1. At 14-weeks gestation, a client arrives at the Emergency Center complaining of a dull pain in the right lower quadrant of her abdomen. The LPN/LVN obtains a blood sample and initiates an IV. Thirty minutes after admission, the client reports feeling a sharp abdominal pain and shoulder pain. Assessment findings include diaphoresis, a heart rate of 120 beats/minute, and a blood pressure of 86/48. Which action should the nurse implement next?
- A. Check the hematocrit results.
- B. Administer pain medication.
- C. Increase the rate of IV fluids.
- D. Monitor the client for contractions.
Correct answer: C
Rationale: The client's symptoms suggest hypovolemic shock, possibly due to an ectopic pregnancy. Increasing IV fluids is crucial to stabilize the client by improving blood pressure and perfusion. This intervention helps address the underlying issue of hypovolemia and supports the client's hemodynamic status, which takes priority in this emergent situation.
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. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?
- A. Betamethasone (Celestone).
- B. Magnesium sulfate.
- C. Terbutaline (Brethine).
- D. Ampicillin.
Correct answer: A
Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.
4. 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.
5. After administering the varicella vaccine to a 5-year-old child, which instruction should the nurse provide the child’s parent?
- A. Chewable children’s aspirin will not help prevent inflammation.
- B. Keep the child home for the next two days.
- C. Any fever should be monitored and reported if severe.
- D. Apply a cool pack to the injection site to reduce discomfort.
Correct answer: D
Rationale: After receiving the varicella vaccine, applying a cool pack to the injection site can help reduce discomfort. This intervention is a simple and effective way to manage local reactions at the site of the vaccination, providing comfort to the child and potentially reducing swelling or pain. Choices A, B, and C are incorrect because chewable children’s aspirin is not typically recommended after vaccination, keeping the child home is not necessary unless advised by a healthcare provider, and monitoring fever alone is not the primary instruction post-varicella vaccination.
