Computer in health is useful for

Correct Answer: A

Rationale: Computers in healthcare primarily enhance efficiency and accuracy in managing patient care. 'Keeping database of treatment,' is correct because electronic health records (EHRs) store treatment histories, diagnoses, and medications, improving care coordination, as seen in systems like Epic or Cerner. 'Assisting patient,' is vague and not a primary computer function; assistance comes via staff using tech. 'Browsing social media,' is unrelated to healthcare utility, serving personal rather than clinical needs. 'Blood donation,' involves logistics but isn't a core computer role in health settings. EHRs' role in storing and retrieving treatment data, backed by healthcare IT studies, underscores A as the most significant and widely implemented use, distinguishing it from the less relevant or indirect options.

Correct Answer: A

Rationale: Essential drug policies (e.g., WHO's Essential Medicines List) prioritize proven, cost-effective drugs for population needs. 'New drugs can be easily tried,' is correct as the exception because such policies restrict drug lists to established options, not experimental ones, ensuring safety and efficacy. 'It is medically, therapeutically, and scientifically sound,' is an advantage, reflecting evidence-based selection. 'It responds to real health needs of the people,' is true, targeting prevalent conditions. 'It makes quality control easier,' is accurate, as fewer drugs simplify regulation. Excluding untested new drugs aligns with the policy's focus on reliability, making A the odd one out, per global health guidelines.

Correct Answer: C

Rationale: Local anesthesia complications can be local or systemic. 'Hypotension,' is correct as a systemic effect, often from overdose or rapid absorption (e.g., lidocaine toxicity), per anesthesiology texts (e.g., Morgan & Mikhail). 'Pain,' and 'Edema,' are local, site-specific reactions. 'Nerve damage,' is local, not systemic, unless widespread. Hypotension reflects systemic circulation impact, distinguishing C as the accurate answer, rooted in clinical observations of local anesthetic systemic toxicity (LAST).

Correct Answer: A

Rationale: The statement of the problem defines the issue's scope and severity. 'Statement of the problem,' is correct because it quantifies the problem's extent (e.g., prevalence rates), per research methodology (e.g., Creswell). 'Purpose of study,' outlines intent, not magnitude. 'Significance of the study,' explains importance, not size. 'Relevance of the study,' justifies pertinence, not scale. The problem statement's role in detailing the issue's magnitude—e.g., 30% of nurses face burnout'—makes A the accurate answer.
