Which of the following statements is true of hepatitis B (HBV)?

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: 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.

Correct Answer: A

Rationale: The correct answer is A because safety should always be the top priority in healthcare. By finding a coworker to help, the nursing assistant ensures a safe transfer for the resident. This approach follows proper protocols and minimizes the risk of injury to both the resident and the nursing assistant. Summary: B: Moving the resident anyway disregards safety and can lead to harm. C: Refusing to move the resident without seeking assistance may delay necessary care. D: Asking the resident to move himself can compromise safety and is not appropriate for a nursing assistant's role.

Correct Answer: A

Rationale: The correct answer is A: Shaving a resident. When shaving a resident, there is a risk of breaking the skin and exposing both the resident and the nursing assistant to blood or bodily fluids. Gloves are necessary to prevent the spread of infection. For the other choices: B: Combing or brushing hair - Gloves are not necessary as there is no direct contact with bodily fluids. C: Dressing a resident - Gloves are not always required unless there is a wound or open sore that needs dressing. D: Turning a resident - Gloves may be needed if the resident has an open wound, but not always necessary for routine turning.

Correct Answer: C

Rationale: The correct answer is C (Radial and brachial). Radial pulse is taken at the wrist, while brachial pulse is taken at the upper arm where blood pressure is commonly measured. These two pulses are commonly used for taking blood pressure readings due to their accessibility and proximity to major arteries. The apical pulse is located at the apex of the heart, not commonly used for blood pressure measurement. The femoral pulse is found in the groin area and is not typically used for measuring blood pressure in clinical settings.
