Medical Surgical Assignment Exam HESI Quizlet

Correct Answer: B

Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.

Correct Answer: A

Rationale: The correct answer is High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps remove cholesterol from the arteries, reducing the risk of atherosclerosis. LDL (choice B) is considered 'bad' cholesterol as it can deposit cholesterol in the arteries, increasing the risk of atherosclerosis. VLDL (choice C) and IDL (choice D) are also associated with increased risk of atherosclerosis rather than decreasing it.

Correct Answer: B

Rationale: The correct answer is B: Metabolic alkalosis. Loss of gastric secretions can lead to metabolic alkalosis due to the loss of hydrochloric acid. This can result in an increase in blood pH levels. Respiratory acidosis (choice A) is caused by retention of carbon dioxide, not related to the loss of gastric secretions. Hypoglycemia (choice C) is a low blood sugar level and is not directly related to the loss of gastric secretions. Hyperkalemia (choice D) is an elevated potassium level in the blood and is not typically associated with the loss of gastric secretions.

Correct Answer: B

Rationale: A history of cerebrovascular hemorrhage is a contraindication for tPA therapy due to the risk of bleeding. Choice A is incorrect because treating hypoglycemia with an oral hypoglycemic agent is not a contraindication for tPA therapy. Choice C is incorrect as age and family history of MI do not contraindicate the use of tPA. Choice D is incorrect as being intolerant of medication containing aspirin is not a contraindication for tPA therapy.
