A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor?
- A. Hemoglobin
- B. aPTT
- C. INR
- D. Platelet count
Correct Answer: B
Rationale: The correct answer is B: aPTT. The activated partial thromboplastin time (aPTT) is monitored to assess the therapeutic effect of heparin and to adjust the infusion rate if needed. Monitoring hemoglobin levels (choice A) is important for assessing anemia but is not specific to heparin therapy. INR (choice C) is used to monitor the effects of warfarin, not heparin. Platelet count (choice D) is important to monitor for heparin-induced thrombocytopenia, but aPTT is the primary laboratory value used to monitor heparin therapy.

A client with deep vein thrombosis receiving heparin therapy needs monitoring. Which test should the nurse use to regulate the medication dosage?
- A. Prothrombin time (PT)
- B. International Normalized Ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Fibrinogen levels
Correct Answer: C
Rationale: The correct answer is C: Activated partial thromboplastin time (aPTT). aPTT is specifically used to monitor and regulate heparin therapy as it assesses the intrinsic pathway of coagulation, which heparin affects. Options A and B, Prothrombin time (PT) and International Normalized Ratio (INR), are used to monitor warfarin therapy, not heparin. Option D, Fibrinogen levels, is not the primary test used to monitor heparin therapy.
A nurse is assessing a client who is receiving continuous enteral feedings through a nasogastric tube. Which of the following findings should the nurse report to the provider?
- A. Gastric residual of 200 mL
- B. Heart rate of 100/min
- C. Urinary output of 250 mL in 12 hr
- D. Blood glucose level of 180 mg/dL
Correct Answer: D
Rationale: The correct answer is D. A blood glucose level of 180 mg/dL is higher than expected and should be reported to prevent hyperglycemia complications. High blood glucose levels can lead to hyperglycemia, causing various issues such as increased risk of infection and delayed wound healing. Choices A, B, and C are within normal limits for a client receiving continuous enteral feedings and do not require immediate reporting.
A client who has a new prescription for lisinopril is being taught by a nurse. Which of the following client statements indicates an understanding of the teaching?
- A. I should avoid using salt substitutes while taking this medication.
- B. I should take this medication with food to prevent nausea.
- C. I should increase my intake of potassium-rich foods while taking this medication.
- D. I should limit my fluid intake while taking this medication.
Correct Answer: A
Rationale: The correct answer is A. Lisinopril can increase potassium levels, so clients should avoid salt substitutes that contain potassium. Choice B is incorrect because lisinopril is usually taken on an empty stomach. Choice C is incorrect because lisinopril can lead to hyperkalemia, so increasing potassium-rich foods is not recommended. Choice D is incorrect because lisinopril can cause increased urination, so fluid intake should not be limited.
A client is receiving discharge instructions following a stroke. Which of the following client statements indicates an understanding of the teaching?
- A. I will avoid using aspirin for pain.
- B. I will consume dairy products to increase my calcium intake.
- C. I will drink 1.5 to 2 liters of fluid each day.
- D. I will need to limit my intake of fiber.
Correct Answer: A
Rationale: The correct answer is A. Avoiding aspirin is crucial for this client as it can increase the risk of bleeding after a stroke. Choice B about consuming dairy products for calcium intake is not directly related to stroke management. Choice C regarding fluid intake is a good practice for overall health but not specifically related to stroke care. Choice D about limiting fiber intake is not typically a concern after a stroke unless there are specific complications that warrant it.
A nurse is reviewing the laboratory results of a client who has hypocalcemia. Which of the following findings should the nurse expect?
- A. Positive Trousseau's sign
- B. Increased deep tendon reflexes
- C. Hyperactive bowel sounds
- D. Weak, thready pulse
Correct Answer: A
Rationale: A positive Trousseau's sign is a key finding in clients with hypocalcemia, indicating neuromuscular irritability. The other choices are not typically associated with hypocalcemia. Increased deep tendon reflexes are more indicative of hypercalcemia. Hyperactive bowel sounds can be seen in hyperactive bowel conditions or diarrhea, not specifically related to hypocalcemia. A weak, thready pulse may indicate cardiovascular issues, such as dehydration, but it is not a typical finding in hypocalcemia.
