Nursing Elites

1. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

• A. Hypercalcemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypocalcemia

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

2. When a client is suspected of having a stroke, what is the nurse's priority action?

• A. Administer tissue plasminogen activator (tPA).
• B. Perform a neurological assessment.
• C. Position the client in a supine position.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: The correct answer is to perform a neurological assessment. When a stroke is suspected, the priority action is to assess the client neurologically to determine the extent of brain injury and identify any immediate risks, such as impaired airway, speech deficits, or loss of motor function. This assessment helps in early recognition of signs that are essential for timely intervention and guides further treatment, such as administering tissue plasminogen activator (tPA), if appropriate. Positioning the client in a supine position or checking the blood glucose level can be important but not the priority when a stroke is suspected.

3. A client with type 1 diabetes is admitted to the emergency room with abdominal pain, polyuria, and confusion. What should the nurse implement first?

• A. Administer intravenous insulin.
• B. Start an intravenous fluid bolus.
• C. Obtain a blood glucose level.
• D. Administer an antiemetic.

Correct answer: B

Rationale: In this scenario, the nurse should first start an intravenous fluid bolus. This intervention is crucial in addressing severe dehydration associated with diabetic ketoacidosis, a life-threatening complication of type 1 diabetes. Administering intravenous insulin (Choice A) is important but should follow fluid resuscitation. Obtaining a blood glucose level (Choice C) is necessary but not as urgent as addressing the dehydration. Administering an antiemetic (Choice D) is not the priority in this situation.

4. When assessing an IV site used for fluid replacement and medication administration, the client complains of tenderness when the arm is touched above the site. Which additional assessment finding warrants immediate intervention by the nurse?

• A. Cool skin at the IV insertion site
• B. Presence of fluid leaking around the IV catheter
• C. Swelling above the IV site
• D. Red streaks tracking the vein

Correct answer: D

Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.

5. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.
