A nurse is teaching a client who has cardiomyopathy about the side effects of their new prescription beta blocker, carvedilol. Which of the following client statements should indicate to the nurse that the client understands the teaching? (select all that apply)

A. The aortic and mitral valves are the most commonly replaced valves: This statement is accurate. The aortic and mitral valves are indeed the most commonly replaced valves in cardiac valve replacement surgeries. Aortic valve replacement is commonly performed for conditions such as aortic stenosis or regurgitation, while mitral valve replacement is often indicated for mitral regurgitation or stenosis.

B. Mitral valve insufficiency occurs during the diastolic phase of the cardiac cycle: This statement is incorrect. Mitral valve insufficiency, also known as mitral regurgitation, occurs during the systolic phase of the cardiac cycle. It involves the backflow of blood from the left ventricle into the left atrium during ventricular systole, leading to volume overload of the left atrium and potentially causing symptoms such as dyspnea and fatigue.

C. Inadequate closure of the tricuspid valve causes overload in the left ventricle: This statement is incorrect. Inadequate closure of the tricuspid valve leads to regurgitation of blood from the right ventricle back into the right atrium during ventricular systole. This condition, known as tricuspid regurgitation, causes volume overload in the right atrium and ventricle, rather than overload in the left ventricle.

D. Aortic stenosis increases right ventricular systolic pressure and decreases afterload: This statement is partially correct. Aortic stenosis indeed increases left ventricular systolic pressure and decreases afterload, not right ventricular pressure. The increased afterload on the left ventricle can lead to left ventricular hypertrophy and eventually heart failure. However, aortic stenosis does not directly affect right ventricular systolic pressure.

A) Hypoxia and acidosis While hypoxia and acidosis are serious complications of shock, they are physiological rather than psychological outcomes. These conditions primarily affect the body's metabolic and respiratory functions, rather than mental health or behavior.

B) Hearing deficits and increased risk of glaucoma Hearing deficits and increased risk of glaucoma are potential complications associated with certain medical conditions or medications but are not directly related to the psychological outcomes of shock. These conditions affect sensory perception (hearing and vision) rather than mental health or behavior.

C) Bipolar behaviors and schizotypal behaviors Bipolar behaviors and schizotypal behaviors are manifestations of mood and psychotic disorders, respectively, and are not typical adverse outcomes of shock. While psychological disturbances can occur in critically ill patients, they are not commonly characterized by specific psychiatric diagnoses like bipolar or schizotypal behaviors.

D) Disorientation and depression Disorientation and depression are common adverse psychological outcomes experienced by patients who have spent an extended period in the intensive care unit (ICU) due to complications related to shock. Prolonged ICU stays, medical interventions, sedation, and physical discomfort can contribute to feelings of confusion, disorientation, and depression in patients. Therefore, it is essential for the nurse to educate the client about these potential psychological effects and provide appropriate support and resources to address them during the transition to the medical unit.
