1. A nurse is caring for a patient who has undergone a total hip

replacement. The nurse knows that the most common complication of this

surgery is:

a) Infection

b) Hemorrhage

c) Dislocation

d) Thromboembolism

Answer: c) Dislocation

Rationale: Dislocation of the prosthesis can occur if the hip is flexed more

than 90 degrees or if the leg is adducted or internally rotated. The nurse

should instruct the patient to avoid these movements and use an abduction

pillow or wedge to keep the legs apart.

2. A nurse is preparing to administer a blood transfusion to a patient who

has severe anemia. The nurse should perform which of the following

actions before starting the transfusion?

a) Check the patient's vital signs and compare them with the baseline

values

b) Obtain a written consent from the patient or a family member

c) Verify the blood type and Rh factor of the donor and the recipient

d) All of the above

Answer: d) All of the above

Rationale: The nurse should check the patient's vital signs and compare

them with the baseline values to detect any signs of transfusion reaction.

The nurse should also obtain a written consent from the patient or a family

member, as blood transfusion is an invasive procedure that carries some

risks. The nurse should also verify the blood type and Rh factor of the

donor and the recipient, as mismatched blood can cause hemolytic

reaction.

3. A nurse is assessing a patient who has a chest tube connected to a

water-seal drainage system. The nurse observes continuous bubbling in

the water-seal chamber. The nurse should interpret this finding as:

a) Normal

b) Indicating an air leak

c) Indicating fluid overload

d) Indicating infection

Answer: b) Indicating an air leak
