The Correct Answer is A
A. Chvostek's sign is a clinical sign observed during physical examination that may indicate hypocalcemia. It is elicited by tapping or lightly striking the facial nerve just anterior to
the earlobe, which can cause twitching of the facial muscles, particularly the muscles around the mouth and nose.
B. This image shows winging of the scapula. Winging of the scapula, also known as
scapular winging, is a condition characterized by the abnormal protrusion or prominence of the scapula away from the back wall of the thorax. Normally, the scapula lies flat
against the rib cage, providing stability and support for arm movements.

Correct Answer is C
Explanation
A. Wearing shoes with smooth soles may increase the risk of slipping and falling, especially for a client with mobility issues. It is not a safe recommendation.
B. Moving the cane forward 18 inches is too far and may lead to instability during ambulation.
Typically, the cane should be moved forward only about 6 to 12 inches.
C. Holding the cane on the stronger side provides better support and stability, as it allows the client to bear weight on the stronger side while using the cane for balance and support on the weaker side.
D. Moving the stronger leg forward before the weaker leg is a correct step in the gait pattern when using a cane or other assistive device for walking. However, the statement does not
specifically address the use of the quad cane.
Correct Answer is C
Explanation
A. Simple face mask: This can deliver oxygen at flow rates of 5-10 liters per minute and typically provides an oxygen concentration of about 35-50%.
B. Nasal prongs: Nasal prongs deliver oxygen at lower flow rates and may not be sufficient to raise the client's oxygen saturation to 90%.
C. Non-rebreather mask: This mask can deliver high concentrations of oxygen (up to 90-100%) at flow rates of 10-15 liters per minute. It has one-way valves to prevent the patient from rebreathing exhaled air, thus maximizing the delivery of oxygen.
D. Nasal cannula: Nasal cannulas deliver oxygen at lower flow rates (typically up to 6 liters per minute) and may not provide the necessary concentration to achieve an oxygen saturation of 90%.
