A nurse is reviewing the PT, aPTT, and INR laboratory values for a client who is experiencing an acute episode of disseminated intravascular coagulation (DIC). Which of the following laboratory results should the nurse expect?
The laboratory values are within the expected reference range.
The laboratory values are prolonged.
The laboratory values are the same as the previous test values.
The laboratory values are decreased.
The Correct Answer is B
Choice A Reason: This is incorrect because the laboratory values are not within the expected reference range in a client who has DIC. DIC is a condition that causes abnormal activation of the clotting cascade, leading to widespread microthrombi formation and consumption of clotting factors and platelets. This results in bleeding complications and organ dysfunction.
Choice B Reason: This is correct because the laboratory values are prolonged in a client who has DIC. PT, aPTT, and INR are tests that measure the time it takes for blood to clot. PT measures the extrinsic pathway, aPTT measures the intrinsic pathway, and INR is a standardized ratio of PT. In DIC, these tests are prolonged because of the depletion of clotting factors and platelets.
Choice C Reason: This is incorrect because the laboratory values are not the same as the previous test values in a client who has DIC. DIC is an acute and dynamic condition that can change rapidly depending on the underlying cause and treatment. The laboratory values may fluctuate between normal, prolonged, or shortened depending on the balance between clotting and bleeding.
Choice D Reason: This is incorrect because the laboratory values are not decreased in a client who has DIC. Decreased laboratory values would indicate a shortened clotting time, which can occur in some cases of DIC when there is excessive clotting and thrombosis. However, this is not the typical finding in DIC, as most clients present with bleeding manifestations and prolonged clotting time.

Correct Answer is ["167 "]
Explanation
To calculate the dose of enoxaparin, follow these steps:
1) Convert the client's weight from pounds to kilograms:
245 lbs / 2.2046 (kg/lb) = 111.13 kg (rounded to the nearest whole number, it's 111 kg).
2) Multiply the weight in kilograms by the prescribed dose per kilogram:
111 kg x 1.5 mg/kg = 166.5 mg.
Round the answer to the nearest whole number, so the nurse should administer 167 mg per dose of enoxaparin every 12 hours to the client with a pulmonary embolism.
Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because administering intravenous pain medication is not the priority action for a client who has sustained partial-thickness burns. Pain medication may be indicated for pain relief and comfort, but it does not address the potential life-threatening complications of burns such as shock, infection, or respiratory distress.
Choice B Reason: This choice is incorrect because drawing blood for a CBC count is not the priority action for a client who has sustained partial-thickness burns. A CBC count may be useful to monitor the hematological status and detect any signs of infection or anemia, but it does not address the immediate needs of the client
Choice C Reason: This choice is incorrect because inserting an indwelling urinary catheter is not the priority action for a client who has sustained partial-thickness burns. A urinary catheter may be necessary to measure the urine output and assess the renal function and fluid balance, but it does not address the most urgent problem of the client.
Choice D Reason: This choice is correct because inspecting the mouth for signs of inhalation injuries is the priority action for a client who has sustained partial-thickness burns. Inhalation injuries are caused by inhaling hot air, smoke, or toxic gases that damage the airway and lungs. They can cause airway obstruction, bronchospasm, pulmonary edema, or respiratory failure. Therefore, the nurse should inspect the mouth for signs such as soot, singed nasal hairs, burns on the lips or tongue, hoarseness, stridor, or wheezes. The nurse should also monitor the oxygen saturation and arterial blood gases to assess the oxygenation and ventilation status of the client.
