Questions on Perioperative Care Questions
Question 1 of 5
The susceptibility of an individual to infection DOES NOT depend on
Correct Answer: B
Rationale: Susceptibility to infection hinges on factors that directly affect the body's ability to resist pathogens. 'Racial status,' is correct as the factor that does not typically influence susceptibility, as race is a social construct with no direct biological link to immune response, per modern medical consensus (e.g., WHO). 'Immune status,' is a key determinant, as a weakened immune system (e.g., HIV) increases infection risk. 'Nutritional status,' matters, as malnutrition impairs immune function (e.g., vitamin deficiencies). 'Metabolic disorder,' like diabetes, heightens susceptibility by disrupting immune responses. Unlike these physiological factors, racial status lacks evidence as a direct causal factor in infection risk, though socioeconomic disparities tied to race might indirectly affect health. Its exclusion from clinical determinants of susceptibility makes B the correct answer.
Question 2 of 5
Which of these routes of drug administration has a demerit of patient being tethered to 'lines and bottles'?
Correct Answer: A
Rationale: The demerit of being tethered to lines and bottles' implies restricted mobility due to continuous delivery equipment. 'Intravenous,' is correct because IV administration often requires catheters and drip bags, limiting movement, as seen in hospital settings (e.g., IV fluids). 'Subcutaneous,' involves small injections or pumps, less restrictive. 'Intramuscular,' is a single shot, not continuous. 'Enteral,' is oral or tube feeding, not involving lines' like IVs. IV's reliance on infusion setups—common in prolonged treatments—makes A the precise answer, reflecting its practical drawback in patient care.
Question 3 of 5
According to the ASA physical status classification system, patients with severe systemic disease that is a constant threat to life are categorized as
Correct Answer: D
Rationale: The ASA classification assesses patient risk before anesthesia. 'ASA PS 4,' is correct for patients with severe systemic disease posing a constant life threat (e.g., unstable angina), per ASA guidelines. 'ASA PS 3,' is severe disease without immediate danger (e.g., stable diabetes). 'ASA PS 2,' is mild systemic disease (e.g., controlled hypertension). 'ASA PS 5,' is moribund patients unlikely to survive 24 hours. ASA PS 4's focus on life-threatening conditions matches the description, making D the precise answer.
Question 4 of 5
Significance of the study in a research work briefly states all the following except
Correct Answer: C
Rationale: The significance of a study explains its value and impact. 'Relationship between two variables,' is correct as the exception because it's part of hypotheses or findings, not significance, per research guides (e.g., Creswell). 'The overall impact...,' and 'Potential benefits...,' highlight societal and individual value. 'Possible usefulness and contribution,' addresses practical implications. Significance focuses on why the study matters, not specific variable links, making C the odd one out, aligned with research structure.
Question 5 of 5
Reliability of the study is determined through
Correct Answer: B
Rationale: Reliability, consistency of measurement, is tested via a pilot study. 'Pilot study,' is correct because it assesses tool reliability (e.g., test-retest), per research methods (e.g., Cronbach). 'Carefully designed questionnaire,' aids reliability but doesn't test it. 'Hypothesis testing,' evaluates validity, not consistency. 'Data analysis,' interprets results, not reliability. Pilot studies' role in pre-testing reliability distinguishes B as the accurate answer.
