What condition is terazosin used to treat?
Heart failure
Peripheral vascular disease
Pulmonary edema
Chronic hypertension
The Correct Answer is D
A. Heart failure: Terazosin is not primarily indicated for heart failure management. While it may have some vasodilatory effects that could theoretically reduce afterload, it is not a standard treatment for heart failure and does not address the core pathophysiology.
B. Peripheral vascular disease: Terazosin does not directly treat peripheral vascular disease. Its mechanism of action as an alpha-1 adrenergic blocker primarily targets vascular smooth muscle to lower systemic blood pressure rather than improve blood flow to peripheral tissues.
C. Pulmonary edema: Pulmonary edema is usually managed with diuretics, oxygen therapy, and addressing the underlying cause. Terazosin does not have an acute role in managing fluid overload or pulmonary congestion.
D. Chronic hypertension: Terazosin is an alpha-1 adrenergic blocker used to treat chronic hypertension by relaxing vascular smooth muscle, reducing peripheral vascular resistance, and lowering blood pressure. It is commonly prescribed for long-term blood pressure control, especially in clients who may also have benign prostatic hyperplasia.

Correct Answer is A
Explanation
A. Clarify the order with the healthcare provider: The order for digoxin 25 mg IV is dangerously high and far exceeds the usual therapeutic dose (typically micrograms, not milligrams). The nurse must verify the order before administration to prevent life-threatening toxicity.
B. Listen to the apical pulse for one minute: While assessing the apical pulse is essential before administering digoxin to check for bradycardia, verifying the unusually high dose takes priority to ensure client safety.
C. Obtain a current blood pressure reading: Monitoring blood pressure is important because digoxin can affect cardiac output, but confirming the safety of the ordered dose comes before vital sign assessment in this scenario.
D. Ensure the client's IV site is patent: Ensuring IV patency is necessary for safe medication administration, but it is secondary to clarifying an unsafe order to prevent immediate harm to the client.
Correct Answer is B
Explanation
A. Sulfa allergy: Inhaled corticosteroids are not sulfonamide-based medications, so a history of sulfa allergy does not increase the risk of adverse effects. Monitoring for allergic reactions related to sulfa is not necessary.
B. Diabetes mellitus: Inhaled corticosteroids can increase blood glucose levels by promoting gluconeogenesis and reducing insulin sensitivity. Clients with diabetes are at risk for hyperglycemia, so closer monitoring of blood glucose is essential while on this medication.
C. Asthma: Asthma is an indication for inhaled corticosteroids rather than a risk factor for adverse effects. While monitoring for effectiveness is important, asthma itself does not necessitate additional safety monitoring beyond standard care.
D. Cataracts: Long-term systemic corticosteroid use is associated with an increased risk of cataracts, but inhaled corticosteroids have a much lower systemic absorption. While eye exams may be part of long-term care, immediate close monitoring is not typically required for cataracts.
