Which of the following is not a common effect of Midazolam?
- A. Amnesia
- B. Decreased respiratory function
- C. Anesthetic
- D. Dizziness
Correct Answer: D
Rationale: Step-by-step rationale:
1. Midazolam is a benzodiazepine commonly used as a sedative and anxiolytic.
2. Common effects of Midazolam include amnesia, decreased respiratory function, and anesthetic properties.
3. Dizziness is not a common effect of Midazolam but can be a side effect in some individuals.
4. Therefore, choice D (Dizziness) is not a common effect of Midazolam, making it the correct answer.
Summary:
- A: Amnesia - Common effect of Midazolam
- B: Decreased respiratory function - Common effect of Midazolam
- C: Anesthetic - Common effect of Midazolam
- D: Dizziness - Not a common effect of Midazolam, making it the correct answer.

Which of the following is considered a class IA Sodium Channel blocker?
- A. Mexiletine
- B. Amiodarone
- C. Quinidine
- D. Procainamide
Correct Answer: D
Rationale: The correct answer is D: Procainamide. Procainamide is a class IA antiarrhythmic drug that blocks sodium channels, prolonging the action potential duration. This helps to stabilize the heart's rhythm. Mexiletine (A) is a class IB antiarrhythmic drug that blocks sodium channels with fast recovery kinetics. Amiodarone (B) is a class III antiarrhythmic drug that prolongs repolarization by blocking potassium channels. Quinidine (C) is a class IA antiarrhythmic drug that also blocks sodium channels, but it is not a class IB sodium channel blocker like Procainamide.
A drug ending in the suffix (pril) is considered a ______.
- A. H
- B. ACE inhibitor
- C. Antifungal
- D. Beta agonist
Correct Answer: B
Rationale: The correct answer is B: ACE inhibitor. Drugs ending in the suffix (-pril) typically refer to ACE inhibitors, which are commonly used to treat hypertension and heart failure by inhibiting the angiotensin-converting enzyme. ACE inhibitors do not belong to the categories mentioned in the other choices. Choice A (H) is vague and does not provide any relevant information. Choice C (Antifungal) is incorrect as drugs ending in (-pril) are not typically used to treat fungal infections. Choice D (Beta agonist) is also incorrect as drugs ending in (-pril) do not belong to the class of beta agonists, which are used to treat conditions like asthma and COPD.
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.
Potassium-sparing diuretics primarily affect which part of the kidney?
- A. Proximal convoluted tubule
- B. Loop of Henle
- C. Collecting duct
- D. Distal convoluted tubule
Correct Answer: D
Rationale: The correct answer is D: Distal convoluted tubule. Potassium-sparing diuretics, such as spironolactone, act on the distal convoluted tubule by blocking the aldosterone receptor, which leads to decreased sodium reabsorption and potassium retention. This mechanism helps to promote diuresis while preventing potassium loss. Choices A, B, and C are incorrect because potassium-sparing diuretics do not primarily affect the proximal convoluted tubule, loop of Henle, or collecting duct in the kidney.
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.
