Question 1 of 5
Which one of the following lab tests should be done periodically if the client is being maintained on warfarin sodium (Coumadin)?
Correct Answer: A
Rationale: Warfarin’s anticoagulant effect is monitored by INR (derived from prothrombin time), but periodic platelet counts are also checked to assess for thrombocytopenia, a potential side effect. White cell, neutrophil, and basophil counts are less relevant.
Question 2 of 5
A client with a head injury has an intracranial pressure (ICP) monitor in place. Cerebral perfusion pressure calculations are ordered. If the client's ICP is 22 and the mean pressure reading is 70, what is the client's cerebral perfusion pressure?
Correct Answer: 58
Rationale: Cerebral perfusion pressure (CPP) is calculated as CPP = MAP - ICP. Given MAP = 70 mmHg and ICP = 22 mmHg, CPP = 70 - 22 = 48 mmHg. Thus, the correct answer is 48.
