1. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?
- A. Avoid foods high in vitamin K
- B. Increase intake of leafy green vegetables
- C. Consume a consistent amount of foods high in potassium
- D. Limit intake of high-protein foods
Correct answer: A
Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
2. During the suctioning of a tracheostomy tube, if the catheter appears to attach to the tracheal walls and creates a pulling sensation, what is the best action for the nurse to take?
- A. Release the suction by opening the vent.
- B. Continue suctioning to remove obstruction.
- C. Increase the pressure.
- D. Suction deeper.
Correct answer: A
Rationale: When the catheter of the suctioning device attaches to the tracheal walls, causing a pulling sensation, the nurse should release the suction by opening the vent. This action will alleviate the pulling sensation and prevent trauma to the delicate tracheal walls. Continuing suctioning or applying more pressure can lead to tissue damage and should be avoided. Suctioning deeper can increase the risk of injuring the patient's airway.
3. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
- A. BP 142/88 mmHg
- B. 2+ edema of fingers and hands
- C. Radial pulse volume is +3
- D. Capillary refill time is 2 seconds
Correct answer: B
Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.
4. A healthcare professional is teaching a new colleague about the correct administration of subcutaneous (subQ) injections. Which instruction should the healthcare professional include?
- A. Insert the needle at a 90-degree angle for subQ injections
- B. Aspirate for blood return before injecting the medication
- C. Pinch the skin before inserting the needle
- D. Massage the site after administering the injection
Correct answer: C
Rationale: Pinching the skin before inserting the needle is essential in elevating the subcutaneous tissue away from the muscle. This technique ensures that the medication is administered into the correct tissue layer, promoting proper absorption and decreasing the risk of injecting into muscle tissue.
5. After receiving written and verbal instructions from a clinic nurse about a newly prescribed medication, a client asks the nurse what to do if questions arise about the medication after getting home. How should the nurse respond?
- A. Provide the client with a list of reputable Internet sites that answer frequently asked questions about medications.
- B. Advise the client to obtain a current edition of a drug reference book from a local bookstore or library.
- C. Reassure the client that information about the medication is included in the written instructions.
- D. Encourage the client to call the clinic nurse or health care provider if any questions arise.
Correct answer: D
Rationale: To ensure safe medication use, the nurse should encourage the client to call the clinic nurse or health care provider if any questions arise. Direct communication with healthcare professionals involved in the client's care is crucial to address any concerns promptly and accurately, ensuring the client's safety and understanding of the prescribed medication.
