This leads to decreased production of red blood cells. Choice B, hypoxia, is a symptom of anemia but not a specific type. Choice C, pernicious anemia, is caused by a lack of intrinsic factor needed for vitamin B12 absorption, not iron. Choice D, pulmonary anemia, is not a recognized form of anemia.

Correct Answer: A

Rationale: The correct answer is A because when a resident with Alzheimer's disease becomes violent, the nursing assistant (NA) should prioritize safety by stepping out of the way to avoid harm and removing triggers that may be causing aggression. Restraining the resident (choice C) can escalate the situation and may lead to physical harm. Yelling at the resident (choice D) can further agitate them and worsen the behavior. It is crucial for the NA to remain calm, assess the situation, and take preventive measures to ensure the safety of both the resident and themselves.

Correct Answer: D

Rationale: The correct answer is D: Flu-like symptoms. In the beginning stages of HIV infection, individuals often experience flu-like symptoms such as fever, fatigue, sore throat, swollen lymph nodes, and muscle aches. This is known as acute HIV infection. These flu-like symptoms typically appear within 2-4 weeks after exposure to the virus. It is important to note that not everyone with HIV will experience these symptoms, and they can be easily mistaken for other viral infections. Incorrect Choices: A: Poor circulation - Poor circulation is not a specific sign of HIV infection. B: Damage to the eyes - Damage to the eyes is not a common early sign of HIV infection. C: Open sores on the penis - While open sores can be a sign of some sexually transmitted infections, they are not specific to HIV infection in the beginning stages.

Rationale: The correct answer is A because providing skin care to the site around the tracheostomy tube helps prevent infection and irritation. Nursing assistants are responsible for maintaining hygiene and skin integrity in residents with tracheostomies. Performing suctioning (B) and removing the tube for cleaning (C) are tasks typically performed by trained healthcare professionals like nurses. Inserting the tube (D) is a specialized procedure that should only be done by trained medical personnel. Therefore, the correct choice is to provide skin care to the site around the tube.

Correct Answer: D

Rationale: The correct answer is D: Two weeks. This is because giving a two-week notice is a standard professional courtesy in the healthcare field. It allows the employer to find a replacement and ensure a smooth transition of care for patients. Choice A is too short and does not provide adequate time for the employer to find a replacement. Choice B is too long and may not be practical for the nursing assistant to wait that long before starting a new job. Choice C is also insufficient as it does not allow for a proper transition period. Overall, option D is the most appropriate choice for changing jobs in the healthcare industry.
