A child weighing 55 lb has been prescribed cefotaxime at a dosage of 150 mg/kg/day, to be administered in divided doses every 6 hours.

How many mg should the nurse administer each day? (Provide a numerical value only.)

Choice A rationale

The patient is resting and cooperative, which indicates a calm and alert state, not agitation. Orientation x means the patient is aware of person, place, time, and situation, which is a normal finding. Dizziness is not mentioned in the patient’s condition. Pupils being equal and reactive to light is a normal finding and does not indicate a neurological issue.

Choice B rationale

Bradycardia refers to a slower than normal heart rate, which is not mentioned in the patient’s condition. Weak bilateral radial pulses could indicate poor blood circulation, but this is not mentioned in the patient’s condition. Capillary refill of 2 seconds is a normal finding. The absence of lower leg edema is a normal finding and does not indicate a cardiovascular issue.

Choice C rationale

Clear breath sounds are a normal finding and indicate that the patient’s lungs are free of obstructions or fluid.

Choice D rationale

The last reported bowel movement being 4 days ago could indicate constipation, but this is not mentioned in the patient’s condition.

Choice A rationale

Osteoarthritis is a joint disease in which the tissues in the joint, including the cartilage, break down over time. The degradation of joint cartilage is the primary pathological condition that leads to the symptoms of osteoarthritis, such as increased pain and stiffness.

Choice B rationale

A systemic inflammatory response is not the primary cause of osteoarthritis. While inflammation can occur in the affected joint, osteoarthritis is not a systemic inflammatory disease like rheumatoid arthritis.

Choice C rationale

An infectious process in the synovial fluid is not typically associated with osteoarthritis. Infections can lead to a different type of arthritis known as septic arthritis.

Choice D rationale

A decrease in bone mineral density is associated with osteoporosis, not osteoarthritis. In osteoarthritis, the issue is primarily with the degradation of cartilage, not a loss of bone density.
