The nurse is caring for a patient with an injury to the frontal lobe of the brain. Which sign or symptom would the nurse expect?

A. Steppage: This gait involves lifting the knee high to avoid dragging the toes, commonly seen in patients with peroneal nerve injury. It is a compensatory movement for weakness in dorsiflexion rather than a shuffling or stooped posture. It does not involve difficulty with starting or stopping.

B. Cerebellar ataxia: This is a staggering, wide-based gait where the patient appears uncoordinated and may sway significantly from side to side. It is caused by cerebellar dysfunction and often includes a positive Romberg test. It lacks the shuffling characteristics associated with basal ganglia disorders.

C. Spastic hemiparesis: This gait involves one arm held immobile against the body, while the affected leg is stiff and dragged in a semi-circle. It typically follows a stroke and affects only one side of the body. It does not present with the symmetrical shuffling steps seen here.

D. Parkinsonian: This gait is characterized by a stooped posture, trunk leaning forward, and short, shuffling steps where the feet barely leave the ground. The patient often experiences "freezing" when trying to initiate walking or change direction. It results from dopamine depletion affecting the extrapyramidal motor system.

A. Cutaneous pain: This pain originates from the superficial skin layers or subcutaneous tissues and is typically sharp or burning. It is localized to the site of stimulation, such as a laceration or a minor thermal burn. It does not explain the radiating discomfort from a deep internal organ like the heart.

B. Referred pain: This phenomenon occurs when pain is perceived at a site different from its actual biological point of origin. Sensory fibers from the viscera and somatic structures enter the spinal cord at the same segmental level. The brain misinterprets the visceral signals from the myocardium as coming from the neck or arm.

C. Somatic pain: Deep somatic pain arises from sources such as blood vessels, joints, tendons, muscles, and bone. It is usually described as a dull, aching sensation that is better localized than visceral pain. It involves the musculoskeletal framework rather than the autonomic sensory pathways associated with cardiac ischemia.

D. Visceral pain: This pain originates from the larger internal organs, such as the stomach, intestine, or the heart itself. While the underlying cause of a myocardial infarction is visceral, the specific report of neck and arm pain describes the secondary perception. The term referred pain more accurately describes the location-based clinical manifestation.
