Answer to Question 1
1. Complete blood count (CBC)
2. Blood type and crossmatch
3. Urine drug screen
Rationale:
The diagnostic tests ordered once the client reaches the hospital depend on the type of injury the client has sustained. Tests that might be ordered include CBC and blood type and crossmatching for the client's serum and donor red blood cells. Blood alcohol level and urine drug screen might be ordered to assess alcohol or drugs. Serum sodium level is important, but not as important as the blood count, crossmatch, and urine drug screen.
Answer to Question 2
B
The rectal route is contraindicated in patients with diarrhea, lesions of the rectum or anus, or for immunosuppressed patients. The rectal route is effective when patients are nauseated and vomiting or when they are unable to eat normally.
