(Select all that apply.) None, if the patient has a volume-control device. The patient may experience infiltration. None, if the patient has an inline filter. The catheter may clot off. The patient may receive less than the prescribed amount of IV fluids. The patient may receive more than the prescribed amount of IV fluids. None, because the nursing assistive personnel may regulate the IV in the nurse's absence. Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates. Order: 1000 mL of D51/2NS (dextrose 5% in 0.45% sodium chloride) in 8 hours Available: 1 liter of D51/2NS (dextrose 5% in 0.45% sodium chloride); IVQuestion 3 1 / 1 pts Question 4 1 / 1 pts macrodrip tubing 10 gtt per milliliter The patient should receive gtt per minute. 1 21 1000 mL / 8 hours = 125 mL per hour 125 mL / 1× 10 gtt/mL / 60 minutes = 20.8 gtt/min = 21 gtt per minute Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates. Order: 500 mL of D5W in 2 hours Available: 500 mL of D5W; IV macrodrip tubing 15 gtt per milliliter The patient should receive gtt per minute. 1 63 500 mL/2 hour = 250 mL per hour 250 mL / 1 × 15 gtt/mL / 60 minutes = 62.5 gtt/min = 63 gtt per minuteQuestion 5 1 / 1 pts Question 6 1 / 1 pts Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates. Order: 500 mL of D5W in 5 hours Available: Electronic infusion device; 500 mL of D5W, microdrip tubing (drop factor 60 gtt/mL) The electronic infusion device rate is gtt per minute. 1 100 500 mL / 5 hours = 100 mL per hour 100 mL / 1 × 60 gtt/mL / 60 minutes = 100 gtt per minute The setting on the electronic infusion devices (EID) would be 100. Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates. Order: 0.9% normal saline at 80 mL per hour It will take hours for 2000 mL to infuse. 1 25 2000 mL / 80 mL/hr = 25 hours The nursing staff attended an in-service on IV fluid management with discussion on patient safety. Which of the following statements, if made by one of the staff, indicates further instruction is needed? “Calculation and regulation of IV flow rates is inappropriate for nursing assistive personnel to perform.” “Most electronic infusion devices use microdrip tubing, and therefore the setting on the electronic infusion device in milliliters per hour is the same as the calculated gtt per minute.”Question 7 1 / 1 pts Question 8 1 / 1 pts “It is unnecessary to monitor infusion rates when an electronic infusion device is being used.” “An electronic infusion device may continue to infuse IV fluids after an infiltration has begun.” The nurse has received an order to infuse an IV medication. Which of the following would be the safest choice of equipment to use? An electronic infusion device. A smart pump. A volume-control device. Gravity IV controller. A patient has an order for the administration of 1000 mL of 0.9% normal saline at 100 mL/hr. The nurse begins the infusion at 0900. At noon the nurse notices that 500 mL has infused. Of the following options, which should be the nurse’s highest priority action?Question 9 1 / 1 pts Question 10 1 / 1 pts Determine if there is a kink in the tubing or if the IV is positional. Determine if the electronic infusion device is plugged in or if the “low battery” signal is displayed. Assess the site for complications such as infiltration, phlebitis, or clotting of the catheter. Assess the patient for symptoms of fluid volume overload. A patient has received 1000 mL of IV fluid in 2 hours. The patient has dyspnea, tachycardia, crackles in the lungs, and peripheral edema. What is the nurse’s priority action at this time? Discontinue present IV. Slow infusion to KVO and notify health care provider. Check for positional changes that affect rate, height of IV container, kinking of tubing, or obstruction. Assess the patient for symptoms of fluid volume overload. A nurse working in the emergency room has elected to use macrodrip IV tubing. For which patient would this be most appropriate?Question 11 1 / 1 pts Question 12 1 / 1 pts A child who has experienced nausea and vomiting for the last 24 hours. A hypotensive adult trauma victim with cool, clammy skin. An older adult who is being treated for congestive heart failure. A young adult being treated for asthma with an order for D5W at 60 mL/hr. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates. A patient is to receive 1000 mL of 0.45% normal saline over 12 hours. The nurse begins the infusion at 0800. Four hours later, the nurse notes there is 750 mL left in the IV bag. The nurse recalculates the flow rate. The nurse should set the electronic infusion device at mL/hr. 1 94 12 hours − 4 hours = 8 hours left 750 mL / 8 hour = 93.75 = 94 mL/hr The nurse hangs 1000 mL of 0.9% normal saline at 0900. The ordered rate is 80 mL/hr and is infusing with microdrip tubing and an EID. The nurse would expect to hang a new IV bag at approximately at what time? (in military time —remember 2400 is midnight)mL ÷ 80 mL/hr = 12.5 hours 0900 + 12½ hours = 2130Question 1 1 / 1 pts Maintenance of IV Therapy: Lesson 3 Post-Test Correct answers will be available on Jun 3 at 12am. Score for this quiz: 5 out of 5 Submitted Jun 1 at 1:39am This attempt took 2 minutes. The nurse performed hand hygiene and applied clean gloves to perform an intravenous (IV) tubing change. Which step(s) described in the following was missed or performed incorrectly? Remove IV dressing covering catheter hub and slow rate of infusion to keepvein-open (KVO) by regulating the roller clamp. Fill drip chamber of old tubing, remove IV container from IV pole, and remove old tubing from the solution. Place insertion spike of new tubing into the old fluid container opening and hang it on the IV pole. Fill tubing rapidly with solution, creating air bubbles in the tubing. Turn roller clamp to the "off" position on the new tubing and remove as much air as possible. Turn roller clamp on the old tubing to the "off" position. Stabilize hub of the catheter, disconnect the old tubing from the catheter hub, and quickly insert adapter of new tubing into catheter hub. Open roller clamp on new tubing, and regulate IV drip according to health care provider's orders. Secure tubing with a piece of tape. Place label with date and time on tubing below drip chamber. Discard old tubing and used supplies, remove gloves, and perform hand hygiene. Failing to change the IV dressing. Failing to close the roller clamp on the new tubing before inserting it into the fluid container. Opening the roller clamp on the new tubing after attaching it to the catheter hub. Failing to wipe the IV catheter hub with an antiseptic swab before connecting the new tubing.Question 2 1 / 1 pts Question 3 1 / 1 pts The patient has an order to infuse gentamicin (Garamycin) 500 mg IV in 50 mL sodium chloride at a rate of 100 mL/hr every 4 hours. The patient does not have an order for continuous fluids, and therefore the medication is infused with primary tubing and the peripheral access device is saline locked between doses. Which of the following actions could cause contamination or increase the risk of infection? (Select all that apply.) When changing tubing, the nurse disconnects the old tubing and attempts to insert the adapter of the new tubing without removing the protective cap. The nurse changes the primary intermittent tubing set every 96 hours. The nurse attaches the IV bag of gentamicin (Garamycin) to new tubing, primes the tubing, and changes the bag and tubing all at one time when the dose is ordered. The nurse wipes the port on the extension tubing with an alcohol swab and flushes the vascular access device with 3 mL of normal saline when the infusion is complete. When it is time to hang a new dose of gentamicin (Garamycin), the nurse connects the tubing to the injection port using the same needleless adapter that has been hanging on the IV pole for 4 hours without a protective cover. The electronic infusion device (EID) is alarming after changing the bag of IV fluids on a continuous infusion. What could be the possible cause(s)? (Select all that apply.) The roller clamp is in the “off” position. The drip chamber is one-third to one-half full. It has been 48 hours since the IV tubing was changed.Question 4 1 / 1 pts Air is present in the tubing. The nursing students are studying in a group. Which of the following statements, if made by a nursing student, indicates further instruction is needed? “Sterile technique is used to change IV tubing.” “The bag of fluids should be changed when there is approximately 100 mL of solution left in the bag to avoid disruption in fluid therapy to the patient.”Question 5 1 / 1 pts “When a peripheral IV site is being changed, you should change the IV administration set.” “Sterile IV tubing used for a continuous infusion of normal saline may remain sterile for 96 hours.” The nurse is changing IV fluids. She has performed hand hygiene and applied clean gloves. The nurse hung the new bag of fluids on the IV pole, removed the protective cover of the tubing port, removed the spike from the old bag, and accidentally touched the spike with her hand. Which action should be taken at this time? Wipe the spike off with an alcohol swab, allow it to dry completely, and insert it into the bag of fluids. Continue with inserting the spike into the new bag of IV fluids because she was wearing gloves at the time. Obtain a new IV tubing set and a new bag of IV fluids; discard the bag of fluids she just hung and on which she had removed the protective covering of the tubing port. Obtain a new IV tubing set, remove the protective cover of the spike and insert it into the tubing port of the IV bag she just hung. Prime the tubing.Question 1 1 / 1 pts Question 2 1 / 1 pts Maintenance of IV Therapy: Lesson 4 Post-Test Correct answers will be available on Jun 3 at 12am. Score for this quiz: 5 out of 5 Submitted Jun 1 at 1:41am This attempt took 2 minutes. Identify the situations in which a peripheral intravneous (IV) line dressing requires changing. (Select all that apply.) The patient's IV dressing got wet during bathing. It has been 2 days since the last change of a transparent IV dressing. There is blood underneath the transparent dressing from movement of the catheter. Twenty-four hours have elapsed since the last gauze IV dressing change. There has been a change in the health care provider's order for the type of IV fluids. A nursing instructor is assisting a student nurse to change the peripheral IV dressing on a patient. Which action, if made by the nursing student, indicates further teaching is necessary? (Select all that apply.)Question 3 1 / 1 pts The student nurse applies sterile gloves and removes the old dressing, being careful to avoid dislodging the catheter. After completing the dressing change, the student nurse documents in the patient's chart the presence of swelling, coolness, blanching, and complaints of pain at the insertion site. The student stabilizes the IV, cleans the insertion site with chlorhexidine gluconate (CHG) solution using friction in a back and forth motion for 30 seconds. The student nurse cleans the site with a povidone-iodine swab in a concentric circle and immediately applies a new dressing to protect against infection. The student nurse labels the dressing with date and time of insertion, date and time of dressing change, gauge and length of catheter, and identification of student nurse. Which of the following indicate that the infusion needs to be temporarily discontinued, the catheter removed, and the IV relocated? (Select all that apply.) Patient is afebrile; absence of symptoms of infection at IV insertion site. Catheter is leaking at connection of hub.Question 4 1 / 1 pts Question 5 1 / 1 pts Insertion site is pale, cool to touch, and extremity edematous. Dried blood is present on the dressing. Small amount of purulent drainage is at insertion site; redness is noted. What is the rationale for avoiding taping over the connection of the tubing to the hub? Access to the catheter hub is needed when changing tubing. It will increase the risk of dislodging the catheter by an accidental pull. It will help to prevent pressure of the catheter hub against the skin It will reduce the transmission of microorganisms The nurse checks the identity of the patient, performs hand hygiene, and applies clean gloves. The nurse removes the old dressing, cleans the site with CHG solution in a back-and-forth motion, and allows the site to dry. The nurse applies a new manufactured catheter stabilization device, applies a transparent dressing, secures the tubing with tape, and labels the dressingwith date and time of dressing change. The nurse discards used equipment and performs hand hygiene. The student nurse observing the nurse change the peripheral IV dressing correctly identifies actions the nurse should have performed. The student nurse is correct in identifying which two actions? The type of gloves worn by the nurse. That the nurse does not apply the dressing. How the dressing was labeled. The direction the insertion site was cleaned. To stabilize the catheter when removing the old dressing. Using a commercial catheter stabilization device.
