LVN IV Therapy & Fluid Management 4

Question 1

According to INS guidelines, peripheral IV catheters in adults should be routinely assessed for site rotation every how many hours?

Accepted Answer

72–96 hours

Answer

INS guidelines recommend assessing peripheral IV sites every 72–96 hours and rotating as needed to prevent phlebitis and infection.

Question 2

A patient receiving IV fluids develops sudden onset dyspnea, crackles, and an S3 heart sound. Which fluid-related complication is most likely?

Accepted Answer

Circulatory overload (TACO)

Answer

Transfusion-Associated Circulatory Overload (TACO) or fluid volume excess presents with dyspnea, crackles, and S3 gallop due to too-rapid IV fluid administration.

Question 3

Which action is essential before initiating any blood product transfusion to ensure patient safety?

Accepted Answer

Have two nurses verify the patient's name and blood type against the unit label

Answer

Two-nurse verification of patient identity and blood product compatibility is the critical safety step to prevent potentially fatal transfusion errors.

Question 4

A patient's serum sodium is 128 mEq/L. Which clinical manifestations would the LVN expect?

Accepted Answer

Nausea, headache, lethargy, and muscle cramps

Answer

Hyponatremia (Na+ < 135 mEq/L) causes nausea, headache, lethargy, muscle cramps, and in severe cases seizures due to cerebral edema.

Question 5

An IV infusion pump alarm sounds indicating 'occlusion.' What should the LVN check first?

Accepted Answer

Check for kinks in the tubing, a closed clamp, or positional obstruction

Answer

Occlusion alarms most commonly result from kinked tubing, a closed roller clamp, or positional obstruction that the nurse should systematically assess.
