Medication Adherence Strategies Indian Medical PG Practice Questions and MCQs
Question 1: Many of our bad habits of day to day life can be removed by:
- A. Using biofeedback techniques
- B. Applying learned behaviors to new contexts
- C. Reinforcing good behaviors with rewards
- D. Associating bad habits with unpleasant outcomes (Correct Answer)
Explanation: ***Associating bad habits with unpleasant outcomes*** - This technique, known as **aversion therapy**, directly links the undesirable habit with negative consequences, making the habit less appealing to the individual. - By creating an unpleasant association, the brain starts to avoid the habit to prevent the expected negative outcome. *Using biofeedback techniques* - **Biofeedback** involves monitoring physiological responses to gain conscious control over involuntary bodily functions, such as heart rate or muscle tension. - While helpful for stress reduction or managing certain physical conditions, it is not a primary method for directly removing behavioral bad habits. *Applying learned behaviors to new contexts* - This describes **generalization**, where skills learned in one situation are transferred to another. - While important for skill development, it does not directly address the mechanism for *removing* bad habits; rather, it extends good habits or coping strategies. *Reinforcing good behaviors with rewards* - **Positive reinforcement** strengthens desired behaviors by providing rewards, encouraging their repetition. - While effective for building good habits, it doesn't directly dismantle existing *bad* habits, though it can indirectly replace them over time.
Question 2: A depot contraceptive, DMPA, is to be given every:
- A. 1 month
- B. 2 months
- C. 3 months (Correct Answer)
- D. 6 months
Explanation: ***3 months*** - **Depot medroxyprogesterone acetate (DMPA)**, commonly known as **Depo-Provera**, is a highly effective injectable contraceptive. - It works by preventing ovulation and thickening cervical mucus and is administered as an **intramuscular injection** every **12 to 13 weeks** (approximately 3 months). *1 month* - While some **combined oral contraceptives** and **vaginal rings** are used on a monthly cycle, DMPA is not [1]. - Administering DMPA monthly would result in unnecessarily high hormone levels and potential side effects. *2 months* - Administering DMPA every two months is not the standard dosing regimen for this contraceptive. - The efficacy and duration of action of DMPA are well-established for a 3-month interval. *6 months* - The contraceptive effect of DMPA typically lasts for about 3 months; therefore, waiting 6 months between injections would leave the user unprotected for a significant period. - Other long-acting reversible contraceptives (LARCs) like some **subdermal implants** or **intrauterine devices (IUDs)** can provide protection for longer periods, but not DMPA.
Question 3: Why is a regimen of four drugs recommended for a TB patient on the first visit?
- A. To prevent emergence of drug-resistant strains (Correct Answer)
- B. To reduce bacterial load effectively
- C. To minimize treatment duration
- D. None of the options
Explanation: ***To prevent emergence of drug-resistant strains*** - Using a **four-drug regimen** at the initial stage significantly reduces the likelihood of **Mycobacterium tuberculosis** developing resistance to any single drug. - This strategy ensures that even if a small number of bacteria are naturally resistant to one drug, the other drugs will still be effective in killing them, preventing the proliferation of **resistant strains**. *To minimize treatment duration* - While a multi-drug regimen is effective, its primary goal is not to minimize treatment duration but rather to ensure **eradication of the infection** and prevent resistance. - Treatment duration is determined by the need to kill both actively multiplying and dormant bacteria, which typically takes several months even with multiple drugs. *To reduce bacterial load effectively* - Reducing bacterial load is certainly a goal of TB treatment, but the use of four drugs is specifically aimed at achieving this while simultaneously preventing **drug resistance**. - A single effective drug could reduce bacterial load, but it would quickly lead to the emergence of resistant bacteria, making the long-term goal of **cure** impossible. *None of the options* - This option is incorrect because the primary reason for a **four-drug regimen** in TB treatment is indeed to prevent the emergence of **drug-resistant strains**.
Question 4: Which of the following statements about the DOTS treatment for tuberculosis is correct?
- A. Case finding 80%, cure rate 85%
- B. Case finding 80%, cure rate 80%
- C. Case finding 70%, cure rate 75%
- D. Case finding 70%, cure rate 85% (Correct Answer)
Explanation: ***Case finding 70%, cure rate 85%*** - The **DOTS strategy** set a global target of detecting at least **70% of new sputum smear-positive TB cases** and curing at least **85% of these cases**. - Achieving these targets was considered crucial for controlling the spread of **tuberculosis** at a population level. *Case finding 80%, cure rate 85%* - While a **cure rate of 85%** is a key target of the DOTS strategy, the **case finding target was not 80%**. - Setting a higher case finding target might be desirable, but the **established goal** for DOTS was slightly lower to be more achievable. *Case finding 80%, cure rate 80%* - Neither the **case finding target nor the cure rate target** for DOTS was 80%. - The **cure rate target** was specifically emphasized as being higher to ensure effective treatment outcomes and prevent drug resistance. *Case finding 70%, cure rate 75%* - While **case finding 70%** aligns with the DOTS target, the **cure rate target was higher than 75%**. - A lower cure rate would indicate less effective treatment management, potentially leading to **treatment failures** and the emergence of **multidrug-resistant TB**.
Question 5: In a village, despite health education for oral cancer, people don't follow instructions even after referral. Despite persuasive reminders, people are still reluctant. This best fits under which model:
- A. Health belief model
- B. Public health model
- C. Social compliance
- D. Trans-theoretical model (Correct Answer)
Explanation: ***Trans-theoretical model*** - This model emphasizes that individuals move through distinct stages (precontemplation, contemplation, preparation, action, maintenance) when adopting a new behavior. The villagers' reluctance to follow instructions, despite education and reminders, suggests they are likely in the **precontemplation** or **contemplation** stages, where they are either unaware of the problem or are not yet ready to take action. - The model accounts for the **difficulty in behavior change** even with external efforts, as readiness to change is internal and stages are progressive. *Health belief model* - This model focuses on an individual's perception of the **threat of a health problem** and the **pros and cons of taking action**. While education might address perceived susceptibility and severity, the model doesn't fully explain why people remain reluctant even after persuasive reminders, suggesting other factors beyond belief are at play. - It primarily explains *why* individuals might *consider* changing their behavior but not necessarily *how* they progress through the actual change process. *Public health model* - The public health model is a broad framework used to understand and address health issues at a population level, often focusing on **prevention, promotion, and interventions**. While addressing oral cancer in a village fits within this model's scope, it doesn't specifically explain the *individual psychological barriers* to behavioral change, like reluctance despite education and reminders. - This model is more about **strategies and policies** for population health rather than individual behavior change. *Social compliance* - Social compliance refers to individuals conforming to rules or requests from authority figures or social norms. The scenario explicitly states that despite "persuasive reminders," people are "reluctant," indicating a **lack of compliance** rather than an explanation for the behavior itself. - This term describes the *outcome* of behavior in a social context, not the *underlying psychological process* of behavior change over time.
Question 6: All of the following are done to remove Confounding except:
- A. Randomization
- B. Random Selection
- C. Matching
- D. Blinding (Correct Answer)
Explanation: ***Blinding*** - **Blinding** is a technique used to minimize **bias** (e.g., observer bias, participant bias) by preventing study participants, researchers, or data analysts from knowing treatment assignments. It does **not address confounding variables**. - Blinding ensures that knowledge of the intervention does not influence the outcomes or their assessment, thereby controlling **information bias** and **performance bias**. *Randomization* - **Randomization** is a key method in experimental studies to control for **confounding variables** by distributing them equally among study groups. - It ensures that each participant has an **equal chance** of being assigned to any study group, thus minimizing systematic differences between groups at baseline. *Random Selection* - **Random selection** (or random sampling) is used primarily to create a sample that is **representative** of the larger population, thereby improving **external validity** and **generalizability**. - While it reduces **selection bias**, random selection is **not a standard method for controlling confounding**. Some sources suggest it may help balance unknown confounders compared to convenience sampling, but it is not classified among the primary confounding control methods (randomization, restriction, matching, stratification, multivariable analysis). - In this question context, if we consider standard epidemiological methods, random selection's role in confounding control is indirect at best. *Matching* - **Matching** is a technique used in observational studies to control for known **confounding variables** by selecting controls who are similar to cases with respect to these confounders. - For example, if age and sex are confounders, controls are matched to cases based on these characteristics to ensure comparability and reduce confounding.
Question 7: Therapeutic drug monitoring is done for:
- A. Aspirin
- B. Heparin
- C. Phenytoin (Correct Answer)
- D. Metformin
Explanation: ***Phenytoin*** - **Phenytoin** has a **narrow therapeutic window**, meaning the difference between an effective and a toxic dose is small, necessitating close monitoring. - Its **variable absorption** and **nonlinear pharmacokinetics** (saturable metabolism) make individual dosing adjustments critical to maintain therapeutic levels and avoid toxicity. *Aspirin* - **Aspirin** is generally not monitored via plasma levels for its analgesic or antiplatelet effects, as its therapeutic effects are often observed at doses where plasma monitoring is not practical or necessary. - Its primary therapeutic use as an **antiplatelet agent** is evaluated by clinical outcomes rather than drug concentration. *Heparin* - **Heparin** is monitored using coagulation tests like **aPTT (activated partial thromboplastin time)** or anti-Xa levels to assess its anticoagulant effect, not direct drug concentration. - Therapeutic drug monitoring for heparin focuses on its **pharmacodynamic effects** on the clotting cascade rather than its absolute plasma concentration. *Metformin* - **Metformin** has a relatively **wide therapeutic index** and its efficacy is primarily measured by reductions in blood glucose and HbA1c, not by plasma drug concentrations. - It is excreted largely unchanged by the kidneys, and dose adjustments are typically made based on **renal function** and glycemic control.
Question 8: After a thorough study of socio-demographic characteristics of a population in Dhok Ratta, a relevant method of health education against smoking was employed to this population. Upon assessing the population habits even after lapse of 2 years, no change in the behaviour of the smokers was noted. What is likely to be missing in this programme to achieve the desired results?
- A. Knowledge of beliefs
- B. Knowledge of cultures
- C. Reinforcement (Correct Answer)
- D. Required devotion
Explanation: ***Reinforcement*** - **Reinforcement** is crucial for sustaining behavior change over time, especially for habits like smoking. Without continued support and reminders, initial educational efforts often fade. - The lack of change after two years, despite an initial "relevant method of health education," suggests that the initial intervention was not adequately reinforced to maintain its impact. *Knowledge of beliefs* - While understanding **beliefs** is vital for tailoring health education messages, the question states that "a relevant method of health education" was employed after "thorough study of socio-demographic characteristics." This implies beliefs were likely considered in the initial program design. - If the initial program was relevant, it means it probably addressed existing beliefs, but the long-term sustainability was lacking. *Knowledge of cultures* - Similar to beliefs, **cultural understanding** is fundamental for designing effective and relevant health education. The phrase "thorough study of socio-demographic characteristics" suggests that cultural aspects would have been assessed during the program's initial planning. - If the program was initially deemed "relevant," it implies cultural factors were likely addressed, but their ongoing influence requires reinforcement. *Required devotion* - **Devotion**, while important for program implementers, refers more to the commitment of the people running the program rather than a specific component of the health education strategy itself that would directly impact sustained behavior change in the population. - This option is broader and less specific to the programmatic elements that ensure lasting health behavior modification compared to reinforcement.
Question 9: mhGAP program includes all of the following disorders except?
- A. Schizophrenia
- B. Depression
- C. Childhood mental disorder
- D. Personality Disorders (Correct Answer)
Explanation: ***Personality Disorders*** - The **mhGAP program** (Mental Health Gap Action Programme) focuses on scaling up services for common, severe mental, neurological, and substance use disorders in low- and middle-income countries. - **Personality disorders** are generally not included in the core conditions addressed by the mhGAP program due to their complex and chronic nature, requiring specialized and long-term management that may be beyond the scope of primary care settings targeted by mhGAP. *Schizophrenia* - **Schizophrenia** is one of the priority conditions addressed by the mhGAP program, recognizing its severity and significant impact on individuals and communities. - The program provides guidelines for the recognition, management, and long-term care of schizophrenia at the primary healthcare level. *Depression* - **Depression** is a core focus of the mhGAP program, given its high prevalence and treatability in primary care settings. - mhGAP provides clear guidelines for the identification, basic management, and follow-up of individuals with depression. *Childhood mental disorder* - **Childhood mental disorders**, such as conduct disorder, attention-deficit/hyperactivity disorder (ADHD), and developmental disabilities, are also included as priority conditions within the mhGAP program. - The program aims to improve the detection and basic management of these conditions in children and adolescents, promoting early intervention.
Question 10: Treatment of choice for SIADH is:
- A. Hypotonic Saline
- B. Demeclocycline (Correct Answer)
- C. Lithium carbonate
- D. Vasopressin
Explanation: ***Demeclocycline*** - **Demeclocycline** is a tetracycline antibiotic that acts as an **ADH antagonist**, inhibiting its effect on the renal tubules. [1] - This leads to increased free water excretion and a reduction in **hyponatremia** associated with SIADH, making it a treatment of choice, especially for chronic cases. [1] *Hypotonic Saline* - Administering **hypotonic saline** to a patient with SIADH would further dilute serum sodium levels and worsen the **hyponatremia**, which is the opposite of the desired effect. - SIADH is characterized by **excess free water** retention, and adding more free water would exacerbate the underlying pathology. *Lithium carbonate* - While **lithium** can cause nephrogenic diabetes insipidus (a condition of impaired ADH action), it is not the primary or preferred treatment for SIADH. - Its mechanism of action is different, and **demeclocycline** is more specifically targeted at blocking ADH effects in the kidney. *Vasopressin* - **Vasopressin** (ADH) is the hormone that is already in excess or acting excessively in **SIADH**. - Administering more vasopressin would worsen the condition by increasing water reabsorption and further decreasing serum sodium.
