1. Which of the following is not an effect of the drug isoflurane?
- A. Elevated lipid levels
- B. Nausea
- C. Increased blood flow to the brain
- D. Decreased respiratory function
Correct answer: A
Rationale: Isoflurane is not known to cause elevated lipid levels. Common effects of isoflurane include nausea, increased blood flow to the brain, and decreased respiratory function. Elevated lipid levels are not typically associated with the administration of isoflurane, making choice A the correct answer.
2. Which of the following is not related to drug toxicity of Atenolol?
- A. CHF
- B. Tachycardia
- C. AV block
- D. Sedative appearance
Correct answer: B
Rationale: Atenolol, a beta-blocker, is not typically associated with tachycardia. Instead, drug toxicity of Atenolol is more commonly linked to bradycardia due to its beta-blocking effects on the heart's electrical conduction system. Symptoms of Atenolol toxicity may include heart failure (CHF), AV block, and a sedative appearance, but not tachycardia.
3. Which of the following conditions is not treated with epinephrine?
- A. Renal disease
- B. Asthma
- C. Hypotension
- D. Glaucoma
Correct answer: A
Rationale: Epinephrine is not used to treat renal disease. Epinephrine is commonly used to treat conditions like asthma, hypotension, and glaucoma, but it is not an appropriate treatment for renal disease. Renal disease requires specific management strategies that do not involve the use of epinephrine.
4. Which of the following conditions is not treated with Dexamethasone?
- A. Inflammation
- B. Asthma
- C. Addison’s disease
- D. Wilson’s disease
Correct answer: D
Rationale: Dexamethasone is not used to treat Wilson’s disease. It is a corticosteroid primarily used for conditions like inflammation, asthma, and Addison’s disease. Wilson’s disease is a genetic disorder involving copper accumulation and is treated with medications like chelating agents or zinc salts, not Dexamethasone.
5. Which of the following is the antidote for benzodiazepine toxicity?
- A. Flumazenil
- B. Methylene blue
- C. Deferoxamine
- D. Alkalinize urine
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.
