Nursing Elites

1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

2. Which client will benefit most from the application of pneumatic compression devices to the lower extremities? The client who

• A. is immobile on prescribed bedrest.
• B. has pressure ulcers on several toes.
• C. has diminished pedal pulse volume.
• D. is confused and trying to climb out of bed.

Correct answer: A

Rationale: The correct answer is A. Pneumatic compression devices are most beneficial for immobile clients on prescribed bedrest to prevent deep vein thrombosis. Applying these devices helps in promoting circulation and preventing blood clots. Choices B, C, and D do not specifically relate to the primary indication for pneumatic compression devices, making them incorrect. Pressure ulcers, diminished pedal pulse volume, and confusion with climbing out of bed may require different interventions or treatments.

3. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?

• A. Endotracheal cuff pressure greater than 25 cm H2O.
• B. Decreased lung compliance during ventilation.
• C. Bilateral crackles with increased secretions.
• D. Restless client who is biting the endotracheal tube.

Correct answer: D

Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.

4. The nurse is caring for a client with chronic liver disease. Which lab value is most concerning?

• A. Elevated AST and ALT
• B. Decreased albumin level
• C. Elevated bilirubin level
• D. Prolonged PT/INR

Correct answer: D

Rationale: The correct answer is D, prolonged PT/INR. In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This indicates impaired liver function, leading to a higher risk of bleeding. Elevated AST and ALT (choice A) are indicators of liver damage but do not directly assess the risk of bleeding. Decreased albumin level (choice B) reflects impaired liver function but is not as directly related to bleeding risk as a prolonged PT/INR. Elevated bilirubin level (choice C) is a sign of liver dysfunction, specifically related to bile metabolism, and while important, it is not as directly associated with bleeding risk as a prolonged PT/INR in the context of chronic liver disease.

5. A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?

• A. Administer an epinephrine injection
• B. Call for immediate medical help
• C. Monitor airway, breathing, and circulation
• D. All of the above

Correct answer: A

Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.
