Which of the following conditions would be expected with a client with an elevated thyroid-stimulating hormone (TSH) level with a decreased Triiodothyronine (T3) and Thyroxine (T4) level?

Choice D rationale

Potassium is the electrolyte that can cause fatal cardiac dysrhythmias in a client with chronic kidney disease. Hyperkalemia, or high levels of potassium in the blood, is a common electrolyte disorder in patients with advanced chronic kidney disease. It can lead to dangerous cardiac arrhythmias and is considered a medical emergency.

Choice D rationale

Heartburn is a primary symptom of gastroesophageal reflux disease (GERD), which occurs when stomach acid frequently flows back into the esophagus, causing irritation and discomfort (nih.gov, n.d.).

Choice A rationale

Crohn's disease is a type of inflammatory bowel disease that can cause symptoms like abdominal pain, diarrhea, and weight loss, but heartburn is not a typical symptom (Healthline, 2022).

Choice B rationale

Diverticulitis results from inflammation or infection of diverticula in the colon, leading to symptoms like abdominal pain, fever, and changes in bowel habits (nih.gov, n.d.).

Choice C rationale

Ulcerative colitis is another type of inflammatory bowel disease that causes inflammation and ulcers in the colon, resulting in bloody diarrhea and abdominal pain, but not typically heartburn (Healthline, 2022).
