Which of the following is an adverse effect of frusemide?

Correct Answer: B

Rationale: Frusemide (furosemide), a loop diuretic, affects fluid and electrolyte balance, leading to specific side effects. 'Hypotension,' is correct because it causes rapid fluid loss, reducing blood volume and pressure, as per clinical pharmacology (e.g., Brunton's Goodman & Gilman). 'Hyperchloraemia,' is false; frusemide causes hypochloremia via chloride loss. 'Hypermagnesia,' is incorrect; it leads to hypomagnesemia. 'Tearing,' is unrelated to diuretic effects. Hypotension's prevalence as a documented adverse effect, especially in overdose or dehydration, distinguishes B as the accurate answer, reflecting frusemide's mechanism.

Correct Answer: B

Rationale: Delimitation defines the study's boundaries, set by the researcher. 'Scope of the study,' is correct because it outlines what's included (e.g., population, time), per research texts (e.g., Creswell). 'Limitation of the study,' addresses constraints beyond control. 'Relevance of the study,' justifies importance. 'Objective of the study,' states goals. Scope's role in setting intentional limits—e.g., nurses in urban hospitals'—distinguishes B as the accurate answer.

Correct Answer: B

Rationale: The greater omentum, a peritoneal fold, lies anterior to the small intestine, draping over it. 'Anterior,' is correct, per anatomical positioning (e.g., Netter's Atlas). 'Posterior,' is incorrect; it's behind the stomach, not intestine. 'Superficial,' is vague but implies skin-level. 'Deep,' suggests below, not above. Anterior's directional accuracy makes B the precise answer.

Correct Answer: D

Rationale: Arteries withstand pulse pressure via elasticity. 'An elastic tunica media,' is correct, allowing stretch and recoil (e.g., aorta), per anatomy (e.g., Ross). 'A thick tunica interna,' is less relevant. 'A rigid tunica media,' resists stretch. 'A flexible endothelium,' is minor. Elasticity in the media makes D the accurate answer.

Correct Answer: A

Rationale: The thyroid gland's functional unit is the follicle, where thyroid hormones are synthesized and stored. 'Follicle,' is correct, per histology texts like Ross and Pawlina, consisting of follicular cells around colloid. 'Acini,' are exocrine gland units (e.g., pancreas). 'Islets of Langerhans,' are pancreatic endocrine units. 'Alveoli,' are lung units. Follicles' role in T3/T4 production distinguishes A as the accurate answer, specific to thyroid anatomy.
