LPN Standard Precautions and Transmission-Based Precautions 2

Question 1

A patient is diagnosed with pulmonary tuberculosis. Which type of transmission-based precaution should be implemented?

Accepted Answer

Airborne precautions

Answer

Pulmonary TB is transmitted via small airborne particles (droplet nuclei) that remain suspended in air, requiring airborne precautions including a negative-pressure room and N95 respirator.

Question 2

Which action is correct when removing contaminated gloves?

Accepted Answer

Grasp the outside of one glove at the wrist and peel it off, then slide fingers under the remaining glove's cuff

Answer

The correct technique avoids touching the contaminated outer surface by peeling the first glove off from the wrist and using the clean inner surface of the second glove to remove it.

Question 3

A nurse is caring for a patient on droplet precautions. What is the minimum distance at which a surgical mask must be worn?

Accepted Answer

6 feet

Answer

Droplet precautions require wearing a surgical mask when within 6 feet (about 2 meters) of the patient, as large respiratory droplets typically travel this distance.

Question 4

Which infection requires both airborne AND contact precautions?

Accepted Answer

Varicella (chickenpox)

Answer

Varicella (chickenpox) spreads via both airborne droplet nuclei and direct contact with vesicle fluid, requiring a combination of airborne and contact precautions.

Question 5

Standard precautions apply to which body fluids?

Accepted Answer

Blood, body fluids, secretions, and excretions (except sweat)

Answer

Standard precautions apply to blood, all body fluids, secretions, and excretions (except sweat), regardless of whether they contain visible blood.
