How would the nurse best evaluate the effectiveness of drug therapy for a client diagnosed with pneumonia being treated with amoxicillin?
Oral temperature of 100.6°F.
Pulse oximetry of 98% on room air.
Increased neutrophil count.
Adequate urine output.
The Correct Answer is B
Choice A Reason
An oral temperature of 100.6°F may indicate that the client still has a fever, which could suggest ongoing infection. However, temperature alone is not the most reliable indicator of the effectiveness of antibiotic therapy, as it can be influenced by various factors.
Choice B Reason
Pulse oximetry measures the oxygen saturation of the blood, which is a direct indicator of respiratory function. For a client with pneumonia, an improvement in oxygen saturation to 98% on room air is a strong sign that the lungs are effectively exchanging gases and that the pneumonia is resolving. This would be a clear indication that the amoxicillin is effective.
Choice C Reason
An increased neutrophil count is a sign of acute infection, but it does not directly measure the effectiveness of the antibiotic therapy. Neutrophil counts can remain elevated even as the infection is resolving, so they are not the best sole indicator of therapeutic effectiveness.
Choice D Reason
Adequate urine output is important for overall health and indicates good kidney function, but it is not a direct measure of the effectiveness of antibiotic therapy for pneumonia. Urine output does not reflect the respiratory status or the resolution of lung infection.

Correct Answer is D
Explanation
Choice A reason:
Ulnar deviation, which is the angling of the fingers towards the little finger side of the hand, is more commonly associated with rheumatoid arthritis, not osteoarthritis. Osteoarthritis typically affects the joint's cartilage, leading to pain and stiffness, rather than causing the fingers to deviate.
Choice B reason:
Symmetric joint involvement is also more characteristic of rheumatoid arthritis. Osteoarthritis usually affects joints asymmetrically, meaning it's more likely to affect one side of the body or one particular joint at a time.
Choice C reason:
Weight loss is not a direct manifestation of osteoarthritis. In fact, being overweight is a risk factor for developing osteoarthritis due to the increased stress on weight-bearing joints. However, weight management through diet and exercise can be part of the treatment plan for osteoarthritis to alleviate symptoms and improve joint function.
Choice D reason:
Joint stiffness and limited range of motion are hallmark manifestations of osteoarthritis. These symptoms result from the breakdown of cartilage within the joints, which leads to pain and difficulty moving the affected joint. Stiffness is often most noticeable upon waking or after periods of inactivity, and the range of motion may decrease as the condition progresses.
Correct Answer is D
Explanation
Choice A Reason
Performing a bladder scan can help determine the volume of urine in the bladder and assess for urinary retention, which could contribute to bladder spasms. However, this is not typically the first intervention. The priority is to ensure that the catheter is patent and draining correctly, as blockages can cause immediate discomfort and increased spasms
Choice B Reason
Stopping the irrigation could be considered if there is a concern that the CBI is contributing to the spasms. However, this would not be the first action taken. It is essential first to assess the catheter's patency and the flow of the irrigation to rule out any obstruction or kinking causing the spasms.
Choice C Reason
Administering an oral analgesic may help alleviate the discomfort caused by bladder spasms, but it does not address the underlying cause. Pain relief is important, but the initial step should be to check for and resolve any mechanical issues with the catheter system that could be causing the spasms.
Choice D Reason
Ensuring that the catheter is draining properly is the first and most crucial intervention. If the catheter is blocked or kinked, it can cause bladder distention and increased spasms. Checking the catheter's patency and the flow of irrigation can quickly resolve the issue and provide relief to the patient. If the catheter is found to be obstructed, resolving the blockage can decrease the severity of the spasms and improve the patient's comfort.
