A nurse is teaching a client diagnosed with benign prostatic hyperplasia (BPH) about a new prescription for Flomax. Which side effects should the nurse include in the teaching?

Choice A reason: Flomax, a selective alpha-1 blocker, causes vasodilation by relaxing smooth muscles, which can lead to orthostatic hypotension and lightheadedness. This occurs due to decreased vascular resistance, particularly when standing, requiring patient education to change positions slowly to prevent falls and ensure safety during treatment. Choice B reason: Temporary loss of libido is a known side effect of Flomax, as alpha-1 blockers can affect sexual function by altering smooth muscle tone in the reproductive system. This may disrupt ejaculation or sexual desire, but effects are often reversible, necessitating patient education to manage expectations and adherence. Choice C reason: Hypertension is not a side effect of Flomax; instead, it causes hypotension by relaxing vascular smooth muscles. This reduces blood pressure, which is therapeutic for BPH but can lead to dizziness. Hypertension would be a contraindication, not an expected outcome of this medication. Choice D reason: Fungal infection is not associated with Flomax, which targets alpha-1 receptors to relieve BPH symptoms. Fungal infections may occur with antibiotics or immunosuppression but are unrelated to alpha-blockers, making this an incorrect side effect to include in patient teaching.
