Tick the drug used for amoebiasis treatment:

Correct Answer: B

Rationale: The correct answer is B: Iodoquinol. Iodoquinol is used for amoebiasis treatment due to its effectiveness against the parasite Entamoeba histolytica. It works by disrupting the energy metabolism of the parasite. Nitrofurantoin is an antibiotic primarily used for urinary tract infections. Pyrazinamide is used for tuberculosis treatment. Mefloquine is primarily used for malaria prophylaxis and treatment. Therefore, B is the correct choice for amoebiasis treatment.

Correct Answer: B

Rationale: The correct answer is B: Erythromycin-induced increase in digoxin oral bioavailability. Erythromycin inhibits the metabolism of digoxin, leading to increased serum levels and potential toxicity. This explains the patient's symptoms. A: Hydrochlorothiazide-induced hypokalemia may cause weakness, but not specific symptoms related to digoxin toxicity. C: Hydrochlorothiazide-induced hypocalcemia does not directly impact digoxin levels or cause digoxin toxicity symptoms. D: Captopril-induced decrease in digoxin clearance may increase digoxin levels, but not through oral bioavailability like erythromycin.

Correct Answer: A

Rationale: The correct answer is A: Prole P. The diuretic drug would lead to increased urine volume and electrolyte excretion, resulting in a profile consistent with Prole P, which typically shows decreased urine osmolality, increased urine volume, and increased electrolyte excretion. Choice B, Prole Q, typically shows decreased urine volume and electrolyte excretion, which would not be consistent with diuretic use. Choice C, Prole R, typically shows increased osmolality and decreased volume, which is not in line with diuretic effects. Choice D, Prole S, typically shows normal urine electrolyte values, which would not reflect the impact of a diuretic drug.

Correct Answer: A

Rationale: The correct answer is A) Alteplase. Alteplase is a thrombolytic drug that is used to prevent embolism in the lung and during myocardial infarction by breaking down blood clots that can cause these conditions. Option B) Human growth hormone is not used for preventing embolism or treating myocardial infarction. It is primarily used for promoting growth in children who have growth hormone deficiency. Option C) Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a type of medication used to stimulate the bone marrow to produce more white blood cells. It is not indicated for the prevention of embolism or heart attacks. Option D) EPOGEN (EPO) is a medication that stimulates the production of red blood cells and is commonly used to treat anemia. It is not used for preventing embolism in the lung or during myocardial infarction. Educational Context: Understanding the correct medication for specific conditions is crucial in healthcare. Alteplase is a lifesaving medication used in emergency situations like heart attacks and pulmonary embolisms where prompt intervention is required to dissolve blood clots. Healthcare professionals need to be well-versed in the appropriate use of medications to ensure patient safety and optimal outcomes.

Correct Answer: D

Rationale: Enhanced automaticity in cardiac cells may occur due to a variety of factors, as seen in the options provided in this quiz question. A) ß-adrenergic stimulation: This is a correct option because ß-adrenergic stimulation can increase the automaticity of cardiac cells by activating beta-adrenergic receptors, leading to an increase in heart rate and contractility. B) Hypokalemia: Hypokalemia, or low levels of potassium in the blood, can also enhance automaticity in cardiac cells. Low potassium levels can disrupt the normal electrical activity of the heart, leading to abnormal rhythms and increased automaticity. C) Mechanical stretch of cardiac muscles: Mechanical stretch of cardiac muscles can also lead to enhanced automaticity by altering the conduction pathways within the heart and increasing the likelihood of abnormal electrical impulses. D) All of the above: The correct answer is D, "All of the above," because each of the factors mentioned (ß-adrenergic stimulation, hypokalemia, and mechanical stretch of cardiac muscles) can independently contribute to enhanced automaticity in cardiac cells. Educational context: Understanding the factors that can influence the automaticity of cardiac cells is crucial for healthcare professionals, especially those working in cardiology and critical care settings. By recognizing these factors, healthcare providers can better interpret ECG findings, manage arrhythmias, and provide appropriate treatment to patients with cardiovascular conditions.
