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 D
Explanation
Choice A rationale
Assessing the amniotic fluid is important after rupture of membranes, but it is not the immediate priority. The nurse should first ensure the safety of the mother and baby.
Choice B rationale
Walking the patient to the bathroom is not the immediate priority. After rupture of membranes, the patient should be assisted back to bed to prevent cord prolapse.
Choice C rationale
Calling and informing the healthcare provider is important, but it is not the first action. The nurse should first assist the patient back to bed and initiate fetal monitoring.
Choice D rationale
Assisting the patient back to bed and initiating fetal monitoring is the correct action. After rupture of membranes, the priority is to assess the fetal heart rate for any signs of distress, such as bradycardia, which could indicate cord prolapse.
Correct Answer is B
Explanation
Choice A rationale
Epigastric discomfort is a common symptom of peptic ulcer disease, but it is not typically the symptom that should be prioritized. While discomfort can indicate an active ulcer, it does not necessarily signify a complication.
Choice B rationale
Hematemesis, or vomiting blood, is a serious symptom that could indicate a bleeding ulcer, which is a medical emergency. Therefore, this symptom should be prioritized.
Choice C rationale
Dyspepsia, or indigestion, is a common symptom of peptic ulcer disease. However, it is not typically the symptom that should be prioritized as it does not necessarily indicate a serious complication.
Choice D rationale
Constipation is not typically associated with peptic ulcer disease and therefore should not be prioritized.
