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.
0.5 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 0.5 mL.
Therefore, the nurse should administer 0.5 mL of enoxaparin

Correct Answer is B
Explanation
Choice A rationale:
An elevated WBC count (11,000/mm²) in a client starting treatment for MRSA infection may indicate an inflammatory response, but it is expected in this scenario, and the priority is not as high as other critical lab values.
Choice B rationale:
A serum pH of 7.25 indicates acidosis, which is a potentially life-threatening condition. In type 1 diabetes mellitus, diabetic ketoacidosis (DKA) is a common complication that can lead to metabolic acidosis. This lab result is a priority as it requires immediate attention.
Choice C rationale:
Hematocrit of 26% in a client with sickle cell disease might be low, but it is not the priority over the critically abnormal lab value of serum pH in option B.
Choice D rationale:
A urine specific gravity of 1.032 in a client diagnosed with dehydration is elevated, indicating concentrated urine due to dehydration. While dehydration is concerning, it is not as high-priority as the potentially life-threatening acidosis in option B.
Correct Answer is D
Explanation
Choice A rationale:
Is not suitable for a client who has undergone a mastectomy with axillary lymph node dissection. This exercise may put a strain on the surgical site and cause discomfort or injury.
Choice B rationale:
Is also not appropriate for a postoperative mastectomy client. It involves using the left hand extensively, which could potentially disrupt the healing process and cause pain.
Choice C rationale:
Is not recommended for a postoperative mastectomy client. It involves significant upper body movement, which may not be well-tolerated after surgery, especially with lymph node dissection.
Choice D rationale:
This exercise is suitable for a postoperative mastectomy client as it helps in maintaining hand and arm mobility without putting excessive strain on the surgical site. It also aids in preventing complications like lymphedema, which is a potential concern after lymph node dissection.
