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?

Choice A rationale

While followers demonstrating high critical thinking are valuable, passive contribution may not be as beneficial to a nurse leader’s performance. Active participation is often more beneficial in a healthcare setting, as it allows for the exchange of ideas and collaborative problem-solving.

Choice B rationale

Followers who are dependent and passive when they disagree may not contribute effectively to the team’s performance. Constructive disagreement can lead to better decision-making and innovation. Therefore, passive disagreement may not be the most beneficial trait for a nurse leader.

Choice C rationale

Followers who are active contributors and participate in developing and analyzing ideas are highly beneficial to a nurse leader’s performance. Active participation fosters a collaborative environment, encourages the exchange of ideas, and leads to innovative solutions. This type of follower can significantly enhance the performance of a nurse leader and the overall team.

Choice D rationale

While participation in developing and analyzing ideas is important, not being an active contributor can limit the effectiveness of this participation. Active contribution is key to fostering a collaborative and innovative environment.

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.
