HESI Medical Surgical Exam

Correct Answer: A

Rationale: The most important nursing action when administering a blood transfusion is monitoring the patient's blood pressure. This is crucial because monitoring blood pressure allows for the prompt identification of any signs of adverse transfusion reactions, such as transfusion reactions or fluid overload. Immediate intervention can be initiated if any complications arise. While monitoring temperature, heart rate, and oxygen saturation are also essential aspects of patient care, they are not as critical as blood pressure monitoring during a blood transfusion. Therefore, the correct answer is to monitor the patient's blood pressure.

Correct Answer: A

Rationale: The correct answer is A: Metabolic alkalosis. Loss of gastric secretions, which contain stomach acid, can lead to metabolic alkalosis. Excessive loss of acid results in an increase in the blood pH, leading to alkalosis. Hyperkalemia (B) is an elevated potassium level and is not directly related to the loss of gastric secretions. Metabolic acidosis (C) is an acid-base imbalance characterized by low pH and bicarbonate levels, which is the opposite of what would occur with the loss of gastric secretions. Hypoglycemia (D) is low blood sugar and is not typically associated with the scenario described in the question.

Correct Answer: A

Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.

Correct Answer: A

Rationale: In the staging process of Hodgkin's disease, Stage I signifies the involvement of a single lymph node. This stage indicates localized disease with the disease being limited to a single lymph node or a group of adjacent nodes. Choices B, C, and D are incorrect because they describe more extensive involvement of lymph nodes, both sides of the diaphragm, or extralymphatic organs, which would correspond to higher stages in the staging system.
