Question 1 of 5
The healthcare provider prescribes Amoxicillin 500mg PO every 8hrs for a child who weighs 22 pounds. The available suspension is labeled Amoxicillin Suspension 250mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child's weight?
Correct Answer: A
Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs · 2.2 = 10 kg. The maximum dose based on weight would be 10 kg 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg · 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg · 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.
Question 2 of 5
The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?
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.
Question 3 of 5
While caring for a laboring client on continuous fetal monitoring, the nurse notes a fetal heart rate pattern that falls and rises abruptly with a 'V' shaped appearance. What action should the nurse take first?
Correct Answer: A
Rationale: In cases of fetal heart rate patterns showing abrupt falls and rises with a 'V' shaped appearance, it indicates possible cord compression. Changing the maternal position, such as moving the mother onto her side, can relieve the pressure off the cord and help improve fetal oxygenation, making it the priority intervention to address the decelerations.
Question 4 of 5
A full-term, 24-hour-old infant in the nursery regurgitates and suddenly turns cyanotic. What should the nurse do first?
Correct Answer: A
Rationale: In a situation where an infant regurgitates and turns cyanotic, the priority action should be to clear any potential airway obstruction. Suctioning the oral and nasal passages is crucial to ensure the infant's airway is clear and allow for proper breathing. This intervention takes precedence over providing oxygen, stimulating the infant to cry, or repositioning the infant.
Question 5 of 5
The healthcare provider is reviewing the serum laboratory findings for a 5-day-old infant with congenital adrenal hyperplasia. Which laboratory result should be reported to the healthcare provider immediately?
Correct Answer: D
Rationale: In this scenario, the correct laboratory result that should be reported to the healthcare provider immediately for a 5-day-old infant with congenital adrenal hyperplasia is option D) Sodium of 119 mEq/L. Sodium level is crucial in cases of congenital adrenal hyperplasia as this condition often leads to adrenal insufficiency, affecting the production of aldosterone which helps regulate sodium and potassium levels. A low sodium level, such as in this case, can indicate adrenal crisis which is a life-threatening condition requiring immediate medical attention. The other options are not as concerning in this context: - Option A) Bilirubin of 1.5 mg/dl is within normal range for a 5-day-old infant and does not indicate an urgent issue. - Option B) Glucose of 80 mg/dl is also within normal limits for a newborn and does not pose an immediate threat. - Option C) Potassium of 4.5 mEq/L is within the normal range and is not indicative of an urgent issue in this scenario. Educationally, this question highlights the importance of recognizing critical lab values in specific clinical conditions like congenital adrenal hyperplasia and reinforces the significance of prompt intervention in managing such cases to prevent serious complications.
