Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is caring for a client who has heart failure and is receiving a continuous IV infusion of furosemide. Which of the following findings indicates the nurse should increase the client's infusion rate?

• A. Urine output of 20 mL/hr
• B. Heart rate of 90/min
• C. Sodium level of 138 mEq/L
• D. Weight gain of 1 kg in 24 hr

Correct answer: D

Rationale: A weight gain of 1 kg in 24 hours can indicate fluid retention and worsening heart failure, requiring an increase in diuresis. This finding suggests that the current diuretic therapy is not effective enough to manage the fluid overload, necessitating an increase in the infusion rate of furosemide. Choices A, B, and C are not directly related to the need for an increase in diuretic therapy in heart failure patients. Urine output of 20 mL/hr, a heart rate of 90/min, and a sodium level of 138 mEq/L are important parameters to monitor but do not specifically indicate the need to increase the infusion rate of furosemide.

3. A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. The client weighs 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.

4. A client has a new prescription for metoprolol. Which of the following client statements indicates an understanding of the teaching?

• A. I will take this medication with a glass of milk.
• B. I will take my pulse before taking this medication.
• C. I will stop taking this medication if I experience nausea.
• D. I will take an antacid with this medication.

Correct answer: B

Rationale: The correct answer is B. Clients taking metoprolol should regularly check their pulse and should not take the medication if their pulse is too low. Option A is incorrect because metoprolol should not be taken with a glass of milk. Option C is incorrect because stopping medication abruptly can be harmful. Option D is incorrect because antacids should not be taken with metoprolol as they can decrease its absorption.

5. A nurse is assessing a client who has a chest tube. Which of the following findings should the nurse report to the provider?

• A. Constant bubbling in the water seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. Tidaling in the water seal chamber.
• D. Drainage of 75 mL in the first 24 hours.

Correct answer: A

Rationale: The correct answer is A: Constant bubbling in the water seal chamber. Constant bubbling in the water seal chamber can indicate an air leak, which compromises the integrity of the chest tube system and should be reported to the provider for immediate intervention. Choices B, C, and D are incorrect. Intermittent bubbling in the suction control chamber is an expected finding indicating that the system is working appropriately. Tidaling in the water seal chamber is a normal fluctuation of fluid level with inspiration and expiration, indicating that the system is functioning correctly. Drainage of 75 mL in the first 24 hours is within the expected range for chest tube drainage and does not require immediate reporting unless accompanied by other concerning symptoms.
