A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min per nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?
- A. COPD clients are stimulated to breathe by hypoxia.
- B. COPD clients depend on a low carbon dioxide level.
- C. COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
- D. COPD clients thrive on a high oxygen level.
Correct Answer: A
Rationale: COPD clients are compensating for low oxygen and high carbon dioxide levels. Hypoxia is the main stimulus to breathe in persons with chronic hypercapnia. Increasing the level of oxygen decreases the stimulus to breathe.

- A. Disconnect the infusion, inject 3 mL of normal saline, and give the morphine sulfate undiluted.
- B. Question the prescribed medication because morphine sulfate cannot be given through a PICC line.
- C. Give the morphine sulfate undiluted into the existing IV tubing's medication port closest to the child.
- D. Dilute the morphine sulfate with 5 mL of NS and give over 5 minutes into the IV tubing port closest to the child.
Correct Answer: D
Rationale: A: Unnecessary IV disconnections increase the risk for infection. Morphine sulfate is compatible with D5W. B: Morphine sulfate can be administered into a PICC access device. C: Administering undiluted morphine sulfate to a child increases the risk of adverse effects. D: The nurse should dilute the morphine sulfate before administration to prevent too-rapid administration and adverse effects. A single dose should be given over 4 to 5 minutes.
