1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
- A. 8 mL/hr
- B. 10 mL/hr
- C. 12 mL/hr
- D. 15 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
2. During an admission history, a client tells a nurse that she is under a lot of stress. Which of the following physiological responses should the nurse expect to increase as a result of stress?
- A. Blood glucose - a common stress response.
- B. Intestinal peristalsis - should decrease due to stress.
- C. Peripheral blood vessels diameter - can vary in response to stress.
- D. Urine output - may vary but not a typical stress response.
Correct answer: A
Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.
3. The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?
- A. 42 gtt/min
- B. 83 gtt/min
- C. 125 gtt/min
- D. 250 gtt/min
Correct answer: B
Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL). In this case, 1000 mL ÷ 240 min ÷ 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.
4. A client reports constipation, and a nurse is providing dietary teaching. Which of the following foods should the nurse recommend?
- A. Macaroni and cheese
- B. One medium apple with skin
- C. One cup of plain yogurt
- D. Roast chicken and white rice
Correct answer: B
Rationale: The correct answer is B: One medium apple with skin. Foods high in fiber, like apples with skin, are recommended to relieve constipation due to their fiber content, which aids in bowel regularity. Macaroni and cheese, yogurt, and roast chicken with white rice do not provide as much fiber and are less effective in alleviating constipation. While yogurt can sometimes contain probiotics that support gut health, it is not as effective in treating constipation as high-fiber foods like apples.
5. A client with a new colostomy is being taught how to irrigate the ostomy. The healthcare provider realizes that the client needs further teaching when the client:
- A. Positions the irrigating solution bag 30 inches below the stoma
- B. Uses an open system for irrigation
- C. Irrigates the colostomy twice a day
- D. Cleans the stoma with harsh chemicals
Correct answer: A
Rationale: The correct answer is A. Positioning the irrigating solution bag 30 inches below the stoma would cause discomfort and ineffective irrigation as the bag should be positioned at a lower level. Option B is incorrect because a closed system for irrigation is the preferred method for colostomy irrigation. Option C is incorrect as colostomy irrigation is typically done once a day unless otherwise instructed by a healthcare provider. Option D is incorrect as the stoma should be cleaned with mild soap and water to prevent skin irritation and damage.
