A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?
aPTT
PT
INR
WBC count
The Correct Answer is A
A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.
B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.
C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.
D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

Correct Answer is A
Explanation
Choice A reason:
Urine specific gravity is the measurement of the concentration of solutes in urine and is an important indicator of the client's hydration status and kidney function. A specific gravity of 1.035 is relatively high, suggesting concentrated urine. High urine specific gravity can be a sign of dehydration or other kidney-related issues.
Reporting this finding to the provider is crucial because it could indicate potential problems with the client's fluid balance and kidney function. The provider may need to assess further, conduct additional tests, or initiate appropriate interventions to address the client's hydration and renal status.
Choice B reason:
Prealbumin: A prealbumin level of 25 mg/dL is within the normal range (usually 15-35 mg/dL) and may not require immediate reporting to the provider. Prealbumin is used to assess nutritional status, and this result suggests that the client's nutritional status is within the normal range.
Choice C reason:
Temperature: The normal range is 36.5°-37.5°C (97.7°-99.5°F),thus it falls within normal range.
Choice D reason
Bowel sounds: Bowel sounds:Bowel sounds heard is a normal finding and indicates normal gastrointestinal function.
Correct Answer is C
Explanation
A. The LPN and AP lower the side rails before lifting the client up in bed is incorrect. This is a safe practice that prevents injury to the client and staff by providing more space for movement and reducing the risk of falling.
B. Prior to lifting the client, the LPN and AP raise the bed to waist level is incorrect. This is a safe practice that prevents injury to the client and staff by reducing the need for bending and lifting.
C. The LPN and the AP grasp the client under his arms to lift him up in bed is correct. This is an unsafe practice that can cause injury to the client's shoulders, neck, and axillae by applying excessive pressure and friction. The LPN and AP should use a draw sheet or a mechanical lift device to move the client up in bed.
D. The LPN and the AP ask the client to flex his knees and push his heels into the bed as they lift is incorrect. This is a safe practice that encourages active participation from the client and reduces the workload for the staff by using leverage.
