Answer to Question 1

C
Feedback:
CF is a hereditary disease involving the exocrine glands of the respiratory, gastrointestinal, and reproductive tracts. CF results in the accumulation of copious amounts of very thick secretions in the lungs. CF is not caused by bronchospasm or chemical irritation. Patients with cystic fibrosis develop many lung infections but that is secondary to the disease, not the underlying disease process itself.

Answer to Question 2

C
Feedback:
The usual dosage for atropine is 0.4 to 0.6 mg intramuscularly, subcutaneously, or IV; use caution with older patients. The other options are incorrect dosages and therefore wrong.
