A nurse is providing teaching about client rights to a client who has a brain tumor. Which of the following client statements indicates an understanding of the teaching?

D. Morphine is effective in reducing anxiety due to its sedative and anxiolytic properties. Decreased anxiety can be an indication that morphine is effective in managing symptoms associated with acute heart failure, such as dyspnea and anxiety related to difficulty breathing.

A Morphine is a potent opioid analgesic that can depress the respiratory center, leading to decreased respiratory rate or even respiratory depression in some cases.

B. Vomiting after morphine administration does not indicate effectiveness of the medication in managing acute heart failure symptoms. It is rather a side effect that needs to be managed.

C. Decreased urinary output is not a sign of effectiveness in managing acute heart failure symptoms. It is an adverse effect that needs to be monitored and managed separately.

Fluid volume deficit

The client is receiving Furosemide (a diuretic) at a significant dose (80 mg IV three times per day). This medication promotes diuresis to reduce fluid overload in heart failure. The client's weight decreased from 97.5 kg on admission to 90.7 kg on Day 2, indicating a fluid loss of approximately 6.8 kg (about 15 pounds). This substantial weight loss suggests a risk for fluid volume deficit, which can lead to hypovolemia and potential complications such as hypotension and decreased tissue perfusion.

Acute kidney injury (AKI)

The client's BUN level increased from 10 mg/dL on admission to 20 mg/dL on Day 2, which suggests impaired kidney function. This change may indicate a decrease in glomerular filtration rate due to decreased renal perfusion secondary to fluid loss from diuresis. AKI is a known complication in heart failure patients receiving diuretic therapy, especially if there is inadequate monitoring and adjustment of diuretic doses.
