A nurse is caring for a client who is receiving oxygen via nasal cannula at 4 L/min. Which of the following actions should the nurse take?

Avoid the use of humidifiers.

Position the cannula prongs curving upward in the nose.

Clean the cannula prongs daily.

Keep the oxygen tubing off the floor.

Answer and Explanation

The Correct Answer is C

Clean the cannula prongs daily.

This is because the nasal cannula can become contaminated with bacteria and mucus, which can cause infection and irritation of the nasal mucosa. Cleaning the cannula prongs daily with soap and water can prevent these complications.

Choice A is wrong because humidifiers can help moisten the dry oxygen and prevent nasal dryness and bleeding. Humidifiers should be used for oxygen flow rates higher than 4 L/min.

Choice B is wrong because the cannula prongs should be positioned curving downward in the nose, not upward. This allows for better alignment with the natural direction of airflow and reduces the risk of dislodgement.

Choice D is wrong because keeping the oxygen tubing off the floor is not a specific action for nasal cannula use. It is a general safety measure to prevent tripping and contamination of the tubing.

Correct Answer is B

Explanation

Obturator.

An obturator is a device that is inserted into the tracheostomy tube to guide it through the stoma and prevent tissue damage. It should be removed after the tube is inserted and kept near the bedside in case of accidental decannulation.

Choice A is wrong because povidone-iodine is an antiseptic solution that is not routinely used for tracheostomy care. It can cause skin irritation and damage to the mucous membranes.

Choice C is wrong because an irrigation set is not needed for a tracheostomy tube.

Irrigation can introduce bacteria and increase the risk of infection. It can also cause coughing and bleeding.

Choice D is wrong because hemostats are not used for a tracheostomy tube.

Hemostats are surgical instruments that are used to clamp blood vessels or tissues. They have no role in tracheostomy care.

Some other supplies that the nurse should place in the room are a trach tube the same size as the current tube and one size smaller, a portable suction machine with battery backup, and tubing that connects to the suction machine. Other supplies may include saline solution, syringes, gauze squares, gloves, a trachea tube brush, a waterproof drape, non-woven sponges, pipe cleaners, cotton tipped applicators, a T-drain sponge, twill tape, a trach holder, a speaking valve, a stoma cover, and a nebulizer.

A. Use a recliner when sitting for long periods. B. Apply moist heat to the knees. C. Sleep on a soft mattress. D. Place large pillows under the knees when lying in bed. E. Place large pillows under the knees when lying in bed.

Correct Answer is B

Explanation

Moist heat can help reduce pain and stiffness in the joints by increasing blood flow and relaxing the muscles. Moist heat can be applied using warm compresses, heating pads, or warm baths.

Choice A is wrong because using a recliner when sitting for long periods can increase pressure on the knees and decrease circulation. A better option is to use a straight-backed chair with a footstool.

Choice C is wrong because sleeping on a soft mattress can cause poor alignment of the spine and joints, which can worsen pain and mobility. A firm mattress is recommended for clients with osteoarthritis.

Choice D is wrong because placing large pillows under the knees when lying in bed can limit the range of motion of the knees and cause contractures. A small pillow under the knees can provide some support and comfort, but it should not be too large or too high.
