A portable device to save your large files

Correct Answer: A

Rationale: The correct answer is A: Thumb drive. A thumb drive, also known as a USB flash drive, is a portable device that can store large files. It is convenient, small in size, and lightweight, making it easy to carry around. Thumb drives have larger storage capacities compared to diskettes, making them more suitable for saving large files. They are also compatible with most devices and offer faster data transfer speeds. Summary: - B: Diskette is an outdated storage device with limited capacity and slower data transfer speeds compared to a thumb drive. - C: No information given. - D: No information given.

Correct Answer: A

Rationale: The correct answer is A: False low reading. When using a normal size cuff on an obese patient, it can result in falsely low blood pressure readings due to the cuff not fitting properly around the larger arm. This can lead to inaccurate readings and potentially missing hypertension diagnosis or improper management. Choice B (False high reading) is incorrect because a normal size cuff would not typically cause a falsely high reading in an obese patient. Choices C and D are left blank as they are not relevant to the question.

Correct Answer: B

Rationale: The correct answer is B: Falls. Falls are the most common accident in hospitals due to various factors such as patient mobility issues, medication side effects, and environmental hazards. This is supported by data showing a high incidence of falls in healthcare settings. Burns (choice A) are less common in hospitals compared to falls. Choices C and D are likely left blank as they are irrelevant to the context of hospital accidents. In summary, falls are the most common hospital accident due to their frequency and preventable nature.

Correct Answer: A

Rationale: The correct answer is A because hand washing before checking blood pressure is essential to prevent the spread of infection. This step helps maintain good hygiene and reduces the risk of transmitting harmful bacteria to the patient. By washing hands first, the healthcare provider demonstrates professionalism and adherence to infection control protocols. Additionally, clean hands are crucial for accurate blood pressure readings. Choices B, C, and D are incorrect because explaining to the patient, while important, should come after ensuring proper hand hygiene. Choice C and D are incomplete options and do not provide any relevant information related to the proper procedure for checking blood pressure.

Correct Answer: A

Rationale: The correct answer is A because coffee contains caffeine, a stimulant that can increase pulse rate by stimulating the release of adrenaline. Adrenaline causes the heart to beat faster, leading to an increase in pulse rate. Choice B is incorrect as caffeine is known to have a stimulating effect on the cardiovascular system. Choices C and D are incomplete, so they do not provide any relevant information to determine their correctness. In conclusion, the correct answer A is supported by the physiological effects of caffeine on the body, leading to an increase in pulse rate.
