NCAS Fundamentals 5

Question 1

A nurse is caring for a patient receiving total parenteral nutrition (TPN). Which complication should the nurse monitor for most closely?

Accepted Answer

Hyperglycemia due to high dextrose concentration

Answer

TPN solutions contain high concentrations of dextrose, placing patients at significant risk for hyperglycemia requiring close blood glucose monitoring.

Question 2

A patient is prescribed potassium chloride 40 mEq IV. The nurse knows that the safe infusion rate for IV potassium should not exceed:

Accepted Answer

10 mEq/hour

Answer

IV potassium should not exceed 10 mEq/hour peripherally to prevent cardiac arrhythmias and vein irritation.

Question 3

When performing tracheal suctioning, which action reduces the risk of hypoxemia?

Accepted Answer

Pre-oxygenate with 100% oxygen before suctioning

Answer

Pre-oxygenating with 100% oxygen before suctioning compensates for the oxygen removed during the suctioning procedure.

Question 4

A patient with a urinary catheter complains of bladder spasms and the urge to void despite the catheter being in place. What should the nurse do first?

Accepted Answer

Assess catheter patency and check for kinks or obstruction

Answer

Catheter-related bladder spasms are often caused by obstruction or kinking of the catheter, so checking patency is the first assessment step.

Question 5

A nurse is preparing to apply antiembolism stockings (TEDs). Which assessment finding is a contraindication to their use?

Accepted Answer

Peripheral arterial disease with absent pedal pulses

Answer

Peripheral arterial disease with absent pulses is a contraindication because compression stockings further reduce already compromised arterial blood flow.
