Nursing QUESTION #9169

Question 11

The Health Belief Model (HBM) was originally developed to explain:

Nurse–patient communication
Why people seek or avoid health screenings✔️
Hospital infection control practices
Management of nursing education

Correct Answer Logic:

The Health Belief Model (HBM) was developed in the 1950s by U.S. Public Health Service researchers (Hochbaum, Rosenstock, Kegels) to explain why people did or did not participate in tuberculosis screening programmes. The HBM is based on four key constructs:

Perceived susceptibility — belief about risk of getting the condition
Perceived severity — belief about seriousness of the condition
Perceived benefits — belief in effectiveness of action
Perceived barriers — belief about costs/obstacles of action

In community health nursing, HBM guides health education and behaviour change interventions.

Agronomy QUESTION #2078

Question 12

ALS (acetolactate synthase) inhibitor herbicides, which include sulfonylureas, imidazolinones, and triazolopyrimidines, control weeds by:

Disrupting cell membrane integrity causing rapid desiccation
Inhibiting the first enzyme in branched-chain amino acid (valine, leucine, isoleucine) biosynthesis, arresting cell division in meristematic tissue — used at very low doses (grams per hectare) due to high enzyme affinity✔️
Blocking photosystem II electron transport causing photo-oxidative damage
Mimicking auxin hormones at supra-optimal concentrations causing uncontrolled growth and plant death

Correct Answer Logic:

ALS inhibitors block acetolactate synthase, preventing synthesis of branched-chain amino acids. Cell division in apical meristems ceases within days. They are active at extremely low doses (5–75 g a.i./ha for sulfonylureas) because of high target affinity. ALS mutation is the most common mechanism of herbicide resistance worldwide due to the single amino acid substitutions that confer resistance.

In the Accounting and Finance for Tourism & Hospitality course, the 'accounting equation' forms the foundation of all financial statements. Which equation correctly represents this fundamental accounting principle?

Correct Answer Logic:

The Accounting and Finance course (Module 2: Basics of Accounting) identifies the Accounting Equation — Assets = Liabilities + Owner's Equity — as the foundational principle underlying the Balance Sheet (Statement of Financial Position). Every business transaction maintains this equation in balance, forming the basis of double-entry bookkeeping and financial reporting.
