1. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?
- A. Platelets 250,000/mm³
- B. aPTT 60 seconds
- C. Hemoglobin 15 g/dL
- D. INR 1.5
Correct answer: B
Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.
2. A nurse is planning care for a client who has Alzheimer's disease and demonstrates confusion and wandering behavior. Which of the following should the nurse include in the plan of care?
- A. Place the client in seclusion when she is confused.
- B. Request a prescription for PRN restraints when the client is wandering.
- C. Dim the lighting in the client's room.
- D. Leave one side rail up on the client's bed.
Correct answer: C
Rationale: The correct answer is to dim the lighting in the client's room. Dim lighting can help reduce confusion and agitation in clients with Alzheimer's disease. Placing the client in seclusion (Choice A) is not recommended as it can lead to feelings of isolation and distress. Requesting PRN restraints (Choice B) should be avoided in clients with Alzheimer's as it can increase agitation and pose safety risks. Leaving one side rail up on the client's bed (Choice D) may not directly address the client's confusion and wandering behavior.
3. A nurse is preparing to administer packed RBCs to a client. Which of the following actions should the nurse take first?
- A. Prime the IV tubing with dextrose 5% in water
- B. Ensure the client's consent is on file
- C. Check the client's identification using two identifiers
- D. Administer the blood through a 22-gauge catheter
Correct answer: C
Rationale: The correct first action for the nurse to take when preparing to administer packed RBCs is to check the client's identification using two identifiers. This step is crucial to ensure that the right blood is given to the right client, preventing any transfusion errors. Priming the IV tubing with dextrose 5% in water and administering the blood through a 22-gauge catheter are important steps but should come after confirming the client's identity. Ensuring the client's consent is on file is also important but is not the immediate priority when preparing to administer packed RBCs.
4. What is the best method to monitor fluid balance in a patient receiving diuretics?
- A. Monitor daily weight
- B. Monitor intake and output
- C. Monitor blood pressure
- D. Monitor edema
Correct answer: A
Rationale: The best method to monitor fluid balance in a patient receiving diuretics is to monitor daily weight. Daily weighing is a precise way to assess changes in fluid status as it reflects variations in total body water. Monitoring intake and output (choice B) is also important but may not provide as accurate a measurement as daily weight. Monitoring blood pressure (choice C) is essential but does not directly measure fluid balance. Monitoring edema (choice D) is helpful to assess fluid status visually but may not be as sensitive as daily weight measurements in detecting subtle changes in fluid balance.
5. What is the most critical lab value to monitor for a patient on heparin therapy?
- A. Monitor aPTT levels
- B. Monitor platelet count
- C. Monitor INR levels
- D. Monitor sodium levels
Correct answer: A
Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.
