Nursing Elites

1. Using Nägele's rule, what is the estimated date of delivery for a pregnant client who reports that the first day of her last menstrual period was August 2, 2006?

• A. April 25, 2007.
• B. May 9, 2007.
• C. May 29, 2007.
• D. June 2, 2007.

Correct answer: B

Rationale: Nägele's rule is used to estimate the date of delivery. It involves adding 7 days to the first day of the last menstrual period (August 2), which gives August 9. Then, subtracting 3 months from August 9, we arrive at May 9 of the following year as the estimated date of delivery. This makes choice B, 'May 9, 2007,' the correct answer. Choices A, C, and D are incorrect as they do not follow the correct calculation based on Nägele's rule.

2. During a prenatal visit, the nurse discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

3. 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.

4. A 5-year-old child is admitted to the pediatric unit with fever and pain secondary to a sickle cell crisis. Which intervention should the nurse implement first?

• A. Obtain a culture of any sputum or wound drainage
• B. Initiate normal saline IV at 50 ml/hr
• C. Administer a loading dose of penicillin IM
• D. Administer the initial dose of folic acid PO

Correct answer: B

Rationale: In a child with a sickle cell crisis, the priority intervention is to initiate normal saline IV at 50 ml/hr to manage dehydration and help alleviate pain. This intervention helps improve hydration status and supports the circulation of sickled red blood cells, reducing the risk of vaso-occlusive episodes and associated pain. Obtaining a culture of any sputum or wound drainage (Choice A) may be necessary but is not the initial priority. Administering a loading dose of penicillin IM (Choice C) is important but not the first intervention. Administering the initial dose of folic acid PO (Choice D) is beneficial but does not address the immediate need for hydration in a sickle cell crisis.

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.
