Sedation,peripheral atropine-like toxicity (e.g. Cycloplegia tachycardia urinary retention and constipation) orthostatic hypotension arrhythmias weight gain and sexual disturbances are possible adverse effects of:

Correct Answer: B

Rationale: The correct answer is B: Amitriptyline. Amitriptyline is a tricyclic antidepressant known for its anticholinergic properties, leading to peripheral atropine-like toxicity such as cycloplegia, tachycardia, urinary retention, and constipation. It can also cause orthostatic hypotension, arrhythmias, weight gain, and sexual disturbances. Explanation: 1. Amitriptyline is a tricyclic antidepressant that exerts anticholinergic effects, leading to peripheral atropine-like toxicity. 2. Anticholinergic effects can cause cycloplegia, tachycardia, urinary retention, and constipation. 3. Additionally, amitriptyline can lead to orthostatic hypotension, arrhythmias, weight gain, and sexual disturbances. Summary of other choices: A: Sertaline - Known for causing fewer anticholinergic side effects compared to tricy

Correct Answer: D

Rationale: Step 1: General anesthesia involves analgesia to block pain signals. Step 2: It causes loss of consciousness by inhibiting sensory and autonomic reflexes. Step 3: It induces amnesia to prevent memory formation during the procedure. Step 4: Therefore, all the elements - analgesia, loss of consciousness, and amnesia - are essential components of general anesthesia, making choice D the correct answer. Other choices are incorrect because they individually do not cover all the necessary aspects of general anesthesia.

Correct Answer: A

Rationale: Step 1: Zileutin is a leukotriene synthesis inhibitor. Step 2: Leukotrienes are inflammatory mediators produced by the body. Step 3: By inhibiting leukotriene production, zileutin reduces inflammation. Step 4: Therefore, the statement "Zileutin prevents the production of leukotrienes" is TRUE. Summary: Choice A is correct because zileutin indeed prevents the production of leukotrienes, leading to reduced inflammation. Choices B, C, and D are incorrect as they do not accurately reflect the mechanism of action of zileutin.

Correct Answer: A

Rationale: The correct answer is A, Filgrastim, as it is a granulocyte colony-stimulating factor used to stimulate the production of neutrophils. Filgrastim is commonly prescribed to increase white blood cell count in patients undergoing chemotherapy. Methotrexate (B) is a chemotherapy drug that does not stimulate granulocyte production. Erythropoietin (C) stimulates red blood cell production, not granulocytes. Doxorubicin (D) is an anthracycline antibiotic used in cancer treatment but does not stimulate granulocyte colony formation. Thus, the correct drug for granulocyte colony-stimulating factor is Filgrastim.

Correct Answer: A

Rationale: Rationale: 1. Flecainide is classified as a Class IC antiarrhythmic drug based on Vaughan Williams classification. 2. Class IC drugs block sodium channels in cardiac tissue, slowing conduction. 3. Flecainide is used to treat ventricular arrhythmias. 4. Sotalol (Class III), Lidocaine (Class IB), and Verapamil (Class IV) belong to different antiarrhythmic classes. Summary: Sotalol is a Class III antiarrhythmic drug that blocks potassium channels. Lidocaine is a Class IB drug that blocks sodium channels. Verapamil is a Class IV drug that blocks calcium channels. These drugs have different mechanisms of action compared to Class IC drugs like Flecainide.
