A nurse is assessing a client who has a sliding hiatal hernia.
Which of the following findings should the nurse expect?

Choice A rationale

Carbonated beverages contain gas that expands the stomach, increasing pressure on the lower esophageal sphincter (LES). This increased pressure can cause the LES to relax and allow gastric contents to reflux into the esophagus, exacerbating heartburn. Additionally, the acidic nature of many carbonated drinks can irritate the already inflamed esophageal lining.

Choice B rationale

Hot herbal tea can relax the esophageal muscles and soothe irritation. However, some herbal teas, like peppermint, can relax the lower esophageal sphincter, potentially worsening reflux. In contrast, chamomile or ginger tea may have a calming effect on the stomach and reduce inflammation, which can alleviate the symptoms of heartburn.

Choice C rationale

High-fat snacks, especially those consumed at bedtime, delay gastric emptying. The presence of food in the stomach for a prolonged period increases the risk of gastric reflux. Delayed emptying leads to a larger volume of stomach contents exerting pressure on the lower esophageal sphincter, making it more likely to open and allow acid to escape.

Choice D rationale

Lying down after meals increases the pressure on the lower esophageal sphincter and places the stomach contents in a position where gravity no longer helps keep them down. This postural change makes it easier for stomach acid to flow back into the esophagus, which is a primary cause of heartburn. Remaining upright for at least 30 minutes after eating is recommended. *.

Choice A rationale

Losartan is an angiotensin II receptor blocker (ARB) which works by preventing angiotensin II from binding to its receptors in vascular smooth muscle, thereby causing vasodilation and lowering blood pressure. Hypertension is the condition losartan is prescribed to treat, not an adverse effect, because its mechanism directly counteracts the vasoconstrictive effects of angiotensin II. The intended therapeutic effect is a reduction in systemic vascular resistance and blood pressure.

Choice B rationale

Double vision, also known as diplopia, is not a recognized common or significant adverse effect of losartan. The mechanism of action of losartan primarily targets the renin-angiotensin-aldosterone system (RAAS), influencing blood pressure regulation and fluid balance, not directly affecting the central nervous system or ocular motor function. This symptom would be more indicative of neurological or ophthalmological issues unrelated to the medication's primary action.

Choice C rationale

Dizziness is a common adverse effect of losartan. This is a direct consequence of its therapeutic action, which is to lower blood pressure. The resulting vasodilation and reduced blood pressure can lead to orthostatic hypotension, causing feelings of lightheadedness or dizziness, especially when a person changes positions, like standing up. The brain's reduced perfusion pressure triggers this sensation as a physiological response.

Choice D rationale

Hyperactivity is not an expected adverse effect of losartan. The medication primarily affects the cardiovascular system by modulating the RAAS to lower blood pressure. It does not have known stimulant properties that would lead to increased energy, restlessness, or hyperactivity. Such a finding would likely be attributed to other factors or a different underlying condition, not the pharmacological action of this medication. *.
