A nurse is providing care for a patient who the healthcare provider suspects may have pernicious anemia.
Which diagnostic test should the nurse anticipate the healthcare provider will order?
Sweat test
Haptoglobin
Schilling test
Antinuclear antibodies .
The Correct Answer is C
Choice A rationale
A sweat test is used to diagnose cystic fibrosis, a genetic disorder that affects the lungs and digestive system. It is not used to diagnose pernicious anemia.
Choice B rationale
Haptoglobin is a protein produced by the liver that binds to hemoglobin in the blood to prevent it from being excreted through the kidneys. While it can be used to diagnose conditions that cause the destruction of red blood cells, it is not used to diagnose pernicious anemia.
Choice C rationale
The Schilling test is used to determine whether the body absorbs vitamin B12 normally, which is crucial for the diagnosis of pernicious anemia. Pernicious anemia is a condition where the body is unable to absorb vitamin B12 due to a lack of intrinsic factor, a protein made in the stomach.
Choice D rationale
Antinuclear antibodies (ANAs) are a type of autoantibody that can attack the body’s own tissues. While they can be present in various autoimmune diseases, they are not used to diagnose pernicious anemia.

Correct Answer is A
Explanation
Choice A rationale
The task of recording strict nutritional content is within the scope of practice for an assistive personnel (AP). The AP can keep track of the client’s food and fluid intake and report this information to the nurse. This is important in this case as the client has not been eating and the provider has prescribed a regular tray with finger foods at each meal. The nurse can then use this information to assess the client’s nutritional status and make necessary adjustments to the care plan.
Choice B rationale
Administering medication, such as memantine, is not within the scope of practice for an AP. This task requires knowledge and skills related to pharmacology, assessment, and evaluation that are beyond the training of an AP. Therefore, this task should be performed by a licensed nurse.
Choice C rationale
Performing neurological checks is also not within the scope of practice for an AP. These checks involve assessing the client’s level of consciousness, orientation, and neurological function, which require advanced assessment skills. Therefore, this task should be performed by a licensed nurse.
Choice D rationale
Continuing the bowel training program could potentially be within the scope of practice for an AP, depending on the specific tasks involved. However, in this case, the family member has reported that the client is having more difficulty staying focused, which suggests that the bowel training program may need to be adjusted. This requires nursing judgment and therefore should be performed by a licensed nurse.
Correct Answer is A
Explanation
Choice A rationale
The nurse should indeed consider the AP’s level of experience when making delegation decisions. This is because the level of experience can greatly influence the ability of the AP to perform the delegated tasks effectively and safely. An experienced AP may be more competent and confident in performing certain tasks compared to someone with less experience. Therefore, considering the AP’s level of experience is crucial in ensuring quality care for patients.
Choice B rationale
While it is true that APs can assist in providing client education about basic self-care, it is important to note that the scope of their teaching is limited. They can reinforce teaching done by the nurse but should not be the primary source of education, especially for complex care needs or new diagnoses. Therefore, this statement does not fully reflect effective delegation.
Choice C rationale
This statement is incorrect. Even when care is delegated to an AP, the nurse retains accountability for client outcomes. The nurse remains responsible for ensuring that the delegated tasks are completed correctly and safely. Therefore, this statement does not indicate effective delegation.
Choice D rationale
This statement is also incorrect. APs should not re-delegate tasks to another AP1. The nurse who delegated the task has assessed the competency and capabilities of the specific AP to whom the task was delegated. Re-delegation could lead to tasks being performed by someone who may not have the necessary skills or knowledge, potentially compromising patient safety.
