1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?
- A. 400 mg
- B. 200 mg
- C. 1600 mg
- D. 100 mg
Correct answer: A
Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.
2. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?
- A. 1/2 tablet.
- B. 1 tablet.
- C. 1 1/2 tablets.
- D. 2 tablets.
Correct answer: C
Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.
3. A client who is 3 days post-op following a cholecystectomy has yellow and thick drainage on the dressing. The nurse suspects a wound infection. The nurse identifies this type of drainage as:
- A. Purulent
- B. Serous
- C. Sanguineous
- D. Serosanguineous
Correct answer: A
Rationale: The correct answer is A: Purulent. Purulent drainage is thick, yellow, and indicates the presence of infection. This type of drainage is typically seen in infected wounds. Choice B, Serous drainage, is thin, clear, and watery, which is normal in the initial stages of wound healing. Sanguineous drainage, choice C, is bright red and indicates fresh bleeding. Serosanguineous drainage, choice D, is pale pink to red and is a mixture of blood and serous fluid commonly seen in the early stages of wound healing.
4. A healthcare professional is calculating a client's fluid intake over the past 8 hr. Which of the following should the healthcare professional plan to document on the client's intake and output record as 120 mL of fluid?
- A. 8 oz of ice chips
- B. 8 oz of ice chips
- C. 1 cup of broth
- D. 1 cup of broth
Correct answer: A
Rationale: Choice A, '8 oz of ice chips,' is the correct answer. 8 oz is equivalent to approximately 240 mL, and since 1 oz is roughly equal to 30 mL, 8 oz would be approximately 240 mL. Since the question specifies 120 mL of fluid, this option does not match. Choices C and D, '1 cup of broth,' do not equate to 120 mL. A standard cup is approximately 240 mL, which is double the amount mentioned in the question. Therefore, choice A is the most accurate representation of 120 mL of fluid intake.
5. The client has a nasogastric (NG) tube in place for decompression. What action should the LPN/LVN take to maintain patency of the NG tube?
- A. Irrigate the tube with normal saline every shift.
- B. Check the tube placement by auscultation.
- C. Secure the tube to the client's gown.
- D. Flush the tube with 5 mL of sterile water before and after medication administration.
Correct answer: A
Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.
