Question 2

The LPN is caring for a patient in Buck's traction. Which assessment is most important?

Accepted Answer

Skin integrity under the traction boot

Question 3

A patient taking lithium reports nausea, tremor, and blurred vision. The LPN recognizes these as signs of:

Lithium toxicity

Nausea, tremors, and blurred vision are early signs of lithium toxicity, which has a narrow therapeutic index (0.6–1.2 mEq/L).

Question 4

When teaching a patient about iron supplement administration, the LPN should instruct the patient to take it:

Iron is best absorbed on an empty stomach, and vitamin C (ascorbic acid) enhances iron absorption by keeping it in the ferrous state.

A patient with a history of COPD is admitted with increased dyspnea. Which oxygen delivery method should the LPN anticipate using?

Accepted Answer

Venturi mask at a controlled FiO2

COPD patients require controlled, low-concentration oxygen via a Venturi mask to avoid suppressing their hypoxic respiratory drive.
