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. Healthcare workers are at risk of contracting HBV through exposure to infected blood or body fluids, so getting vaccinated is crucial. Choice A is incorrect as HBV is indeed a serious threat to healthcare workers. Choice C is incorrect as HBV is primarily spread through blood-to-blood contact, not by drinking contaminated water. Choice D is incorrect as HBV can lead to severe complications and even death if left untreated.

Correct Answer: C

Rationale: The correct answer is C. A nursing assistant's responsibility for the resident during discharge ends when the resident is safely seated in the vehicle. This is because the nursing assistant's duty is to ensure the safe transfer of the resident from the facility to the vehicle. Once the resident is seated in the vehicle, the nursing assistant's direct responsibility for the resident's well-being ceases as the transportation process has been successfully completed. Choice A is incorrect because the doctor writing the discharge order does not directly relate to the nursing assistant's responsibility for the resident's discharge process. Choice B is incorrect as the packing of the resident's belongings is not the main focus of the nursing assistant's duty during discharge. Choice D is incorrect because the closing of the vehicle's doors is not the key indicator for the completion of the nursing assistant's responsibilities; ensuring the resident's safe seating in the vehicle is the critical factor.

Correct Answer: A

Rationale: The correct answer is A because it prioritizes resident safety by seeking assistance when unsure. Finding a coworker to help ensures safe transfer of the resident without risking injury. Refusing to move the resident (C) may delay necessary care. Moving the resident alone (B) disregards safety concerns. Asking the resident to move themselves (D) is not appropriate as they may not be capable or it may lead to harm.

Correct Answer: A

Rationale: The correct answer is A: Shaving a resident. Gloves must be worn during shaving to prevent the transmission of infections through cuts or broken skin. Shaving involves contact with blood, which poses a risk of infection. The other choices (B: Combing or brushing hair, C: Dressing a resident, D: Turning a resident) do not involve direct contact with bodily fluids or broken skin, so gloves are not necessary for these procedures. It is essential to maintain proper hygiene practices to ensure the safety and well-being of the residents.

Correct Answer: C

Rationale: The correct answer is C: Radial and brachial. Radial pulse is commonly used for a quick assessment of blood pressure, while brachial pulse is used with a blood pressure cuff for accurate measurement. Radial and apical pulses do not directly relate to blood pressure. Apical and brachial pulses are not typically used together for blood pressure measurement. Brachial and femoral pulses are not commonly used for taking blood pressure in clinical practice.
