary tract anomalies, as both the ears and kidneys develop around the same time during fetal growth. Myelomeningocele, cardiovascular anomalies, and lower extremity defects are less commonly associated with UT anomalies.
