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 C
Explanation
Choice A rationale
Reporting the APs to the charge nurse may seem like an appropriate action, but it does not directly address the conflict. It’s important for the nurse to take an active role in conflict resolution, rather than passing the responsibility to someone else.
Choice B rationale
Allowing the APs to resolve their issues might be a good idea in some situations, but it’s not the best choice here. As a nurse, it’s part of your role to ensure that conflicts are resolved in a way that promotes a positive and productive work environment. By simply allowing the APs to resolve their issues, you’re not taking an active role in conflict resolution.
Choice C rationale
Confronting the APs to discuss their argument is the best choice. This action demonstrates conflict resolution because the nurse is taking an active role in addressing the issue. By discussing the argument with the APs, the nurse can help them understand each other’s perspectives and find a solution that works for everyone.
Choice D rationale
Telling the APs they are acting immaturely is not an effective way to resolve conflict. This approach is likely to escalate the conflict rather than resolve it. It’s important to approach conflicts with a goal of understanding and resolution, rather than placing blame or making judgments.
Correct Answer is B
Explanation
Choice A rationale
While prothrombin level is an important test in evaluating blood clotting disorders, it is not typically used in the initial diagnostic evaluations for a cerebrovascular accident (CVA) or stroke.
Choice B rationale
Brain CT or MRI scans are commonly used in the initial diagnostic evaluations for a CVA. These imaging tests can show bleeding in the brain, an ischemic stroke, a tumor, or other conditions.
Choice C rationale
A chest x-ray is not typically used in the initial diagnostic evaluations for a CVA. It is more commonly used to diagnose conditions affecting the lungs and heart.
Choice D rationale
A lumbar puncture, or spinal tap, may be used in some cases to help diagnose a CVA, but it is not typically part of the initial diagnostic evaluations.
