1. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.

2. When can a woman who thinks she may be pregnant use a home pregnancy test to diagnose pregnancy?

Correct answer: A

Rationale: The correct answer is A. Home pregnancy tests detect hCG, a hormone produced during pregnancy, and are most accurate after the first missed period when hCG levels are higher. Testing too early may result in a false negative. Waiting until after the first missed period increases the reliability of the test results. Choice B is incorrect as waiting until after the second missed period is unnecessary and may delay seeking appropriate healthcare. Choice C is incorrect as home pregnancy tests are generally reliable when used correctly. Choice D is incorrect because ovulation occurs before the period, and testing immediately after ovulation may not provide accurate results.

3. A 28-year-old client in active labor complains of cramps in her leg. What intervention should be implemented?

Correct answer: B

Rationale: During active labor, if a client complains of leg cramps, extending the leg and dorsiflexing the foot can help relieve the muscle cramps by stretching the affected muscles. This intervention promotes circulation and can alleviate discomfort associated with leg cramps.

4. In assessing a 9-year-old boy admitted to the hospital with possible acute post-streptococcal glomerulonephritis (APSGN), what information is most significant to obtain in his history?

Correct answer: C

Rationale: A recent sore throat is most significant in this case as it could indicate a preceding streptococcal infection, which is a crucial factor in diagnosing APSGN. Streptococcal infection often precedes APSGN, and recognizing this history is essential for appropriate management and treatment. Choices A, B, and D are less relevant in the context of APSGN. Back pain and diuresis are symptoms that may not directly correlate with APSGN, while a history of hypertension, although important in general health assessment, is not as specific to the current scenario compared to a recent sore throat.

5. When a client delivers a viable infant but experiences excessive uncontrolled vaginal bleeding after the IV Pitocin infusion, what information is most important for the nurse to provide when notifying the healthcare provider?

Correct answer: A

Rationale: In a situation where a client is experiencing excessive uncontrolled vaginal bleeding post-delivery, the most crucial information for the nurse to provide the healthcare provider is the maternal blood pressure. Maternal blood pressure can help assess the severity of the bleeding and guide immediate interventions to stabilize the client's condition. Estimated blood loss, length of labor, and amount of IV fluids administered are important pieces of information but in this scenario, maternal blood pressure takes precedence as it directly indicates the client's current hemodynamic status.
