1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
2. A client who is diagnosed with amyotrophic lateral sclerosis (ALS) is having difficulty swallowing and articulating words. Which intervention is most important to include in this client’s plan of care?
- A. Encourage speaking slowly and articulating words
- B. Sit upright and flex chin forward while swallowing
- C. Position a communication board at the bedside
- D. Provide feeding utensils with large grip handles
Correct answer: B
Rationale: The correct intervention for a client with ALS experiencing difficulty swallowing and articulating words is to sit upright and flex the chin forward while swallowing. This position helps manage dysphagia associated with ALS by facilitating the swallowing process. Encouraging speaking slowly and articulating words (Choice A) may be helpful for speech clarity but does not address the swallowing issue. Positioning a communication board (Choice C) would not directly address the swallowing difficulty. Providing feeding utensils with large grip handles (Choice D) is not the priority intervention for managing dysphagia in ALS.
3. A 12-year-old client who had an appendectomy two days ago is receiving 0.9% normal saline at 50 ml/hour. The client’s urine specific gravity is 1.035. What action should the nurse implement?
- A. Encourage popsicles and fluids of choice
- B. Evaluate postural blood pressure measurements
- C. Obtain a specimen for urinalysis
- D. Assess bowel sounds in all quadrants
Correct answer: A
Rationale: Encouraging fluids helps address dehydration and potentially high urine specific gravity, which is often related to inadequate fluid intake. In this scenario, the client may be at risk of dehydration due to the appendectomy and the high urine specific gravity. Encouraging popsicles and fluids of choice can help increase fluid intake and improve hydration status. The other options are not the priority at this time. Postural blood pressure measurements may be relevant for assessing fluid status but are not the immediate action needed. Obtaining a specimen for urinalysis and assessing bowel sounds are not the priority actions based on the client's condition.
4. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, “I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home”. What response is best for the nurse to provide?
- A. Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely
- B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
- C. Let me contact your healthcare provider to discuss the possibility of receiving IV heparin therapy at home
- D. Why are you so anxious to leave the hospital when you know you are not well enough yet?
Correct answer: A
Rationale: The correct response is A: 'Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely.' Heparin is an anticoagulant that prevents further clot formation, but it does not quickly dissolve existing clots. It is crucial for the nurse to educate the client about the purpose of heparin and the necessity for close monitoring of bleeding risks. Choice B is incorrect as it does not address the misunderstanding about heparin's mechanism of action. Choice C is incorrect as home administration of IV heparin therapy requires careful consideration and should not be suggested without a thorough assessment. Choice D is incorrect as it does not address the client's misconception about heparin's role in dissolving clots and instead focuses on the client's desire to leave the hospital.
5. While assessing a client four hours post-thoracentesis, the nurse is unable to auscultate breath sounds on the right side of the chest. What action should the nurse take first?
- A. Instruct the client to perform cough and deep breathing exercises
- B. Assess the client’s vital signs and respiratory effort
- C. Administer oxygen via nasal cannula according to the PNR protocol
- D. Document assessment findings in the client’s medical record
Correct answer: B
Rationale: The correct first action for the nurse to take in this situation is to assess the client’s vital signs and respiratory effort. It is crucial to promptly detect any immediate complications or changes in the client's condition. Instructing cough and deep breathing exercises (choice A) can be considered after further assessment. Administering oxygen (choice C) should be based on assessment findings and healthcare provider's orders. While documenting the findings (choice D) is essential, it should not be the first action when a potential issue with breath sounds is detected.
