Nursing Elites

1. When counseling a couple seeking information about conceiving, the LPN/LVN should know that ovulation usually occurs

• A. two weeks before menstruation.
• B. immediately after menstruation.
• C. immediately before menstruation.
• D. three weeks before menstruation.

Correct answer: A

Rationale: Ovulation typically occurs about 14 days before the start of the next menstrual period. This timing allows for the released egg to travel down the fallopian tube where it may be fertilized by sperm, leading to conception. Understanding the timing of ovulation is crucial for couples trying to conceive to increase their chances of success.

2. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.

3. A client with no prenatal care arrives at the labor unit screaming, 'The baby is coming!' The nurse performs a vaginal examination that reveals the cervix is 3 centimeters dilated and 75% effaced. What additional information is most important for the LPN/LVN to obtain?

• A. Gravidity and parity.
• B. Time and amount of last oral intake.
• C. Date of last normal menstrual period.
• D. Frequency and intensity of contractions.

Correct answer: C

Rationale: Obtaining the date of the last normal menstrual period is crucial in estimating the gestational age of the fetus. This information helps in determining the progression of labor and the management of delivery. It also assists healthcare providers in assessing the overall health of the mother and the fetus. Choices A, B, and D are important in labor assessment, but in this scenario, the most crucial information needed is the date of the last normal menstrual period to estimate the gestational age.

4. Twenty-four hours after admission to the newborn nursery, a full-term male infant develops localized edema on the right side of his head. The LPN/LVN knows that, in the newborn, an accumulation of blood between the periosteum and skull which does not cross the suture line is a newborn variation known as

• A. a cephalhematoma, caused by birth trauma and may last up to 8 weeks.
• B. a subarachnoid hematoma, which requires immediate drainage to prevent further complications.
• C. molding, caused by pressure during labor and will disappear within 2 to 3 days.
• D. a subdural hematoma, which can result in lifelong damage.

Correct answer: A

Rationale: Cephalhematoma is the accumulation of blood between the periosteum and skull, often due to birth trauma, and typically resolves within weeks. It is a common finding in newborns and is not usually a cause for concern as it gradually resolves without specific treatment. Subarachnoid hematoma and subdural hematoma are different conditions that present with distinct characteristics and require different management strategies. Therefore, the correct answer is A. Subarachnoid hematoma is typically found in the subarachnoid space and requires immediate intervention, not just observation like cephalhematoma. Molding refers to the shaping of the fetal head during passage through the birth canal and is a temporary change, not a collection of blood like in cephalhematoma. Subdural hematoma is located beneath the dura mater and is associated with significant complications, unlike the self-limiting nature of cephalhematoma.

5. 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.
