Adult Health Nursing Quizlet Final

Correct Answer: B

Rationale: Metformin is a commonly prescribed medication for the treatment of type 2 diabetes mellitus. One of the rare but serious adverse effects associated with metformin use is lactic acidosis. Lactic acidosis results from the buildup of lactic acid in the bloodstream, leading to symptoms such as weakness, rapid breathing, abdominal pain, and muscle pain. Lactic acidosis can be life-threatening and requires immediate medical attention. It is important for patients taking metformin to be aware of the signs and symptoms of lactic acidosis and seek immediate medical help if they experience any of these symptoms. Regular monitoring of kidney function is crucial in patients taking metformin to reduce the risk of lactic acidosis.

Correct Answer: C

Rationale: Humoral immunity is primarily responsible for protecting against infections by pathogens like viruses. In the case of the hepatitis B virus (HBV), the individual is exposed to the virus and develops immunity, which is typically mediated by antibodies produced by B cells. These antibodies circulate in the blood and can neutralize the virus, preventing future infections. This type of immunity is known as humoral immunity, as it involves the production of antibodies that target specific antigens, such as those present on the surface of the hepatitis B virus. In contrast, passive immunity is when antibodies are transferred from an external source, innate immunity provides immediate, non-specific defenses against pathogens, and cell-mediated immunity involves the activation of T cells to combat intracellular pathogens.

Correct Answer: A

Rationale: The most appropriate intervention for managing hepatic encephalopathy in this patient receiving palliative care for end-stage liver disease is to administer lactulose or other ammonia-lowering agents to reduce ammonia levels. Hepatic encephalopathy is believed to be primarily caused by the accumulation of ammonia in the bloodstream due to compromised liver function. Lactulose works by acidifying the gut lumen, which facilitates the excretion of ammonia in the form of ammonium ions. By reducing ammonia levels, hepatic encephalopathy symptoms, such as confusion and altered mental status, can be improved. Initiating other supportive measures like managing precipitating factors, maintaining hydration, and addressing nutritional issues should also be part of the holistic approach in managing hepatic encephalopathy in palliative care. However, addressing the underlying cause by reducing ammonia levels with lactulose is the priority intervention in this scenario.

Correct Answer: C

Rationale: The most appropriate nursing action for managing a patient with dependent edema in the lower extremities is to administer diuretics as prescribed. Diuretics help the body remove excess fluid, reducing swelling and edema in the extremities. It is important to follow the healthcare provider's orders for administering diuretics to ensure the patient's fluid balance is managed effectively. While elevating the legs above heart level and applying compression stockings may provide temporary relief, addressing the underlying cause of fluid retention with diuretics is essential for long-term management of the edema in a patient with heart failure. Encouraging increased fluid intake would not be appropriate in this case, as the focus should be on reducing fluid overload rather than increasing fluid intake.

Correct Answer: D

Rationale: Before any procedure, it is crucial to ensure that you have the proper authorization and guidelines in place. By checking the physician's order and the patient care plan, you confirm that suctioning is indeed needed and that you follow the specific instructions for that patient. This step helps ensure patient safety and effective care delivery. Once you have verified this information, you can proceed with gathering equipment, performing hand hygiene, and assessing the patient's condition as necessary.
