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. The client whose mother and uncle were diagnosed with this same condition: Hypertrophic cardiomyopathy (HCM) often has a genetic component, with a familial predisposition observed in many cases. Individuals with a family history of HCM, especially in first-degree relatives such as parents or siblings, are at higher risk of developing the condition due to genetic factors.

B. The client who is recovering from a recent illness that caused vomiting and diarrhea: Acute illnesses such as vomiting and diarrhea can lead to dehydration, electrolyte imbalances, and transient changes in cardiac function. While dehydration and electrolyte imbalances may exacerbate symptoms in individuals with existing cardiac conditions, they are not primary risk factors for developing hypertrophic cardiomyopathy (HCM).

C. The client who is out of work and has been experiencing increased stress: Chronic stress and psychosocial factors may contribute to the progression of cardiovascular disease in general, but they are not specific risk factors for developing hypertrophic cardiomyopathy (HCM).

D. The client who uses oxygen at night to treat obstructive sleep apnea: While obstructive sleep apnea is associated with cardiovascular complications, including hypertrophic cardiomyopathy (HCM), the use of oxygen therapy at night to treat sleep apnea does not directly increase the risk of developing HCM. However, untreated obstructive sleep apnea may lead to chronic hypoxia and other cardiac issues over time.

A. "I stopped taking aspirin last week.": Stopping aspirin medication prior to surgery is often advised to reduce the risk of bleeding during and after the procedure. The nurse may confirm the timing of discontinuation with the client and verify if any other anticoagulant medications are being taken.

B. "I did not put my contact lenses in this morning.": Removing contact lenses before surgery is a routine precaution to prevent potential corneal abrasions or complications during the procedure. This statement indicates the client is following preoperative instructions.

C. "I took my blood pressure meds with a sip of water.": Taking blood pressure medications with a small amount of water is generally acceptable before surgery. However, the nurse may verify the specific medications the client is taking and their dosing schedule to ensure compliance.

D. "I had a cough and runny nose a couple days ago.": This statement requires further investigation as respiratory symptoms, such as cough and runny nose, may indicate an underlying respiratory infection. Infections can increase the risk of complications during surgery, such as anesthesia-related respiratory issues or postoperative infections. The nurse should assess the severity and duration of the symptoms, inquire about any fever or recent exposure to illnesses, and consider notifying the surgical team for further evaluation and decision-making regarding the client's surgical readiness.
