A nurse is reviewing a client's laboratory report of arterial blood gas (ABG) findings: pH 7.28, HCO3 18, and PaCO2 36. Which of the following conditions should the nurse anticipate when interpreting these findings?

Choice A reason:Lower extremity edema is more commonly associated with right-sided heart failure, as it indicates systemic fluid congestion.

Choice B reason:Crackles in lung bases are expected in left-sided heart failure due to pulmonary congestion from fluid backing up into the lungs².

Choice C reason:Jugular vein distention is typically a sign of right-sided heart failure, reflecting increased central venous pressure.

Choice D reason:Ascites, the accumulation of fluid in the peritoneal cavity, is generally associated with right-sided heart failure or liver disease, not specifically left-sided heart failure.

Choice A reason: Bradycardia, which is a slower than normal heart rate, is not a common finding associated with renal calculi. Renal calculi, or kidney stones, typically cause symptoms related to the urinary system rather than directly affecting the heart rate.

Choice B reason: Bradypnea, or abnormally slow breathing, is also not a typical symptom of renal calculi. Patients with kidney stones may experience changes in urination patterns, such as frequency or urgency, but not typically changes in respiratory rate.

Choice C reason: Severe pain is indeed the most common symptom associated with renal calculi. This pain, known as renal colic, is often sudden in onset, very severe, and may radiate from the back down to the lower abdomen or groin. The pain is caused by the stone moving into the ureter and causing a blockage, which leads to increased pressure and stretching of the kidney or ureter. Renal calculi can cause a range of symptoms, with severe pain being the most prominent and often the first symptom that leads individuals to seek medical care. The pain is typically very intense and can be accompanied by other symptoms such as nausea, vomiting, and hematuria (blood in the urine).

Choice D reason: Nocturia, or frequent urination at night, can be a symptom of renal calculi, especially if the stones affect the bladder or cause urinary tract infections. However, the most characteristic symptom of renal calculi is severe pain, not necessarily nocturia.
