A nurse is caring for a child who has an exacerbation of cystic fibrosis. Which of the following laboratory findings should the nurse report to the provider immediately?

Blood glucose 140 mg/dL

Serum sodium 156 mEq/L

RBC 3.2 million/ul

Oxygen saturation 85%

Answer and Explanation

The Correct Answer is D

D. An oxygen saturation level of 85% is significantly below the normal range and indicates hypoxemia (low blood oxygen levels). This finding is concerning, especially in a child with cystic fibrosis, which can lead to respiratory complications such as airway obstruction, infection, or mucus plugging.

A. A blood glucose level of 140 mg/dL is within the normal range for children, so this finding would not typically require immediate reporting to the provider.

B. A serum sodium level of 156 mEq/L is significantly elevated and above the normal range. However, hypoxia is the priority.

C. A red blood cell (RBC) count of 3.2 million/µL falls within the normal range for children, so this finding would not typically require immediate reporting to the provider.

Correct Answer is A

Explanation

A. Nausea and vomiting are potential adverse effects of digoxin in children. Digoxin is a medication commonly used to treat heart conditions, but it can cause gastrointestinal disturbances as a side effect. Nausea and vomiting may occur, especially if the child is receiving too high a dose of digoxin or if they are particularly sensitive to the medication.

B. Improved appetite would not typically indicate an adverse effect of digoxin. In fact, digoxin is not known to have a direct effect on appetite. If a child experienced an increase in appetite while taking digoxin, it would likely be unrelated to the medication or could be due to other factors.

C. Increased urine output would not typically indicate an adverse effect of digoxin. Digoxin is not a diuretic medication, so it would not directly cause increased urine output.

D. Digoxin is not commonly associated with bradycardia in children.

A. Extreme fatigue B. An airway obstruction C. The presence of dehydration D. The presence of pain

Correct Answer is B

Explanation

B. Leaning forward with the chin thrust out, often described as the "sniffing position," is a classic sign of airway obstruction, particularly in cases of epiglottitis. This positioning helps to maximize airway patency by opening the airway and reducing the risk of further obstruction.

A. Leaning forward with the chin thrust out is not typically associated with extreme fatigue. Instead, it is a specific positioning often seen in individuals with epiglottitis to help alleviate airway obstruction and facilitate breathing.

C. Leaning forward with the chin thrust out is not indicative of dehydration. Dehydration may present with other signs and symptoms such as dry mucous membranes, decreased urine output, sunken fontanelle (in infants), and poor skin turgor.

D. Pain may be present in a child with epiglottitis but leaning forward with the chin thrust out is not primarily indicative of pain. This positioning is primarily a compensatory mechanism to alleviate airway obstruction rather than a response to pain.
