Erythrocyte Indices
Bone Marrow Biopsy
Radiologic Studies
The Correct Answer is A
A. Schilling test. The symptoms described are suggestive of pernicious anemia, which is typically diagnosed through a Schilling test to assess vitamin B12 absorption.
B. Erythrocyte Indices. Erythrocyte indices are used to evaluate various aspects of red blood cell characteristics and are not specific to diagnosing pernicious anemia.
C. Bone Marrow Biopsy. While bone marrow biopsy may be used to diagnose certain types of anemia, it is not the primary diagnostic test for pernicious anemia.
D. Radiologic Studies. Radiologic studies are not typically used in the diagnosis of pernicious anemia.

Correct Answer is C
Explanation
A. Presence of Bence-Jones protein in the urine is indicative of multiple myeloma, but hypercalcemia is a more urgent issue to address.
B. Severe back pain is common in multiple myeloma due to bone involvement, but it is not as immediately life-threatening as hypercalcemia.
C. Elevated serum calcium levels (hypercalcemia) are a common complication of multiple myeloma and can lead to various complications, including kidney damage, altered mental status, and cardiac arrhythmias. Therefore, it is crucial to report significantly elevated serum calcium levels promptly to the health care provider for appropriate management.
D. Patient reports no stool for 5 days may indicate constipation, which is important to address but is not as urgent as hypercalcemia in the context of multiple myeloma.
Correct Answer is A
Explanation
A. "You will need to empty your bladder just before the exam.": Emptying the bladder before a pelvic examination allows for better visualization and manipulation of the pelvic organs.
B. "You should douche the evening prior to the examination.": Douching is not recommended before a Pap test as it can disrupt the natural flora of the vagina and may interfere with test results.
C. "You will be required to sign an informed consent prior to the exam.": Informed consent may be required for certain procedures but is not typically needed for a Pap test.
D. "You will be given light sedation before the examination starts.": Sedation is not typically used for a Pap test, which is a simple procedure that does not usually cause significant discomfort.
