The nurse is teaching a client how to do active range of motion (ROM) exercises.
To exercise the hinge joints, which action should the nurse instruct the client to perform?

Tap the feet forwards and backwards.

Bend the arm by flexing the ulna to the humerus.

Turn the head to the right and left.

Extend the arm at the side and rotate in circles.

Answer and Explanation

The Correct Answer is B

To exercise the hinge joints, the nurse should instruct the client to bend the arm by flexing the ulna to the humerus.

Hinge joints allow for movement in one direction, like a door hinge. The elbow joint is an example of a hinge joint.

Choice A is not the answer because tapping the feet forwards and backwards exercises the ankle joint, which is not a hinge joint.

Choice C is not the answer because turning the head to the right and left exercises the pivot joint in the neck, which is not a hinge joint.

Choice D is not the answer because extending the arm at the side and rotating in circles exercises the ball-and-socket joint in the shoulder, which is not a hinge joint.

Correct Answer is C

Explanation

A. 3 mL syringe and a sterile needle.
This is incorrect. A sterile needle is unnecessary for administering an oral medication. Syringes with needles are used for injections, not for measuring or delivering oral medications.

B. One ounce medicine cup.
This is incorrect. While a medicine cup can be used for liquid medications, it is not precise for small volumes such as 2 mL. The graduations on a medicine cup are typically in larger increments, making it difficult to measure accurately.

C. 3 mL syringe.
This is correct. A 3 mL syringe is precise and suitable for measuring a 2 mL dose of a viscous liquid. Syringes provide clear markings, ensuring accurate measurement of small volumes. Additionally, the absence of a needle makes it appropriate for oral administration.

D. Tuberculin syringe.
This is incorrect. Although a tuberculin syringe can accurately measure small doses, it is designed for very small volumes, such as 1 mL or less. A 3 mL syringe is more appropriate for a 2 mL dose.

Correct Answer is ["16"]

Explanation

The healthcare provider prescribed 800,000 units of penicillin and the vial available is labeled 50,000 units/mL.

To calculate the number of mL to administer, you need to divide the total number of units prescribed (800,000) by the number of units per mL (50,000).

This gives you a result of 16 mL.

Therefore, the nurse should administer 16 mL of penicillin to the patient.
