Question 1:

A nurse is assessing a client who has an IV catheter in place for fluid administration. The nurse observes swelling, redness, and warmth around the insertion site. Which complication of IV therapy should the nurse suspect?

A. Phlebitis B. Infiltration C. Fluid overload D. Air embolism

Answer and Explanation

Choice A:

This choice is correct. The client's symptoms of swelling, redness, and warmth around the insertion site are indicative of phlebitis, which is inflammation of the vein caused by irritants in the IV solution or mechanical trauma from the catheter.

Choice B:

This choice is incorrect because infiltration refers to the inadvertent administration of IV fluid into the surrounding tissues, causing swelling and coolness around the insertion site.

Choice C:

This choice is incorrect because fluid overload is characterized by symptoms such as shortness of breath, elevated blood pressure, and bounding pulse, not local symptoms around the IV site.

Choice D:

This choice is incorrect because air embolism occurs when air enters the vascular system, leading to symptoms such as dyspnea, cyanosis, and chest pain, rather than localized symptoms at the insertion site.

This choice is incorrect because Type III (Immune Complex-Mediated) hypersensitivity reactions involve the formation of immune complexes that deposit in tissues and trigger inflammation, but they do not typically present with generalized hives and facial swelling.

Choice D:

This choice is incorrect because Type IV (Delayed) hypersensitivity reactions occur 24 to 72 hours after exposure to an allergen and are mediated by T cells, leading to localized skin reactions like contact dermatitis. They are not associated with the rapid onset of symptoms described by the client.

Question 31:

A nurse is caring for a client with a history of multiple drug allergies who requires IV therapy. Which intervention is essential to prevent an allergic reaction in this client?

A. Administering the IV medications rapidly to minimize exposure. B. Consulting with the healthcare provider to switch to oral medications. C. Using a smaller-gauge IV catheter for medication administration. D. Performing a thorough allergy assessment and using allergy alerts.

Answer and Explanation

Choice A:

This choice is incorrect because administering IV medications rapidly may increase the risk of an allergic reaction, especially in a client with a history of multiple drug allergies.

Choice B:

This choice is incorrect because switching to oral medications may not be appropriate or feasible for all IV medications. The nurse should consider alternative medications only after performing a thorough allergy assessment and consulting with the healthcare provider.

Choice C:

This choice is incorrect because the choice of IV catheter gauge is not directly related to preventing allergic reactions. It should be based on the medication's compatibility and viscosity.

Choice D:

This choice is correct. A thorough allergy assessment is essential in a client with a history of multiple drug allergies to identify potential allergens and prevent exposure to allergenic medications. The nurse should communicate allergies to the healthcare team and document them in the client's medical record, using allergy alerts or wristbands, to ensure safe medication administration.

Question 32:

A client receiving an IV medication develops localized swelling, erythema, and pain at the IV site. The nurse assesses the client's vital signs and finds no signs of systemic allergic reaction. What is the nurse's priority action?

A. Discontinue the IV medication immediately. B. Administer an antihistamine to relieve the symptoms. C. Notify the healthcare provider about the localized reaction. D. Elevate the arm to reduce the swelling at the IV site.

Answer and Explanation

Choice A:

This choice is correct. The client's localized symptoms of swelling, erythema, and pain at the IV site may indicate a local allergic reaction or chemical irritation. The nurse should discontinue the IV medication immediately to prevent the progression of the reaction and assess the client further for any systemic signs of an allergic reaction.

Choice B:

This choice is not the priority action. While administering an antihistamine may relieve symptoms of an allergic reaction, the nurse's priority is to discontinue the IV medication and assess the client's condition.

Choice C:

This choice is not the priority action. While notifying the healthcare provider is important, the nurse's immediate priority is to discontinue the IV medication and assess the client's condition.

Choice D:

This choice is not the priority action. Elevating the arm may provide comfort, but the nurse's priority is to discontinue the IV medication and assess the client's condition for any signs of a systemic allergic reaction.

Question 33:

A client receiving IV therapy develops a fever, rash, and elevated liver enzymes. The nurse should recognize these symptoms as potential signs of which type of hypersensitivity reaction?

A. Type I (Immediate) hypersensitivity B. Type II (Cytotoxic) hypersensitivity C. Type III (Immune Complex-Mediated) hypersensitivity D. Type IV (Delayed) hypersensitivity

Answer and Explanation

Choice A:

This choice is incorrect because Type I (Immediate) hypersensitivity reactions typically involve immediate symptoms like hives, facial swelling, and difficulty breathing, not fever, rash, and elevated liver enzymes.

Choice B:

This choice is incorrect because Type II (Cytotoxic) hypersensitivity reactions involve antibodies attacking specific cells or tissues, leading to cell destruction. Elevated liver enzymes may occur in some drug-induced cytotoxic reactions, but they are not commonly associated with fever and rash.

Choice C:

This choice is correct. The client's symptoms of fever, rash, and elevated liver enzymes are potential signs of a Type III (Immune Complex-Mediated) hypersensitivity reaction. In this type of hypersensitivity, immune complexes formed by antibodies and antigens deposit in tissues and trigger inflammation, which can affect multiple organs, including the liver.

Question 34:

A nurse is caring for a client who requires prolonged IV therapy. What is the nurse's best action to prevent the development of complications associated with IV therapy?

A. Use the same insertion site for all IV catheter changes. B. Change the IV catheter every 72 hours as per policy. C. Rotate the IV insertion site with each catheter change. D. Administer medications in large volumes to minimize insertion frequency.

Answer and Explanation

Choice A:

This choice is incorrect because using the same insertion site for all IV catheter changes can lead to complications such as phlebitis and infiltration due to repetitive trauma to the vein.

Choice B:

This choice is incorrect because changing the IV catheter every 72 hours as per policy may not be necessary unless the catheter is no longer functioning properly or the site shows signs of complications. Changing the catheter prematurely can increase the risk of complications.

Choice C:

This choice is correct. Rotating the IV insertion site with each catheter change helps to distribute the risk of complications across multiple sites and allows previously used sites time to heal and recover.

Choice D:

This choice is incorrect because administering medications in large volumes to minimize insertion frequency is not a safe practice. Medication volumes should be appropriate for the client's needs, and insertion frequency should follow evidence-based guidelines.

Question 35:

A client receiving IV therapy suddenly develops shortness of breath, chest pain, and rapid heart rate. The nurse should suspect which complication and take immediate action?

A. Phlebitis B. Air embolism C. Fluid overload D. Infiltration

Answer and Explanation

Choice A:

This choice is incorrect because phlebitis typically presents with localized symptoms around the insertion site, such as redness and warmth, not shortness of breath, chest pain, and rapid heart rate.

Choice B:

This choice is correct. The client's symptoms of shortness of breath, chest pain, and rapid heart rate suggest an air embolism, which occurs when air enters the bloodstream through the IV catheter. This is a medical emergency, and the nurse should take immediate action to protect the client's airway, administer oxygen, and notify the healthcare provider.

Choice C:

This choice is incorrect because fluid overload is not associated with symptoms of shortness of breath, chest pain, and rapid heart rate. It is characterized by symptoms such as edema and elevated blood pressure.

Choice D:

This choice is incorrect because infiltration involves the inadvertent administration of IV fluid into the surrounding tissues and is not associated with symptoms of shortness of breath, chest pain, and rapid heart rate.

Question 36:

A nurse is caring for a client receiving IV fluids. The client complains of pain, burning, and redness at the insertion site. Upon assessment, the nurse notes swelling and coolness around the site. What is the nurse's priority action?

A. Elevate the client's arm to reduce swelling. B. Apply a warm compress to the insertion site. C. Discontinue the IV infusion immediately. D. Administer an analgesic for pain relief.

Answer and Explanation

Choice A:

This choice is incorrect because elevating the client's arm may not address the underlying complication of infiltration. The nurse's priority is to discontinue the IV infusion to prevent further complications.

Choice B:

This choice is incorrect because applying a warm compress is not the priority action. The nurse should first discontinue the IV infusion to assess the site and determine appropriate interventions.

Choice C:

This choice is correct. The client's symptoms of pain, burning, redness, swelling, and coolness around the insertion site are indicative of infiltration, which occurs when IV fluid leaks into the surrounding tissues. The nurse's priority is to discontinue the IV infusion to prevent further complications and assess the site for potential tissue damage.

Choice D:

This choice is incorrect because administering an analgesic may provide temporary pain relief, but it does not address the underlying complication of infiltration. The nurse should first discontinue the IV infusion and assess the site for potential complications.

Question 37:

A nurse is preparing to administer IV medications to a client. What should the nurse do to prevent medication incompatibilities during IV therapy?

A. Mix all the medications in one syringe for administration. B. Flush the IV line with a large amount of normal saline before administration. C. Consult with the pharmacist to verify medication compatibility. D. Increase the IV flow rate to hasten medication infusion.

Answer and Explanation

Choice A:

This choice is incorrect because mixing all the medications in one syringe is not recommended, as it may lead to medication incompatibilities or chemical reactions between medications.

Choice B:

This choice is incorrect because flushing the IV line with a large amount of normal saline does not prevent medication incompatibilities. It is essential to consult with the pharmacist to verify compatibility before administration.

Choice C:

This choice is correct. The nurse should consult with the pharmacist to verify the compatibility of the IV medications before administration. Certain medications may interact with each other or with the IV solution, leading to potential incompatibilities or adverse reactions.

Choice D:

This choice is incorrect because increasing the IV flow rate to hasten medication infusion does not prevent medication incompatibilities. It is essential to confirm compatibility before administering the medications.

Question 38:

A nurse is caring for a client receiving IV therapy. Which action is essential to prevent catheter-related bloodstream infections (CRBSIs)?

A. Administering IV fluids through the largest available catheter. B. Changing the IV catheter dressing daily. C. Using sterile technique during IV insertion and care. D. Frequently accessing the IV catheter for blood draws.

Answer and Explanation

Choice A:

This choice is incorrect because administering IV fluids through the largest available catheter is not necessary for preventing CRBSIs. The appropriate catheter size should be based on the client's clinical needs and the prescribed therapy.

Choice B:

This choice is incorrect because changing the IV catheter dressing daily is not necessarily recommended unless the dressing is soiled or loose. Frequent dressing changes can increase the risk of contamination and infection. The nurse should follow evidence-based guidelines for catheter care and dressing changes.

Choice C:

This choice is correct. Using sterile technique during IV insertion and care is essential for preventing CRBSIs. Sterile technique helps to reduce the risk of introducing pathogens into the bloodstream, which can lead to infection.

Choice D:

This choice is incorrect because frequently accessing the IV catheter for blood draws can increase the risk of CRBSIs. The nurse should minimize unnecessary catheter access and follow aseptic technique when drawing blood or administering medications through the catheter.

A nurse is caring for a client with an IV catheter in place for medication administration. The nurse notes swelling and coolness around the insertion site. Which complication of IV therapy should the nurse suspect?

A. Phlebitis B. Infiltration C. Fluid overload D. Air embolism

Answer and Explanation

Choice A:

This choice is incorrect because phlebitis typically presents with redness, warmth, and swelling around the insertion site, not coolness.

Choice B:

This choice is correct. The client's symptoms of swelling and coolness around the insertion site are indicative of infiltration, which occurs when IV fluid leaks into the surrounding tissues.

Choice C:

This choice is incorrect because fluid overload is not associated with localized symptoms like swelling and coolness at the IV site.

Choice D:

This choice is incorrect because an air embolism is not associated with symptoms of swelling and coolness at the IV site.
