Which laboratory tests might be ordered to investigate W.R.'s condition? If the order is appropriate, place an A in the space provided. If inappropriate, mark with an I. Provide rationales for your decisions
1. Complete blood count (CBC)
2. Electroencephalogram (EEG) in the morning
3. Basal metabolic panel (BMP)
4. Prothrombin time (PT) and partial thromboplastin time (PTT)
5. Bilirubin
6. Urinalysis (UA)
7. STAT 12-lead electrocardiogram (ECG) and repeat in the morning
8. Type and crossmatch for 2 units of packed red blood cells (PRBCs)
9. Chest x-ray on admission and in the morning
Answers: 1. A; 2. I; 3. A; 4. A; 5. I; 6. A; 7. A; 8. I; 9. A
The CBC, BMP, PT and PTT, and UA are appropriate admitting laboratory tests for all patients with
BP disorders. The STAT 12-lead ECG is appropriate for this patient because his heart is involved. The
chest x-ray will provide information about pulmonary and cardiac status. The EEG, bilirubin, and type
and crossmatch are not appropriate for this patient.
