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
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 A
Explanation
A reason:
A pH reading of 1-4 is expected for gastric contents. This acidic range indicates that the NG tube is correctly placed in the stomach, where gastric secretions have a low pH due to hydrochloric acid.
B reason:
A pH reading of 5-7 is more indicative of respiratory secretions or the contents of the small intestine, not the stomach. This range suggests that the NG tube may be incorrectly placed.
C reason:
A pH reading of 8-10 is too alkaline for gastric contents and indicates incorrect tube placement. This range could suggest the presence of intestinal or respiratory secretions, not gastric.
D reason:
A pH reading of 11-14 is highly alkaline and unlikely to be encountered in clinical practice for this purpose. Such a high pH is not compatible with gastric contents and suggests a significant error or contamination in the test.
Correct Answer is A
Explanation
A reason:
When walking, moving the left foot forward first is correct. For clients with left-sided weakness, the cane should be used to provide support for the weak side. Moving the left foot first while using the cane helps maintain balance and stability.
B reason:
Keeping the elbow straight when holding the cane is incorrect. The elbow should be slightly bent when holding the cane to allow for better control and shock absorption, reducing strain on the arm.
C reason:
Moving the cane forward 18 inches with each step is incorrect. The cane should be moved a comfortable distance forward, typically about 6 to 12 inches, to maintain stability and support without overreaching.
D reason:
Holding the cane with the left hand is incorrect. For left-sided weakness, the cane should be held in the right hand to provide support and balance on the opposite side of the weakness.
