EVOLVE MED SURG HESI QUESTIONS WITH CORRECT ANSWERS

EVOLVE MED SURG HESI QUESTIONS WITH CORRECT ANSWERS The nurse is assessing a client's laboratory values following administration of chemotherapy. Which lab value leads the nurse to suspect that the client is experiencing tumor lysis syndrome (TLS)? A) Serum PTT of 10 seconds. B) Serum calcium of 5 mg/dl. C) Oxygen saturation of 90%. D) Hemoglobin of 10 g/dl. - Answer-B) Serum calcium of 5 mg/dl. TLS results in hyperkalemia, hypocalcemia, hyperuricemia, and hyperphosphatemia. A serum calcium level of 5 (B), which is low, is an indicator of possible tumor lysis syndrome. (A, C, and D) are not particularly related to TLS. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, "The client will verbalize symptoms of pacemaker failure." Which symptoms are most important to teach the client? A) Facial flushing. B) Fever. C) Pounding headache. D) Feelings of dizziness. - Answer-D) Feelings of dizziness. Feelings of dizziness may occur as the result of a decreased heart rate, leading to decreased cardiac output (D). (A and C) will not occur as the result of pacemaker failure.

The nurse anticipates which change in prescription for the client? A) The dosage of the diuretic will be decreased. B) The diuretic will be discontinued. C) A potassium supplement will be prescribed. D) The dosage of the diuretic will be increased. - Answer-C) A potassium supplement will be prescribed. This client's potassium level is too low (normal is 3.5 to 5). Taking a thiazide diuretic often results in a loss of potassium, so a potassium supplement needs to be prescribed to restore a normal serum potassium level (C). (A, B, and D) are not recommended actions for restoring a normal serum potassium level.
