A nurse is planning to perform gastric lavage for a client who has upper gastrointestinal bleeding.
Which of the following actions should the nurse take.
Chill the lavage fluid before instilling it.
Position the client on his right side.
Withdraw the fluid manually until it is clear.
Insert a small-bore NG tube.
The Correct Answer is C
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. *.

Correct Answer is ["A","D","E","F","G"]
Explanation
The nurse should plan to include the following five findings in the report to the social worker, as they raise significant concern for elder maltreatment:
Findings to Include
• A. Client’s report of lack of access to bank accounts → Suggests financial exploitation, especially since the client gives income to the adult child but cannot access funds.
• D. Numerous bruises in various stages of healing → Strong indicator of physical maltreatment, possibly repeated trauma over time.
• E. Client’s report of lack of food in the house → Points to neglect, particularly in meeting basic nutritional needs.
• F. Client’s strong body odor → Suggests neglect in hygiene and personal care.
• G. Right arm fracture → A confirmed injury that, in context with other findings, may not align with a simple accidental fall.
Findings Not Prioritized for Reporting
• B. Client’s avoidance of eye contact → May reflect fear or discomfort, but is not specific enough to confirm maltreatment.
• C. Client’s report of weight loss → While potentially concerning, it wasn’t documented in the case and lacks supporting data like previous weight or timeframe.
Correct Answer is D
Explanation
Choice A rationale
Crusting along the incision line is the result of dried serous fluid and blood, which is a normal part of the wound healing process during the inflammatory phase. This finding alone is not indicative of a surgical site infection, which is characterized by other signs.
Choice B rationale
A temperature of $37.2^\circ C$ ($99^\circ F$) is within the normal range for body temperature ($36.1^\circ C$ to $37.2^\circ C$ or $97^\circ F$ to $99^\circ F$). An elevated temperature, specifically a fever, is a systemic sign of infection. A low-grade fever might be a subtle sign, but this temperature is not high enough.
Choice C rationale
Pink coloration of the incision line is a normal finding in the early stages of wound healing, representing angiogenesis, the formation of new blood vessels. This process is crucial for tissue repair and does not indicate a surgical site infection, which is typically characterized by erythema and warmth.
Choice D rationale
Swelling, or edema, is a classic sign of inflammation and infection. While some minor swelling is normal, swelling that extends significantly beyond the wound margins, such as 3.8 cm (1.5 in), indicates a heightened inflammatory response potentially due to bacterial proliferation and infection. *.
