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 client is postoperative following cataract surgery. Which of the following instructions should the nurse include?

• A. Avoid lying flat for 24 hours after surgery.
• B. Avoid bending at the waist.
• C. Wear an eye patch at night for 1 week.
• D. Sleep on your affected side to reduce discomfort.

Correct answer: B

Rationale: The correct instruction that the nurse should include for a client postoperative following cataract surgery is to avoid bending at the waist. Bending at the waist can increase intraocular pressure, which is not recommended after cataract surgery. Choices A, C, and D are incorrect because lying flat for 24 hours after surgery may not be necessary, wearing an eye patch at night for a week is not a standard postoperative instruction for cataract surgery, and sleeping on the affected side may not necessarily reduce discomfort and can increase pressure on the eye.

3. A nurse is preparing to insert an indwelling urinary catheter for a female client. Which of the following actions should the nurse take?

• A. Perform perineal care before the procedure.
• B. Apply sterile gloves before cleansing the perineal area.
• C. Place the client in a supine position.
• D. Lubricate the catheter with alcohol-based gel.

Correct answer: B

Rationale: Before inserting an indwelling urinary catheter for a female client, the nurse should apply sterile gloves before cleansing the perineal area to prevent infection. Performing perineal care before the procedure is incorrect as it should be done after catheter insertion. Placing the client in a side-lying position is not necessary for this procedure. Lubricating the catheter with petroleum jelly is not recommended as it can damage the catheter; using a water-soluble lubricant is preferred.

4. A client who is at 10 weeks of gestation is being taught about nutrition during pregnancy. Which statement by the client indicates an understanding of the teaching?

• A. I should consume 1,200 calories per day.
• B. I should increase my daily intake of folic acid.
• C. I should drink 2 liters of water each day.
• D. I should limit my intake of iron-rich foods.

Correct answer: B

Rationale: The correct answer is B. Increasing folic acid intake is crucial during pregnancy to prevent neural tube defects. Option A is incorrect because calorie requirements during pregnancy vary and are generally higher than 1,200 calories per day. Option C is not specific to pregnancy nutrition teaching, although hydration is important. Option D is incorrect as iron-rich foods are typically recommended during pregnancy to prevent anemia.

5. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory tests should the nurse use to monitor the client's therapeutic response to the medication?

• A. INR
• B. aPTT
• C. Platelet count
• D. Hemoglobin A1C

Correct answer: A

Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.
