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 B
Explanation
Choice A rationale
Administering a vasoconstrictor is a potential intervention for shock but it is not the first action. The client's hypotension and tachycardia are indicative of hypovolemic shock due to profuse vomiting, leading to fluid loss. The body's initial compensatory mechanism involves vasoconstriction to maintain blood pressure, so further constriction without addressing the volume deficit can worsen tissue perfusion.
Choice B rationale
The client is exhibiting signs of hypovolemic shock, including a low blood pressure of 86/58 mmHg, a high pulse of 114/min, and a high respiratory rate of 27/min. These are physiological compensations for reduced circulating blood volume. Increasing the intravenous infusion rate directly addresses the primary problem by rapidly replacing lost fluid volume, thereby increasing preload, stroke volume, cardiac output, and ultimately, blood pressure.
Choice C rationale
Elevating the client's feet can temporarily increase venous return to the heart and improve blood pressure. However, this is a passive measure that does not address the underlying fluid deficit causing the hypovolemic shock. It is a helpful adjunctive action but is not the definitive first-line intervention required to correct the circulatory collapse in this scenario.
Choice D rationale
Initiating oxygen therapy is a supportive measure for shock because it helps improve tissue oxygenation, which is compromised due to poor perfusion. While beneficial, it does not correct the root cause of the shock, which is the lack of circulating fluid volume. The most immediate and life-saving intervention is to restore fluid volume to improve cardiac output and blood pressure
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"A"}
Explanation
Why Safety Comes First
- The client presents with multiple red flags for physical abuse and neglect, including bruises in various stages of healing, a fracture, and concerning behavior around the adult child.
- Ensuring the client is in a safe environment is the top priority to prevent further harm and initiate protective interventions.
Why Nutritional Status Is Next
- The client reports limited food availability and has a low BMI (18.3), suggesting possible malnutrition.
- Addressing nutritional needs is essential for recovery and overall well-being, especially in older adults who are vulnerable to rapid health decline.
