Nursing Elites

1. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

2. The nurse plans to administer a scheduled dose of metoprolol (Toprol SR) at 0900 to a client with hypertension. At 0800, the nurse notes that the client's telemetry pattern shows a second-degree heart block with a ventricular rate of 50. What action should the nurse take?

• A. Administer the Toprol immediately and monitor the client until the heart rate increases.
• B. Provide the dose of Toprol as scheduled and assign a UAP to monitor the client's BP q30 minutes.
• C. Give the Toprol as scheduled if the client's systolic blood pressure reading is greater than 180.
• D. Hold the scheduled dose of Toprol and notify the healthcare provider of the telemetry pattern.

Correct answer: D

Rationale: In clients with second-degree heart block, beta blockers such as metoprolol (Toprol SR) are contraindicated as they can further decrease the heart rate. Administering metoprolol in this situation can lead to serious complications. The correct action for the nurse to take is to hold the scheduled dose of Toprol and promptly notify the healthcare provider of the telemetry pattern. This ensures patient safety and appropriate management of the cardiac condition. Choices A, B, and C are incorrect because administering Toprol despite the heart block can worsen the condition and pose a risk to the client's health.

3. An adolescent's mother calls the clinic because the teen is having recurrent vomiting and has been combative in the last 2 days. The mother states that the teen takes vitamins, calcium, and magnesium supplements along with aspirin. Which nursing intervention has the highest priority?

• A. Advise the mother to withhold all medications by mouth.
• B. Instruct the mother to take the teen to the emergency room.
• C. Recommend that the teen withhold food and fluids for 2 hours.
• D. Suggest that the adolescent breathe slowly and deeply.

Correct answer: B

Rationale: In this scenario, the highest priority nursing intervention is to instruct the mother to take the teen to the emergency room. The symptoms of recurrent vomiting, combative behavior, and the medications (vitamins, calcium, magnesium supplements, and aspirin) taken by the teen suggest a possible overdose or serious adverse reaction. Therefore, immediate medical evaluation is crucial to assess and manage any potential toxicity or adverse effects. Advising to withhold all medications by mouth (Choice A) may delay necessary treatment. Recommending withholding food and fluids for 2 hours (Choice C) may not address the underlying cause of the symptoms. Suggesting slow and deep breathing (Choice D) is not appropriate in this urgent situation requiring immediate medical attention.

4. The nurse is assessing a client with chronic heart failure who is receiving furosemide (Lasix). Which assessment finding is most concerning?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Elevated liver enzymes
• D. Elevated blood glucose level

Correct answer: C

Rationale: Elevated liver enzymes are most concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. Elevated liver enzymes can be a sign of hepatotoxicity or liver damage, which could be a result of furosemide (Lasix) use. Monitoring liver function is crucial in patients taking furosemide due to the risk of hepatotoxicity. A heart rate of 60 beats per minute and a blood pressure of 110/70 mmHg are within normal ranges for a client with chronic heart failure. An elevated blood glucose level may be expected due to the effects of furosemide but is not as immediately concerning as elevated liver enzymes.

5. The nurse is assessing a client with left-sided heart failure. Which clinical finding requires immediate intervention?

• A. Jugular venous distention
• B. Shortness of breath
• C. Crackles in the lungs
• D. Peripheral edema

Correct answer: C

Rationale: Corrected Rationale: In a client with left-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention to prevent worsening heart failure symptoms and respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure but are not as critical as crackles in the lungs because they may indicate fluid overload or right-sided heart failure, which are important to address but not as urgently as managing pulmonary congestion.
