A nurse is assessing a client who is experiencing a change in vision. Which of the following statements indicates that the client might be developing cataracts?

A. The client develops bradycardia and bradypnea: Bradycardia (slow heart rate) and bradypnea (slow breathing rate) may indicate a slowing down of bodily functions but are not typical manifestations of postoperative shock. In postoperative shock, the body's compensatory mechanisms often lead to tachycardia (rapid heart rate) and tachypnea (rapid breathing rate) as the body tries to maintain perfusion.

B. The client has metabolic alkalosis and warm extremities: Metabolic alkalosis and warm extremities are not typically associated with postoperative shock. In shock, metabolic acidosis is more common due to tissue hypoperfusion, and extremities may become cool due to peripheral vasoconstriction as the body attempts to shunt blood to vital organs.

C. The client has hypertension and anuria: Hypertension (high blood pressure) and anuria (lack of urine output) are not indicative of postoperative shock. In shock, blood pressure typically decreases (hypotension), and oliguria or anuria may occur due to decreased renal perfusion.

D. The client has hypotension and is confused: This is the correct answer. Hypotension (low blood pressure) is a hallmark sign of shock, indicating inadequate tissue perfusion. Confusion may occur due to cerebral hypoperfusion and inadequate oxygen delivery to the brain. Confusion is a late sign of shock and indicates severe compromise of organ perfusion.

A. "You can have 2 to 3 cups of coffee throughout the day": Caffeine consumption can exacerbate tinnitus symptoms in some individuals. Therefore, advising the client to limit caffeine intake, rather than specifying a quantity, would be more appropriate.

B. "You should practice deep breathing exercises": Deep breathing exercises and relaxation techniques can help reduce stress and anxiety, which may contribute to tinnitus symptoms. Stress management strategies can be beneficial in managing tinnitus-related distress.

C. "You can use at least 2,300 mg of sodium daily": High sodium intake may exacerbate tinnitus symptoms in some individuals. Advising the client to limit sodium intake would be more appropriate to potentially alleviate symptoms.

D. "You should avoid exercising": Regular exercise is generally beneficial for overall health and well-being, including stress reduction, which can help manage tinnitus symptoms. Therefore, advising the client to avoid exercising is not appropriate.
