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

Answer and Explanation

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 D

Explanation

Choice A Reason:

An N95 respirator is used for airborne precautions, not contact precautions. It is necessary for protecting against airborne pathogens like tuberculosis or COVID-19.

Choice B Reason:

Goggles are used to protect the eyes from splashes or sprays of infectious materials. While they can be part of contact precautions, they are not the primary PPE required for changing bed linen.

Choice C Reason:

A face shield provides protection against splashes and sprays to the face. Similar to goggles, it is not the primary PPE required for contact precautions when changing bed linen.

Choice D Reason:

This is the correct answer. Gloves are essential for contact precautions to prevent the transmission of infectious agents through direct or indirect contact with contaminated surfaces or materials. They protect the nurse from coming into contact with pathogens that may be present on the bed linen.

A. Superficial palpation B. Auscultation C. Inspection D. Deep palpation

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.
