A Blood Pressure Drug That Raises Uric Acid: Reflecting on Antihypertensive Selection for a 56-Year-Old Man With Gout
This module's ShadowHealth exercise asked me to review a virtual patient's blood pressure regimen and propose changes. The patient, described here as a composite, is a 56-year-old delivery supervisor whose average office and home readings are 152/94 mm Hg on hydrochlorothiazide 25 mg daily, and who has had three gout flares in the past year. This essay reflects on my reasoning and answers the module's prompts on selection, monitoring, adverse effects, interactions, education, and lifestyle.
Reflection and Selection Rationale
I recognized the uncontrolled blood pressure quickly but did not link it to his gout until I reviewed his problem list a second time. Thiazide diuretics reduce the kidney's excretion of uric acid and raise serum urate, which can trigger flares. The 2020 gout guideline advises switching hydrochlorothiazide to another agent when feasible and choosing losartan preferentially, since losartan has a modest uricosuric effect not shared by other angiotensin receptor blockers (FitzGerald et al., 2020).
His readings are more than 20/10 mm Hg above the goal of below 130/80 mm Hg, so current guidance supports starting two first-line agents from different classes (Whelton et al., 2018). I would stop hydrochlorothiazide and start losartan 50 mg daily with amlodipine 5 mg daily. The choice treats his blood pressure and removes a cause of his gout at the same time.
Monitoring, Adverse Effects, and Interactions
I would check a basic metabolic panel two to four weeks after starting losartan to monitor potassium and creatinine, and see him monthly until his blood pressure reaches goal, with home readings in between. Losartan can cause hyperkalemia, dizziness, and rarely angioedema. Amlodipine commonly causes ankle swelling, which is dose-related. The most important interaction is with nonsteroidal anti-inflammatory drugs, which he may take for flares: they blunt the effect of both drugs and, combined with an angiotensin receptor blocker, can impair kidney function. Colchicine or a short course of prednisone may be safer flare options for him, and potassium supplements or salt substitutes should be avoided.
Education and Lifestyle
He should learn to measure his blood pressure correctly at home with a validated upper-arm cuff: seated with his back supported and feet flat, after five minutes of quiet rest, with the cuff at heart level, taking two readings a minute apart morning and evening for a week before each visit (Muntner et al., 2019). Lifestyle measures that lower both blood pressure and urate help him twice: the DASH eating pattern, reduced sodium, limiting alcohol, particularly beer, and weight loss if needed (Whelton et al., 2018). He should also know that ankle swelling or lightheadedness should be reported, not a reason to stop taking his medicine on his own.
What I Learned
This exercise showed me that a drug can be correct for the diagnosis and wrong for the patient. In future exams I will read the whole problem list before judging a regimen, because the best antihypertensive is often the one that helps, or at least does not harm, the patient's other conditions.

How this N 511 Module 3 example is structured
N511 Module 3 typically asks for a reflection essay of about 500 words in APA on your ShadowHealth assignment, with at least two scholarly sources, focused on antihypertensive medications: why you chose them, how you would monitor, adverse effects, interactions, education and lifestyle. Your exam is your own work and is not sampled. Aspen revises courses, so follow your classroom's prompt. This example reflects briefly, defends each drug with a guideline and answers each prompt for this patient.
N511 Module 3 questions, answered
What does N511 Module 3 usually ask for?
A reflection essay of about 500 words on your ShadowHealth assignment focused on antihypertensive therapy, with at least two scholarly sources, covering selection rationale, monitoring, adverse reactions, interactions, education and lifestyle changes.
Why switch from hydrochlorothiazide in a patient with gout?
Thiazides reduce uric acid excretion and raise serum urate, which can trigger flares. The 2020 ACR gout guideline advises switching to another agent when feasible and choosing losartan preferentially because of its mild uricosuric effect.
When should two blood pressure drugs be started together?
The 2017 ACC/AHA guideline supports starting two first-line agents from different classes when blood pressure is more than 20/10 mm Hg above the goal of below 130/80 mm Hg.
