Prepare for the NCLEX-RN® by learning the crucial next step in diagnosing Raynaud phenomenon after a comprehensive history and physical assessment. Find out which diagnostic test the nurse will prepare the client for and its significance in confirming the diagnosis. Get informed and stay prepared for your nursing journey.

The nurse has completed a history and physical for a client suspected of having Raynaud phenomenon. Which diagnostic test should the nurse prepare the client for next?

A. Angiography

B. Echocardiogram

C. Polymerase chain reaction (PCR) assay

D. Nailfold capillary microscopy

Scroll down for the correct answer!

The correct answer to today's NCLEX-RN® Question is...

D. Nailfold capillary microscopy

Rationale: Nailfold capillary microscopy can be performed to see whether finger capillaries are normal in appearance. If they are normal in appearance, this would be consistent with primary Raynaud phenomenon, and if they are damaged, it would be consistent with secondary Raynaud phenomenon.

Major Takeaway

The diagnosis of Raynaud phenomenon is usually based on history and physical assessment and the identification of a possible trigger or associated disease. In addition, nailfold capillary microscopy can be done to see whether finger capillaries are normal in appearance, which would be consistent with primary Raynaud phenomenon, or if they are damaged, which would be consistent with secondary Raynaud phenomenon. Regular monitoring for the development of autoimmune diseases is also recommended as there is an increased risk in the presence of Raynaud phenomenon.

Incorrect answer explanations

A. Angiography

Rationale: Angiography is not used to evaluate a client suspected of having Raynaud phenomenon. Angiography is an invasive test to assess the cardiovascular system for conditions like coronary artery atherosclerosis.

B. Echocardiogram

Rationale: An echocardiogram is not used to evaluate a client suspected of having Raynaud phenomenon. It is used to assess blood flow through the heart's structures.

C. Polymerase chain reaction (PCR) assay

Rationale: A PCR assay is not used to evaluate a client suspected of having Raynaud phenomenon. A PCR assay detects genetic material from infectious organisms, such as viruses.
