The healthcare provider is assessing a client with chronic renal failure who is receiving hemodialysis. Which of the following findings would indicate a complication of the treatment?
- A. Temperature of 98.6°F (37°C).
- B. Weight gain of 2 lbs (0.9 kg) since the last treatment.
- C. Blood pressure of 130/80 mm Hg.
- D. Pulse rate of 72 bpm.
Correct Answer: B
Rationale: Weight gain between dialysis sessions can indicate fluid overload, a common complication in clients with chronic renal failure. This can lead to complications such as hypertension, pulmonary edema, and heart failure. A normal temperature, blood pressure, and pulse rate are expected findings in this scenario and would not typically indicate a complication of hemodialysis treatment.

The nurse explains to the client with Hodgkin's disease that a bone marrow biopsy will be taken after the aspiration. What should the nurse explain about the biopsy?
- A. The biopsy will confirm the diagnosis of Hodgkin's disease.
- B. The biopsy will show the extent of the disease in the bones.
- C. The biopsy will be done to check for infection in the bones.
- D. The biopsy will help determine the best treatment for the disease.
Correct Answer: D
Rationale: A bone marrow biopsy helps determine the best treatment plan for Hodgkin's disease by providing crucial information about the extent and nature of the disease. While confirming the diagnosis is important, the primary purpose of the biopsy in this case is to guide treatment decisions. The biopsy is not primarily for assessing the extent of the disease in the bones or checking for infections in the bones.
After three days of persistent epigastric pain, a female client presents to the clinic. She has been taking oral antacids without relief. Her vital signs are heart rate 122 beats/minute, respirations 16 breaths/minute, oxygen saturation 96%, and blood pressure 116/70. The nurse obtains a 12-lead electrocardiogram (ECG). Which assessment finding is most critical?
- A. Irregular pulse rhythm
- B. Bile-colored emesis
- C. ST elevation in three leads
- D. Complaint of radiating jaw pain
Correct Answer: C
Rationale: ST elevation in three leads is a critical finding that suggests myocardial infarction, requiring immediate attention. This finding indicates ischemia or injury to the heart muscle. Choices A, B, and D are not as critical in this scenario. Irregular pulse rhythm may be concerning but does not indicate an immediate life-threatening condition like myocardial infarction. Bile-colored emesis and complaint of radiating jaw pain are relevant but not as indicative of a myocardial infarction as ST elevation in three leads.
In a patient with diabetes mellitus, which of the following is a sign of hypoglycemia?
- A. Polydipsia.
- B. Polyuria.
- C. Sweating.
- D. Dry skin.
Correct Answer: C
Rationale: Sweating is a common sign of hypoglycemia in diabetic patients. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can cause sweating as a response to the perceived danger. Polydipsia (excessive thirst) and polyuria (excessive urination) are actually more commonly associated with hyperglycemia, not hypoglycemia. Dry skin is not typically a sign of hypoglycemia.
In a patient with chronic kidney disease, which of the following is a common electrolyte imbalance?
- A. Hyperkalemia.
- B. Hypokalemia.
- C. Hypernatremia.
- D. Hyponatremia.
Correct Answer: A
Rationale: Hyperkalemia is a common electrolyte imbalance in chronic kidney disease. In chronic kidney disease, the kidneys' reduced function leads to the decreased excretion of potassium, resulting in elevated serum potassium levels. This can be dangerous as hyperkalemia can lead to life-threatening arrhythmias. Hypokalemia (Choice B) is less common in chronic kidney disease as the impaired kidneys tend to retain potassium. Hypernatremia (Choice C) is more commonly seen in conditions such as dehydration, not primarily in chronic kidney disease. Hyponatremia (Choice D) is also possible in chronic kidney disease but is less common compared to hyperkalemia.
The healthcare provider assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?
- A. Hyperaldosteronism causing increased sodium transport ion in renal tubules
- B. Decreased portacaval pressure with greater collateral circulation
- C. Decreased renin-angiotensin response related to increased renal blood flow
- D. Hypoalbuminemia that results in decreased colloidal oncotic pressure
Correct Answer: D
Rationale: In clients with cirrhosis, hypoalbuminemia leads to decreased colloidal oncotic pressure. This reduction in oncotic pressure contributes to the development of edema in the feet and legs (pitting edema) and ascites in the abdomen. Hyperaldosteronism (choice A) would lead to sodium retention but is not the primary mechanism behind edema and ascites in cirrhosis. Decreased portacaval pressure with greater collateral circulation (choice B) is not directly related to the pathophysiology of edema and ascites in cirrhosis. Decreased renin-angiotensin response related to increased renal blood flow (choice C) does not play a significant role in the development of edema and ascites in cirrhosis compared to the impact of hypoalbuminemia on colloidal oncotic pressure.
