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 D
Explanation
A. Lethargy: Lethargy is not typically associated with overuse of albuterol. Albuterol is a beta-2 agonist that primarily stimulates the sympathetic nervous system, which usually increases alertness rather than causing sedation.
B. Weight gain: Weight gain is not a known side effect of albuterol overuse. Albuterol’s effects are more acute and related to cardiovascular and respiratory systems rather than fluid retention or metabolic changes that cause weight gain.
C. Hypotension: Albuterol can cause mild vasodilation, but hypotension is not a common clinical finding with overuse. Instead, sympathetic stimulation often leads to increased heart rate and blood pressure fluctuations rather than consistent low blood pressure.
D. Tachycardia: Overuse of albuterol can lead to tachycardia because it stimulates beta-1 receptors in the heart along with beta-2 receptors in the lungs. Frequent use may indicate poor asthma control and can manifest as palpitations, elevated heart rate, and potential arrhythmias.
Correct Answer is D
Explanation
A. Salivation: Diphenhydramine, an antihistamine with anticholinergic properties, typically reduces salivation rather than increases it. Excessive drooling is not a side effect of this medication.
B. Watery eyes: Diphenhydramine works to relieve allergic symptoms, including watery eyes, so this symptom is more likely to be a reason for taking the medication rather than a side effect.
C. Urinary frequency: Anticholinergic effects of diphenhydramine usually cause urinary retention, not increased frequency. Clients may experience difficulty voiding rather than needing to urinate more often.
D. Constipation: The anticholinergic action of diphenhydramine can slow gastrointestinal motility, leading to constipation. Clients should be advised about this potential side effect and strategies to prevent it, such as increased fluid and fiber intake.
