-
A patient receiving a topiramate prescription for migraine prevention reports experiencing paresthesias (numbness or tingling). What is the most likely reason for this side effect?
सही उत्तर: ग) Neurotransmitter modulation
Option 2, ‘Neurotransmitter modulation,’ is correct. Topiramate's mechanism of action involves modulating neuronal excitability by affecting multiple neurotransmitters, which can manifest as paresthesias as a side effect. Options 1, 3, and 4 do not represent the drug’s primary mechanism or associated effects.

A patient taking digoxin is monitoring for signs of toxicity. Which electrolyte imbalance is most commonly associated with digoxin toxicity?
सही उत्तर: क) Hypokalemia
Option 0, ‘Hypokalemia,’ is correct. Hypokalemia (low potassium) is the most common electrolyte disturbance that increases the risk of digoxin toxicity by potentiating its negative inotropic effects. Options 1, 2, and 3 represent alternative electrolyte imbalances associated with cardiac conditions.

A patient with a history of osteoporosis is prescribed raloxifene. The nurse understands the primary purpose of this medication is to:
सही उत्तर: घ) Inhibit osteoclast activity
Option 3, ‘Inhibit osteoclast activity,’ is correct. Raloxifene is a selective estrogen receptor modulator (SERM) that primarily inhibits osteoclastic bone resorption (breakdown), thereby reducing bone loss. Options 1, 2, and 4 are incorrect as they describe alternative mechanisms of action.

-
A patient requires intravenous administration of vancomycin. The nurse understands that a significant adverse effect associated with this antibiotic is:
सही उत्तर: ख) Nephrotoxicity
Option 1, ‘Nephrotoxicity,’ is correct. Vancomycin is known to be nephrotoxic and can cause kidney damage, particularly at higher doses or with prolonged use. Options 2, 3, and 4 are not typical adverse effects of vancomycin.

A patient is prescribed metoprolol for hypertension. The nurse should advise the patient to report which of the following symptoms?
सही उत्तर: घ) Excessive thirst
Option 3, ‘Dizziness or lightheadedness,’ is correct. Metoprolol, a beta-blocker, can cause dizziness or lightheadedness, particularly when standing up quickly, due to its effect on blood pressure and heart rate regulation. Options 1, 2, and 4 are not commonly associated with metoprolol’s side effects.

-
A patient receiving intravenous heparin for deep vein thrombosis (DVT) reports experiencing bruising at the injection site. What is the most likely explanation for this?
सही उत्तर: ख) Thrombocytopenia
Option 1, ‘Thrombocytopenia,’ is correct. Heparin's mechanism of action involves preventing platelet aggregation; thrombocytopenia (low platelets) can exacerbate this effect, leading to increased bruising at the injection site. Options 2, 3, and 4 represent alternative causes for bruising that are less directly related to heparin’s anticoagulant effects.

-
A patient with newly diagnosed hypertension has been prescribed lisinopril. The nurse should instruct the patient that a common side effect of this medication is:
सही उत्तर: ख) Dry cough
Option 1, ‘Dry cough,’ is correct. Lisinopril belongs to the class of ACE inhibitors, and a dry cough is a frequent adverse effect associated with this drug class due to its inhibition of bradykinin production. Options 2, 3, and 4 are not typical side effects of lisinopril.

-
A patient with heart failure is prescribed furosemide (Lasix). The nurse understands that this medication primarily works by:
सही उत्तर: क) Reducing preload
Option 0, ‘Reducing preload,’ is correct. Furosemide is a loop diuretic that reduces preload (venous return to the heart) by promoting sodium and water excretion, thereby decreasing fluid volume circulating through the vasculature. Options 1, 2, and 3 are incorrect as they relate to different mechanisms of action or effects.

-
A client with a diagnosis of type 2 diabetes is prescribed metformin. Which dietary recommendation should the nurse reinforce for this client?
सही उत्तर: ख) B) Limit intake of foods containing added sugars and refined carbohydrates
Option B is correct. Metformin’s primary mechanism involves improving insulin sensitivity and reducing glucose production, making it essential to limit carbohydrate intake, particularly those high in added sugar and refined carbohydrates. Options A and C are contraindicated; Option D is incorrect as fruit contains beneficial nutrients.

-
A patient with a history of asthma is prescribed montelukast (Singulair) for seasonal allergies. What key instruction should the nurse provide to the patient regarding potential side effects?
सही उत्तर: ख) B) ‘Report any difficulty breathing or wheezing immediately.’
Option B is correct. Montelukast can cause bronchospasm in susceptible individuals, so the patient must be instructed to report any breathing difficulties or wheezing immediately. The other options are incorrect regarding this medication's effects.
