The nurse is reviewing laboratory results for a client taking dantrolene sodium (Dantrium). The nurse should notify the physician if which of the following is noted on the laboratory report sheet?
 
  1. Creatinine level, 0.6 mg/dL
  2. Platelet count, 290,000/mm3
  3. Blood urea nitrogen (BUN) level, 9 mg/dL
  4. Lactic dehydrogenase (LDH) level, 600 units/L

Question 2

The client has just returned from the cardiac catheterization laboratory. The left-sided femoral vessel was used as the access site. The nurse should position the client:
 
  1. In a semi-Fowler's position
  2. With the head of the bed elevated 45 degrees
  3. With the head of the bed elevated no more than 15 degrees
  4. With the foot of the bed elevated as much as tolerated by the client

Answer to Question 1

4

Rationale: Dose-related liver damage is the most serious adverse effect of dantrolene. To reduce the risk of liver damage, liver function tests should be performed prior to treatment and throughout the treatment interval. It is administered in the lowest effective dosage for the shortest time necessary. The LDH level reported in lactic dehydrogenase (LDH) level, 600 units/L is high (normal level is 140 to 280 units/L). The other options indicate normal laboratory results.

Answer to Question 2

3

Rationale: Following cardiac catheterization, the extremity used for catheter insertion is kept straight for 4 to 6 hours. If the femoral artery was used, strict bed rest is necessary for 6 to 12 hours. The client may turn from side to side. The head of the bed is not elevated more than 15 degrees to prevent kinking of the blood vessel at the groin and possible arterial occlusion.
