Nursing Elites

1. The nurse is admitting a child with severe isotonic dehydration. Which intravenous fluid should the nurse anticipate the doctor to order initially to replace fluids?

• A. 0.9% normal saline
• B. D5 0.2% (1/4) normal saline
• C. D5W
• D. Albumin

Correct answer: A

Rationale: In the case of severe isotonic dehydration, the initial fluid of choice is 0.9% normal saline. This solution is preferred because it helps to restore both fluids and electrolytes effectively. Options B, C, and D are not suitable for the initial management of severe isotonic dehydration. D5 0.2% (1/4) normal saline (Choice B) is a hypotonic solution and might worsen the imbalance. D5W (Choice C) is a hypotonic solution that does not contain electrolytes essential for rehydration. Albumin (Choice D) is a colloid solution used for specific indications like hypoproteinemia or hypoalbuminemia, not for initial rehydration in severe dehydration.

2. Which one of the following strategies might be recommended for an infant with failure to thrive (FTT) to increase caloric intake?

• A. Vary the schedule for routine activities on a daily basis.
• B. Be persistent through 10 to 15 minutes of food refusal.
• C. Avoid solids until after the bottle is well accepted.
• D. Use developmental stimulation by a specialist during feedings.

Correct answer: B

Rationale: Being persistent through 10 to 15 minutes of food refusal is recommended to help increase caloric intake in infants with FTT. Establishing a routine and using developmental stimulation can also be helpful, but the priority is ensuring adequate caloric intake.

3. When should a child receive the first dose of the hepatitis B virus (HBV) vaccine if the mother is hepatitis B surface antigen (HBsAg) negative?

• A. 2 months of age, before hospital discharge.
• B. Birth before discharge from the hospital.
• C. 6 months of age, at the third well-child visit.
• D. No time (this vaccine is not currently recommended).

Correct answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.

4. Which explains the importance of detecting strabismus in young children?

• A. Color vision deficit may result.
• B. Amblyopia, a type of blindness, may result.
• C. Epicanthal folds may develop in the affected eye
• D. Corneal light reflexes may fall symmetrically within each pupil

Correct answer: B

Rationale: Undetected strabismus can lead to amblyopia, where the brain favors one eye over the other, potentially resulting in permanent vision loss in the affected eye.

5. The nurse is evaluating research studies according to the GRADE criteria and has determined the quality of evidence on the subject is moderate. Which type of evidence does this determination indicate?

• A. Strong evidence from unbiased observational studies
• B. Evidence from randomized clinical trials showed inconsistent results
• C. Consistent evidence from well-performed randomized clinical trials
• D. Evidence for at least one critical outcome from randomized clinical trials had serious flaws

Correct answer: B

Rationale: Moderate evidence typically indicates that results from randomized clinical trials were inconsistent, highlighting the need for further research to confirm findings.
