Question 1

A 77-year-old patient is being treated for cardiac arrhythmia.The nurse determines that the patient's cardiac output is adequate with which assessments? (Select all that apply. )
A)Urine output of 140 cc over 4 hours
B)Systolic blood pressure that remains within 20 mm of baseline
C)Denial of substernal pain
D)Recollection of the birthdays of all of her grandchildren
E)Absence of rales and crackles

Accepted Answer

The patient will maintain an adequate cardiac output,as evidenced by heart rate and rhythm within normal range,stable blood pressure,adequate peripheral pulses,mental alertness,urine output of 30 mL/hr,and clear breath sounds.Normal mentation also denotes good cardiac output,but the patient may have too many birthdays to remember,so this is not the best indicator of cognitive status.

Question 2

An older adult recovering from a myorcardial infarction (MI)has been taking subcutaneous heparin but is now to receive oral warfarin (Coumadin).The nurse prepares to teach the patient which topics? (Select all that apply. )
A)Administration of both medications for up to 5 days
B)Need to use a soft bristle toothbrush
C)Use of atropine as an antidote for excessive bleeding
D)Need to continue drawing partial thromboplastin times
E)Need to drink at least eight cups of fluids daily

Accepted Answer

Heparin and warfarin (Coumadin)are anticoagulants used to prevent the enlargement of existing thrombi and new clot formation after an MI.Therapeutic effects of heparin are monitored by partial thromboplastin times;the antidote is protamine sulfate.Warfarin is monitored by the international normalized ratio (INR);the antidote is vitamin K.Patients who initially receive heparin for anticoagulation and who need oral anticoagulation for maintenance usually take both forms of medication for 3 to 5 days to develop therapeutic blood levels.Bleeding is a complication.Patients need to be taught bleeding precautions.

E)Strategies to include exercise into daily routine
