A student nurse asks what "primary hypertension" is. What response by the registered nurse is best?
"It is hypertension with no specific cause."
"It means it is essential that it be treated."
"It means it is caused by another disease."
"It refers to severe and life-threatening hypertension.
The Correct Answer is A
A. Primary hypertension, also known as essential hypertension, is characterized by high blood pressure that does not have a known secondary cause. It accounts for the majority of hypertension cases and is thought to result from a combination of genetic, environmental, and lifestyle factors.
B. While treatment is important for all forms of hypertension to prevent complications, this statement is somewhat misleading. The term "essential" in primary hypertension refers to the lack of a specific identifiable cause, not that it is necessarily more critical to treat than other forms of hypertension.
C. This definition describes secondary hypertension, not primary hypertension. Secondary hypertension results from an identifiable underlying condition, such as kidney disease or hormonal disorders.
D. Primary hypertension can vary in severity, but it is not exclusively severe or life-threatening. While uncontrolled hypertension can lead to serious complications, primary hypertension itself does not automatically imply a critical state.

Correct Answer is D
Explanation
A. Auscultating breath sounds can provide valuable information about the presence of wheezing, crackles, or diminished breath sounds, which may indicate respiratory issues. However, while this assessment is important for understanding the underlying cause of dyspnea, it does not directly measure the patient's oxygenation status.
B. Observing chest expansion can help the nurse assess the mechanics of breathing and whether there are any restrictions in lung expansion. While this assessment is useful, it does not provide a clear indication of the patient's oxygen saturation levels or immediate need for supplemental oxygen.
C. Measuring capillary refill can give insights into peripheral perfusion and circulation, which can be affected by oxygenation. However, it is not the most direct or specific assessment for determining the need for supplemental oxygen in a patient with dyspnea.
D. Measuring oxygen saturation (using a pulse oximeter) provides a direct and objective assessment of the patient's oxygenation status. Normal oxygen saturation levels typically range from 95% to 100%. If the oxygen saturation is below the acceptable range (usually less than 92% in many clinical settings), this would indicate the need for supplemental oxygen.
Correct Answer is C
Explanation
A. ACE inhibitors can cause a dry cough in some patients, but this is not typically a severe issue for patients with asthma.
B. These medications do not have a significant impact on respiratory function and are generally safe for patients with asthma.
C. Beta-blockers can constrict the airways, making them less suitable for patients with asthma. They can worsen asthma symptoms, trigger bronchospasm, and reduce the effectiveness of beta-agonist bronchodilators.
D. Thiazide diuretics do not have a significant impact on respiratory function and are generally safe for patients with asthma.
