Nursing Elites

1. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

2. A nurse is assessing a client who is receiving morphine via a patient-controlled analgesia (PCA) pump. The nurse should identify that which of the following findings is a manifestation of opioid toxicity?

• A. Bradypnea.
• B. Tachycardia.
• C. Hypertension.
• D. Diaphoresis.

Correct answer: A

Rationale: Corrected Rationale: Bradypnea, or slow breathing, is a common sign of opioid toxicity. When a client is experiencing opioid toxicity, the respiratory system is usually the most affected, leading to a decrease in the respiratory rate (bradypnea). Tachycardia (increased heart rate), hypertension (high blood pressure), and diaphoresis (excessive sweating) are not typical manifestations of opioid toxicity. Therefore, the correct answer is bradypnea.

3. A nurse is caring for a client who has a new prescription for metformin. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. You should avoid eating foods high in potassium.
• C. You should take this medication with meals to improve absorption.
• D. Take this medication before bed to prevent drowsiness.

Correct answer: C

Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals to improve absorption and reduce gastrointestinal upset. Metformin is typically recommended to be taken with food to minimize side effects. Option A is incorrect as taking metformin on an empty stomach may increase the risk of gastrointestinal side effects. Option B is unrelated as metformin does not interact with potassium-rich foods. Option D is also incorrect as metformin does not cause drowsiness, so there is no need to take it before bed.

4. A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. The client weighs 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, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.

5. A nurse is caring for a client who is receiving oxytocin to augment labor. The client's contractions are occurring every 90 seconds with a duration of 90 seconds. Which of the following actions should the nurse take?

• A. Increase oxytocin infusion.
• B. Decrease oxytocin infusion.
• C. Maintain oxytocin infusion.
• D. Discontinue oxytocin infusion.

Correct answer: D

Rationale: The correct action for the nurse to take in this scenario is to discontinue the oxytocin infusion. With contractions occurring every 90 seconds with a duration of 90 seconds, the contractions are too frequent and prolonged, which can lead to uterine rupture or fetal distress. Increasing or maintaining the oxytocin infusion would exacerbate the situation, potentially causing harm to the mother and fetus. Decreasing the oxytocin infusion might not be sufficient to address the issue, making discontinuation the most appropriate action to ensure the safety of both the client and the baby.
