ATI Nursing Care of Children
1. The parents of a child with sickle cell anemia ask why their child did not have a sickle cell crisis until he was approximately 6 months old. How should the nurse respond?
- A. Your child probably had a crisis, and you were unaware of the symptoms.
- B. Are you sure your child has sickle cell anemia and not sickle cell trait?
- C. Affected children can be asymptomatic in early infancy because of high levels of fetal hemoglobin that inhibit sickling.
- D. Have you asked your doctor about this yet?
Correct answer: C
Rationale: The correct answer is C. Fetal hemoglobin (HbF) is present in high levels during early infancy, inhibiting sickling unlike adult hemoglobin (HbS). As the levels of HbF decrease and HbS increases, the risk of sickling and crises becomes more pronounced, typically after 6 months of age. Choice A is incorrect because it assumes the crisis went unnoticed, which is not supported by medical knowledge. Choice B is incorrect as it questions the child's diagnosis rather than explaining the phenomenon of delayed crises. Choice D is incorrect as it does not provide the parents with the necessary information regarding their query.
2. Melena, the passage of black, tarry stools, suggests bleeding from which source?
- A. The perianal or rectal area
- B. The upper gastrointestinal (GI) tract
- C. The lower GI tract
- D. Hemorrhoids or anal fissures
Correct answer: B
Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.
3. 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.
4. What is the required number of milliliters of fluid needed per day for a 14-kg child?
- A. 800
- B. 1000
- C. 1200
- D. 1400
Correct answer: D
Rationale: The fluid requirement for a 14-kg child is approximately 100 mL/kg/day, so for a 14-kg child, the requirement is around 1400 mL/day.
5. What does the Hib conjugate vaccine protect against?
- A. Bacterial meningitis
- B. Epiglottitis
- C. Bacterial pneumonia
- D. All Correct
Correct answer: D
Rationale: The Hib conjugate vaccine is crucial for protecting children from several severe infections caused by Haemophilus influenzae type b, including bacterial meningitis, epiglottitis, bacterial pneumonia, septic arthritis, and sepsis. Therefore, all the provided options are correct. Bacterial meningitis, epiglottitis, and bacterial pneumonia are serious conditions that the Hib vaccine effectively prevents, making choice D the correct answer. Choices A, B, and C are incorrect when considered individually as the Hib vaccine does not protect against only one specific infection; rather, it provides immunity against multiple diseases caused by Haemophilus influenzae type b.
