Indirect auscultation

Correct Answer: A

Rationale: The correct answer is A: Using a stethoscope. Indirect auscultation involves listening to sounds within the body using a stethoscope. The stethoscope amplifies internal sounds, making them easier to hear. It allows for better identification and diagnosis of abnormal sounds like heart murmurs or lung crackles. Using your ear alone (choice B) would not provide the same level of clarity and detail as a stethoscope. Choice C and D are blank, so they are automatically incorrect as they do not offer any relevant information. Ultimately, the stethoscope is essential for accurate and precise auscultation in medical practice.

Correct Answer: A

Rationale: The correct answer is A: Infant. Infants typically have higher axilla temperatures compared to adults due to their higher metabolic rate and less efficient temperature regulation. Infants have a higher surface area to body mass ratio, making them more prone to heat loss. This results in higher axilla temperatures as a way to compensate for heat loss. Choice B: Adult is incorrect because adults generally have lower axilla temperatures compared to infants due to their lower metabolic rate and more efficient temperature regulation mechanisms. Choices C and D are incomplete and do not provide any relevant information regarding axilla temperature in relation to age groups.

Correct Answer: B

Rationale: The correct answer is B: Nerves. In the context of an inner ear problem related to hearing, the issue is most likely related to the auditory nerve, which transmits signals from the cochlea to the brain for interpretation. Problems with this nerve can lead to hearing difficulties. Choice A (Conduction) typically refers to issues with sound conduction through the ear canal or middle ear, not the inner ear. Choices C and D are likely irrelevant since they are not specified and do not directly pertain to the inner ear or hearing. Therefore, choice B is the most appropriate because it directly addresses the nerve involvement in hearing function.

Correct Answer: B

Rationale: The correct answer is B: Polo with snap-ons. For old patients, snap-ons are easier to manage than buttons due to arthritis or limited dexterity. Snap-ons are more convenient and reduce the risk of struggling with fastening clothing. Choice A with buttons may be difficult for old patients to handle. Choice C and D are incorrect as they do not offer a feasible alternative for easy dressing for older patients.

Correct Answer: B

Rationale: The correct answer is B: Inside a jar. Stool specimens should be collected inside a clean, dry, leak-proof container such as a jar to prevent contamination and ensure accurate testing. Choice A (1 inch) is too vague and does not specify the proper collection method. Choices C and D are incomplete and do not provide any relevant information on how to collect and store a stool specimen. It is essential to follow proper collection procedures to avoid inaccurate test results.
