Answer 1 is incorrect because the creatinine level, which indicates renal function, is within normal limits (0.7 to 1.4 mg/dL). The BUN is elevated, which could indicate possible fluid volume deficit, and further assessment will be needed. Answer 2 is incorrect because the calcium level is within normal limits (8.6 to 10.2 mg/dL). Answer 3 is correct because the normal prothrombin time is 9.5 to 12 seconds. If anticoagulation is desired, the level is usually 1½ to 2 times the normal. This value puts the client at serious risk for bleeding. Answer 4 is incorrect because the Hgb is within normal limits for both men and women.
