A nurse cares for a female client who has a family history of cystic fibrosis. The client asks, Will my children have cystic fibrosis? How should the nurse respond?
 
  a. Since many of your family members are carriers, your children will also be carriers of the gene.
  b. Cystic fibrosis is an autosomal recessive disorder. If you are a carrier, your children will have the disorder.
  c. Since you have a family history of cystic fibrosis, I would encourage you and your partner to be tested.
  d. Cystic fibrosis is caused by a protein that controls the movement of chloride. Adjusting your diet will decrease the spread of this disorder.

Question 2

A nurse administers medications to a client who has asthma. Which medication classification is paired correctly with its physiologic response to the medication?
 
  a. Bronchodilator - Stabilizes the membranes of mast cells and prevents the release of inflammatory mediators
  b. Cholinergic antagonist - Causes bronchodilation by inhibiting the parasympathetic nervous system
  c. Corticosteroid - Relaxes bronchiolar smooth muscles by binding to and activating pulmonary beta2 receptors
  d. Cromone - Disrupts the production of pathways of inflammatory mediators

Answer to Question 1

ANS: C
Cystic fibrosis is an autosomal recessive disorder in which both gene alleles must be mutated for the disorder to be expressed. The nurse should encourage both the client and partner to be tested for the abnormal gene. The other statements are not true.

Answer to Question 2

ANS: B
Cholinergic antagonist drugs cause bronchodilation by inhibiting the parasympathetic nervous system. This allows the sympathetic nervous system to dominate and release norepinephrine that actives beta2 receptors. Bronchodilators relax bronchiolar smooth muscles by binding to and activating pulmonary beta2 receptors. Corticosteroids disrupt the production of pathways of inflammatory mediators. Cromones stabilize the membranes of mast cells and prevent the release of inflammatory mediators.
