IV Patient Assessment & Monitoring 3

Question 1

Which parameter is MOST important to monitor in a patient receiving hypertonic saline (3% NaCl)?

Accepted Answer

Serum sodium levels and neurological status

Answer

Hypertonic saline corrects severe hyponatremia; monitoring serum sodium and neuro status prevents osmotic demyelination syndrome from overcorrection.

Question 2

When performing a pre-infusion assessment, the nurse notes the patient has a documented penicillin allergy. The ordered IV antibiotic is cephalexin. The nurse should:

Accepted Answer

Withhold the drug and clarify with the prescriber

Answer

Cross-reactivity between penicillins and cephalosporins exists; the nurse must clarify with the prescriber before administering due to potential allergic reaction.

Question 3

A patient's IV site shows a Phlebitis Scale score of 3 (erythema, streak formation, and palpable cord). The correct action is:

Accepted Answer

Discontinue the IV and restart at a new site

Answer

A phlebitis score of 3 or above requires discontinuation of the IV catheter and insertion at a new site to prevent further vascular damage.

Question 4

During a peripheral IV assessment, the nurse notices blood backing up into the tubing when the bag is lowered below the insertion site. This indicates:

Accepted Answer

Patent IV with adequate venous pressure

Answer

Blood return when the IV bag is lowered below the site confirms catheter patency and proper venous placement.

Question 5

A patient receiving potassium chloride IV develops peaked T waves on telemetry. This finding indicates:
