Which of the following conditions are not treated with Barbiturates?
- A. Seizures
- B. Hypotension
- C. Insomnia
- D. Anxiety
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.

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 not a side effect of the cholinoreceptor blocker (Atropine)?
- A. Increased pulse
- B. Diarrhea
- C. Constipation
- D. Mydriasis
Correct Answer: B
Rationale: The correct answer is B: Diarrhea. Atropine, a cholinoreceptor blocker, inhibits acetylcholine, causing decreased GI motility leading to constipation. Atropine also increases pulse rate due to reduced vagal tone (A). It causes mydriasis by blocking cholinergic receptors in the eye (D). Diarrhea is not a typical side effect of atropine due to its anticholinergic properties.
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 drugs is associated with extreme photosensitivity as a reaction?
- A. Digitalis
- B. Niacin
- C. Tetracycline
- D. Fluoroquinolones
Correct Answer: C
Rationale: The correct answer is C: Tetracycline. Tetracycline is associated with extreme photosensitivity due to its mechanism of action causing phototoxic reactions when exposed to sunlight. Digitalis (A) is a cardiac medication, niacin (B) is a B vitamin, and fluoroquinolones (D) are antibiotics, none of which are known to cause extreme photosensitivity reactions.
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.
