Pharm Question from Pearson Review

Older clients experiencing anginal pain with complaints of fatigue or weakness usually are medicated with which of the following types of medication?

  1. Sublingual Nitroglycerin
  2. Cardiac glycosides
  3. HMG-CoA Reductase Inhibitors
  4. Morphine sulfate

Answer: 1, Angina frequently is managed with sublingual nitroglycerin, which causes vasodilation and increases blood flow to the coronary arteries. Cardiac glycosides are used to treat heart failure, and morphine is used to treat myocardial infarction. The HMG-CoA reductase inhibitors are used for patients with type 2 diabetes mellitus.

A patient recovering from a lobectomy has a chest tube attached to a water-seal drainage system. The healthcare provider notices the fluid in the water-seal column has stopped fluctuating. Which of the following would explain why the fluctuations have stopped?

Select all that apply:

  1. The lung has begun to collapse
  2. Positive interplueral pressure has increased
  3. The lung has fully expanded
  4. There may be fibrin clots in the tubing
  5. The drainage system has a leak in it

Answer: 3 and 5

The fluctuation in the water seal (tidaling) occurs as intrapleural pressure changes during inspiration and expiration. There should be patency between the intrapleural space and the chest tube system, so a blockage in the system may cause the tidaling to stop. Gradual reduction of the tidaling is expected as the lung re-expands, and will eventually stop when the lung has re-expanded.
