2 Which of the following senses is not used in making observations?

Correct Answer: D

Rationale: The correct answer is D: Taste. Taste is not typically used in making observations because observations rely on external stimuli that can be seen, touched, or smelled. Taste involves consuming food or drink, which is not a common method of observation. Sight (A), touch (B), and smell (C) are commonly used senses in making observations. Each of these senses provides valuable information about the external world, making them essential for observation. Taste, on the other hand, is more subjective and personal, making it less reliable and applicable for objective observations.

Correct Answer: D

Rationale: The correct answer is D: Surgical asepsis. Surgical asepsis refers to the practice of creating and maintaining a sterile environment to eliminate all microorganisms. This is crucial in surgical procedures to prevent infections. Infection prevention (choice A) focuses on strategies to reduce the risk of infections but does not necessarily involve complete elimination of microorganisms. Disinfection (choice B) involves killing or inactivating most disease-causing microorganisms, but it does not guarantee complete elimination. Transmission (choice C) refers to the spread of microorganisms from one person to another, which is different from making an area or object completely free of microorganisms.

Correct Answer: B

Rationale: The correct answer is B: The vaccine for HBV helps prevent the disease. This is true because the hepatitis B vaccine is highly effective in preventing HBV infection. It works by stimulating the immune system to produce antibodies that provide protection against the virus. Healthcare workers are recommended to get vaccinated due to the occupational risk of exposure. Choices A, C, and D are incorrect: A: HBV is a serious threat to healthcare workers due to the potential for occupational exposure to infected blood or bodily fluids. C: HBV is primarily spread through exposure to infected blood or bodily fluids, not through drinking contaminated water. D: HBV can cause severe liver damage, liver cancer, and even death if left untreated.

Correct Answer: D

Rationale: The correct answer is D: Extreme thirst. In shock, the body redirects blood flow away from non-essential organs, leading to decreased blood supply to tissues. This triggers a release of stress hormones, causing increased thirst as the body tries to maintain fluid balance. Flushed skin (A) may indicate fever or heat exposure, not necessarily shock. Decreased pulse and respiration rates (B) are signs of severe shock, not an early indicator. Increased blood pressure (C) is typically not a sign of shock but can occur in certain types of shock.

Correct Answer: C

Rationale: The correct answer is C: When the resident is seated in the vehicle. This is because the nursing assistant's responsibility for the resident during discharge ends when the resident is safely seated in the vehicle to ensure a smooth transition. Choice A is incorrect because the discharge order does not signify the end of the nursing assistant's responsibility. Choice B is incorrect as packing belongings is part of the discharge process but not the endpoint of the assistant's responsibility. Choice D is incorrect as closing the vehicle doors does not indicate that the resident is safely inside and ready for departure.
