LPN Ultimate 2

Question 1

A patient on warfarin reports eating large amounts of leafy green vegetables daily. What is the primary concern?

Accepted Answer

Decreased anticoagulant effect due to high vitamin K intake

Answer

Vitamin K antagonizes warfarin's anticoagulant effect, so high intake of leafy greens can decrease INR and increase clot risk.

Question 2

When performing a sterile dressing change, the LPN accidentally touches the sterile field with an ungloved hand. What is the correct action?

Accepted Answer

Discard the contaminated supplies and obtain a new sterile setup

Answer

Any break in sterile technique requires discarding contaminated materials and starting fresh to prevent infection.

Question 3

A patient's oxygen saturation drops to 88% while sleeping. Which position change should the LPN implement first?

Accepted Answer

High Fowler's position

Answer

High Fowler's position (60–90°) maximizes lung expansion and improves oxygenation by reducing pressure on the diaphragm.

Question 4

A patient with end-stage renal disease is prescribed aluminum hydroxide antacids. What is the therapeutic purpose in this population?

Accepted Answer

Binding dietary phosphate in the GI tract

Answer

In ESRD, aluminum hydroxide binds phosphate in the gut to reduce hyperphosphatemia, a common complication of renal failure.

Question 5

Which assessment finding in a postoperative patient requires immediate reporting to the charge nurse?

Accepted Answer

Blood pressure of 88/52 mmHg

Answer

A blood pressure of 88/52 mmHg indicates hypotension, a sign of possible hemorrhage or shock requiring immediate intervention.
