A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer?(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.).
0.4 mL.
0.6 mL.
0.8 mL.
1.0 mL.
The Correct Answer is B
Let's break down the calculation:
Given:
- Patient weight: 154 lbs
- Enoxaparin dosage: 0.75 mg/kg
- Available enoxaparin: 60 mg/0.6 mL
Step 1: Convert pounds to kilograms:
- 1 lb is approximately 0.4536 kg
- So, 154 lbs = 154 * 0.4536 kg/lb = 69.85 kg (approximately 70 kg)
Step 2: Calculate the total dose of enoxaparin:
- Desired dose = 0.75 mg/kg * 70 kg = 52.5 mg
Step 3: Determine the volume to administer:
- We have enoxaparin 60 mg/0.6 mL
- To find the volume for 52.5 mg:
- (52.5 mg / 60 mg) * 0.6 mL = 0.525 mL
- Rounded to the nearest tenth, this is 0.6 mL.
Therefore, the nurse should administer 0.6 mL of enoxaparin

Correct Answer is D
Explanation
Choice A rationale:
Severe headache can be a symptom of a subdural hematoma, but it is not the earliest manifestation of a change in neurological status. Other symptoms may appear before a severe headache, such as an altered level of consciousness.
Choice B rationale:
Bradycardia can occur with a subdural hematoma, especially as intracranial pressure increases. However, it is not the earliest manifestation of a change in neurological status. Changes in heart rate may occur later in the progression of the condition.
Choice C rationale:
Widened pulse pressure can also occur in patients with a subdural hematoma due to increased intracranial pressure. However, it is not the earliest manifestation of a change in neurological status. Other neurological signs would likely appear before changes in pulse pressure are evident.
Choice D rationale:
Change in level of consciousness is the earliest manifestation of a change in neurological status with a subdural hematoma. As intracranial pressure increases, the brain's functioning can be affected, leading to alterations in consciousness, ranging from mild confusion to unconsciousness.
Correct Answer is B
Explanation
Choice A rationale:
Administering furosemide may be appropriate for managing ascites, but it is not directly related to preventing complications. Furosemide is a diuretic that helps reduce fluid retention but does not address other potential complications of liver cirrhosis.
Choice B rationale:
Weighing the client weekly is essential to monitor changes in body weight and fluid status, which is crucial in detecting worsening ascites or fluid retention. Sudden weight gain could indicate an exacerbation of ascites or other complications, warranting timely intervention.
Choice C rationale:
Offering the client a high-sodium diet is contraindicated in managing ascites. A high-sodium diet would lead to increased fluid retention and worsen the ascites, potentially exacerbating the client's condition and increasing the risk of complications.
Choice D rationale:
Administering heparin is not relevant to preventing complications in a client with liver cirrhosis and abdominal ascites. Heparin is an anticoagulant, and its use is not indicated for this particular condition.
