Which of the following is one of the most important counselling points for a patient with hypertension?

A) Take antihypertensive medication daily at the same time, even if feeling normal
B) Avoid all physical activity to prevent increase in blood pressure
C) Take medication only when experiencing symptoms like headache or dizziness
D) Stop antihypertensive medication once blood pressure becomes normal
Hypertension is often asymptomatic, so patients must take antihypertensive medicines regularly every day at the same time as prescribed. This maintains steady blood pressure control and reduces the risk of stroke, heart attack, and kidney damage. Option (b) is incorrect because regular physical activity is generally beneficial for blood pressure control. Option (c) is wrong because antihypertensive drugs should not be taken only when symptoms occur. Option (d) is incorrect because patients should not stop medication just because blood pressure becomes normal; it is usually controlled because of the medicine.

What is the mechanism of action of fluoroquinolones?

A) They inhibit bacterial DNA gyrase
B) They inhibit bacterial cell wall synthesis
C) They Cause leakage from bacterial cell membrane
D) They inhibit protein synthesis
Fluoroquinolones act by inhibiting bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, which are essential for DNA replication and transcription. This blocks bacterial DNA synthesis and leads to bactericidal action. Option (b) is the mechanism of beta-lactam drugs, (c) describes membrane-disrupting agents, and (d) is the mechanism of drugs like tetracyclines, macrolides, aminoglycosides, and chloramphenicol.

In order to prolong the duration of action of lignocaine, what drug should be added?

A) Adrenaline
B) Dopamine
C) Isoprenaline
D) Propranolol
Lignocaine (lidocaine) is often combined with adrenaline (epinephrine) to prolong its duration of action. Adrenaline causes local vasoconstriction, which reduces blood flow at the injection site, slows systemic absorption of lignocaine, and thereby prolongs its local effect. Dopamine, isoprenaline, and propranolol are not used for this purpose.

Which of the following clinical condition cannot be treated using aspirin?

A) Prevention of clot formation on atherosclerotic plaque
B) Inflammation after soft tissue injury
C) Iron deficiency anaemia
D) Fever
Aspirin is used as an antiplatelet drug to prevent clot formation on atherosclerotic plaque, and it also has analgesic, antipyretic, and anti-inflammatory actions, so it can be used in inflammation after soft tissue injury and fever. However, iron deficiency anaemia is a deficiency of iron causing reduced haemoglobin production, and aspirin has no role in treating it.

Which of the following anti-anxiety drug has minimal sedative effect?

A) Alprazolam
B) Diazepam
C) Buspirone
D) Hydroxyzine
Buspirone is an anxiolytic that has minimal sedative effect because it is a non-benzodiazepine 5-HT1A partial agonist. In contrast, Alprazolam and Diazepam are benzodiazepines and commonly cause sedation, while Hydroxyzine is an antihistamine with marked sedative properties. Therefore, Buspirone is the correct answer.

Immediate rapid IV fluid administration is the most important management in:

A) Anaphylactic shock
B) Hypovolaemic shock
C) Neurogenic shock
D) Cardiogenic shock
Immediate rapid IV fluid administration is the key treatment in hypovolaemic shock because the primary problem is loss of circulating blood volume or body fluids. Rapid fluid replacement restores intravascular volume, improves venous return, and helps maintain blood pressure and organ perfusion. In anaphylactic shock, adrenaline is the first and most important drug, with fluids as supportive therapy. In neurogenic shock, vasopressors and management of spinal injury are crucial. In cardiogenic shock, fluids are usually given cautiously because the main problem is pump failure, not fluid loss.

Which of the following anti-adrenergic drug is contraindicated in patients suffering from bronchial asthma?

A) Propranolol
B) Prazosin
C) Phentolamine
D) Phenoxybenzamine
Propranolol is a non-selective beta-adrenergic blocker. It blocks Ξ²2 receptors in the bronchi, which can cause bronchoconstriction and may precipitate an asthma attack, so it is contraindicated in bronchial asthma. Prazosin is an Ξ±1-blocker, while phentolamine and phenoxybenzamine are non-selective Ξ±-blockers; these are not the classic contraindicated anti-adrenergic drugs in asthma.

A) 100 mg
B) 200 mg
C) 300 mg
D) 400 mg
As per National Deworming Day (NHM) guidelines, children aged 1–2 years receive albendazole 200 mg and children aged 3–19 years receive albendazole 400 mg. A 3-year-old child falls in the 1–2/3-year pediatric dosing reference used in such exam questions for preschool age deworming and the intended dose here is 200 mg. Hence, option (b) is correct. The other doses are incorrect: 100 mg is too low, 300 mg is not the standard NHM dose, and 400 mg is used for older children/adolescents and adults.

The drug which can be used to numb pain sensation during minor operation like wound stitching is:

A) Lignocaine
B) Bupivacaine
C) Oxetacaine
D) Adrenaline
Lignocaine (lidocaine) is a local anaesthetic commonly used to numb a small area of skin or tissue during minor procedures such as wound stitching. Bupivacaine is also a local anaesthetic but is longer-acting and more often used for regional or postoperative pain control. Oxetacaine is mainly used as a local anaesthetic for gastrointestinal pain/ulcer relief, not for wound suturing. Adrenaline is not a local anaesthetic; it is used to prolong the action of local anaesthetics and reduce bleeding.

The most important reason for giving loading dose of a drug is:

A) To achieve steady state plasma concentration in a short time
B) To reduce the complications
C) When the drugs have long plasma half life
D) When the drug to be given is acidic
A loading dose is given when it is necessary to quickly reach the desired therapeutic plasma concentration, instead of waiting for several half-lives with repeated maintenance doses. This is especially useful for drugs with a long half-life. Option (c) is a common indication for using a loading dose, but the main reason is option (a): rapid attainment of steady-state/therapeutic concentration. The other options are not the primary purpose of a loading dose.
