A nurse is teaching a client who has left hemiparesis how to use a cane. Which of the following instructions should the nurse include?
Hold the cane on the right side to provide support for the weaker leg
Remove the rubber tip when using the cane.
Advance the right leg and the cane together to support the weaker leg
Place the cane approximately 61 cm (24 in) in front of her feet before advancing
The Correct Answer is A
A: The correct instruction is to hold the cane on the right side, which is the side opposite the weaker leg. This provides better support and balance for the weaker side.
B: Removing the rubber tip from the cane is not recommended. The rubber tip provides traction and stability, reducing the risk of slipping.
C: Advancing the right leg and the cane together is incorrect. The cane should move with the weaker leg (left leg in this case) to provide support during ambulation.
D: Placing the cane 61 cm (24 in) in front of the feet is too far. The cane should be placed about 15-25 cm (6-10 in) in front of the feet to provide optimal support and balance.

Correct Answer is A
Explanation
A: Posting a “No Smoking” sign in the home is crucial for safety when using home oxygen. Oxygen can accelerate combustion, making even a small spark potentially dangerous. This sign serves as a constant reminder to avoid smoking and open flames near the oxygen source.
B: Attaching oxygen containers to a fixed object is important to prevent them from falling over and potentially causing damage or leaks. However, this is not the most critical instruction compared to ensuring no smoking around oxygen.
C: Storing spare oxygen tanks in a closet is not recommended. Oxygen tanks should be stored in a well-ventilated area to prevent the buildup of oxygen, which could increase the risk of fire.
D: Notifying the fire department that oxygen is used in the home is a good safety measure. It ensures that emergency responders are aware of the presence of oxygen, which can affect their approach in case of a fire. However, it is not as immediate a safety measure as posting a “No Smoking” sign.
E: Ensuring oxygen tubing is no longer than 60 feet in length is important to maintain adequate oxygen flow and prevent tripping hazards. However, this is a secondary safety measure compared to preventing smoking around oxygen.
Correct Answer is B
Explanation
A: A BUN level of 165 mg/dL is extremely high and suggests severe dehydration or possible renal failure. This level is far above the normal range and indicates a critical condition.
B: A BUN level of 35 mg/dL is elevated and consistent with dehydration. Dehydration causes the kidneys to reabsorb more water, leading to higher concentrations of urea in the blood.
C: A BUN level of 10 mg/dL is within the normal range and does not indicate dehydration. This level suggests normal kidney function and hydration status.
D: A BUN level of 31 mg/dL is elevated and suggests dehydration. While not as high as 165 mg/dL, it still indicates that the patient is dehydrated and requires intervention.
