Answer to Question 1
D
Feedback:
Unlike active immunity, passive immunity is limited. It lasts only as long as the circulating antibodies last because the body does not produce its own antibodies as found in active immunity. People are born with active immunity in which the body recognizes a foreign protein and begins producing antibodies to react with specific proteins or antigens. Serum sickness is a massive immune reaction against the injected antibodies that occur with passive immunity.
Answer to Question 2
A
Feedback:
If halothane and ketamine are used in combination, severe cardiac depression with hypotension and bradycardia may occur. If these agents must be used together, the patient should be monitored closely. Pain, respirations, airway, and temperature are all assessments the nurse will collect on any patient in the PACU, but they are not priority assessments associated with combining ketamine and halothane.
