1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?
- A. It dissolves blood clots
- B. It prevents the blood from clotting
- C. It thins the blood
- D. It decreases the risk of infection
Correct answer: B
Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.
2. The mother of a 6-year-old anemic boy is taught by the nurse to give iron supplements. Which statement indicates that the mother understands the proper administration of iron?
- A. The iron tablets will be absorbed between meals, on an empty stomach
- B. I should give the iron tablets with his milk and cereal each morning
- C. Iron preparations can be taken with antibiotics if he develops an infection
- D. The iron tablets may cause him to sunburn more easily so he should wear sunscreen
Correct answer: A
Rationale: The correct answer is A because iron supplements are best absorbed on an empty stomach, which maximizes their effectiveness. Giving iron tablets with milk or calcium-rich foods, as mentioned in choice B, should be avoided as they can decrease iron absorption. Choice C is incorrect because iron preparations should not be taken with antibiotics due to potential interactions. Choice D is also incorrect as iron tablets do not cause an increased risk of sunburn, so sunscreen is not necessary specifically due to iron supplementation.
3. Is it necessary to continue to strain the urine of a client with kidney stones since several stones were obtained the previous day?
- A. UAPs should follow the prescribed care without questioning it
- B. Yes, it is important to continue straining all the client's urine
- C. Measuring intake and output is equally important as straining the urine
- D. Ensuring that the client is free from pain should be the top priority
Correct answer: B
Rationale: Yes, it is important to continue straining all urine to catch any remaining stones. Straining the urine helps in identifying any new stones that may have formed, allowing for appropriate management. While measuring intake and output is important, straining the urine is specifically necessary in this case to monitor the presence of kidney stones. Ensuring the client is free from pain is essential, but in this situation, preventing further complications related to kidney stones is a higher priority.
4. The nurse is caring for a laboring 22-year-old primigravida following administration of regional anesthesia. In planning care for this client, what nursing intervention has the highest priority?
- A. Raising the side rails and placing the call bell within reach
- B. Teaching the client how to push effectively to decrease the length of the second stage of labor
- C. Timing and recording uterine contractions
- D. Positioning the client for proper distribution of anesthesia
Correct answer: A
Rationale: The highest priority nursing intervention for a laboring client following administration of regional anesthesia is to ensure safety by raising the side rails and placing the call bell within reach. This is crucial to prevent falls and to ensure that the client can call for assistance if needed. Teaching the client how to push effectively (Choice B) is important but not the highest priority at this moment. Timing and recording uterine contractions (Choice C) are essential but not as immediate as ensuring safety post-anesthesia. Positioning the client for proper distribution of anesthesia (Choice D) is important but ensuring immediate safety takes precedence in this situation.
5. When caring for a laboring client whose contractions are occurring every 2 to 3 min, the nurse should document that the pump is infusing how many ml/hr?
- A. 42
- B. 50
- C. 60
- D. 70
Correct answer: A
Rationale: To calculate the infusion rate, we first need to determine the frequency of contractions per hour. If contractions are occurring every 2 to 3 minutes, this corresponds to 20 to 30 contractions in an hour (60 minutes). The average is 25 contractions in an hour. The pump should be infusing 1 ml for each contraction, so the infusion rate should be 25 ml/hr. Therefore, the correct answer is 42 ml/hr. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.
