Sample Questions Are Posted Below
| 1. | A nurse is caring for a client with an intravenous catheter. When administering medication by IV push through the port, the nurse pinches the tubing upstream from the port when instilling the medication. Which of the following reasons explains the nurse’s action? | |
| A) | Provides access to the inside of the tubing | |
| B) | Creates negative pressure in the syringe | |
| C) | Validates that the IV catheter is in the vein | |
| D) | Ensures that the medication reaches the client | |
| Ans: | D | |
| Feedback: | ||
| Pinching the tubing when instilling it with the drug ensures that the tube does not get backfilled and that the drug gets administered to the client. Piercing the port with the needle provides access to the inside of the tubing. Negative pressure is created by pulling back the plunger of the syringe. Pinching the tubing when instilling it with the drug does not validate that the IV catheter is in the vein, but the presence of blood in the tubing does. | ||
| 2. | A nurse is caring for a client undergoing intravenous (IV) therapy. The nurse knows that intravenous (IV) administration of medication is particularly appropriate in which of the following situations? | |
| A) | When the client has disorders that affect the absorption of medications | |
| B) | When the drug needs to act on the client very slowly | |
| C) | When the client wants to avoid the discomfort of an intradermal injection | |
| D) | When the drug needs to be administered only once | |
| Ans: | A | |
| Feedback: | ||
| IV administration may be chosen when clients have disorders, such as severe burns, that affect the absorption and metabolism of medications. IV therapy is also used in an emergency when a quick response is needed. IVÂ administration is not chosen when a client wants to avoid the discomfort of an intradermal injection but rather when the client may want to avoid the discomfort of repeated intramuscular injections. A single administration of a drug does not necessarily indicate the need for IV administration. | ||
| 3. | A nurse needs to administer a continuous medication drip to a client. The nurse knows that, for a continuous infusion, he or she will likely need to add medication to which of the following volumes of IV solution? | |
| A) | 15 to 50 ml | |
| B) | 150 to 250 ml | |
| C) | 500 to 1000 ml | |
| D) | 50 to 100 ml | |
| Ans: | C | |
| Feedback: | ||
| A continuous infusion is the instillation of a parenteral drug over several hours. It is also called a continuous drip, which involves adding medication to a large volume of IV solution—approximately 500 to 1,000 ml, not less. | ||
| 4. | A nurse is administering an IV antibiotic which must be refrigerated until used in order to maintain stability of the solution. How long before administration should the nurse remove a refrigerated secondary solution? | |
| A) | 3 to 5 minutes | |
| B) | 10 minutes | |
| C) | 30 minutes | |
| D) | 60 to 90 minutes | |
| Ans: | C | |
| Feedback: | ||
| The nurse should remove a refrigerated secondary solution 30 minutes before administration because it warms the solution slightly, preventing lowering of blood temperature, and also promotes comfort during instillation. Removing it too early means that it will remain cold; removing it too late may result in instability. | ||
