Question 3

Cardiac glycosides like Digoxin are known for their positive inotropic effect, which increases the force of myocardial contraction. This effect primarily involves:

Accepted Answer

B. Inhibiting the Na+/K+-ATPase pump. — Cardiac glycosides inhibit the Na+/K+-ATPase pump in cardiac muscle cells, leading to increased intracellular sodium. This in turn reduces the activity of the Na+/Ca2+ exchanger, resulting in increased intracellular calcium, which enhances myocardial contractility.

Answer

A. Blocking beta-adrenergic receptors.

Answer

C. Increasing cyclic AMP levels.

Answer

D. Dilating peripheral blood vessels.

Question 6

A postpartum mother at 6 weeks requests contraception. She is breastfeeding exclusively and her menses have not returned. Which of the following is the MOST appropriate contraceptive method for her?

Accepted Answer

B. Progestin-only pill (POP) — The progestin-only pill (POP) is the safest contraceptive choice for a breastfeeding mother, as it does not affect milk production or infant growth. COCP is contraindicated due to estrogen's impact on lactation. Cu-IUD and DMPA are effective but may cause irregular bleeding, making POP preferable in the early postpartum period. Lactational amenorrhea alone is unreliable after 6 weeks postpartum.

Answer

A. Combined oral contraceptive pill (COCP)

Answer

C. Copper intrauterine device (Cu-IUD)

Answer

D. Depot medroxyprogesterone acetate (DMPA) injection

Question 9

In a Laminar Airflow Workbench (LAFW), what is the primary function of the High-Efficiency Particulate Air (HEPA) filter?

Accepted Answer

C. To provide a continuous flow of air free from 0.3 micron particles, including bacteria and spores. — The HEPA filter is crucial for achieving an aseptic environment by trapping 99.97% of airborne particles 0.3 micrometers or larger, which effectively removes bacteria and fungal spores. This ensures that the air reaching the critical compounding area is essentially particulate and microbial-free. Large dust particles are typically removed by pre-filters, and negative pressure is characteristic of Biological Safety Cabinets for hazardous drugs, not the primary function of a HEPA filter in an LAFW.

Answer

A. To regulate the temperature inside the workbench.

Answer

B. To remove large dust particles from the incoming air.

Answer

D. To create a negative pressure environment for hazardous drug compounding.

Question 10

A Higher Secondary Assistant (HSA) in Kerala conducts a formative assessment activity where students create a 'Concept Map' of a biology topic. Which statement about its purpose and evaluation is CORRECT?

Accepted Answer

B. It helps the teacher identify misconceptions in students' understanding and guide further instruction — Concept maps reveal how students connect ideas, helping teachers spot errors (e.g., 'photosynthesis releases energy'). Distractor A is wrong because maps assess cognitive structure, not creativity. Summative tools (e.g., grades) use written tests, not map complexity.

Answer

A. Concept maps are used exclusively to evaluate students' artistic creativity

Answer

C. Concept maps are a summative tool to assign grades based on map complexity

Answer

D. It is a standardised assessment to compare students across districts
