A nurse is teaching a class about skeletal muscles.
Which of the following should the nurse identify as a function of skeletal muscles?

Skeletal muscles enable the heart to contract with each heartbeat

Skeletal muscles enable the bladder to contract during voiding

Skeletal muscles enable the bronchioles to dilate in the lungs

Skeletal muscles enable a hand to contract and form a fist

Answer and Explanation

The Correct Answer is D

Choice A rationale
Skeletal muscles do not enable the heart to contract with each heartbeat. The heart has its own specialized muscle tissue known as cardiac muscle, which allows it to contract and pump blood throughout the body.
Choice B rationale
Skeletal muscles do not enable the bladder to contract during voiding. The detrusor muscle, a smooth muscle found in the wall of the bladder, contracts during urination to expel urine from the body.
Choice C rationale
Skeletal muscles do not enable the bronchioles to dilate in the lungs. The dilation and constriction of the bronchioles are controlled by the autonomic nervous system and the smooth muscles in the walls of the bronchioles.
Choice D rationale
Skeletal muscles do enable a hand to contract and form a fist. Skeletal muscles are responsible for all voluntary movements, including making a fist. When you want to make a fist, your brain sends a signal to the skeletal muscles in your hand and forearm, telling them to contract. This pulls on the tendons connected to your fingers, causing them to move and form a fist.

Repentance is not typically included in the five stages of grief as outlined by psychiatrist Elisabeth Kübler-Ross.
Choice B rationale
Bargaining is one of the five stages of grief. It often involves the individual making deals or promises to a higher power in an attempt to reverse or lessen the loss.
Choice C rationale
Depression is a stage of grief where the individual may experience intense feelings of sadness, hopelessness, and despair.
Choice D rationale
Acceptance is the final stage of grief, where the individual begins to accept the reality of their loss.

A. Check the patient’s visual acuity using a Snellen chart. B. Whisper in one of the patient’s ears while blocking the other. C. Observe the patient’s ability to turn their head from side to side. D. Ask the patient to identify specific smells. E. Ask the patient to identify specific smells.

Correct Answer is C

Explanation

Choice A rationale
Checking the patient’s visual acuity using a Snellen chart is used to assess cranial nerve II (Optic), not cranial nerve XI (Spinal Accessory)3.
Choice B rationale
Whispering in one of the patient’s ears while blocking the other is a method used to assess cranial nerve VIII (Vestibulocochlear), not cranial nerve XI4.
Choice C rationale
Observing the patient’s ability to turn their head from side to side is a correct method to assess cranial nerve XI. This nerve innervates the sternocleidomastoid and trapezius muscles, which are responsible for turning the head and shrugging the shoulders respectively.
Choice D rationale
Asking the patient to identify specific smells is used to assess cranial nerve I (Olfactory), not cranial nerve XI3.
