A nurse is working with a nursing student to care for several clients who have musculoskeletal injuries. The nurse should identify which of the following functions of the musculoskeletal system? (Select All that Apply)
Production of potassium
Maintains the body’s form and shape
Provides reflexive responses to injuries
Formation of blood cells through red or yellow marrow
Protection of soft organs
Correct Answer : B,D,E
Choice A Reason: Production of potassium
The musculoskeletal system does not produce potassium. Potassium is an essential mineral that is obtained through the diet and is crucial for various bodily functions, including muscle contraction and nerve function. The musculoskeletal system, however, is not involved in its production.
Choice B Reason: Maintains the body’s form and shape
One of the primary functions of the musculoskeletal system is to maintain the body’s form and shape. The skeletal system provides the framework that supports the body and gives it structure. Muscles attached to the bones help maintain posture and allow for movement, contributing to the overall form and shape of the body.
Choice C Reason: Provides reflexive responses to injuries
While the musculoskeletal system is involved in movement and support, reflexive responses to injuries are primarily mediated by the nervous system3. Reflex actions are automatic responses to stimuli that involve the spinal cord and peripheral nerves, not the musculoskeletal system directly.
Choice D Reason: Formation of blood cells through red or yellow marrow
The formation of blood cells, known as hematopoiesis, occurs in the bone marrow, which is part of the skeletal system. Red bone marrow is responsible for producing red blood cells, white blood cells, and platelets. Yellow bone marrow, primarily composed of fat cells, can also convert to red marrow if necessary to increase blood cell production.
Choice E Reason: Protection of soft organs
The musculoskeletal system plays a crucial role in protecting soft organs. For example, the rib cage protects the heart and lungs, the skull encases the brain, and the vertebrae shield the spinal cord. This protective function is vital for preventing injury to these essential organs.

Correct Answer is C
Explanation
Choice A Reason: Cerebral edema is caused by cerebrospinal fluid flowing from the intraventricular space to the interstitial area of the brain
This statement is not accurate. Cerebral edema in meningitis is not primarily caused by the flow of cerebrospinal fluid (CSF) from the intraventricular space to the interstitial area. Instead, it is more related to the inflammatory response triggered by the infection.
Choice B Reason: Cerebral edema is caused by osmotic cerebral edema
Osmotic cerebral edema occurs when there is an imbalance in the osmotic pressure, leading to fluid accumulation in the brain. However, this is not the primary mechanism in meningitis. The edema in meningitis is more related to the inflammatory response and the by-products of the pathogen.
Choice C Reason: Cerebral edema is caused by the by-products of the pathogen that causes the meningitis
This statement is the most accurate. In meningitis, the infection triggers an inflammatory response, leading to the release of various by-products such as cytokines and other inflammatory mediators. These substances increase the permeability of the blood-brain barrier, resulting in fluid leakage and cerebral edema.
Choice D Reason: Cerebral edema is caused by whole body inflammation which affects the brain the most
While systemic inflammation can contribute to cerebral edema, the primary cause in meningitis is the localized inflammatory response in the brain and meninges. The by-products of the pathogen and the resulting inflammation are the main factors leading to cerebral edema.
Correct Answer is B
Explanation
Choice A Reason:
Asking about the last physical exam is important for understanding the client’s overall health history, but it is not the most critical question for assessing the risk factors specific to Parkinson’s disease.
Choice B Reason:
This is the correct answer. Family history is a significant risk factor for Parkinson’s disease. Genetic factors can play a role in the development of the disease, and knowing if any family members have Parkinson’s can help in understanding the client’s risk and planning appropriate care.
Choice C Reason:
While occupational history can provide insights into potential environmental exposures that might contribute to Parkinson’s disease, it is not as directly relevant as family history in assessing the risk of developing the disease.
Choice D Reason:
The amount of coffee consumed daily is not directly related to the risk of developing Parkinson’s disease. Some studies suggest that caffeine might have a protective effect, but this is not a primary factor in assessing the disease.
