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.

Related Questions
Correct Answer is D
Explanation
Choice A Reason: I will call your provider so we can discuss it
While this response shows the nurse’s willingness to involve the healthcare provider, it does not directly address the client’s concern about their ability to manage the prosthesis. It is important to provide immediate reassurance and encouragement to the client, which this response lacks.
Choice B Reason: What are you thinking that you would like to do?
This response is open-ended and encourages the client to express their feelings and thoughts. While it is a good approach to understand the client’s perspective, it does not provide the immediate reassurance and encouragement that the client needs to feel confident about managing the prosthesis.
Choice C Reason: You have the right to refuse if you don’t think you can do this
This response acknowledges the client’s autonomy but may inadvertently reinforce their doubts and fears about managing the prosthesis. It is important to encourage and support the client rather than focusing on their right to refuse.
Choice D Reason: Many clients your age are able to adjust surprisingly well to a prosthesis
This response is the most appropriate as it provides reassurance and encouragement to the client. By sharing that many clients of a similar age have successfully adjusted to a prosthesis, the nurse helps to build the client’s confidence and reduce their anxiety about managing the new situation. This positive reinforcement can be very motivating for the client.
Correct Answer is B
Explanation
Choice A Reason:
This option suggests removing the mask before removing gloves. However, the correct procedure is to remove gloves first, followed by the mask, to prevent contamination from the gloves to the face.
Choice B Reason:
This is the correct answer. Medical masks should be discarded after each use to prevent contamination and ensure effectiveness. Reusing masks can lead to the spread of pathogens.
Choice C Reason:
While positioning the mask correctly is important, the statement contains an error. The flexible metal piece should be at the top of the mask, not the bottom.
Choice D Reason:
Touching the front of the mask while wearing it is incorrect as it can lead to contamination. The front of the mask is considered contaminated, and touching it can transfer pathogens to the hands.
