CNA Basic Nursing Skills 7 2

Question 1

A resident on oxygen therapy has nasal cannula prongs that have become displaced. What should the CNA do?

Accepted Answer

Reposition the cannula prongs in the nostrils and adjust the tubing for comfort

Answer

The CNA should reposition the nasal cannula to ensure the resident continues to receive prescribed oxygen, then assess for comfort and check that the flow rate is unchanged.

Question 2

What is the CNA's primary responsibility regarding oxygen therapy?

Accepted Answer

Observing the resident for respiratory distress and reporting abnormalities to the nurse

Answer

CNAs observe residents on oxygen therapy for signs of respiratory distress and report changes, but do NOT adjust flow rates or discontinue therapy.

Question 3

What should the CNA do if a resident on oxygen becomes severely short of breath and cyanotic (blue lips)?

Accepted Answer

Elevate the head of the bed and call for the nurse immediately

Answer

Elevating the head of the bed facilitates breathing and calling the nurse immediately is the correct emergency response to acute respiratory distress.

Question 4

Why is smoking prohibited in areas where oxygen is in use?

Accepted Answer

Oxygen is highly flammable and smoking creates a serious fire and explosion hazard

Answer

Oxygen supports combustion; a spark or flame near an oxygen source can cause rapid ignition and explosion, creating a life-threatening fire hazard.

Question 5

When observing a resident's respirations, which finding should be reported immediately?

Accepted Answer

Respiratory rate of 8 breaths per minute with shallow depth

Answer

A rate of 8 breaths per minute (bradypnea) with shallow depth indicates inadequate ventilation and requires immediate nursing assessment.
