Question 1 of 5
A client with a head injury asks why he cannot have something for his headache. The nurse's response is based on the understanding that analgesics could:
Correct Answer: C
Rationale: Analgesic medication does not counteract the effects of antibiotics. Analgesic medication may lower blood pressure elevated due to anxiety. Analgesic medication, especially CNS depressants, is not given if there is danger of increasing ICP, because neurological changes may not be apparent. Also, further depression of the CNS is contraindicated. Analgesics do not stimulate the CNS.
Question 2 of 5
A female client is started on warfarin (Coumadin) 5 mg po bid. To adequately evaluate the effectiveness of the warfarin therapy, the nurse must know that this medication:
Correct Answer: C
Rationale: Thrombolytic agents (e.g., streptokinase) directly activate plasminogen, dissolving fibrin deposits, which in turn dissolves clots that have already formed. Heparin prevents the formation of clots by potentiating the effects of antithrombin III and the conversion of prothrombin to thrombin. Warfarin prevents the formation of clots by interfering with the hepatic synthesis of the vitamin K-dependent clotting factors. Platelets initiate the coagulation of blood by adhering to each other and the site of injury to form platelet plugs.
