Question 2

The nurse is caring for a patient who has undergone major abdominal surgery.The nurse notices that the patient's urine output has been less than 20 mL/hour for the past 2 hours.The patient's blood pressure is 100/60 mm Hg,and the pulse is 110 beats/min.Previously,the pulse was 90 beats/min with a blood pressure of 120/80 mm Hg.The nurse should

Accepted Answer

A)  contact the provider and expect a prescription for a normal saline bolus. 
B)  wait until the provider makes rounds to report the assessment findings. 
C)  continue to evaluate urine output for 2 more hours. 
D)  ignore the urine output, as this is most likely postrenal in origin.

B)  diffusion. 
C)  clearance. 
D)  ultrafiltration.

Question 8

The patient is getting hemodialysis for the second time when he complains of a headache and nausea and,a little later,of becoming confused.The nurse realizes these are symptoms of

Accepted Answer

A)  dialyzer membrane incompatibility. 
B)  a shift in potassium levels. 
C)  dialysis disequilibrium syndrome. 
D)  hypothermia.
