A nurse is reviewing the medical record of a school-age child who has cystic fibrosis. Which of the following findings should the nurse report to the provider?
Heart rate.
WBC count.
HbA1c.
Oxygen saturation.
The Correct Answer is D
Answer is D. Oxygen saturation. The nurse should report the low oxygen saturation of 92% on room air to the provider, as this indicates hypoxemia and respiratory distress in a child with cystic fibrosis. The normal range for oxygen saturation is 95% to 100%¹. Hypoxemia can lead to complications such as pulmonary hypertension, cor pulmonale, and respiratory failure².
A. Heart rate is not the correct answer. The heart rate of 98 beats/min is normal high, but not alarming for a child with cystic fibrosis. The normal range for heart rate in school-age children is 60 to 100 beats/min³. A higher heart rate may be due to fever, infection, dehydration, or anxiety⁴.
B. WBC count is not the correct answer. The WBC count of 10,000/mm3 is within the normal range of 5,000 to 10,000/mm3⁵. A high WBC count may indicate infection or inflammation, which are common in cystic fibrosis⁶.
C. HbA1c is not the correct answer. The HbA1c of 6.5% is borderline for diabetes, but not an urgent finding. The normal range for HbA1c is 4% to 5.6%, and a level of 6.5% or higher indicates diabetes⁷. Cystic fibrosis-related diabetes (CFRD) is a common complication of cystic fibrosis, affecting about 30% of adults with the condition⁸. CFRD requires regular monitoring and treatment with insulin⁹..

Correct Answer is C
Explanation
Choice A rationale:
A blood pressure of 95/56 mm Hg is within the normal range for a 5-year-old child. While assessing vital signs, the nurse should consider the patient's age-specific parameters. In this case, the blood pressure is not indicative of hemorrhage.
Choice B rationale:
Flushing of the face might be a common postoperative finding and is not necessarily indicative of hemorrhage. It can be caused by various factors such as anesthesia or emotional states. Flushing alone is not a reliable sign of hemorrhage and should be assessed in conjunction with other symptoms.
Choice C rationale:
Continuous swallowing, especially with an increased heart rate and signs of restlessness, can be indicative of hemorrhage after a tonsillectomy and adenoidectomy. Frequent swallowing suggests the presence of blood in the mouth or throat, indicating possible bleeding at the surgical site. This finding requires immediate attention and intervention by the nurse.
Choice D rationale:
A heart rate of 54/min is below the normal range for a 5-year-old child, which typically ranges from 70 to 120 beats per minute. While bradycardia can be a concern, the more specific and immediate indication of hemorrhage in this case is continuous swallowing, which signals active bleeding from the surgical site.
Correct Answer is C
Explanation
Choice A rationale:
"Consume 1,500 to 1,700 calories per day." This statement provides a specific calorie range suitable for most adolescents. It ensures they receive adequate energy to support their growth and daily activities. Adequate caloric intake is essential during adolescence to support proper physical and mental development.
Choice B rationale:
"Decrease your vitamin D intake once you start to menstruate." Menstruation does not affect the need for vitamin D intake. In fact, vitamin D is crucial for bone health, especially during adolescence when bones are still developing. Adolescents, including females, should maintain an appropriate level of vitamin D intake to support bone health and overall well-being.
Choice C rationale:
"Increase the amount of your dietary iron intake." During adolescence, especially for females, iron requirements increase due to menstrual losses. Iron is essential for the production of red blood cells and to prevent anemia. Adolescents, particularly females, should be educated about the importance of including iron-rich foods in their diet to meet their increased nutritional needs.
Choice D rationale:
"Limit your sodium intake to 3,000 milligrams per day." While limiting sodium intake is generally advisable for overall health, this statement does not specifically address the nutritional needs of adolescents. Adolescents need guidance on various aspects of nutrition, but limiting sodium intake should be part of a broader discussion about a balanced diet, rather than a singular focus during this educational session.
