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 nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will avoid aspirin while taking this medication.
• B. I will increase my intake of green leafy vegetables.
• C. I will take this medication with an antacid.
• D. I should expect mild bruising around my elbows.

Correct answer: A

Rationale: The correct answer is A: "I will avoid aspirin while taking this medication." Clients taking warfarin should avoid aspirin due to the increased risk of bleeding. Choice B is incorrect because increasing the intake of green leafy vegetables high in Vitamin K can interfere with the effects of warfarin. Choice C is incorrect because warfarin should not be taken with antacids as they can decrease its absorption. Choice D is incorrect because mild bruising is a common side effect of warfarin due to its anticoagulant properties.

3. What is the priority nursing intervention for a patient experiencing respiratory distress?

• A. Administer oxygen
• B. Reposition the patient
• C. Administer bronchodilators
• D. Administer IV fluids

Correct answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, ensuring adequate oxygenation is the priority. Administering oxygen helps improve oxygen levels, which is crucial for the patient's well-being. Repositioning the patient, administering bronchodilators, or giving IV fluids are important interventions in certain situations, but when a patient is in respiratory distress, providing oxygen takes precedence over other actions.

4. A client in end-stage osteoporosis is reporting severe pain, with a respiratory rate of 14 per minute. Which of the following medications should the nurse expect to be the highest priority to administer to the client?

• A. Promethazine
• B. Hydromorphone
• C. Ketorolac
• D. Amitriptyline

Correct answer: B

Rationale: In a client with severe pain like the one described, the priority medication to administer is a potent analgesic like hydromorphone. Hydromorphone is a strong opioid pain medication that can effectively manage severe pain. Promethazine (Choice A) is an antiemetic and antihistamine, not a pain medication. Ketorolac (Choice C) is a nonsteroidal anti-inflammatory drug (NSAID) that is contraindicated in end-stage renal disease due to its potential to cause kidney damage. Amitriptyline (Choice D) is a tricyclic antidepressant used for conditions like depression and neuropathic pain, but it is not the first-line treatment for severe acute pain.

5. How should a healthcare provider monitor a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.
