Which of the following is not an effect of the drug isoflurane?

Correct Answer: A

Rationale: The correct answer is A: Elevated lipid levels. Isoflurane does not cause elevated lipid levels. Isoflurane is a general anesthetic that primarily affects the central nervous system, leading to effects like decreased respiratory function and increased blood flow to the brain. Nausea can also be a side effect of isoflurane due to its impact on the gastrointestinal system. However, there is no direct link between isoflurane and elevated lipid levels. Thus, choice A is the correct answer.

Correct Answer: D

Rationale: The correct answer is D: Hyperactivity. Clozapine is an antipsychotic drug used for schizophrenia treatment. Agranulocytosis is a known severe side effect of Clozapine. Hyperactivity is not a known effect of Clozapine, as it actually has a sedative effect due to its mechanism of action in the brain. Therefore, option D is the correct answer. Options A, B, and C are incorrect as agranulocytosis is a known side effect, Clozapine is an antipsychotic drug, and it is commonly used for schizophrenia treatment.

Correct Answer: A

Rationale: The correct answer is A: Renal disease. Epinephrine is not used to treat renal disease because it can potentially worsen kidney function. Epinephrine is used in asthma to dilate the airways, in hypotension to increase blood pressure, and in glaucoma to reduce intraocular pressure. Treating renal disease with epinephrine can lead to further complications due to its effect on blood flow and kidney function. Therefore, renal disease is not treated with epinephrine to avoid exacerbating kidney issues.

Correct Answer: A

Rationale: The correct answer is A: COPD. Ephedrine is a sympathomimetic drug that acts on alpha and beta adrenergic receptors, leading to vasoconstriction and increased heart rate. It is used to treat hypotension and congestion by increasing blood pressure and dilating airways, respectively. Incontinence is not typically treated with Ephedrine. However, COPD involves bronchoconstriction, which can worsen with Ephedrine due to its vasoconstrictive effects. Therefore, Ephedrine is not used to treat COPD.

Correct Answer: B

Rationale: Barbiturates are central nervous system depressants used to treat seizures, insomnia, and anxiety. However, they can worsen hypotension as they can cause vasodilation and decrease blood pressure. Choice B is correct because using barbiturates in hypotensive patients can lead to further lowering of blood pressure, potentially causing harm. Choices A, C, and D are incorrect as barbiturates are commonly used to treat seizures, insomnia, and anxiety, respectively, due to their sedative and anticonvulsant properties.
