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. When providing oral care for an unconscious client, which of the following actions should the nurse take?
- A. Place the client in a lateral position with the head turned to the side before beginning the procedure.
- B. Insert a suction catheter before brushing the teeth.
- C. Use a soft-bristled toothbrush only with water.
- D. Brush the client's teeth while they are in a supine position.
Correct answer: A
Rationale: When providing oral care for an unconscious client, it is essential to place them in a lateral position with the head turned to the side before beginning the procedure. This positioning helps prevent aspiration by allowing fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Inserting a suction catheter before brushing the teeth (Choice B) is not recommended as it can cause discomfort and increase the risk of oral tissue injury. Using a soft-bristled toothbrush only with water (Choice C) is not sufficient for effective oral care as toothpaste helps in removing plaque and bacteria. Brushing the client's teeth while they are in a supine position (Choice D) is not safe as it increases the risk of aspiration since fluids can easily enter the airway in this position.
3. A client is on bed rest following an abdominal surgery. Which of the following findings indicates the need to increase the frequency of position changes?
- A. Flat rash on the client's ankle
- B. Non-blanching red area over the client's trochanter
- C. Ecchymosis on the client's left shoulder
- D. Petechiae on the client's right anterior thigh
Correct answer: B
Rationale: The presence of a non-blanching red area over the client's trochanter is a concerning finding as it indicates possible pressure ulcer formation. This finding necessitates an increase in the frequency of position changes to prevent skin breakdown. Choices A, C, and D do not directly correlate with the need for increased position changes. A flat rash, ecchymosis, and petechiae may have different causes and would not be addressed by changing the client's position more frequently.
4. Which anatomical location is associated with the deep tendon reflex known as the patellar reflex?
- A. Knee picture
- B. Ankle picture
- C. Elbow picture
- D. Wrist picture
Correct answer: A
Rationale: The patellar reflex, also called the knee-jerk reflex, is elicited by tapping the patellar tendon just below the patella. This reflex involves the quadriceps muscle and the femoral nerve. The correct answer is 'A: Knee picture' because the patellar reflex is associated with the knee joint. Choices B, C, and D are incorrect as they do not correspond to the anatomical location involved in the patellar reflex.
5. The nurse is caring for a client with diabetes insipidus. Which finding should the LPN/LVN report to the healthcare provider?
- A. Weight gain
- B. Increased urine output
- C. Low blood pressure
- D. Thirst
Correct answer: B
Rationale: The correct answer is B: Increased urine output. In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), leading to the excretion of large amounts of dilute urine. Reporting increased urine output is crucial as it is a hallmark sign of diabetes insipidus. Weight gain (choice A) is not typically associated with diabetes insipidus; instead, clients may experience weight loss due to fluid loss. Low blood pressure (choice C) can be a complication of diabetes insipidus due to dehydration from excessive urination, but the priority finding to report is the increased urine output. Thirst (choice D) is a common symptom of diabetes insipidus due to the body's attempt to compensate for fluid loss, but it is not the most critical finding to report.
