A client with acute heart failure is receiving dobutamine. What is the desired effect of this drug in a patient with heart failure?

Choice A reason: Hypokalemia, or low potassium levels, is not typically expected in clients with extensive burn injuries. In fact, during the acute phase of burn injury, hyperkalemia is more common due to the release of potassium from damaged cells and the impairment of kidney function.

Choice B reason: Metabolic alkalosis is not a common finding in clients with extensive burns. Instead, metabolic acidosis is more likely due to the increased production of lactic acid from tissue hypoxia and impaired perfusion. Burn injuries can lead to significant fluid and electrolyte shifts, but metabolic alkalosis is not the usual result.

Choice C reason: Low hemoglobin can occur in burn patients due to fluid shifts and the loss of red blood cells from the injury itself. However, it is not the most characteristic laboratory finding associated with extensive burns compared to hyperkalemia.

Choice D reason: Hyperkalemia is the expected laboratory result in clients with extensive burn injuries. Burns cause massive cell destruction, leading to the release of intracellular potassium into the bloodstream. Additionally, impaired kidney function in the acute phase can further contribute to elevated potassium levels, making hyperkalemia a common and critical concern in burn patients.

Choice A reason: Not needing vascular access to perform PD is a significant advantage for patients. Peritoneal dialysis uses the peritoneal membrane in the abdomen as a filter to clean the blood, which eliminates the need for vascular access, such as fistulas or catheters required in hemodialysis. This can reduce the risks associated with vascular access, such as infections and complications related to surgical procedures.

Choice B reason: Being able to perform PD in the comfort of one's home is a major benefit. Patients can manage their dialysis treatments at home, which offers more convenience and flexibility compared to traveling to a dialysis center for hemodialysis sessions. This can greatly improve the quality of life and reduce the burden of frequent trips to healthcare facilities.

Choice C reason: Stating that there is no risk for infection with PD is inaccurate. While PD offers many benefits, it does carry a risk of peritonitis, an infection of the peritoneal cavity. Patients must be educated on proper technique and hygiene to minimize this risk. Hence, this statement is not accurate and should not be included as an advantage.

Choice D reason: Having flexibility in when to do the exchanges is another benefit of PD. Patients can schedule their dialysis exchanges at times that best fit their lifestyle and daily routines. This flexibility allows for greater independence and freedom compared to the fixed schedules required for in-center hemodialysis.

Choice E reason: PD can take less time than hemodialysis treatments, especially when considering travel and waiting times associated with in-center hemodialysis. Although the actual dialysis process for PD requires regular exchanges throughout the day or night, it integrates more seamlessly into daily life, making it a time-efficient option for many patients.
