A patient is diagnosed with hypertension.
What is the initial recommendation for this patient likely to be?
Angiotensin-converting enzyme (ACE) inhibitor.
Combination diuretic.
Beta-adrenergic blocking agent.
Diet and exercise.
The Correct Answer is D
According to the International Society of Hypertension, lifestyle interventions are recommended for three to six months before medication in patients with grade 1 hypertension (BP < 160/100 mm Hg) and no comorbidities. Diet and exercise can lower BP by reducing weight, sodium intake, alcohol consumption, and stress levels.
Choice A is wrong because angiotensin-converting enzyme (ACE) inhibitors are not the first-line medication for hypertension in the general population. They are preferred in patients with diabetes, chronic kidney disease, or heart failure.
Choice B is wrong because combination diuretics are not the initial recommendation for hypertension. They are used when monotherapy is not sufficient to achieve the target BP or when there is fluid retention.
Choice C is wrong because beta-adrenergic blocking agents are not the first-line medication for hypertension in the general population. They are preferred in patients with ischemic heart disease, heart failure, or arrhythmias.

Correct Answer is B
Explanation
Class IV antidysrhythmics or calcium channel blockers decrease the flow of calcium ions into cardiac and vascular smooth muscle cells, thus decreasing heart rate and contractions.By reducing the calcium influx, they also decrease the slope of phase 0 and 4 and prolong phase 2 of the cardiac action potential.This results in vasodilation, reduced myocardial oxygen demand, and decreased conduction through the AV node.
Choice A is wrong because calcium channel blockers do not increase blood vessel spasm, but rather cause vasodilation.
Choice C is wrong because calcium channel blockers do not decrease refractory period, but rather prolong it by extending phase 2 of the cardiac action potential.
Choice D is wrong because calcium channel blockers do not increase heart rate, but rather decrease it by slowing down the pacemaker activity and AV nodal conduction.
Normal ranges for heart rate are 60 to 100 beats per minute, and for blood pressure are 120/80 mmHg or lower.
Correct Answer is D
Explanation
Thrombolytic agents are a classification of drugs that dissolve blood clots by activating the enzyme plasmin, which breaks down the proteins (fibrins) that form clots. They are used for serious conditions, such as stroke, pulmonary embolism, or heart attack when the blood flow needs to be restored quickly.
Choice A is wrong because salicylates are anti-inflammatory drugs that inhibit the synthesis of prostaglandins, which are involved in inflammation and pain. They also have antiplatelet effects, but they do not dissolve existing clots.
Choice B is wrong because antiplatelets are drugs that prevent platelets from sticking together and forming clots. They are used to prevent clotting in conditions such as coronary artery disease, stroke, or peripheral arterial disease. They do not dissolve existing clots either.
Choice C is wrong because anticoagulants are drugs that prevent clots from forming by interfering with the clotting factors that are normally present in the blood.
They are used to treat or prevent conditions such as deep vein thrombosis, pulmonary embolism, or atrial fibrillation. They do not dissolve existing clots.
Normal ranges for clotting factors vary depending on the laboratory and the method used, but some common values are:
• Prothrombin time (PT): 11 to 13 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
• Fibrinogen: 200 to 400 mg/dL
• D-dimer: less than 0.5 mcg/mL
