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. Following change-of-shift report on an orthopedic unit, which client should the nurse see first?
- A. 16-year-old who had an open reduction of a fractured wrist 10 hours ago
- B. 20-year-old in skeletal traction for 2 weeks since a motorcycle accident
- C. 72-year-old recovering from surgery after a hip replacement 2 hours ago
- D. 75-year-old who is in skin traction prior to planned hip pinning surgery
Correct answer: C
Rationale: The 72-year-old recovering from surgery after a hip replacement 2 hours ago should be seen first due to the potential for immediate post-operative complications. This patient is in the immediate postoperative period and requires close monitoring for any signs of complications such as bleeding, infection, or impaired circulation. The other patients are relatively stable compared to the patient who just had surgery and therefore can wait for assessment and care without immediate risk. The 16-year-old had surgery ten hours ago, which is longer than the 72-year-old and is at a lower risk for immediate complications. The 20-year-old in skeletal traction for two weeks is stable in his current condition. The 75-year-old in skin traction before planned surgery does not require immediate attention as the surgery has not yet taken place.
3. A client with chronic kidney disease is receiving epoetin alfa (Epogen). Which laboratory value should the LPN/LVN monitor to determine the effectiveness of this medication?
- A. Serum potassium
- B. Hemoglobin
- C. Serum creatinine
- D. Blood urea nitrogen (BUN)
Correct answer: B
Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.
4. A nurse in an outpatient clinic is caring for a client who has a new prescription for an antihypertensive medication. Which of the following instructions should the nurse give the client?
- A. “Get up and change positions slowly.”
- B. “Avoid eating aged cheese and smoked meat.”
- C. “Report any unusual bruising or bleeding to the doctor immediately.”
- D. “Eat the same amount of foods that contain vitamin K every day.”
Correct answer: A
Rationale: The correct instruction for the nurse to give the client who is starting on antihypertensive medication is to 'Get up and change positions slowly.' Antihypertensive medications can cause orthostatic hypotension, a drop in blood pressure when changing positions, so changing positions slowly helps prevent this adverse effect. Choice B about avoiding aged cheese and smoked meat is more relevant for clients taking monoamine oxidase inhibitors (MAOIs) due to potential interactions. Choice C regarding reporting unusual bruising or bleeding is more applicable for clients on anticoagulants. Choice D about consuming consistent amounts of vitamin K-containing foods daily is important for clients taking warfarin, not antihypertensive medications.
5. A healthcare provider is preparing to insert an IV catheter into a client's arm before starting IV fluid therapy. Which of the following interventions should the provider implement to prevent infection?
- A. Thread the IV catheter so that the hub rests at the insertion site
- B. Shave excess hair from around the insertion site
- C. Cleanse the site with hydrogen peroxide before IV catheter insertion
- D. Palpate the site carefully just before inserting the IV catheter
Correct answer: A
Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.
