A nurse is assessing a client who is postpartum and has developed endometritis.
Which of the following findings should the nurse expect?

Choice A rationale

Chilling the lavage fluid causes vasoconstriction of the gastric blood vessels, which helps to slow or stop the bleeding. The cold temperature directly constricts the capillaries and arterioles in the stomach lining, reducing blood flow to the bleeding site. This action is a primary goal of gastric lavage in cases of upper gastrointestinal hemorrhage.

Choice B rationale

Positioning the client on their left side is the appropriate action. This position allows the lavage fluid to pool in the greater curvature of the stomach, where it can be most effective at washing over the bleeding site. Placing the client on their right side would cause the fluid to quickly pass into the duodenum, which is less effective for gastric lavage.

Choice C rationale

Gastric lavage is performed to remove blood and clots from the stomach. The procedure involves instilling a fluid, typically saline, and then withdrawing it. The nurse continues this process, manually withdrawing the fluid, until the return fluid is clear or only slightly pink, which indicates that the bleeding has been controlled or significantly reduced.

Choice D rationale

A large-bore NG tube (16-18 French or larger) is preferred for gastric lavage in cases of upper gastrointestinal bleeding. A large-bore tube is necessary to effectively remove blood clots and viscous fluid from the stomach. A small-bore tube would easily become occluded by clots, rendering the lavage procedure ineffective. *.

Choice A rationale

A healthcare surrogate, or proxy, is a person designated by the patient themselves through a legal document called a durable power of attorney for healthcare. The provider's role is to provide medical care, not to make legal decisions for the patient. The patient retains the autonomy to choose who will make decisions for them when they are unable to do so. This is a fundamental principle of patient self-determination and legal rights.

Choice B rationale

A patient's competency can fluctuate. In situations of temporary incapacity, such as during a surgical procedure with anesthesia or a period of severe illness, a health care surrogate may make decisions. However, once the patient regains competency and is able to make informed decisions for themselves, they automatically resume control of their health care. This is a core tenet of patient autonomy and the purpose of advance directives.

Choice C rationale

A healthcare surrogate does not have to be a family member. The person designated by the patient can be a friend, a partner, or any trusted individual. The only requirement is that the surrogate is an adult who is willing and able to make healthcare decisions on the patient's behalf. It is a legal designation, not a familial one, that is based on the patient's trust and personal wishes.

Choice D rationale

A provider is legally and ethically obligated to follow a patient's wishes as outlined in their advance directives, as long as those wishes are within the bounds of standard medical practice and are not medically futile. To go against a patient's documented wishes would be a violation of patient autonomy and a breach of the legal protections afforded by advance directives.
