A nurse is preparing to administer methylphenidate 7.5 mg PO to a school-age child who has ADHD. The amount available is methylphenidate oral solution 5 mg/5 mL. How many mL of the medication should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["7.5"]
Calculation:
Desired dose = 7.5 mg
Available concentration = 5 mg / 5 mL
= 1 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 7.5 mg / 1 mg/mL
= 7.5 mL

Correct Answer is B
Explanation
A: Image A shows the ankle area, which is an example of a hinge joint, not a ball and socket joint. Hinge joints allow movement in one plane, such as flexion and extension, similar to the motion of a door hinge. The ankle allows primarily up-and-down movement but does not rotate in multiple directions like a ball and socket joint would.
B: Image B shows the hip area, which represents a ball and socket joint. In a ball and socket joint, the round head of one bone fits into the cup-like socket of another bone, allowing movement in multiple directions. The hip and the shoulder are classic examples of ball and socket joints, permitting rotation, flexion, extension, abduction, and adduction.
Correct Answer is A
Explanation
A. Powered-standing assist lift: A powered-standing assist lift is appropriate for a cooperative client with upper body strength who is non-weight bearing. It allows the client to participate by supporting themselves with their arms while the device safely moves them from the bed to a chair without bearing weight on their lower extremities.
B. Draw sheet: A draw sheet is typically used for repositioning a client in bed, not for transferring them from bed to chair. It does not provide the mechanical support needed to lift and transfer a non-weight-bearing client safely.
C. Gait belt: A gait belt is useful for clients who can bear weight to some degree and require minimal assistance during transfers. Since this client is non-weight-bearing, a gait belt alone would not provide adequate support and could lead to injury.
D. Full body sling lift: A full body sling lift is used for clients who are non-weight bearing and lack the ability to assist in transfers. Since the client described here is cooperative and has upper body strength, a full sling would not be necessary and may restrict their participation.
