A nurse is preparing to administer cefoxitin 80 mg/kg/day IV every 6 hr to a 6-year-old child who weighs 20 kg. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["400"]
To solve this problem, we need to apply the following formula:
Dose (mg) = Dose (mg/kg/day) x Weight (kg) / Frequency Plugging in the given values, we get:
Dose (mg) = 80 x 20 / 4 Dose (mg) = 400
Therefore, the nurse should administer 400 mg of cefoxitin per dose to the child.

Correct Answer is A
Explanation
A. Deep breathing is a relaxation technique that can help reduce pain by increasing oxygen delivery, decreasing muscle tension, and promoting a sense of calmness. The nurse should instruct the client to breathe slowly and deeply through the nose and exhale through the mouth.
B. Heat therapy may provide relief for muscle-related back pain but should not be applied for prolonged periods as it may cause tissue damage.
C. Minimizing environmental stimuli can help the client focus on relaxation techniques and alleviate pain perception but is not as effective as deep breathing.
D. Ice therapy is typically used for acute pain or inflammation and may not be appropriate for mild, ongoing back pain.
Correct Answer is D
Explanation
A. With the Z-track method, the skin is pulled laterally or to the side before the needle is inserted and released after the injection is administered to ensure the medication remains within the muscle and does not leak into the subcutaneous tissue.
B. The angle of insertion for intramuscular injections can vary depending on factors such as the client's body habitus and the length of the needle but is typically 90 degrees.
C. The needle should be withdrawn slowly and steadily to minimize tissue trauma and prevent medication leakage.
D. The Z-track method involves pulling the skin laterally or to the side before inserting the needle to create a zigzag pathway for the medication. This helps seal the needle track after the injection, reducing the risk of medication leakage into subcutaneous tissues.
