Which technique should the nurse use when assessing the client for early signs of rheumatoid arthritis?

Observe the skin for lesions.

Palpate the lymph nodes.

Palpate large joints for nodules.

Observe the client’s fingers.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Observing the skin for lesions is not a specific technique for assessing early signs of rheumatoid arthritis. While RA can sometimes manifest with skin lesions, they are not typically present in the early stages of the disease. Moreover, skin lesions can be indicative of a wide range of other conditions, making them a less reliable indicator of RA.

Choice B rationale:

Palpating the lymph nodes is also not a specific technique for assessing early signs of rheumatoid arthritis. Lymph node enlargement can occur in various inflammatory conditions, including infections and autoimmune diseases. It is not a characteristic feature of early RA.

Choice C rationale:

Palpating large joints for nodules is a technique used to assess for rheumatoid arthritis, but it is more likely to detect nodules in later stages of the disease. Nodules are typically firm, non-tender bumps that develop under the skin around joints. They are often found in areas like the elbows, knuckles, and fingers. However, they may not be present in the early stages of RA.

Choice D rationale:

Observing the client's fingers is the most appropriate technique for assessing early signs of rheumatoid arthritis. This is because the fingers are often the first joints to be affected by the disease. Early signs of RA in the fingers can include:

Swelling of the finger joints, particularly the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints. Tenderness and pain in the finger joints, especially upon movement.

Stiffness in the finger joints, which is often worse in the mornings and after periods of inactivity. Redness or warmth in the finger joints.

Difficulty bending or straightening the fingers.

Correct Answer is B

Explanation

Choice A rationale:

Hemoccult test on sputum collected from hemoptysis is not a diagnostic test for TB. It is a test for blood in the stool, which can be a symptom of TB but is not specific to TB.

Hemoptysis, or coughing up blood, can occur in various conditions, including bronchitis, pneumonia, lung cancer, and TB. The Hemoccult test cannot differentiate between these causes, making it an unreliable test for diagnosing TB.

Choice B rationale:

Sputum culture positive for Mycobacterium tuberculosis is the definitive diagnostic test for TB.

It involves collecting a sample of sputum, which is the mucus coughed up from the lungs, and culturing it in a laboratory to see if Mycobacterium tuberculosis, the bacteria that causes TB, grows.

This test is highly specific for TB, meaning that a positive result is almost always indicative of TB infection. It is also sensitive, meaning that it can detect TB infection even when there are few bacteria present.

Choice C rationale:

Positive purified protein derivative (PPD) skin test indicates exposure to TB but does not confirm active infection.

The PPD skin test involves injecting a small amount of tuberculin, a protein derived from Mycobacterium tuberculosis, into the skin.

If a person has been exposed to TB, their immune system will react to the tuberculin, causing a raised red bump to appear at the injection site.

However, a positive PPD skin test does not necessarily mean that a person has active TB infection.

It could also mean that they have been exposed to TB in the past but have successfully fought off the infection. Further testing, such as a sputum culture, is needed to confirm the diagnosis of TB.

Choice D rationale:

Chest X-ray or computed tomography (CT) can show abnormalities in the lungs that are suggestive of TB, but they cannot definitively diagnose TB.

These imaging tests can reveal changes in the lungs, such as nodules, inflammation, or fluid buildup, which can be caused by TB or other conditions.

Therefore, a chest X-ray or CT scan alone is not sufficient to diagnose TB. A sputum culture is still needed to confirm the diagnosis.

A. Measure oxygen saturation. B. Auscultate bowel sounds. C. Assess body temperature. D. Check serum creatinine.

Correct Answer is D

Explanation

Measuring oxygen saturation is not directly relevant to the administration of vancomycin or the monitoring of its potential side effects. While oxygen saturation is important to assess in patients with respiratory concerns, it does not provide information about kidney function, which is essential for safe vancomycin use.

Choice B rationale:

Auscultating bowel sounds, while a part of general abdominal assessment, is not the most crucial action before administering vancomycin. Vancomycin is not known to have significant effects on bowel motility, and its primary concern is nephrotoxicity.

Choice C rationale:

Assessing body temperature can be helpful in evaluating for infection, but it is not the most specific or sensitive indicator of vancomycin-related adverse effects. Fever can be a sign of various conditions, and it does not directly assess kidney function.

Choice D rationale:

Checking serum creatinine is the most essential action before administering vancomycin because it allows for assessment of kidney function. Vancomycin is primarily excreted by the kidneys, and impaired renal function can lead to elevated drug levels and increased risk of nephrotoxicity. By checking serum creatinine, the nurse can ensure that the patient's kidney function is adequate to safely excrete vancomycin and can adjust the dosage or frequency of administration if necessary.
