Nursing Elites

1. 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.

2. Why is complete bedrest necessary for a pregnant client with mitral stenosis Class III?

• A. Complete bedrest decreases oxygen needs and demands on the heart muscle tissue.
• B. We want your baby to be healthy, and this is the only way we can ensure that will happen.
• C. I know you're upset. Would you like to talk about some activities you could do while in bed?
• D. Labor is difficult, and you need to use this time to rest before assuming child-caring duties.

Correct answer: A

Rationale: Complete bedrest is necessary for a pregnant client with mitral stenosis Class III to reduce the workload on the heart, lower oxygen consumption, and prevent complications associated with cardiac conditions like mitral stenosis. By remaining in bed, the client can help maintain cardiac function and promote a safer pregnancy outcome. Choice B is incorrect as it does not provide a specific reason related to the client's medical condition. Choice C is not addressing the medical necessity of bedrest for this particular client. Choice D is irrelevant and does not explain the importance of bedrest for a pregnant client with mitral stenosis Class III.

3. The client is 24 weeks gestation and reports increased thirst and urination. Which diagnostic test result should the nurse report to the healthcare provider?

• A. Hemoglobin A1C.
• B. Postprandial blood glucose test.
• C. Oral glucose tolerance test.
• D. Fasting blood glucose.

Correct answer: C

Rationale: An abnormal oral glucose tolerance test result is indicative of gestational diabetes. This test is crucial in diagnosing gestational diabetes as it evaluates how well the body processes glucose after a sugary drink. Reporting abnormal results promptly allows for timely intervention and management to ensure the well-being of both the mother and the baby. The other options are not the primary tests used to diagnose gestational diabetes. Hemoglobin A1C is not recommended for diagnosing gestational diabetes as it reflects long-term glucose control. Postprandial blood glucose and fasting blood glucose tests are not as sensitive as the oral glucose tolerance test for diagnosing gestational diabetes.

4. The nurse is assessing a newborn who was precipitously delivered at 38 weeks' gestation. The newborn is tremulous, tachycardic, and hypertensive. Which assessment action is most important for the nurse to take?

• A. Perform a gestational age assessment.
• B. Obtain a drug screen for cocaine.
• C. Determine reactivity of neonatal reflexes.
• D. Weigh and measure the newborn.

Correct answer: B

Rationale: The correct answer is to obtain a drug screen for cocaine. Tremulousness, tachycardia, and hypertension in a newborn can be signs of neonatal abstinence syndrome, often caused by maternal drug use, such as cocaine. Identifying maternal drug use is crucial for appropriate management and treatment of the newborn.

5. What advice is most important for a client in the first trimester of pregnancy experiencing nausea?

• A. Practice relaxation techniques when nausea begins.
• B. Increase fluid intake to 3 quarts daily.
• C. Avoid alcohol, caffeine, and smoking.
• D. Eliminate snacks between meals.

Correct answer: C

Rationale: During the first trimester of pregnancy, it is crucial to advise pregnant clients to avoid alcohol, caffeine, and smoking. These substances can worsen nausea and harm fetal development. By eliminating these substances, the client can help alleviate nausea and create a healthier environment for the developing fetus. Choices A, B, and D are not as critical in managing nausea during the first trimester. While relaxation techniques may help, avoiding harmful substances like alcohol, caffeine, and smoking takes precedence. Increasing fluid intake can be beneficial but not as crucial as avoiding harmful substances. Eliminating snacks between meals may not be necessary for all clients and is not directly related to managing nausea in the first trimester.
