A student nurse asks what "primary hypertension" is. What is the best response by the registered nurse?
"It is hypertension with no specific cause."
"It refers to severe and life-threatening hypertension."
"It means it is 'essential' that it be treated."
"It means it is caused by another disease."
The Correct Answer is A
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.

Correct Answer is C
Explanation
A. While yogurt is a nutritious food, it is not a significant source of iron.
B. Oranges are rich in vitamin C, which can help the body absorb iron from other foods. However, they are not a significant source of iron themselves.
C. Red meat, such as beef, lamb, and pork, is an excellent source of heme iron, which is easily absorbed by the body. This makes red meat a highly recommended food for people with iron deficiency.
D. Cashews are a good source of plant-based iron, but they also contain phytates, which can interfere with iron absorption. Therefore, while cashews can contribute to iron intake, they may not be as effective as red meat in addressing iron deficiency.
Correct Answer is C
Explanation
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.
