The student nurse is collecting data on a child diagnosed with cystic fibrosis and notes the child has a barrel chest and clubbing of the fingers. In explaining this manifestation of the disease, the staff nurse explains the cause of this symptom to be:

high sodium chloride concentration in the sweat.

chronic lack of oxygen.

decreased respiratory capacity.

impaired digestive activity.

Answer and Explanation

The Correct Answer is B

A. While cystic fibrosis is characterized by a high concentration of sodium chloride in sweat due to defective chloride channels, this is not the cause of the barrel chest and clubbing of the fingers.

B. The barrel chest and clubbing of the fingers are often seen in children with cystic fibrosis due to chronic hypoxia (lack of oxygen). Chronic lung infections, airway obstruction, and respiratory insufficiency associated with cystic fibrosis lead to prolonged low oxygen levels, which can result in these physical changes.

C. Decreased respiratory capacity, often due to the chronic respiratory issues associated with cystic fibrosis, can result in a barrel chest (increased chest diameter due to air trapping) and clubbing of the fingers (a sign of chronic hypoxia).

D. Decreased respiratory capacity (due to thick mucus and airway obstruction) does contribute to chronic respiratory issues in cystic fibrosis, but the direct cause of the barrel chest and clubbing is the chronic lack of oxygen (hypoxia) rather than decreased capacity alone. The changes in the chest and fingers are a result of prolonged oxygen deprivation.

Correct Answer is ["25"]

Explanation

To calculate the drops per minute for an IV infusion, we need to use the following formula:

gtt/min = (volume x drop factor) / time

In this case, the volume is 50 mL, the drop factor is 20 gtt/mL, and the time is 40 minutes. Plugging these values into the formula, we get:

gtt/min = (50 x 20) / 40

gtt/min = 1000 / 40

gtt/min = 25

Therefore, the adolescent patient should receive 25 drops per minute of Cefazolin IV.

A. Haemophilus influenza type b (Hib) B. Varicella (VAR) C. Measles, Mumps, and Rubella (MMR) D. Meningococcal (MCV4) E. Hepatitis B (Hep B):
