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. The nurse is providing care for a client with heart failure who is prescribed furosemide. Which laboratory value should the nurse monitor closely?

• A. Calcium level
• B. Sodium level
• C. Magnesium level
• D. Potassium level

Correct answer: D

Rationale: The correct answer is D: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. While calcium, sodium, and magnesium levels are important in various conditions and treatments, they are not the primary electrolyte affected by furosemide.

3. A client with tuberculosis (TB) is being discharged on isoniazid and rifampin. What instruction should the nurse prioritize?

• A. Complete the full course of antibiotics.
• B. Notify the healthcare provider if you experience tingling in your fingers.
• C. Use a disposable mask when in contact with others.
• D. Monitor liver function tests monthly.

Correct answer: C

Rationale: The correct answer is to instruct the client to use a disposable mask when in contact with others. TB is highly contagious, and wearing a mask can help prevent the spread of the disease to others. Choice A is important but not the priority as using a mask directly impacts public health. Choice B is related to a potential side effect of isoniazid, peripheral neuropathy, but immediate healthcare provider notification is not required. Choice D is relevant due to the potential hepatotoxicity of isoniazid and rifampin, but it is not the priority instruction in this scenario.

4. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

5. A 78-year-old client with diabetes is being taught how to care for his feet. Which statement by the client indicates a need for further education?

• A. I will soak my feet in warm water every day.
• B. I will use a mirror to check my feet every day.
• C. I will apply lotion to my feet every day, avoiding the area between the toes.
• D. I will wear properly fitting shoes at all times.

Correct answer: A

Rationale: The correct answer is A. Soaking feet daily can lead to excessive moisture, which can increase the risk of skin breakdown or infection in diabetic clients. Choices B, C, and D are all correct statements for foot care in diabetic clients. Using a mirror for daily foot checks helps in early detection of any issues, applying lotion while avoiding the area between the toes helps keep the skin moisturized without creating a risk for fungal infections, and wearing properly fitting shoes is important to prevent pressure points and potential injuries.
