The anti-sterility fat-soluble vitamin is -

Appeared in: Raj. CHO - 2023

Explanation

Vitamin E is also known as tocopherol or the 'anti-sterility' vitamin.
Its role as a powerful antioxidant helps protect cell membranes from oxidative damage, which is crucial for the health of reproductive tissues.
Deficiency of Vitamin E has been associated with sterility or infertility, particularly in animal studies.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Functions and classic names of fat-soluble vitamins as background academic context rather than a clinical decision trigger.
While severe Vitamin E deficiency causing sterility is not a common concern in humans, its deficiency can occur in conditions of fat malabsorption (e.g., cystic fibrosis, chronic liver disease) and lead to neurological issues like peripheral neuropathy and ataxia.
Nurses should educate patients that taking high-dose Vitamin E supplements can interfere with Vitamin K's function, increasing the risk of bleeding. This is particularly important for patients on anticoagulant medications like warfarin.
What if? If a patient presents with symptoms of fat malabsorption (e.g., steatorrhea, weight loss), the nurse should anticipate potential deficiencies in ALL fat-soluble vitamins (A, D, E, and K), not just one, necessitating broader screening and comprehensive supplementation.

How to Approach the Question

This is a factual recall question testing your knowledge of the specific names and functions of vitamins.
First, identify the key phrase in the question stem: 'anti-sterility vitamin'.
Next, systematically review the options and recall the primary function or classic name associated with each fat-soluble vitamin.
Recall that Vitamin A is for vision (anti-xerophthalmic).
Recall that Vitamin D is for bone health (anti-rachitic).
Recall that Vitamin K is for blood clotting (anti-hemorrhagic).
