Nursing Elites

1. A 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?

• A. Slowly increasing urinary output over the last week.
• B. Respiratory rate changes from the 40s to the 60s.
• C. Changes in apical heart rate from the 180s to the 140s.
• D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.

Correct answer: C

Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective. Choices A, B, and D are incorrect because they do not directly reflect the expected outcome of epoetin alfa therapy. Increasing urinary output, changes in respiratory rate, and decreasing bilirubin levels are not primary indicators of the drug's effectiveness in this context.

2. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.

3. During a well-child visit for their child, one of the parents with an autosomal dominant disorder tells the nurse, 'We don’t plan on having any more children, since the next child is likely to inherit this disorder.' How should the nurse respond?

• A. Explain that the risk of inheriting the disorder decreases by 50% with each child the couple has.
• B. Acknowledge that the next child will inherit the disorder since the first child did not.
• C. Encourage the couple to reconsider their decision since the inheritance pattern may be sex-linked.
• D. Confirm that there is a 50% chance of their future children inheriting the disorder.

Correct answer: D

Rationale: Confirming that there is a 50% chance of their future children inheriting the disorder is the correct response in this situation. Autosomal dominant disorders have a 50% chance of being passed on to each child. Providing accurate genetic counseling is essential to help the parents make informed decisions about family planning. Choices A, B, and C are incorrect. Choice A is inaccurate because the risk of inheriting an autosomal dominant disorder remains at 50% for each child regardless of the number of children the couple has. Choice B is not appropriate as it does not provide helpful information or support to the parents. Choice C is misleading because autosomal dominant disorders follow a specific inheritance pattern and are not sex-linked.

4. A client at 28 weeks gestation calls the antepartum clinic and reports experiencing a small amount of bright red vaginal bleeding without uterine contractions or abdominal pain. What instruction should the LPN/LVN provide?

• A. Come to the clinic today for an ultrasound.
• B. Go immediately to the emergency room.
• C. Lie on your left side for about one hour and see if the bleeding stops.
• D. Bring a urine specimen to the lab tomorrow to determine if you have a urinary tract infection.

Correct answer: A

Rationale: Bright red vaginal bleeding without pain could indicate placental issues such as previa. An ultrasound is necessary to evaluate the cause. It is important to rule out potential serious conditions like placental previa, which can lead to further complications for both the mother and the fetus. Therefore, prompt evaluation through an ultrasound at the clinic is essential for appropriate management and ensuring the well-being of the client and her baby.

5. The nurse is caring for a postpartum client who is exhibiting symptoms of a spinal headache 24 hours following the delivery of a normal newborn. Prior to the anesthesiologist's arrival on the unit, which action should the nurse perform?

• A. Apply an abdominal binder.
• B. Cleanse the spinal injection site.
• C. Insert an indwelling Foley catheter.
• D. Place procedure equipment at the bedside.

Correct answer: A

Rationale: In a postpartum client exhibiting symptoms of a spinal headache, applying an abdominal binder is a priority action. The abdominal binder can help reduce the severity of a spinal headache by increasing intra-abdominal pressure, which may relieve pressure on the dural sac and alleviate symptoms. This intervention can be performed promptly by the nurse to provide immediate relief while waiting for further evaluation and management by the anesthesiologist. Cleansing the spinal injection site (Choice B) is not the priority in this situation as the headache is likely due to a dural puncture during epidural anesthesia rather than infection. Inserting an indwelling Foley catheter (Choice C) and placing procedure equipment at the bedside (Choice D) are not the appropriate actions to address a spinal headache and should not take precedence over applying an abdominal binder.
