A student nurse is reviewing clinical manifestations of chronic kidney disease. Which of the following findings are consistent with this diagnosis? (Select all that apply)
Hypokalemia
Anemia
Hypertension
Crackles in the lungs
Lethargy
Proteinuria
Correct Answer : B,C,E,F
Choice A: Hypokalemia, or low potassium levels in the blood, is not typically associated with CKD. In fact, patients with advanced CKD are more likely to experience hyperkalemia, which is an elevated potassium level, due to the kidneys’ decreased ability to excrete potassium. The normal range for serum potassium is 3.5 to 5.0 mmol/L.
Choice B: Anemia is a common finding in CKD and is due to the kidneys’ reduced production of erythropoietin, a hormone that stimulates the bone marrow to produce red blood cells. Symptoms of anemia include fatigue, weakness, and pale skin. The normal range for hemoglobin in adults is 13.8 to 17.2 grams per deciliter for men and 12.1 to 15.1 grams per deciliter for women.
Choice C: Hypertension, or high blood pressure, is both a cause and a complication of CKD. The kidneys play a crucial role in regulating blood pressure, and as their function declines, hypertension becomes more common. The normal range for blood pressure is typically considered to be 120/80 mmHg.
Choice D: Crackles in the lungs Crackles in the lungs are not a direct manifestation of CKD, but they can occur if the condition leads to fluid overload and heart failure, resulting in pulmonary edema. This is a secondary complication rather than a direct symptom of CKD.
Choice E: Lethargy and a general feeling of malaise are common in CKD due to the buildup of toxins and waste products in the blood that the kidneys can no longer effectively filter out. This can also lead to decreased mental sharpness and a reduced quality of life.
Choice F: Proteinuria, or the presence of excess protein in the urine, is a hallmark sign of CKD. It indicates damage to the kidneys’ filtering units, allowing protein that would normally be retained to leak into the urine. Persistent proteinuria is a sign of chronic kidney damage.

Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A reason: Pain occurring 30 to 60 minutes after a meal is a common symptom of gastric ulcers due to the increased gastric acid secretion during digestion that can aggravate the ulcer.
Choice B reason: Pain at night is also typical for gastric ulcers as the circadian rhythm can influence acid secretion, potentially leading to increased discomfort during the night.
Choice C reason: A sensation of bloating can be associated with gastric ulcers due to delayed gastric emptying or increased sensitivity of the stomach lining.
Choice D reason:Pain relieved by eating is indicative of gastric ulcers because food can act as a buffer to stomach acid, temporarily relieving pain².
Choice E reason:Pain upon palpation of the epigastric region is expected in clients with gastric ulcers due to the localized inflammation and sensitivity of the stomach lining².
Correct Answer is A
Explanation
Choice A: Troponin Troponin levels increase within 3-12 hours from the onset of chest pain, peak at 24-48 hours, and return to baseline over 5-14 days. Troponin is a protein found in cardiac muscle fibers that regulates muscular contraction. When heart muscle is damaged, as in the case of an MI, troponin is released into the bloodstream. The elevation of troponin levels is a key indicator of myocardial infarction and can be used to diagnose and assess the extent of heart muscle damage. Troponin is the most reliable laboratory value that is expected to be elevated following a myocardial infarction, making it the correct choice in this scenario.
Choice B: Aspartate aminotransferase (AST) AST is an enzyme found in high concentrations in the liver, heart, muscles, kidneys, and brain. It is released into the bloodstream when any of these tissues are damaged. While AST can be elevated in cases of MI, it is not as specific as troponin because it is present in many other tissues besides the heart.
Choice C: Serum amylase Serum amylase is an enzyme that helps digest carbohydrates and is primarily associated with the pancreas and salivary glands. Its elevation is not specifically related to myocardial infarction but can be seen in other conditions such as pancreatitis.
Choice D: Unconjugated bilirubin Unconjugated bilirubin is a breakdown product of hemoglobin from red blood cells. Elevated levels of unconjugated bilirubin are typically associated with conditions affecting the liver or the breakdown of red blood cells, not myocardial infarction.
