An appropriate technique for measuring the length of a tube for nasogastric insertion is to:
 
  A. Measure from the nose to the ear to the client's navel
  B. Measure from the nose to the middle of the sternum
  C. Measure and mark a point 30 inches from the end
  D. Mark 50-cm point on the tube, measure in the traditional way, and insert halfway between the two spots

Question 2

The nurse is discussing the patient's upcoming elective lumbar puncture, and explains that the patient will probably need to undergo computed tomography of the brain before the procedure is done. What is the reason for this?
 
  a. Diagnose CNS infection.
  b. Rule out increased intracranial pressure.
  c. Visualize cerebrospinal fluid.
  d. Measure pressure in the subarachnoid space.

Answer to Question 1

D
A, B, C, and D. Hanson method: First mark 50-cm point on tube, then do traditional measurement. Tube insertion should be to midway point between 50 cm (20 inches) and traditional mark.

Answer to Question 2

B
In elective lumbar puncture (LP), pre-procedure computed tomography results are reviewed for evidence of brain shift to rule out increased intracranial pressure. The purpose of the LP procedure itself is to measure pressure in the subarachnoid space; obtain CSF for visualization and laboratory examination; and inject anesthetic, diagnostic, or therapeutic agents. CT will not do these things.
