Nursing Elites

1. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

2. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

3. Prior to surgery, written consent must be obtained. What is the nurse's legal responsibility with regard to obtaining written consent?

• A. Witness the consent and sign the form as a witness
• B. Inform the client of alternatives to the procedure
• C. Explain the procedure in detail to the client
• D. Determine that the surgical consent form has been signed and is included in the client's record

Correct answer: D

Rationale: The nurse's legal responsibility is to ensure that informed consent has been obtained by verifying that the client has signed the form and that it is included in the record. Witnessing the consent and signing as a witness is not the nurse's role, as this is typically done by a neutral party. Informing the client of alternatives to the procedure and explaining the procedure in detail are responsibilities of the healthcare provider performing the surgery, not the nurse.

4. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

5. An older adult client with heart failure (HF) and hypertension (HTN) is receiving atenolol, furosemide, and enalapril. Which assessments are essential to evaluate the effectiveness of the medications?

• A. Bowel sounds and daily weight.
• B. Daily weight and blood pressure.
• C. Heart sounds and range of motion.
• D. Monitor for evidence of hypokalemia.

Correct answer: B

Rationale: Monitoring daily weight and blood pressure is crucial to assess the effectiveness of diuretics (furosemide) and antihypertensives (atenolol, enalapril) in managing heart failure and hypertension. Changes in weight indicate fluid status, while blood pressure readings reflect the control of hypertension. Assessing bowel sounds and range of motion are important but not directly related to evaluating the effectiveness of these specific medications in this scenario. Monitoring for hypokalemia is important due to furosemide's potential side effect, but it is not the primary assessment to evaluate medication effectiveness.
