Question 1 of 5
A nurse is teaching a class about skeletal muscles. Which of the following should the nurse identify as a function of skeletal muscles?
Correct Answer: D
Rationale: The correct answer is D: Skeletal muscles enable a hand to contract and form a fist. Skeletal muscles are responsible for voluntary movements, such as forming a fist, walking, and lifting objects. This function aligns with the voluntary control of skeletal muscles over body movements.
Choices A, B, and C are incorrect because the heart muscle (cardiac muscle) contracts involuntarily, the bladder muscle contracts involuntarily, and the bronchioles in the lungs dilate due to smooth muscle contraction, not skeletal muscle. It is essential to differentiate between the involuntary functions of cardiac and smooth muscles and the voluntary functions of skeletal muscles.
