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:
Avoiding undercooked foods is generally good advice for preventing foodborne illnesses, but it is not specifically related to reducing the risk of peptic ulcers. Peptic ulcers are primarily caused by Helicobacter pylori infection and the use of nonsteroidal anti-inflammatory drugs (NSAIDs).
Choice B Reason:
There is no established link between hormone replacement therapy and an increased risk of peptic ulcers. The primary risk factors for peptic ulcers include H. pylori infection, NSAID use, smoking, and excessive alcohol consumption.
Choice C Reason:
This is the correct answer. Fried foods can irritate the stomach lining and increase the production of stomach acid, which can exacerbate the symptoms of peptic ulcers and potentially contribute to their development. Avoiding fried foods can help reduce irritation and promote healing.
Choice D Reason:
There is no evidence to suggest that decongestants for seasonal allergies or colds are linked to the development of peptic ulcers. The main contributors to peptic ulcers are H. pylori infection and NSAID use.
Correct Answer is ["A","B","C"]
Explanation
Choice A Reason: Superficial palpation
Superficial palpation is typically performed after auscultation to avoid altering bowel sounds. It involves gently pressing on the abdomen to detect tenderness, masses, or other abnormalities. This step helps in identifying areas that may require deeper examination.
Choice B Reason: Auscultation
Auscultation is performed after inspection and before palpation to listen to bowel sounds without interference. Using a stethoscope, the nurse listens for the presence, frequency, and character of bowel sounds. This step is crucial as palpation can stimulate bowel activity, potentially leading to inaccurate findings.
Choice C Reason: Inspection
Inspection is the first step in an abdominal assessment. The nurse visually examines the abdomen for any abnormalities such as distension, scars, or discoloration. This step provides initial information about the child’s abdominal health and helps guide the subsequent steps of the assessment.
Choice D Reason: Deep palpation
Deep palpation is performed last to assess the deeper structures of the abdomen. This step involves applying more pressure to feel for masses, organ size, and tenderness. It is important to perform this step last to avoid causing discomfort or altering the findings of the other assessment steps.
