Which test would the nurse expect the primary care provider to order to look for exposure to tuberculosis?

A. Primary hypertension, also known as essential hypertension, is characterized by high blood pressure without an identifiable or specific medical cause. It is the most common type of hypertension, and its development is thought to result from a combination of genetic, environmental, and lifestyle factors.
B. This statement is misleading. While hypertension can be severe, primary hypertension is not defined by its severity or immediate life-threatening nature. Instead, primary hypertension can range from mild to severe, but the key characteristic is the absence of a specific underlying cause.
C. While treating hypertension is important, the term "essential" in primary hypertension refers to its lack of a known cause, not the urgency or necessity of treatment. This option could confuse the terminology as it does not accurately define the type of hypertension.
D. This statement describes secondary hypertension, which occurs as a result of another medical condition (e.g., kidney disease, hormonal disorders). Primary hypertension, in contrast, does not have a direct identifiable cause.

A. While this information is important for understanding the cause of the asthma exacerbation, it is not the most critical piece of information needed for immediate treatment.
B. Knowing when the symptoms began can help determine the severity of the exacerbation and the need for additional interventions. However, it is not as important as knowing the last dose of medication.
C. This information is crucial for determining the appropriate treatment. If the child has not received their regular medications as prescribed, they may need additional doses to manage the exacerbation.
D. Knowing the child's history of asthma exacerbations is important for assessing the severity of the current episode and planning long-term management. However, it is not the most critical piece of information needed for immediate treatment.
