CPNRE Nursing Care and Interventions 2

Question 1

A client has an NGT and is ordered tube feeding. Before starting, which action confirms correct tube placement?

Accepted Answer

Check pH of aspirate and verify tube length marking at the nose

Answer

Checking aspirate pH (gastric pH <5.5) and verifying tube length marking are evidence-based methods to confirm NGT placement.

Question 2

A client has been ordered a glycerin suppository. Which action should be taken before insertion?

Accepted Answer

Warm to body temperature and lubricate with water-soluble lubricant

Answer

Warming a suppository prevents cold-induced anal sphincter spasm, and water-soluble lubricant facilitates smooth insertion.

Question 3

When inserting a urinary catheter for a male client, the catheter meets resistance at the external urethral sphincter. What is the most appropriate action?

Accepted Answer

Ask the client to take a deep breath and relax, then gently advance

Answer

Deep breathing relaxes the external sphincter voluntarily, allowing gentle advancement without causing injury.

Question 4

A client is prescribed subcutaneous heparin 5000 units. Which administration technique is most appropriate?

Accepted Answer

Inject into the abdomen 5 cm from the umbilicus, do not aspirate, do not massage

Answer

Subcutaneous heparin: inject into the abdomen (5 cm from navel), do not aspirate (increases bleeding risk), do not massage (causes bruising and alters absorption).

Question 5

When changing a wound dressing, which finding requires immediate reporting?

Accepted Answer

A wound base that becomes deep red, firm, with surrounding pale indented tissue and foul odor

Answer

A deep red firm wound base with surrounding pale indentation and foul odor suggests wound infection, possible deep tissue injury, or necrotizing process.
