Nursing Elites

1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 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, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

2. A healthcare professional is reviewing admission prescriptions for a group of clients. Which of the following prescriptions should the healthcare professional identify as complete?

• A. Furosemide 20 mg BID.
• B. Aspirin 1 tablet daily.
• C. Nitroglycerin transdermal patch.
• D. Metoprolol 5 mg IV now.

Correct answer: D

Rationale: The correct answer is D because it provides the medication (Metoprolol), dosage (5 mg), route of administration (IV), and timing (now), making it a complete prescription. Choices A, B, and C lack either the route of administration or timing, making them incomplete prescriptions. For choice A, it lacks the route of administration, and for choices B and C, they lack the timing of administration.

3. What is the best intervention for a patient with respiratory distress?

• A. Administer oxygen
• B. Reposition the patient
• C. Provide bronchodilators
• D. Provide humidified air

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient with respiratory distress because it helps improve oxygenation levels and alleviates respiratory distress directly. Providing oxygen addresses the primary issue of inadequate oxygen supply, which is crucial in managing respiratory distress. Repositioning the patient, while important for airway clearance, may not address the immediate need for oxygen. Providing bronchodilators and humidified air can be beneficial in certain respiratory conditions, but when a patient is in respiratory distress, ensuring adequate oxygenation through oxygen administration takes precedence.

4. A nurse is caring for a client who has chronic kidney disease and a serum potassium level of 6.5 mEq/L. Which of the following actions should the nurse take?

• A. Administer sodium bicarbonate
• B. Administer sodium polystyrene sulfonate
• C. Administer calcium gluconate
• D. Administer calcium carbonate

Correct answer: B

Rationale: The correct action for the nurse to take is to administer sodium polystyrene sulfonate. This medication promotes potassium excretion and helps lower serum potassium levels in clients with hyperkalemia, which is indicated by a high potassium level. Sodium bicarbonate (choice A) is not used to treat hyperkalemia. Calcium gluconate (choice C) and calcium carbonate (choice D) are used to manage hyperkalemia by stabilizing cell membranes but are not the initial treatment choice for lowering potassium levels.

5. A healthcare professional is preparing to administer an IV bolus of morphine to a client. Which of the following actions should the healthcare professional take first?

• A. Check the client's respiratory rate.
• B. Administer naloxone.
• C. Check the client's pain level.
• D. Assess the client's blood pressure.

Correct answer: A

Rationale: Correct Answer: Checking the client's respiratory rate is the priority before administering morphine because morphine can depress respiration. This action helps the healthcare professional assess the client's baseline respiratory status and detect any potential respiratory depression that may be exacerbated by morphine. Choice B, administering naloxone, is incorrect because naloxone is used as an antidote for opioid overdose and not routinely administered before giving morphine. Choice C, checking the client's pain level, is important but not the first action to take before administering morphine. Choice D, assessing the client's blood pressure, is also important but not the initial priority compared to evaluating respiratory status when preparing to administer morphine.
