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 ["3.4"]
Explanation
1 pound is approximately 0.453592 kilograms.
25 pounds * 0.453592 kg/pound = 11.3398 kg Calculate the total daily dosage:
15 mg/kg/12 hours * 11.3398 kg = 170.097 mg/12 hours
170.097 mg/12 hours * 2 doses/day = 340.194 mg/day Determine the amount of elixir needed per dose:
250 mg/5 mL = 50 mg/mL (strength of the elixir)
340.194 mg/day ÷ 2 doses/day = 170.097 mg/dose
170.097 mg/dose ÷ 50 mg/mL = 3.4 mL/dose
Correct Answer is B
Explanation
A. Long-acting beta2-adrenergic agonists (LABAs) are used for the maintenance treatment of asthma but are not suitable for immediate relief during an acute exacerbation. They take longer to take effect and are used as part of a long-term management plan rather than a rescue plan.
B. Short-acting beta2-adrenergic agonists (SABAs), such as albuterol, are the first-line treatment for acute asthma exacerbations. They work quickly to relax the muscles around the airways, providing immediate relief of bronchospasm and improving airflow. This is why they are referred to as "rescue" medications.
C. Mucolytics are used to thin and loosen mucus in the airways, which can be helpful for conditions involving thick mucus. However, they are not used for immediate relief of asthma symptoms and do not address bronchospasm directly. They are not appropriate as a first-line treatment in an acute asthma attack.
D. Inhaled corticosteroids are used for long-term control of asthma by reducing inflammation in the airways. While they are important for ongoing management, they do not provide immediate relief during an acute asthma exacerbation and should not be used as rescue medication.
