Endocrine System Practice Questions Questions
Question 1 of 5
Which of the following is the most reliable thyroid function test to diagnose hyperthyroidism in an older adult?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A nurse is taking care of a client with diabetes who is experiencing diabetic ketoacidosis (DKA). The nurse knows that DKA is a type of what acid-base imbalance?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The nurse assesses an older client. What age-related physiologic changes would the nurse expect?
Correct Answer: C
Rationale: The correct answer is C: Dehydration. As people age, their body's ability to conserve water decreases, making older adults more prone to dehydration. Age-related physiologic changes such as decreased thirst sensation and reduced kidney function contribute to this. Heat intolerance (A) is not a common age-related change. Rheumatoid arthritis (B) is an autoimmune condition not directly associated with aging. Increased appetite (D) can occur due to various factors but is not a consistent age-related change. Overall, C is the most likely physiological change in older adults due to their altered fluid balance mechanisms.
Question 4 of 5
A child overdoses on a drug that affects both the autonomic and somatic nervous systems. As blood level of the drug rises, he experiences hypertension and tachycardia, accompanied by skeletal muscle tremor. Further elevations of the drug cause all the expected signs and symptoms of autonomic ganglionic blockade, plus weakness and eventual paralysis of skeletal muscle. Which of the following drugs did the child most likely ingest?
Correct Answer: B
Rationale: The correct answer is B: Nicotine. Nicotine affects both the autonomic and somatic nervous systems. Initially, the child experiences hypertension, tachycardia, and skeletal muscle tremor due to stimulation of both systems. As the blood level rises, autonomic ganglionic blockade occurs, leading to weakness and paralysis. Bethanechol (A) is a cholinergic agonist, unlikely to cause these symptoms. Pilocarpine (C) is also a cholinergic agonist but does not affect the somatic nervous system. Scopolamine (D) is an anticholinergic drug, which would not cause the symptoms described.
Question 5 of 5
A 38-year-old farmer is brought to the emergency room by his wife with symptoms of sudden difficulty breathing, sweatiness, and anxiety. He was spraying insecticide when this happened. It has been 25 minutes since the symptoms started. The patient is emergently intubated and given atropine and another medication that acts to reactivate acetylcholinesterase. What medication is it?
Correct Answer: C
Rationale: The correct answer is C: Pralidoxime. Pralidoxime is used to reactivate acetylcholinesterase in cases of organophosphate poisoning, which is likely the cause of the patient's symptoms after spraying insecticide. Reactivating acetylcholinesterase helps to break down excess acetylcholine, reducing the toxic effects of the insecticide. Physostigmine (choice A) is an acetylcholinesterase inhibitor, which would worsen the patient's condition. Propranolol (choice B) is a beta-blocker and does not address the underlying issue of acetylcholinesterase inhibition. Phenylephrine (choice D) is a sympathomimetic drug used for vasoconstriction and would not be appropriate in this scenario.
