1. When interviewing the parents of a child with asthma, what information about the child's environment should be gathered most importantly?
- A. Household pets
- B. New furniture
- C. Lead-based paint
- D. Plants such as cactus
Correct answer: A
Rationale: When assessing a child with asthma, it is crucial to gather information about potential triggers in their environment. Household pets, such as cats or dogs, are common triggers for asthma attacks due to pet dander and saliva. This information is essential to identify if exposure to pets at home could be exacerbating the child's asthma symptoms. Choices B, C, and D are less relevant in the context of asthma triggers. New furniture, lead-based paint, and plants like cactus are not typically primary triggers for asthma attacks compared to common allergens like pet dander.
2. The client is being discharged and has been prescribed furosemide (Lasix). Which statement by the client indicates an understanding of the medication?
- A. I will take this medication on an empty stomach for optimal absorption.
- B. I will weigh myself daily and report any significant weight loss.
- C. I will include potassium-rich foods in my diet while taking this medication.
- D. I will take this medication in the morning to prevent nocturia.
Correct answer: B
Rationale: The correct answer is B. Weighing daily and reporting significant weight loss is crucial when taking furosemide to monitor for potential fluid and electrolyte imbalances. Choice A is incorrect because furosemide is typically taken on an empty stomach for optimal absorption. Choice C is incorrect as furosemide can lead to potassium loss, so potassium-rich foods should be consumed. Choice D is incorrect because furosemide is usually taken earlier in the day to prevent nocturia, not at bedtime.
3. A nurse is calculating a client's fluid intake over the past 8 hr. Which of the following items should the nurse plan to document on the client's intake and output record as 120 mL of fluid?
- A. 2 cups of soup
- B. 1 quart of water
- C. 8 oz of ice chips
- D. 6 oz of tea
Correct answer: C
Rationale: The correct answer is C: 8 oz of ice chips. When calculating fluid intake, the nurse should document half of the volume of ice chips to account for the air in between the chips. Therefore, 8 oz of ice chips equals 120 mL of fluid. Choices A, B, and D are incorrect because they do not equate to 120 mL of fluid intake as per the given scenario. Choice A, 2 cups of soup, is more than 120 mL. Choice B, 1 quart of water, is significantly more than 120 mL. Choice D, 6 oz of tea, is less than 120 mL.
4. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?
- A. 80
- B. 8
- C. 21
- D. 25
Correct answer: C
Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.
5. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
