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 with deep vein thrombosis (DVT) in the left leg is on a heparin protocol. Which intervention is most important for the nurse to include in this client's plan of care?
- A. Observe for bleeding side effects related to heparin therapy.
- B. Assess blood pressure and heart rate at least every 4 hours.
- C. Measure calf girth to evaluate edema in the affected leg.
- D. Encourage mobilization to prevent pulmonary embolism.
Correct answer: A
Rationale: The correct answer is to 'Observe for bleeding side effects related to heparin therapy.' This is the most crucial intervention for a client with deep vein thrombosis (DVT) on a heparin protocol. Heparin, being an anticoagulant, increases the risk of bleeding as a side effect. Therefore, close monitoring for signs of bleeding, such as bruising, petechiae, or blood in stool or urine, is essential to prevent severe complications. While assessing blood pressure and heart rate (Choice B) is important, it is not as critical as monitoring for bleeding. Measuring calf girth (Choice C) may help evaluate edema but is not as vital as observing for bleeding complications. Encouraging mobilization (Choice D) is beneficial for preventing complications like pulmonary embolism, but in this scenario, monitoring for bleeding takes precedence due to the immediate risk associated with anticoagulant therapy.
3. A 14-year-old male client with a spinal cord injury (SCI) at T-10 is admitted for rehabilitation. During the morning assessment, the nurse determines that the adolescent's face is flushed, his forehead is sweating, his heart rate is 54 beats/min, and his blood pressure is 198/118. What action should the nurse implement first?
- A. Determine if the urinary bladder is distended
- B. Irrigate the indwelling urinary catheter
- C. Review the temperature graph for the last day
- D. Administer an antihypertensive agent
Correct answer: A
Rationale: Autonomic dysreflexia is a potentially life-threatening emergency that can be triggered by a distended bladder in clients with spinal cord injuries at T-6 or above. The priority action is to determine if the urinary bladder is distended as this could be the cause of the symptoms observed in the adolescent. Flushing, sweating, bradycardia, and severe hypertension are classic signs of autonomic dysreflexia. Irrigating the urinary catheter, reviewing temperature graphs, or administering an antihypertensive agent are not the initial actions to take when suspecting autonomic dysreflexia.
4. A client who is newly diagnosed with type 2 diabetes mellitus (DM) receives a prescription for metformin (Glucophage) 500 mg PO twice daily. What information should the nurse include in this client’s teaching plan? (Select all that apply.)
- A. Take an additional dose for signs of hyperglycemia
- B. Recognize signs and symptoms of hypoglycemia.
- C. Report persistent polyuria to the healthcare provider.
- D. Use sliding scale insulin for finger stick glucose elevation.
Correct answer: D
Rationale: The correct answer is D. Metformin does not require additional doses for hyperglycemia, and sliding scale insulin is not typically used with metformin. It is important for the client to recognize signs and symptoms of hypoglycemia, report persistent polyuria to the healthcare provider, and take the medication with meals. Teaching the client to use sliding scale insulin for finger stick glucose elevation is not appropriate in this case because metformin is the prescribed medication, and its mechanism of action differs from insulin therapy. The client should be educated on the importance of taking metformin with meals to reduce gastrointestinal side effects and to report any persistent polyuria, which could indicate poor blood sugar control.
5. A client with type 2 diabetes mellitus is admitted for frequent hyperglycemic episodes and a glycosylated hemoglobin (HbA1c) of 10%. Insulin glargine 10 units subcutaneously once a day at bedtime and a sliding scale with insulin aspart q6h are prescribed. What action should the nurse include in this client’s plan of care?
- A. Perform fingerstick glucose assessment q6h with meals
- B. Mix bedtime dose of insulin glargine with insulin aspart sliding scale dose
- C. Review proper foot care and prevention of injury with the client
- D. Avoid contaminating the insulin aspart for IV use
Correct answer: A
Rationale: Performing fingerstick glucose assessments q6h with meals is essential in monitoring the client's blood glucose levels closely, especially when managing hyperglycemic episodes and adjusting insulin doses with a sliding scale. This action helps in determining the effectiveness of the prescribed insulin regimen. Reviewing proper foot care and preventing injury is important for long-term diabetic management but not the immediate priority in this scenario. Mixing insulin glargine with insulin aspart is not recommended, as they are different types of insulin with distinct mechanisms of action. Ensuring the availability of insulin aspart for IV use is not relevant to the client's current care plan.
