Nursing Elites

1. The healthcare provider is preparing to give an enema to a laboring client. Which client requires the most caution when carrying out this procedure?

• A. A gravida 6, para 5 who is 38 years of age and in early labor.
• B. A 37-week primigravida who presents at 100% effacement, 3 cm cervical dilation, and a -1 station.
• C. A gravida 2, para 1 who is at 1 cm cervical dilation and a 0 station admitted for induction of labor due to postdates.
• D. A 40-week primigravida who is at 6 cm cervical dilation and the presenting part is not engaged.

Correct answer: D

Rationale: The client at 40 weeks of gestation with a 6 cm cervical dilation and a presenting part that is not engaged requires the most caution during an enema procedure. An unengaged presenting part increases the risk of cord prolapse, which can be a serious complication during the procedure. This situation demands careful attention to prevent potential complications and ensure the safety of the client and fetus. Choice A is incorrect as being in early labor does not pose the same level of risk as an unengaged presenting part. Choice B describes a client at 37 weeks with signs of early labor but does not indicate the same level of risk as an unengaged presenting part. Choice C involves a client at 1 cm cervical dilation and a 0 station with no mention of an unengaged presenting part, making it a less critical situation compared to an unengaged presentation, as in Choice D.

2. What is the priority nursing assessment immediately following the birth of an infant with esophageal atresia and a tracheoesophageal (TE) fistula?

• A. Body temperature.
• B. Level of pain.
• C. Time of first void.
• D. Number of vessels in the cord.

Correct answer: D

Rationale: The priority nursing assessment immediately following the birth of an infant with esophageal atresia and a tracheoesophageal (TE) fistula is to check the number of vessels in the cord. This assessment is crucial to identify any potential anomalies related to the TE fistula, as abnormalities in the cord vessels may indicate associated congenital anomalies that need immediate attention.

3. The healthcare provider prescribes oxytocin 2 milliunits/minute to induce labor for a client at 41-weeks gestation. The nurse initiates an infusion of Ringer’s Lactate solution 1000 mL with oxytocin 10 units. How many mL/hour should the nurse program the infusion pump?

• A. 12 mL/hour
• B. 2 mL/hour
• C. 22 mL/hour
• D. 42 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate in mL/hour, first, convert 2 milliunits/minute to milliunits/hour by multiplying by 60 to get 120 milliunits/hour. Then, calculate the mL/hour using the formula: milliunits/hour (120) × total volume (1000 mL) ÷ units in IV solution (10 units) = 1200 mL/hour. Therefore, the nurse should program the infusion pump to deliver 12 mL/hour to provide the prescribed dose of oxytocin. Choice B is incorrect as it does not reflect the correct calculation. Choice C is incorrect as it is not derived from the correct formula. Choice D is incorrect as it is not the result of the accurate calculation based on the provided information.

4. 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?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

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.

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

• A. A home pregnancy test can be used right after your first missed period.
• B. These tests are most accurate after you have missed your second period.
• C. Home pregnancy tests often give false positives and should not be trusted.
• D. The test can provide accurate information when used right after ovulation.

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.
