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)

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.

Choice A Reason:

Droplet transmission involves the spread of pathogens through respiratory droplets expelled when an infected person coughs or sneezes. Staphylococcus aureus is not typically spread this way.

Choice B Reason:

This is the correct answer. Indirect contact transmission occurs when a person touches a contaminated object or surface, such as a towel, and then touches their own body, allowing the bacteria to enter through breaks in the skin or mucous membranes.

Choice C Reason:

Vector transmission involves the spread of pathogens through insects or animals, such as mosquitoes or ticks. Staphylococcus aureus is not transmitted by vectors.

Choice D Reason:

Airborne transmission involves the spread of pathogens through the air over long distances, typically via tiny droplets that remain suspended in the air. Staphylococcus aureus is not commonly spread through airborne transmission.
