In a patient with chronic kidney disease, which of the following lab values would be expected?
- A. Elevated creatinine levels.
- B. Low hemoglobin levels.
- C. Elevated potassium levels.
- D. Low sodium levels.
Correct Answer: A
Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.

A client with cholelithiasis is admitted with jaundice due to obstruction of the common bile duct. Which finding is most important for the nurse to report to the healthcare provider?
- A. Distended, hard, and rigid abdomen
- B. Clay-colored stool
- C. Radiating sharp pain in the right shoulder
- D. Bile-stained emesis
Correct Answer: A
Rationale: The most important finding for the nurse to report to the healthcare provider in a client with cholelithiasis and jaundice due to common bile duct obstruction is a distended, hard, and rigid abdomen. These signs may indicate a possible surgical emergency, such as a complication like gallbladder perforation or peritonitis, which require immediate intervention. Clay-colored stool is associated with obstructive jaundice but does not indicate an acute surgical emergency. Radiating sharp pain in the right shoulder (referred pain from the diaphragm) and bile-stained emesis may also be seen in cholelithiasis but are not as urgent as a distended, hard, and rigid abdomen.
Angiotensin-converting enzyme (ACE) inhibitors may be prescribed for the client with diabetes mellitus to reduce vascular changes and possibly prevent or delay the development of:
- A. Chronic obstructive pulmonary disease (COPD).
- B. Pancreatic cancer.
- C. Renal failure.
- D. Cerebrovascular accident.
Correct Answer: C
Rationale: The correct answer is C: Renal failure. ACE inhibitors are commonly used in clients with diabetes mellitus to help reduce the progression of diabetic nephropathy by improving renal blood flow. This medication class can help prevent or delay the development of renal failure in these clients. Choices A, B, and D are incorrect because ACE inhibitors do not have a direct impact on preventing or delaying the development of chronic obstructive pulmonary disease, pancreatic cancer, or cerebrovascular accidents in clients with diabetes mellitus.
A client has driven himself to the emergency department. He is 50 years old, has a history of hypertension, and informs the nurse that his father died from a heart attack at age 60. The client has indigestion. The nurse connects him to an electrocardiogram monitor and begins administering oxygen at 2 L/min via nasal cannula. What should the nurse do next?
- A. Call for the physician.
- B. Start an IV infusion.
- C. Obtain a portable chest radiograph.
- D. Draw blood for laboratory studies.
Correct Answer: B
Rationale: In a client presenting with possible myocardial infarction who is receiving oxygen therapy and cardiac monitoring, the next priority action is to establish IV access by starting an IV infusion. This allows for prompt administration of medications and fluids as needed in the management of acute coronary syndromes. Calling the physician (Choice A) may be necessary but is not the immediate next step. Obtaining a portable chest radiograph (Choice C) may help in further assessment but is not as crucial as establishing IV access. Drawing blood for laboratory studies (Choice D) is important for diagnostic purposes but is not as urgent compared to starting an IV infusion in the setting of a potential myocardial infarction.
A client with a history of peptic ulcer disease (PUD) is admitted after vomiting bright red blood several times over the course of 2 hours. In reviewing the laboratory results, the nurse finds the client's hemoglobin is 12 g/dL (120g/L) and the hematocrit is 35% (0.35). Which action should the nurse prepare to take?
- A. Continue monitoring for blood loss
- B. Administer 1,000 mL (1L) of normal saline
- C. Transfuse 2 units of platelets
- D. Prepare the client for emergency surgery
Correct Answer: D
Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.
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.
