Nursing Elites

1. At 20 weeks gestation, a client is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?

• A. Sex and size of the fetus.
• B. Chromosomal abnormalities.
• C. Fetal growth and gestational age.
• D. Lecithin-sphingomyelin ratio.

Correct answer: C

Rationale: The primary reason for an ultrasound at 20 weeks gestation is to assess fetal growth, gestational age, and anatomical development. This evaluation helps ensure the fetus is developing appropriately and can detect any potential issues that may require intervention. Choices A, B, and D are incorrect because at 20 weeks, the primary focus of the ultrasound is not to determine the sex of the fetus, detect chromosomal abnormalities, or assess the lecithin-sphingomyelin ratio. While these factors may be evaluated in pregnancy, they are not the primary reasons for an ultrasound at 20 weeks gestation.

2. The nurse is caring for a 5-year-old child with Reye’s syndrome. Which goal of treatment most clearly relates to caring for this child?

• A. Reduce cerebral edema and lower intracranial pressure
• B. Avert hypotension and septic shock
• C. Prevent cardiac arrhythmias and heart failure
• D. Promote kidney perfusion and normal blood pressure

Correct answer: A

Rationale: Reducing cerebral edema and lowering intracranial pressure is the primary goal of treatment for Reye’s syndrome.

3. At 40-weeks gestation, a client presents to the obstetrical floor with spontaneous rupture of amniotic membranes at home, in active labor, and feeling the urge to push. What information should the nurse prioritize obtaining?

• A. Color and consistency of fluid.
• B. Estimated amount of fluid.
• C. Any odor noted at the rupture of membranes.
• D. Time of membrane rupture.

Correct answer: A

Rationale: Assessing the color and consistency of amniotic fluid is crucial as it can indicate the presence of meconium, which suggests potential fetal distress. This information guides the need for further assessments and interventions to ensure the well-being of the mother and fetus. Estimating the amount of fluid is not as critical as determining the color and consistency to identify fetal distress. While noting any odor is important, it is secondary to assessing the fluid itself. Knowing the time of membrane rupture is helpful but not as crucial as evaluating the characteristics of the amniotic fluid.

4. A male infant with a 2-day history of fever and diarrhea is brought to the clinic by his mother, who tells the nurse that the child refuses to drink anything. The nurse determines that the child has a weak cry with no tears. Which intervention is most important to implement?

• A. Provide a bottle of electrolyte solution.
• B. Infuse normal saline intravenously.
• C. Administer an antipyretic rectally.
• D. Apply an external cooling blanket.

Correct answer: B

Rationale: Infusing normal saline intravenously is crucial to treat dehydration caused by fever and diarrhea. In this scenario, the infant's weak cry with no tears indicates severe dehydration, necessitating rapid fluid replacement via intravenous normal saline to restore fluid balance and prevent complications.

5. 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.
