A nurse is reinforcing teaching to a group of nursing students about causes of traumatic brain injuries (TBIs). Which of the following should the nurse include in the teaching? (Select All that Apply.)

A. Varicose veins: Varicose veins are dilated, twisted veins that commonly occur in the legs and are typically associated with venous insufficiency or venous valve dysfunction rather than valvular dysfunction of the heart.

B. Heart murmur: This is the correct answer. Valvular dysfunction can result in abnormal blood flow patterns across the heart valves, leading to turbulent blood flow and the production of audible heart murmurs upon auscultation.

C. Palpitations: Palpitations, or the sensation of rapid, pounding, or irregular heartbeats, can occur with valvular dysfunction, particularly if the dysfunction leads to alterations in heart rhythm or cardiac output.

D. Abdominal pain: Abdominal pain is not typically associated with valvular dysfunction. It may be a symptom of various gastrointestinal or abdominal conditions, but it is not a direct manifestation of valvular heart disease.

E. Chest pain: This is the correct answer. Chest pain can occur with valvular dysfunction, especially if the dysfunction leads to inadequate blood flow to the heart muscle (ischemia), which can cause angina or chest discomfort.

A. Restlessness: Restlessness is a common behavioral manifestation in clients with Alzheimer's disease. It can be caused by various factors, including confusion, agitation, discomfort, or unmet needs. Restlessness may manifest as pacing, fidgeting, or difficulty sitting still.

B. Aggression: Aggression, including verbal or physical aggression, is a behavioral manifestation that can occur in clients with Alzheimer's disease. Aggression may result from frustration, confusion, fear, or other underlying factors. It can present challenges for both the individual with Alzheimer's and their caregivers.

C. Depression: Depression is a mood disorder that can occur in individuals with Alzheimer's disease. Symptoms of depression may include persistent sadness, feelings of hopelessness, social withdrawal, and loss of interest in previously enjoyed activities. Depression can exacerbate cognitive decline and functional impairment in individuals with Alzheimer's.

D. Hyperactivity: Hyperactivity, characterized by excessive or restless activity, can occur in some individuals with Alzheimer's disease. Hyperactivity may be a manifestation of agitation, anxiety, or other underlying factors. It can present challenges for caregivers and may require interventions to manage.

E. Lethargy: Lethargy, or extreme fatigue and lack of energy, can also occur in individuals with Alzheimer's disease. Lethargy may result from physical and cognitive decline, medication side effects, depression, or other medical conditions. It can contribute to decreased engagement in activities and worsening of cognitive function.
