Which of the following lab tests is NOT commonly ordered to ascertain whether the patient is experiencing large amounts of inflammation?

PT/INR

C-reactive protein (CRP)

Erythrocyte sedimentation rate (ESR)

Procalcitonin (PCT)

Answer and Explanation

The Correct Answer is A

A.   PT (Prothrombin Time) and INR (International Normalized Ratio) are tests primarily used to evaluate blood coagulation and the effectiveness of anticoagulant therapy. While they can provide some insight into a patient's overall health, they are not specific indicators of inflammation.
B.   CRP is a protein produced by the liver in response to inflammation. It is a well-established marker for detecting acute inflammation and is commonly used in clinical settings to assess inflammatory conditions.
C.   ESR measures how quickly red blood cells settle at the bottom of a test tube. An elevated ESR is a classic indicator of inflammation in the body and is commonly used in diagnosing various inflammatory conditions.
D.   Procalcitonin is a biomarker that can indicate bacterial infections and systemic inflammation. It is increasingly used in clinical practice to assess the severity of infection and inflammation, particularly in cases of sepsis.

Correct Answer is ["A","C","D"]

Explanation

A. Trauma can cause an elevated WBC count as part of the body’s response to injury. The immune system reacts to tissue damage by increasing WBC production to facilitate healing and fight potential infections.
B. Hyperglycemia itself does not directly cause an elevated WBC count. However, it may be associated with conditions like diabetes, where infections are more common. Therefore, while hyperglycemia can occur concurrently with elevated WBC counts, it is not a direct cause of the increase.
C. Infection is one of the most common causes of an elevated WBC count. The body responds to infections (bacterial, viral, etc.) by increasing WBC production to help combat the invading pathogens.
D. Inflammation, whether due to autoimmune conditions, allergies, or other causes, can also lead to an increase in WBC count. The inflammatory process triggers the immune response, resulting in elevated levels of white blood cells.
E. While steroid injections can influence WBC counts, they often cause a redistribution of white blood cells rather than an increase in production. Corticosteroids can cause a decrease in certain types of white blood cells (like lymphocytes) but may increase neutrophils due to a release from the bone marrow.

A. Call the MD to report a potential Emergency B. Call the MD to request a X-ray of the shoulder C. Perform a head to toe assessment and then chart your findings D. Call the MD to request an increase to their opioid dosage

Correct Answer is A

Explanation

A. A sudden new pain in a patient with SCD can be a sign of a serious complication, such as acute chest syndrome or stroke. Prompt medical evaluation is crucial to identify and address any underlying complications.
B. While an X-ray may be helpful to rule out other causes of shoulder pain, it is not the most urgent priority in this case. The patient's sudden onset of pain could be a sign of a serious complication that requires immediate attention.
C. While a head-to-toe assessment is important for any patient, it is not the most urgent priority in this case. The patient's new pain could be a sign of a serious complication that requires immediate medical attention.
D. Increasing the opioid dosage may provide temporary relief from the pain, but it does not address the underlying cause of the new pain.
