Appeared in: SGPGI Nursing Officer-2023

Explanation

This pair is incorrect because the pancreas and the hormone inhibin belong to completely separate physiological systems.
The pancreas is a key organ in both the digestive system (exocrine function) and the endocrine system, where it produces insulin and glucagon to regulate blood glucose levels.
Inhibin is a hormone primarily produced by the gonads (Sertoli cells in males and granulosa cells in females) to regulate the secretion of Follicle-Stimulating Hormone (FSH) from the pituitary gland, playing a role in the reproductive cycle.

Option A: This pair is incorrect. Human Chorionic Gonadotropin (HCG) is the 'pregnancy hormone' and is produced by the syncytiotrophoblast cells of the placenta, not the ovary.
Option C: This pair is factually correct. Adipose (fat) tissue produces the hormone leptin. Therefore, it is an incorrect answer for a question that asks to identify an incorrect pair.
Option D: This pair is incorrect. Secretin is not a component of gastric juice. It is a hormone secreted by the S-cells of the duodenum (small intestine) in response to the acidic chyme (partially digested food and gastric juice) arriving from the stomach.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Sources of major hormones in the human body as background academic context rather than a clinical decision trigger.
Accurate knowledge of hormone origins is fundamental for diagnosing and managing endocrine disorders.
For example, measuring HCG levels is a standard method for confirming pregnancy. Elevated or abnormal levels can indicate ectopic pregnancy or other complications.
Measuring inhibin levels can be part of a fertility workup to assess ovarian reserve in women or testicular function in men.

How to Approach the Question

First, identify that the question asks you to find the INCORRECT pair. This means you are looking for a factually wrong statement.
Systematically evaluate each option by recalling the primary hormones produced by each gland or tissue.
Analyze Option A: Ovary produces estrogen/progesterone; HCG is from the placenta. This is incorrect.
Analyze Option B: Pancreas produces insulin/glucagon; Inhibin is from the gonads. This is incorrect.
Analyze Option C: Adipose tissue produces leptin. This is correct.
Analyze Option D: Gastric juice contains acid/enzymes; Secretin is a hormone from the duodenum. This is incorrect.

Concept Tested & Keywords

Concept Tested: Sources of major hormones in the human body.
Stem keywords: incorrect pair, Ovary, HCG, Pancreas, Inhibin, Adipose tissue, Leptin, Gastric juice
Lead-in keywords: Identify, incorrect
Negative lead-in flag: INCORRECT changes the reasoning strategy; look for the exception or incorrect statement rather than the true statement.
