Question 1 of 5
The nurse is setting an infusion pump to deliver 4 mcg/kg/min of a medication to a patient who weighs 50 kg. How many micrograms should the patient receive in one hour?
Correct Answer: C
Rationale: To determine the correct answer, we first calculate the total micrograms the patient should receive in one hour. 1. Multiply the patient's weight (50 kg) by the infusion rate (4 mcg/kg/min) to get the total micrograms/min: 50 kg * 4 mcg/kg/min = 200 mcg/min. 2. To find the total micrograms in one hour, multiply the micrograms/min by 60 minutes: 200 mcg/min * 60 min = 12000 mcg. Therefore, the patient should receive 12,000 micrograms in one hour, making choice C the correct answer. Explanation for incorrect choices: A: 200 - This is the total micrograms per minute, not for the whole hour. B: 1200 - This is close to the correct answer, but it doesn't account for the full hour. D: 0 - This is incorrect as the patient should receive medication over the hour.
Question 2 of 5
The nurse assesses a stage III pressure ulcer. The nurse has observed which of the following?
Correct Answer: B
Rationale: The correct answer is B because a stage III pressure ulcer is characterized by an open wound with subcutaneous tissue exposed. This indicates significant tissue damage, making it a distinguishing feature of a stage III ulcer. Choice A is incorrect because redness that persists when pressure is relieved is indicative of a stage I pressure ulcer. Choice C is incorrect as it describes a stage IV ulcer, not stage III. Choice D is incorrect as it describes a stage II ulcer, not stage III.
Question 3 of 5
A patient on I. V. heparin should have which of the following laboratory values monitored closely to determine whether the therapeutic range is maintained?
Correct Answer: C
Rationale: The correct answer is C: Partial Thromboplastin Time (PTT). PTT measures the effectiveness of heparin as it reflects the clotting time. Monitoring PTT ensures the therapeutic range of heparin is maintained to prevent clotting or bleeding. Hemoglobin (A) monitors anemia, INR (B) is used to monitor Warfarin therapy, and Prothrombin Time (D) is used for monitoring Warfarin therapy, not heparin.
Question 4 of 5
A nurse is caring for an older client who exhibits dehydration-induced confusion. Which intervention by the nurse is best?
Correct Answer: C
Rationale: The correct answer is C: Increase the IV flow rate to 250 mL/hr. Dehydration-induced confusion requires prompt correction of fluid deficit. Increasing IV flow rate will help rehydrate the client more quickly, addressing the underlying cause of confusion. This intervention is directly related to resolving dehydration. A: Measuring intake and output every 4 hours is important for monitoring fluid balance but will not address dehydration promptly. B: Assessing the client further for fall risk is important but does not directly address the underlying cause of confusion. D: Placing the client in a high-Fowler position can help with respiratory issues but does not directly address dehydration-induced confusion.
Question 5 of 5
A patient’s 4 X 3-cm leg wound has a 0.4-cm black area in the center of the wound surrounded by yellow-green semiliquid material. Which dressing should the nurse apply to the wound?
Correct Answer: C
Rationale: The correct answer is C: Hydrocolloid dressing. This type of dressing is ideal for a wound with yellow-green semiliquid material, as it helps to maintain a moist environment which promotes wound healing. The black area in the center could indicate necrotic tissue, and the hydrocolloid dressing can help to facilitate autolytic debridement. Dry gauze dressing (A) would not be suitable as it can adhere to the wound bed, causing trauma during removal. Nonadherent dressing (B) may not provide adequate moisture for healing. Transparent film dressing (D) may not be ideal as it does not provide the same level of absorption and protection as a hydrocolloid dressing.
