Nursing Elites

1. Which electrolyte imbalance is a common concern in children with severe diarrhea?

• A. Hypernatremia
• B. Hypokalemia
• C. Hypercalcemia
• D. Hypomagnesemia

Correct answer: B

Rationale: Hypokalemia is the correct answer because it is a common concern in children with severe diarrhea. Diarrhea can lead to significant potassium loss, resulting in hypokalemia. Hypernatremia (Choice A) is less common in diarrhea as sodium concentration is usually diluted by the fluid loss. Hypercalcemia (Choice C) is not typically associated with severe diarrhea. Hypomagnesemia (Choice D) can occur but is not as common as hypokalemia in this scenario.

2. What is the leading cause of morbidity and mortality in children with cystic fibrosis?

• A. Respiratory infections
• B. Malnutrition
• C. Diabetes
• D. Liver disease

Correct answer: A

Rationale: Respiratory infections are the leading cause of morbidity and mortality in children with cystic fibrosis. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which predisposes these children to recurrent respiratory infections. Malnutrition and diabetes are common comorbidities in cystic fibrosis but are not the leading causes of morbidity and mortality in affected children. Liver disease can occur in cystic fibrosis but is less common than respiratory complications.

3. The nurse is preparing to admit a child to the hospital with a diagnosis of acute poststreptococcal glomerulonephritis. The nurse understands that the peak age at onset for this disease is what?

• A. 2 to 4 years
• B. 5 to 7 years
• C. 8 to 10 years
• D. 11 to 13 years

Correct answer: B

Rationale: The peak age for the onset of acute poststreptococcal glomerulonephritis is typically between 5 and 7 years old. This age group is most affected due to the higher incidence of streptococcal infections in school-aged children, which can lead to this renal complication.

4. During a well-child checkup, the parent of a 5-year-old child reports the child seems much smaller than the 2 older siblings did at this same age. A review of the medical record reveals that the child is 44 inches tall and weighs 42 pounds. What information should be included in the response by the nurse?

• A. The weight of your child at this time is within normal limits for this age but the child is moderately taller than other children this age.
• B. Your child is within the acceptable range for height but the child is significantly smaller in weight for this age.
• C. Your child is within normal limits for weight but the child is slightly shorter in stature than other children this age.
• D. Your child is slightly taller than other children this age but the child’s weight is normal.

Correct answer: D

Rationale: The correct answer is D. The child is slightly taller than average, but the weight is within normal limits. This information should be reassuring to the parent and provides insights into normal growth patterns. Choice A is incorrect as it inaccurately states that the child is taller than other children this age. Choice B is incorrect because the child's weight is actually within normal limits. Choice C is incorrect as it inaccurately states that the child is shorter in stature than other children this age.

5. The LPN is caring for a 1-month-old patient post-surgery. Which pain scale is expected to be used to evaluate post-op pain?

• A. Oucher
• B. Wong-Baker FACES
• C. FLACC
• D. 0-10 pain scale

Correct answer: C

Rationale: The FLACC (Face, Legs, Activity, Cry, Consolability) scale is commonly used to assess pain in infants and young children who are unable to verbally communicate their pain. This scale is particularly useful in assessing post-operative pain in infants as it evaluates different behaviors and physiological responses to pain. The Oucher scale is more commonly used with children who are older and can provide self-report of pain intensity. Wong-Baker FACES scale is primarily used with children who are older and can indicate their pain level by pointing to facial expressions. The 0-10 pain scale is typically used with older children and adults who can rate their pain on a numerical scale.
