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 C
Explanation
Choice A reason: Myocardial infarction (MI) is not limited to occurrences with exertion. While stable angina typically occurs during physical activity or emotional stress, MI can happen at any time, even at rest. The underlying cause of an MI is the complete blockage of blood supply to a part of the heart muscle, usually due to a blood clot in a coronary artery. This blockage can lead to the death of heart muscle tissue, a condition that requires immediate medical attention.
Choice B reason: Stable angina does not typically last for more than 30 minutes. It is characterized by chest pain or discomfort that occurs predictably with exertion or emotional stress and is relieved within minutes by rest or nitroglycerin. In contrast, the pain from an MI is more prolonged and severe, and it is not relieved by rest or nitroglycerin. If chest discomfort lasts longer than 15 minutes and is not alleviated by rest or nitroglycerin, it is a warning sign that the individual may be experiencing an MI.
Choice C reason: This is the distinguishing feature between stable angina and an MI. Stable angina is usually relieved within 3-5 minutes by rest or nitroglycerin, which helps to dilate the coronary arteries and improve blood flow to the heart muscle. Nitroglycerin is ineffective in relieving the symptoms of an MI because the problem is not just reduced blood flow but a complete blockage that nitroglycerin cannot overcome.
Choice D reason: The pain associated with an MI typically lasts for more than 15 minutes and can be quite severe. Unlike stable angina, the pain of an MI is not relieved by rest or nitroglycerin. The duration and severity of the pain, along with other symptoms such as shortness of breath, sweating, nausea, or lightheadedness, help differentiate an MI from stable angina.
Correct Answer is A
Explanation
Choice A reason:Pain that is relieved by food intake is a classic symptom of duodenal ulcers, as eating can neutralize stomach acid temporarily, providing relief.
Choice B reason:Pain radiating down the right arm is not a typical symptom of a duodenal ulcer; it is more commonly associated with cardiac issues.
Choice C reason:Nausea and vomiting can be associated with duodenal ulcers, but they are not as specific as pain relief by food intake.
Choice D reason:Weight loss can occur with duodenal ulcers due to pain and eating avoidance, but the key symptom that relates directly to the ulcer is pain relief after food intake.
