A nurse is caring for a client who has a prescription for parenteral therapy. Which of the following actions should the nurse take when initiating IV therapy?

Insert the IV catheter using the Z-track technique.

Insert the IV catheter with the bevel down.

Remove the roller clamp from the tubing prior to IV insertion.

Apply the tourniquet 5 to 10 cm (about 2 to 4 in) above the IV insertion site.

Answer and Explanation

The Correct Answer is D

A. "Insert the IV catheter using the Z-track technique." The Z-track technique is used for intramuscular (IM) injections, not IV therapy.
B. "Insert the IV catheter with the bevel down." The bevel should be up to facilitate smooth vein entry.
C. "Remove the roller clamp from the tubing prior to IV insertion." The roller clamp should remain in place to control fluid flow and prevent air from entering the tubing.
D. "Apply the tourniquet 5 to 10 cm (about 2 to 4 in) above the IV insertion site." This placement helps distend the vein for easier cannulation without restricting arterial blood flow.

Correct Answer is C

Explanation

A. Flush the client's tube with 5 mL of water. – This is incorrect because the standard amount of water used to flush a feeding tube is typically 30–50 mL to maintain patency and prevent clogging.
B. Place the client in a supine position. – This is incorrect because the client should be placed in a semi-Fowler’s or Fowler’s position (at least 30–45 degrees) to reduce the risk of aspiration.
C. Check the pH level of the client's gastric contents. – This is the correct answer. Checking the pH of gastric contents (typically ≤5.5) helps confirm proper tube placement before administering feedings, reducing the risk of aspiration.
D. Check the patency of the client's tube every 8 hr. – This is incorrect because tube patency should be checked before each feeding or medication administration, not just every 8 hours.

A. Temperature of 38° C (100.4° F) B. Respiratory rate of 10/min C. Heart rate of 112/min D. Blood pressure of 136/88 mm Hg

Correct Answer is C

Explanation

A. Temperature of 38° C (100.4° F) A slight fever is not a primary sign of internal bleeding. It could be related to infection or another inflammatory response.
B. Respiratory rate of 10/min Internal bleeding is more likely to cause an increased respiratory rate (tachypnea) due to hypoxia rather than a decreased rate.
C. Heart rate of 112/min Tachycardia (HR >100 bpm) is an early sign of internal bleeding. The body increases the heart rate to compensate for blood loss and maintain perfusion.
D. Blood pressure of 136/88 mm Hg While low blood pressure (hypotension) can indicate severe internal bleeding, this BP is within normal range. However, a sudden drop in BP later would be a concerning sign.
