Which of the following is a flammable liquid?

Correct Answer: C

Rationale: The correct answer is C, nail polish remover, because it contains volatile solvents like acetone, making it highly flammable. Water (A) is not flammable. Sweat (B) is mostly water and salts, not flammable. Urine (D) is also primarily water and waste products, not flammable. Flammable liquids like nail polish remover have low flash points and can easily ignite, making them a fire hazard.

Correct Answer: A

Rationale: The correct answer is A: An alternating pressure mattress. This type of mattress helps reduce pressure on specific areas of the body by alternating pressure points, which can prevent pressure injuries. The other choices, B: A bariatric bed, C: An electric bed, and D: A closed bed, do not directly address the prevention of pressure injuries. Bariatric beds are designed for heavier individuals, electric beds assist with adjusting positions, and closed beds do not offer the necessary pressure relief for someone at risk of pressure injuries. Therefore, A is the most appropriate choice for addressing the specific needs of a resident at risk for pressure injuries.

Correct Answer: B

Rationale: The correct answer is B: Wash from cleanest to dirtiest. This approach helps prevent spreading dirt and bacteria from dirty areas to cleaner ones, reducing the risk of infections. It also maintains hygiene standards and promotes overall cleanliness. Choice A is incorrect as it can lead to cross-contamination. Choice C is not ideal as it may not prioritize effective cleaning. Choice D is incorrect as it disregards the resident's preferences and can be unhygienic.

Correct Answer: A

Rationale: The correct answer is A: Radial pulse. The radial pulse is commonly used for measuring pulse rate because it is easily accessible at the wrist, making it convenient for healthcare professionals. The radial artery is close to the surface, making it easy to detect and count the pulsations accurately. Additionally, the radial pulse is a peripheral pulse that reflects the heart rate, making it a reliable indicator of overall cardiovascular function. Summary of incorrect choices: B: Brachial pulse - Located in the upper arm, not as easily accessible as the radial pulse. C: Carotid pulse - Located in the neck, not commonly used for routine pulse measurements due to its location near vital structures. D: Pedal pulse - Located in the foot, less commonly used than the radial pulse for routine pulse measurements.

Correct Answer: A

Rationale: The correct answer is A: NPO. NPO stands for "nil per os," which means nothing by mouth. This abbreviation is used to indicate that a patient should not have anything to eat or drink orally. It is crucial in situations where oral intake needs to be restricted for medical reasons. Explanation for why the other choices are incorrect: B: NCS - NCS stands for "no concentrated sweets" and relates to dietary restrictions for patients with diabetes. It does not indicate complete restriction from oral intake. C: LCS - LCS stands for "low-calorie sweeteners" and is related to artificial sweeteners. It does not indicate complete restriction from oral intake. D: ADA - ADA stands for American Diabetes Association and is an organization related to diabetes management. It does not indicate any restriction from oral intake.
