Which of the following is not a known effect of the drug Clozapine?

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: 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.

Correct Answer: C

Rationale: The correct answer is C: Sedation. Opioid analgesics like dextromethorphan and methadone are primarily used for pain management, not sedation. They work by binding to opioid receptors in the brain to reduce pain perception. Pulmonary edema can be managed with diuretics, cough suppression with antitussives, and sedation with sedatives/hypnotics. Therefore, sedation is not a condition typically treated with opioid analgesics.

Correct Answer: C

Rationale: Hydrochlorothiazide is a diuretic commonly used to treat hypertension (HTN) and congestive heart failure (CHF) by reducing blood volume and lowering blood pressure. Nephritis is an inflammatory condition of the kidneys, not typically treated with Hydrochlorothiazide as it may worsen kidney function. Hypercalciuria, excessive calcium in the urine, can be managed with Hydrochlorothiazide as it helps reduce calcium excretion. Therefore, the correct answer is C (Nephritis), as it is not typically treated with Hydrochlorothiazide due to its potential impact on kidney function.
