A nurse is monitoring the laboratory values of a client who is receiving heparin. Which of the following values should the nurse report to the provider?
PT 11 seconds
APTT 50 seconds
Hematocrit 456
Platelets 300,000/mm²
The Correct Answer is C
A.PT (Prothrombin Time) 11 seconds: The prothrombin time measures the extrinsic pathway of the coagulation cascade. A PT of 11 seconds is within the normal range, and it indicates that the extrinsic clotting pathway is functioning appropriately. There is no need to report this value.
B. APTT (Activated Partial Thromboplastin Time) 50 seconds: The APTT measures the intrinsic pathway of the coagulation cascade. A value of 50 seconds is prolonged and may suggest that the client is receiving an effective anticoagulant dose. However, the APTT target range can vary based on the specific therapeutic goal and the heparin protocol in use. It's essential to follow the healthcare provider's guidance on the target APTT range.
C. Hematocrit 456: The normal range for hematocrit is usually expressed as a percentage. A value of 456 is outside the normal range and likely represents an error or a misinterpretation. The nurse should verify this value, as an extremely high hematocrit could be indicative of an issue such as dehydration or an analytical error.
D. Platelets 300,000/mm²: A platelet count of 300,000/mm² is within the normal range. There is no need to report this value as it suggests a normal platelet count.

Correct Answer is C
Explanation
A. Discard the medication if it is yellow: Amphotericin B lipid complex is typically yellow in color. This is a normal characteristic of the medication, and it should not be discarded based on color. The nurse should be aware of the expected color and administer the medication as prescribed.
B. Administer the medication over 2 hr: Amphotericin B lipid complex is often administered over an extended period (usually over 2 to 6 hours) to minimize the risk of infusion-related reactions. However, if the prescription specifies an intermittent IV bolus, the nurse should follow the prescribed administration route and rate.
C. Prime the tubing with 0.9% sodium chloride (Correct Answer): Amphotericin B lipid complex can interact with dextrose-containing solutions, leading to the formation of a precipitate. Therefore, it is recommended to prime the IV tubing with 0.9% sodium chloride before administering the medication to prevent any potential interaction.
D. Use a gravity flow set: The choice of infusion set may depend on the specific institutional policies and the patient's condition. However, using a pump or a controlled infusion device is often recommended when administering medications like amphotericin B to ensure accurate infusion rates and reduce the risk of adverse reactions.
Correct Answer is ["60"]
Explanation
1.Convert the available lidocaine concentration to mg/mL:
2 g of lidocaine = 2000 mg
2000 mg ÷ 500 mL = 4 mg/mL
2. Determine the mL/min required to deliver 4 mg/min:
4 mg/min ÷ 4 mg/mL = 1 mL/min
3. Convert mL/min to mL/hr:
1 mL/min × 60 minutes = 60 mL/hr
