LVN Patient Care & Clinical Procedures 5

Question 1

The nurse is preparing a patient for a colonoscopy. Which patient statement indicates a need for further teaching?

Accepted Answer

I can eat a light breakfast the morning of the procedure

Answer

Patients undergoing colonoscopy must have nothing by mouth (NPO) after midnight or per facility policy; eating breakfast would contraindicate the procedure.

Question 2

A nurse notes that a patient's indwelling urinary catheter drainage bag contains 30 mL of urine over 2 hours. What is the priority action?

Accepted Answer

Check for catheter kinks or obstruction, then notify the provider

Answer

Output less than 30 mL/hr suggests oliguria; the nurse should first check for mechanical obstruction, then report to the provider.

Question 3

Which technique should the nurse use to confirm correct nasogastric tube placement before initiating a feeding?

Accepted Answer

Test the pH of aspirated contents — a pH of 0–4 indicates gastric placement

Answer

Aspirate pH of 0–4 is the most reliable bedside method to confirm gastric placement; radiographic confirmation is the gold standard initially.

Question 4

A patient receiving a blood transfusion develops chills, fever, and back pain 15 minutes into the infusion. What is the nurse's first action?

Accepted Answer

Stop the transfusion and keep the IV line open with normal saline

Answer

These are signs of a hemolytic transfusion reaction; the transfusion must be stopped immediately and the IV kept open with NS for possible medications.

Question 5

When performing range-of-motion exercises on a patient's shoulder, the nurse moves the arm in a large circle. This motion is called:

Accepted Answer

Circumduction

Answer

Circumduction is the movement of a limb in a circular pattern, combining flexion, extension, abduction, and adduction.
