1. A client who is lactating is being taught about taking medications by a nurse. Which of the following actions should the nurse recommend to minimize the entry of medication into breast milk?
- A. Drink 8 oz of water with each dose of medication.
- B. Use medications that have a short half-life.
- C. Take each dose right after breastfeeding.
- D. Pump breast milk and discard it prior to feeding the newborn.
Correct answer: C
Rationale: Taking medications immediately after breastfeeding helps minimize the amount of medication that enters breast milk. By doing so, there is a longer interval between the medication intake and the next breastfeeding session, reducing the concentration of the medication in breast milk. Options A and B are incorrect as drinking water with medication or using medications with a short half-life do not directly minimize the entry of medication into breast milk. Option D is unnecessary and wasteful as pumping and discarding breast milk before feeding is not as effective as timing medication intake with breastfeeding to reduce medication transfer into breast milk.
2. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?
- A. Blood glucose level
- B. Prothrombin time (PT) and INR
- C. Serum potassium level
- D. Serum creatinine level
Correct answer: B
Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.
3. A healthcare professional is planning care for a female client who has an indwelling urinary catheter. Which of the following actions should the healthcare professional include in the plan?
- A. Empty the drainage bag at least every 8 hours
- B. Keep the drainage bag below the level of the bladder
- C. Use sterile technique to collect a specimen from the drainage system
- D. Secure the catheter to the lower abdomen with a securement device
Correct answer: B
Rationale: The correct action to include in the plan is to keep the drainage bag below the level of the bladder. This positioning helps ensure proper drainage and prevents backflow of urine into the bladder, reducing the risk of urinary tract infections. Emptying the drainage bag regularly is important, typically every 4-8 hours or when it is half-full, to maintain adequate flow and prevent infection (Choice A is incorrect). Using a sterile technique to collect specimens from the drainage system is crucial to prevent introducing pathogens into the urinary tract, so clean technique should not be used (Choice C is incorrect). Taping the catheter to the lower abdomen is not recommended as it can cause tension on the catheter, leading to discomfort and potential trauma to the urethra (Choice D is incorrect).
4. The provider orders Lanoxin (digoxin) 0.125 mg PO and furosemide 40 mg every day. Which of these foods would the nurse reinforce for the client to eat at least daily?
- A. Spaghetti
- B. Watermelon
- C. Chicken
- D. Tomatoes
Correct answer: B
Rationale: The correct answer is B: Watermelon. Watermelon is high in potassium, which is important to eat daily when taking furosemide to prevent hypokalemia. Furosemide is a diuretic that can lead to potassium loss, so consuming potassium-rich foods like watermelon helps maintain adequate potassium levels. Spaghetti, chicken, and tomatoes are not as high in potassium and therefore not as beneficial in preventing hypokalemia related to furosemide use.
5. 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.
