NUR 250 - Excelsior University| NUR250 Module 3 Questions and Answers Latest Fall 2025/26. Module 3 questions 1. A nurse is caring for a client who has fluid overload during a continuous IV infusion at 200 mL/hr. Which of the following actions by the nurse is appropriate? A Reduce the IV fluid rate. B Place the client in the orthopneic position. C Remove the IV catheter. D Place the client in modified Trendelenburg position. Well done! Reduce the IV rate and notify the provider immediately. To facilitate breathing, elevate the head of the bed to the high-Fowler’s position. The client might need intravenous medications to treat the fluid overload. 2. A nurse is monitoring a client who is receiving an IV medication. The client reports dizziness and a feeling of chest tightness. The nurse notes that the client’s face is flushed and warm. These findings indicate which of the following systemic complications of IV therapy? A Speed shock B Extravasation C Anaphylactic shock D Fluid overload Well done! Speed shock occurs when a client receives an intravenous medication too rapidly, causing dizziness, chest tightness, flushed and warm face, and other effects related to a toxic level of medication in the body. Extravasation causes darkening or redness of the skin, swelling, and pain at the IV site, which can extend to extensive tissue damage over time. Anaphylactic shock causes bronchospasms, wheezing, shortness of breath, severe hypotension, tachycardia, and respiratory or cardiac arrest. Fluid overload causes shortness of breath; increased blood pressure, heart rate, and respiratory rate; crackles in the lungs; neck vein distention; and edema in the extremities. 3. A nurse is caring for a client who is receiving norepinephrine by continuous IV infusion. During a routine assessment of the IV site, the nurse notes that the catheter is no longer in the vein and the vesicant medication has infused into the subcutaneous tissue. Which of the following actions should the nurse take? A Apply a tourniquet proximal to the IV site. B Call the rapid response team and start oxygen. C Prepare to administer a diuretic. D Stop the infusion and prepare to administer an antidote. Well done!Module 3 questions Stop the IV infusion and prepare to administer phentolamine (an antidote for extravasation ischemia due to norepinephrine), which prevents damage to the surrounding tissue. Apply a tourniquet proximal to the IV site if a catheter embolism is suspected. Call the rapid response team and start oxygen if anaphylactic shock is suspected. Prepare to administer a diuretic if fluid overload is suspected. 4. A nurse is planning care for a client who is receiving IV therapy. Which of the following measures should the nurse include to prevent phlebitis? A Change the IV site weekly. B Apply a warm compress to IV site. C Use a clean technique when replacing the transparent dressing over the IV site. D Use a small-gauge catheter when initiating IV therapy. Well done! Use a catheter with the smallest gauge possible to prevent irritation of the vein and subsequent phlebitis. Change the IV site only as clinically indicated by signs of phlebitis or infiltration. Use a warm compress to treat phlebitis, not prevent it. Use sterile technique when replacing the transparent dressing over the IV site. 5. A nurse is caring for a client who is receiving an antibiotic by intermittent IV infusion. The client reports feeling short of breath and is wheezing. Which of the following actions should the nurse take? Select all that apply. A Initiate oxygen. B Call the rapid response team. C Prepare to administer acetylcysteine. D Remove the IV catheter. E Elevate the head of the bed to 45°. Well done! A client who starts to have shortness of breath and wheezing while receiving an antibiotic by intermittent bolus is likely experiencing anaphylaxis. First, stop the infusion. Then initiate oxygen using a nonrebreather mask to treat the dyspnea. Call the rapid response team for assistance and raise the head of the bed to facilitate gas exchange. Prepare to administer epinephrine, which reverses manifestations of anaphylaxis. (Acetylcysteine is the antidote for acetaminophen overdose.) Leave the catheter in place to facilitate the administration of emergency medications and IV fluids. Replace the IV tubing and infuse 0.9% NaCl. 6. Which of the following is a common name for the IV solution 0.9% sodium chloride?Module 3 questions A Half normal saline B Normal saline C Lactated Ringer's D Sodium lactate Well done! Normal saline is the common name for 0.9% NaCl. Half normal saline is the common name for 0.45% NaCl. Lactated Ringer’s is also known as LR. Sodium lactate is a component of lactated Ringer’s. 7. A nurse is administering lactated Ringer’s (LR), which contains lactate. LR can be used to treat a client who has which of the following disorders? A Acidosis B Alkalosis C Caloric deficit D Caloric excess Well done! The nurse should administer LR to clients who have acidosis. When a client receives lactate intravenously, the liver metabolizes it to form bicarbonate, which helps correct the acidosis. LR should not be used to treat alkalosis, caloric deficit, or caloric excess. 8. Which of the following is the abbreviation for the IV solution half normal saline? A 0.25% NaCl B 0.45% NaCl C 0.5% NaCl D 0.9% NaCl Well done! Because normal saline contains 0.9% NaCl, half normal saline contains 0.45% NaCl. 9. How many calories does 1 L of 5% dextrose in water (D5W) provide? One liter of D5W provides 170 calories and is not a significant factor in providing necessary nutrition to a client. It is used primarily to correct serum osmolality and supply water.Module 3 questions 10. Which of the following IV solutions should a nurse use when preparing to administer a blood transfusion? A 5% dextrose in water (D5W) B Lactated Ringer’s (LR) C 5% dextrose in 0.9% sodium chloride (D5NS) D 0.9% sodium chloride (0.9% NaCl or NS) Well done! The nurse should use 0.9% NaCl solution when administering blood to prevent hemolysis of red blood cells. Administering blood with D5W or D5NS can cause hemolysis. LR can result in the formation of small blood clots. 11. Match the type of IV solution with its description. Drag the options on the left to their match on the right (or match pairs by first selecting the option on the left and then selecting its match on the right). Moves fluid from the veins to the cells and interstitial spaces= Hypotonic Pulls fluid out of the cells and into the veins=Hypertonic Remains in the intravascular space=Isotonic 12. Hemolysis can occur with the administration of which of the following types of solution? A Isotonic B Hypotonic C Hypertonic Well done! Hypotonic solutions move fluid from veins into cells, which can cause hemolysis, or rupture of the cells. 13. A nurse administers a solution of 3% NaCl to a client. Which of the following types of solution is this? A Isotonic B Hypotonic C Hypertonic Well done! A solution of 3% sodium chloride has a much greater amount of sodium solutes dissolved within the solution than body fluids or blood. Therefore, it is considered a hypertonic solution. A 0.45% sodium chloride solution has an osmolarity less than that of blood and body fluids and is considered hypotonic. A 0.9% sodium chlorideModule 3 questions (0.9% NaCl) solution has an osmolarity very similar to that of blood and body fluids and is considered isotonic. 14. A nurse administers lactated Ringer’s by continuous IV infusion. Which of the following types of solution is this? A Isotonic B Hypotonic C Hypertonic Well done! Lactated Ringer’s has an osmolarity of 273 mOsm/L, making it an isotonic solution. 15. A nurse administers dextrose 5% in water (D5W) IV solution. After the dextrose is metabolized, which of the following types of solution is this? A Isotonic B Hypotonic C Hypertonic Well done! After the client receives D5W by intravenous infusion, the dextrose is quickly metabolized, leaving only free water, which is a hypotonic solution. 16. A nurse is preparing to use the piggyback method to administer a secondary IV medication. Which of the following is where the nurse should place the secondary bag? A Higher than the primary bag B Lower than the primary bag C Equal in height to the primary bag Well done! The nurse should hang the secondary IV bag at a higher level than the primary IV bag. The primary solution will begin to infuse after the secondary bag is empty. 17. A nurse is observing a newly licensed nurse administer an intermittent IV bolus to a client who has a continuous IV. The IV bolus is compatible with the continuous IV fluids. Which of the following actions by the newly licensed nurse requires intervention? A Choosing the port closest to the client to administer the medication B Flushing the line with 0.9% NaCl prior to administering the medication C Pinching the IV tubing above the port while administering the medication D Donning clean gloves prior to the procedureModule 3 questions Well done! It is not necessary to flush the line with 0.9% NaCl prior to administering a medication that is compatible with the IV solution. Use the port closest to the client to ensure rapid infusion of the medication. Pinching the IV tubing above the port will allow the medication to flow toward the client instead of back up into the tubing. Follow standard precautions and wear clean gloves when performing the procedure. 18. A nurse is reviewing the label affixed to a bag of IV medication to be given as an intermittent IV bolus. Which of the following information must be included to meet ISMP recommendations? Select all that apply. A Client’s medical record number B Provider's name C Infusion time for medication D Diluent solution E Expiration date of medication
