A nurse is preparing to administer 40 mg of furosemide IV. Available is furosemide 10 mg/mL. How many mL should the nurse administer per dose?
The Correct Answer is ["4"]
Step 1: Determine the dosage required. Required dosage = 40 mg
Step 2: Determine the concentration of the available solution. Available concentration = 10 mg/mL
Step 3: Calculate the volume to be administered. Volume to be administered = Required dosage ÷ Available concentration Volume to be administered = 40 mg ÷ 10 mg/mL
Step 4: Perform the division. 40 ÷ 10 = 4
= The nurse should administer 4 mL.

Correct Answer is C
Explanation
Choice A reason: Ulnar Deviation
Ulnar deviation, or the bending of the fingers towards the ulna (the outer bone of the forearm), is more commonly associated with rheumatoid arthritis rather than osteoarthritis. Rheumatoid arthritis typically affects the joints symmetrically and can lead to deformities such as ulnar deviation due to chronic inflammation.
Choice B reason: Symmetric Joints Affected
Symmetric joint involvement is characteristic of rheumatoid arthritis, not osteoarthritis. Osteoarthritis usually affects joints asymmetrically, meaning it can affect one joint more than the other. It commonly affects weight-bearing joints such as the knees, hips, and spine.
Choice C reason: Pain Worsens with Activity
Pain that worsens with activity is a hallmark symptom of osteoarthritis. This condition is caused by the breakdown of cartilage in the joints, leading to pain and stiffness, especially after physical activity. The pain typically improves with rest but can become more persistent as the disease progresses.
Choice D reason: Weight Loss
Weight loss is not a typical manifestation of osteoarthritis. In fact, being overweight or obese is a risk factor for developing osteoarthritis, particularly in weight-bearing joints. Weight management is often recommended to help reduce the stress on affected joints and alleviate symptoms.
Correct Answer is B
Explanation
Choice A reason:
Draw sheet: A draw sheet can be used to assist in repositioning a patient, but it is not the most effective method for turning a client who has undergone spinal fusion. The primary concern is to maintain spinal alignment, which is best achieved through the log roll technique.
Choice B reason:
Log roll: The log roll technique is the preferred method for turning patients who have had spinal surgery. This technique involves moving the patient as a single unit, keeping the spine in alignment to prevent any twisting or bending that could disrupt the surgical site. It is especially important for obese patients to ensure that the spine remains stable during movement.
Choice C reason:
Sliding board: A sliding board is typically used to assist with transfers from one surface to another, such as from a bed to a wheelchair. It is not suitable for turning a patient in bed, particularly one who has had spinal surgery.
Choice D reason:
Hoyer lift: A Hoyer lift is a mechanical device used to lift and transfer patients who are unable to move themselves. While it can be useful for transferring patients, it is not designed for turning patients in bed and does not provide the necessary support to maintain spinal alignment during a turn.
