Nursing Elites

1. 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.

2. A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor?

• A. Hemoglobin
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: aPTT. The activated partial thromboplastin time (aPTT) is monitored to assess the therapeutic effect of heparin and to adjust the infusion rate if needed. Monitoring hemoglobin levels (choice A) is important for assessing anemia but is not specific to heparin therapy. INR (choice C) is used to monitor the effects of warfarin, not heparin. Platelet count (choice D) is important to monitor for heparin-induced thrombocytopenia, but aPTT is the primary laboratory value used to monitor heparin therapy.

3. A client with COPD is receiving discharge teaching. Which statement indicates an understanding of the teaching?

• A. I will avoid breathing deeply while using my incentive spirometer.
• B. I will limit my fluid intake to 1 liter per day.
• C. I will exercise in an area that is humid.
• D. I will use pursed-lip breathing techniques.

Correct answer: D

Rationale: The correct answer is D. Using pursed-lip breathing techniques is beneficial for clients with COPD as it helps control shortness of breath by keeping airways open longer. Option A is incorrect as deep breathing while using an incentive spirometer is essential to prevent complications such as atelectasis. Option B is incorrect because limiting fluid intake to 1 liter per day is not a standard recommendation for clients with COPD. Option C is incorrect as exercising in a humid area can exacerbate breathing difficulties for clients with COPD.

4. A nurse is teaching a newly licensed nurse about using a portable oxygen system. What instruction should the nurse include?

• A. The oxygen should be kept in a storage room when not in use.
• B. Turn off the oxygen when not in use.
• C. Check the oxygen level regularly using a pulse oximeter.
• D. Never leave the oxygen running when transporting a client.

Correct answer: C

Rationale: The correct answer is to check the oxygen level regularly using a pulse oximeter. This instruction is crucial as it ensures safe and adequate oxygenation for the client. Option A is incorrect as oxygen should not be stored in a storage room but in a well-ventilated area. Option B is not ideal as oxygen should be left on unless otherwise specified by a healthcare provider. Option D is also important but not directly related to the primary instruction of monitoring oxygen levels.

5. What is the most important assessment for a patient with respiratory distress?

• A. Monitor oxygen saturation
• B. Check for abnormal breath sounds
• C. Check for pitting edema
• D. Perform a neurological exam

Correct answer: A

Rationale: Monitoring oxygen saturation is crucial in assessing a patient with respiratory distress because it helps determine if the patient is receiving adequate oxygen. Oxygen saturation levels provide immediate feedback on the efficiency of oxygen delivery to the tissues. Checking for abnormal breath sounds (Choice B) is relevant in respiratory assessments, but it is secondary to assessing oxygen saturation. Pitting edema (Choice C) and performing a neurological exam (Choice D) are not directly related to assessing respiratory distress and are not the primary focus when managing a patient with breathing difficulties.
