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
Skeletal muscles enable a hand to contract and form a fist
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.

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Slow capillary refill is a sign that the body is not circulating blood as effectively as it should be. This can be a sign that a person is actively dying.
Choice B rationale
Ringing in the ears, also known as tinnitus, is not typically a sign that a person is actively dying. It can be caused by a variety of factors, including exposure to loud noise, certain medications, and some health conditions.
Choice C rationale
Cold hands and feet can be a sign that a person is actively dying. As the body’s systems start to shut down, blood flow to the extremities can decrease, causing them to feel cold.
Choice D rationale
Mottled and blotchy skin, especially on the hands, feet, and knees, can be a sign that a person is actively dying. This is caused by reduced blood flow to the skin.
Correct Answer is A
Explanation
Choice A rationale
Herpes simplex virus encephalitis is a severe condition that requires immediate treatment. The most common medication used for this condition is acyclovir, which is administered intravenously. Acyclovir works by inhibiting the replication of the virus, thereby reducing the severity and duration of the infection.
Choice B rationale
Cyclosporine is an immunosuppressive medication that is often used to prevent organ rejection after transplantation. It is not typically used in the treatment of viral infections such as herpes simplex virus encephalitis.
Choice C rationale
Without specific information about “Medication C”, it’s difficult to provide a rationale.
However, it’s important to note that the treatment of herpes simplex virus encephalitis typically involves antiviral medications, with acyclovir being the most commonly used.
Choice D rationale
Similar to Choice C, without specific information about “Medication D”, providing a rationale is challenging. As mentioned, the standard treatment for herpes simplex virus encephalitis is acyclovir.
