ANSWERS AND RATIONALE

51) 6.25 ml

D/S x dilution = quantity of the drug

10 g = 10g x 1,000 mg/gm = 10,000 mg

1,250 mg/10,000 mg x 50 = 6.25 ml


52) D
- these signs and symptoms characterize tardive dyskinesia.
Pseudoparkinsonism is characterized by rigidity
Akathisia is motor restlessness
Acute dystonia is characterized by muscle spasms and contractions

53) 31 gtts/min

gtts/min = vol. in cc x gtt factor/no. of hours x 60 min

= 3,000 x 15/24 hrs x 60 min
= 450,000/1,440
= 31 gtts/min

54) A, B, C, F
- these are nursing considerations when administering digoxin. The therapeutic serum level of digoxin is 0.5 to 2.0 mg/ml. Above this level results to digoxin toxicity.
Digoxin decreases heart rate and increases force of cardiac contractility. Hypokalemia increases risk of digitalis toxicity.
Visual disturbances indicate digitalis toxicity. Hold the medication and notify physician.
