Match the drug Digoxin to the correct classification?

A. Both parents are carriers of the CF gene: Cystic fibrosis follows an autosomal recessive inheritance pattern, meaning both parents must carry one copy of the defective gene, even if they do not have the disease themselves. The child inherits one copy of the defective gene from each parent to develop CF.

B. The inheritance pattern is multifactorial: CF is not a multifactorial disease; it follows a clear recessive genetic inheritance pattern.

C. The result is probably a genetic mutation: CF is caused by a genetic mutation, but this mutation is inherited from both parents. It is not usually a spontaneous mutation unless it occurs in the parental genetic material, which is rare.

D. Only one parent carries the CF gene: For the child to inherit CF, both parents must be carriers of the gene. If only one parent carries the gene, the child would be a carrier, not affected by the disease.

1. A. Provide oxygen at 6 L/min via nasal cannula: Oxygen is only used if the patient has hypoxemia (O2 saturation below 92%), which is not indicated in this scenario.
   B. Perform passive ROM exercises: Not appropriate during a sickle cell crisis due to the risk of exacerbating pain.
   C. Administer IV fluids: Essential to reduce blood viscosity and prevent further sickling.
   D. Obtain consent for a blood transfusion: Necessary in severe anemia (e.g., hemoglobin of 5 g/dL).
   E. Restrict fluid intake to 1,400 mL/day: Fluid restriction is contraindicated; hydration is key to management.
   F. Administer meperidine IV: Meperidine is generally avoided due to the risk of neurotoxicity; other opioids (e.g., morphine) are preferred.
   G. Encourage bedrest: Reduces oxygen demand during a crisis.
