Nokea
A drug ending in the suffix (navir) is considered a ______.
- A. Antidepressant
- B. Protease inhibitor
- C. Beta antagonist
- D. H antagonist
Correct Answer: B
Rationale: The correct answer is B: Protease inhibitor. Drugs ending in the suffix (navir) are commonly used to inhibit protease enzymes in viruses, particularly in the treatment of HIV/AIDS. Protease inhibitors disrupt viral replication by preventing the cleavage of viral proteins, thus inhibiting the production of new infectious viral particles.
Choice A, Antidepressant, is incorrect as drugs used to treat depression usually end in (ine) or (pram).
Choice C, Beta antagonist, is incorrect as drugs affecting beta receptors typically end in (olol) or (lol).
Choice D, H antagonist, is incorrect as drugs targeting histamine receptors usually end in (ine) or (idine).

Which of the following is not a side effect associated with Prednisone toxicity?
- A. Cataracts
- B. Hypotension
- C. Psychosis
- D. Acne
Correct Answer: B
Rationale: The correct answer is B: Hypotension. Prednisone toxicity typically causes hypertension, not hypotension. Prednisone can lead to increased blood pressure due to its sodium-retaining effects. Cataracts (A), Psychosis (C), and Acne (D) are all known side effects of Prednisone toxicity. Cataracts can form due to long-term steroid use, psychosis can occur especially at higher doses, and acne is a common skin side effect. Therefore, hypotension is the odd one out among the choices given.
Which of the following conditions is not treated with Nifedipine?
- A. Angina
- B. Arrhythmias
- C. Hypertension
- D. Fluid retention
Correct Answer: D
Rationale: Nifedipine is a calcium channel blocker primarily used to treat angina, arrhythmias, and hypertension due to its vasodilatory effect. However, it does not treat fluid retention as it does not have diuretic properties. Therefore, the correct answer is D. Choice A, B, and C are incorrect because nifedipine is commonly used to manage these conditions.
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: Explanation: Dexamethasone is a corticosteroid used to treat inflammation and conditions like asthma and Addison's disease, which involve inflammation or immune responses. Wilson's disease is a genetic disorder related to copper metabolism, not treated with Dexamethasone. Dexamethasone could worsen Wilson's disease due to its potential impact on copper levels.
Which of the following conditions is not treated with Ephedrine?
- A. COPD
- B. Hypotension
- C. Congestion
- D. Incontinence
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.
Which of the following conditions is not treated with Prednisone?
- A. Cushing's disease
- B. Testicular cancer
- C. Lymphomas
- D. Chronic leukemias
Correct Answer: B
Rationale: Prednisone is a corticosteroid used to treat inflammatory conditions and certain types of cancer. Testicular cancer is not typically treated with Prednisone because it is a form of cancer that requires specific treatments such as surgery, chemotherapy, or radiation therapy. Prednisone is not the primary treatment option for testicular cancer. In contrast, Prednisone is commonly used to manage symptoms in conditions like Cushing's disease, lymphomas, and chronic leukemias by reducing inflammation and suppressing immune response. Therefore, choice B is the correct answer as Prednisone is not a standard treatment for testicular cancer.
