A nurse is caring for a client who is receiving oxygen therapy via a nasal cannula. The nurse explains to the client that this method of oxygen delivery does which of the following?

Restricts the client's ability to eat, speak, or drink

Delivers a constant rate of a specific concentration of oxygen

Delivers a high concentration of oxygen

Delivers a low concentration of oxygen

Answer and Explanation

The Correct Answer is D

A reason:

Restricting the client's ability to eat, speak, or drink is incorrect. A nasal cannula is designed to allow clients to eat, speak, and drink comfortably while receiving oxygen therapy.

B reason:

Delivering a constant rate of a specific concentration of oxygen is somewhat accurate but incomplete. The concentration can vary based on the flow rate set by the healthcare provider.

C reason:

Delivering a high concentration of oxygen is incorrect. Nasal cannulas typically provide low to moderate concentrations of oxygen, depending on the flow rate (usually 1-6 liters per minute).

D reason:

Delivering a low concentration of oxygen is correct. Nasal cannulas are used to provide supplemental oxygen at low flow rates, suitable for clients who require minimal assistance with their oxygen levels.

Correct Answer is C

Explanation

A reason: Pallor. Pallor refers to an abnormal paleness of the skin, which can be caused by various conditions such as anemia or shock. It is not related to heart rate.

B reason: Bradypnea. Bradypnea refers to an abnormally slow breathing rate. It is unrelated to heart rate and is not the correct term for describing an elevated heart rate.

C reason: Tachycardia. Tachycardia is the medical term for an abnormally fast heart rate, typically defined as a heart rate over 100 beats per minute. A heart rate of 115 falls into this category, making tachycardia the correct term.

D reason: Somnolence. Somnolence refers to a state of drowsiness or sleepiness. It is not related to heart rate and is not the appropriate term for describing an elevated heart rate.

A. It is acceptable to use alcohol-based hand products after most client contact. B. I should wash my hands before I provide client care. C. I will not wear artificial nails when providing client care. D. As long as I change gloves between clients, it is not necessary to wash my hands.

Correct Answer is D

Explanation

A reason:

Using alcohol-based hand products after most client contact is acceptable and effective in maintaining hand hygiene, particularly when soap and water are not readily available.

B reason:

Washing hands before providing client care is a fundamental practice in infection control and is essential to prevent the spread of pathogens.

C reason:

Not wearing artificial nails when providing client care is important for infection control. Artificial nails can harbor bacteria and other pathogens, increasing the risk of transmitting infections.

D reason:

Changing gloves between clients without washing hands is incorrect and indicates a need for further teaching. Hand hygiene is necessary even when gloves are used to prevent cross-contamination. Gloves are not a substitute for proper hand washing.
