The nurse is preparing to administer tolvaptan to a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory test results should the nurse review before administering the medication?
Correct answer
B
Rationale
Tolvaptan can cause liver injury, so ALT and AST (liver function tests) should be reviewed before administration. Hemoglobin/WBC, troponin/myoglobin, and glucose/HbA1c are not primary concerns.
