Nursing Elites

1. A nurse is reviewing laboratory results for a client who has chronic kidney disease. Which of the following findings should the nurse expect?

• A. Hypernatremia
• B. Hypocalcemia
• C. Low potassium
• D. Low magnesium

Correct answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

2. A nurse is caring for a client receiving a dopamine infusion via a peripheral IV. Which of the following actions should the nurse take if the IV site appears infiltrated?

• A. Stop the infusion.
• B. Slow the infusion.
• C. Apply a warm compress to the site.
• D. Apply a cold compress to the site.

Correct answer: A

Rationale: Corrected Rationale: If infiltration is suspected, the nurse should immediately stop the dopamine infusion to prevent further damage to the surrounding tissue. Choice A is the correct answer because continuing the infusion can lead to tissue damage and compromise the client's care. Slowing the infusion (Choice B) is not sufficient to prevent harm and may still cause damage. Applying a warm compress (Choice C) or a cold compress (Choice D) is not the recommended action for infiltration; stopping the infusion is crucial to prevent complications.

3. A healthcare professional is assessing a client in the PACU. Which finding indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: The correct answer is B: Oliguria. Oliguria (low urine output) is a sign of decreased cardiac output because the kidneys are not receiving enough blood to produce an adequate amount of urine. Shivering (choice A) is a response to hypothermia or the body's attempt to generate heat. Bradypnea (choice C) refers to abnormally slow breathing rate and is not directly related to cardiac output. Constricted pupils (choice D) are more indicative of conditions affecting the nervous system or medications.

4. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

5. A nurse is assisting with mass casualty triage following an explosion at a local factory. Which of the following clients should the nurse identify as the priority?

• A. A client who has massive head trauma
• B. A client who has full-thickness burns to the face and trunk
• C. A client with indications of hypovolemic shock
• D. A client with an open fracture of the lower extremity

Correct answer: C

Rationale: In a mass casualty situation, the nurse should prioritize the client with indications of hypovolemic shock. Hypovolemic shock is an immediate life-threatening condition resulting from severe blood loss, which can lead to organ failure and death. Prompt identification and treatment of hypovolemic shock are crucial to prevent further deterioration. While clients with massive head trauma, full-thickness burns, and open fractures require urgent care, hypovolemic shock takes precedence due to its rapid progression to a critical state.
