1. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?
- A. 50 ml/hour
- B. 25 ml/hour
- C. 75 ml/hour
- D. 100 ml/hour
Correct answer: C
Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.
2. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?
- A. International Normalized Ratio (INR)
- B. Serum glucose level
- C. White blood cell count
- D. Prothrombin time (PT)
Correct answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.
3. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value is most concerning?
- A. Serum glucose of 300 mg/dL
- B. Blood pressure of 140/90 mmHg
- C. Serum osmolarity of 320 mOsm/kg
- D. Serum pH of 7.30
Correct answer: C
Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.
4. A client with rapid respirations and audible rhonchi is admitted to the intensive care unit because of a pulmonary embolism (PE). Low-flow oxygen by nasal cannula and weight-based heparin protocol are initiated. Which intervention is most important for the nurse to include in this client's plan of care?
- A. Evaluate blood clotting factors daily.
- B. Encourage incentive spirometry use.
- C. Administer pain medication as needed.
- D. Monitor for signs of bleeding.
Correct answer: A
Rationale: Evaluating blood clotting factors daily is crucial when a client is on heparin therapy to monitor for potential complications such as bleeding or clotting issues. This monitoring helps ensure that the heparin dose is within the therapeutic range and reduces the risk of bleeding or clotting complications. Encouraging incentive spirometry use is beneficial for preventing atelectasis and improving lung function, but in this scenario, monitoring blood clotting factors takes precedence. Administering pain medication as needed is important for the client's comfort but is not the priority in managing a pulmonary embolism. Monitoring for signs of bleeding is important due to heparin therapy, but evaluating blood clotting factors provides more specific information on the client's response to treatment.
5. A male client is having abdominal pain after a left femoral angioplasty and stent, and is asking for additional pain medication for right lower quadrant pain (9/10). Two hours ago, he received hydrocodone/acetaminophen 7.5/7.50 mg. His vital signs are elevated from the previous hour: temperature 97.8 F, heart rate 102 beats per minute, respiration 20 breaths per minute. His abdomen is swollen, the groin access site is tender, peripheral pulses are present, but the left leg is larger than the right. Preoperatively, clopidogrel was prescribed for a history of previous peripheral stents. Another nurse is holding manual pressure on the femoral arterial access site which may be leaking into the abdomen. What data is needed to make this report complete?
- A. Client's lungs are clear bilaterally, and oxygen saturation is 97%.
- B. The surgeon needs to see the client immediately to evaluate the situation.
- C. Left peripheral pulses were present only by Doppler pre-procedure.
- D. Client's history includes multiple back surgeries and chronic pain.
Correct answer: B
Rationale: The correct answer is B. Immediate evaluation by the surgeon is necessary due to the possibility of an internal hemorrhage, which is a life-threatening condition. Choice A is incorrect as lung status and oxygen saturation are not the priority in this situation. Choice C is not relevant to the current urgent issue. Choice D, while providing additional history, is not pertinent to the immediate concern of a potential internal hemorrhage post angioplasty and stent placement.
