ATI Pharmacology Proctored Questions
Question 1 of 5
A healthcare provider is assessing a client who is taking levothyroxine. The healthcare provider should recognize that which of the following findings is a manifestation of levothyroxine overdose?
Correct Answer: A
Rationale: Insomnia is a common symptom of levothyroxine overdose due to excessive stimulation of the central nervous system. Levothyroxine is a thyroid hormone replacement medication, and an overdose can lead to hyperthyroidism symptoms, including insomnia. Constipation and drowsiness are not typically associated with levothyroxine overdose. Hypoactive deep-tendon reflexes are more indicative of hypothyroidism rather than an overdose of levothyroxine.
Question 2 of 5
A drug ending in the suffix (pril) is considered a ______.
Correct Answer: B
Rationale: Drugs with names ending in -pril are classified as angiotensin-converting enzyme (ACE) inhibitors. These medications are commonly used to manage conditions like high blood pressure, heart failure, and diabetic kidney disease by blocking the conversion of angiotensin I to angiotensin II, leading to vasodilation and decreased blood pressure.

Question 4 of 5
Which of the following is the antidote for benzodiazepine toxicity?
Correct Answer: A
Rationale: Flumazenil is the specific antidote for benzodiazepine toxicity. It acts as a competitive antagonist at the benzodiazepine binding site on the GABA receptor, reversing the sedative effects of benzodiazepines. Administration of flumazenil is indicated in cases of benzodiazepine overdose or toxicity to rapidly reverse the central nervous system depression caused by these drugs. It is important to note that flumazenil should be used cautiously in patients with a history of seizures or those who are physically dependent on benzodiazepines, as it can precipitate withdrawal symptoms or seizures.
Question 5 of 5
Which of the following conditions is not treated with Ephedrine?
Correct Answer: A
