What does the term 'external validity' refer to in research?

Correct Answer: B

Rationale: The correct answer is B: The ability to generalize findings to other populations. External validity refers to the extent to which research findings can be generalized beyond the specific sample or setting studied. This is crucial for ensuring that the results are applicable to a broader population. In contrast, option A (accuracy of the measurement tool) addresses internal validity, while option C (consistency of research results) is related to internal reliability. Option D (reliability of the sample size) focuses on the consistency and precision of data collection, which is more about internal reliability rather than external validity. Therefore, the correct choice is B as it directly relates to the concept of external validity in research.

Correct Answer: B

Rationale: The correct answer is B: Wash bitten area with soap and water. This is because cleaning the wound helps reduce the risk of infection. Soap and water can help remove bacteria from the bite, reducing the chance of complications. Going to the hospital is important for serious bites, but immediate cleaning is crucial. Choice A is not specific to the immediate first aid needed. Choices C and D are incomplete and do not provide any relevant information for treating a dog bite.

Correct Answer: B

Rationale: The correct answer is B: Constant fever. A constant fever is characterized by a consistent temperature in the fever range without significant fluctuations. This type of fever does not show variations over time, unlike intermittent fever which fluctuates between febrile and afebrile periods. Choices C and D are likely left blank intentionally as they are not relevant to the question. In summary, option B is correct because it accurately describes a fever that remains in the fever range without variation.

Correct Answer: B

Rationale: The correct answer is B: Small intestines. This is because the small intestines are where the majority of nutrient absorption occurs due to its large surface area and presence of villi and microvilli. These structures increase absorption efficiency. The large intestines primarily absorb water and electrolytes, not nutrients. Choices C and D are not provided, but they are incorrect as nutrient absorption primarily occurs in the small intestines.

Correct Answer: B

Rationale: The correct answer is B: Tepid sponge bath. This is the best choice for a child with fever as it helps in reducing body temperature gradually and safely. Sponge baths are recommended over medications like syrup to avoid potential side effects. Other choices (A, C, D) lack the efficacy and safety of a tepid sponge bath in managing fever in children.
