Nursing Elites

1. The LPN/LVN is counseling a woman who wants to become pregnant. The woman tells the nurse that she has a 36-day menstrual cycle and the first day of her last menstrual period was January 8. The nurse calculates that the woman's next fertile period is

• A. January 14-15.
• B. January 22-23.
• C. January 30-31.
• D. February 6-7.

Correct answer: C

Rationale: To determine the fertile period, subtract 14 days from the length of the woman's menstrual cycle. In this case, 36-14 = 22. Counting forward from the first day of the last menstrual period (January 8), the fertile period falls around January 30-31. This is because ovulation typically occurs approximately 14 days before the start of the next menstrual period, marking the fertile window for conception.

2. What is the most important assessment for the healthcare provider to conduct before the administration of epidural anesthesia to a client at 40 weeks' gestation?

• A. Maternal blood pressure.
• B. Level of pain sensation.
• C. Station of presenting part.
• D. Variability of fetal heart rate.

Correct answer: A

Rationale: Assessing maternal blood pressure is crucial before administering epidural anesthesia because it can cause hypotension, affecting both the mother and the fetus. Hypotension can lead to decreased placental perfusion, potentially compromising the fetal oxygen supply. Monitoring and maintaining maternal blood pressure within a safe range are essential to ensure the well-being of both the mother and the fetus during the administration of epidural anesthesia. The other options, such as assessing the level of pain sensation, station of presenting part, and variability of fetal heart rate, are important in obstetric care but are not as critical as monitoring maternal blood pressure to prevent complications related to epidural anesthesia administration.

3. A 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?

• A. Slowly increasing urinary output over the last week.
• B. Respiratory rate changes from the 40s to the 60s.
• C. Changes in apical heart rate from the 180s to the 140s.
• D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.

Correct answer: C

Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective. Choices A, B, and D are incorrect because they do not directly reflect the expected outcome of epoetin alfa therapy. Increasing urinary output, changes in respiratory rate, and decreasing bilirubin levels are not primary indicators of the drug's effectiveness in this context.

4. After each feeding, a 3-day-old newborn is spitting up large amounts of Enfamil® Newborn Formula, a nonfat cow's milk formula. The pediatric healthcare provider changes the neonate's formula to Similac® Soy Isomil® Formula, a soy protein isolate-based infant formula. What information should the LPN/LVN provide to the mother about the newly prescribed formula?

• A. The new formula is a coconut milk formula used with babies with impaired fat absorption.
• B. Enfamil® Formula is a demineralized whey formula that is needed with diarrhea.
• C. The new formula is a casein protein source that is low in phenylalanine.
• D. Similac® Soy Isomil® Formula is a soy-based formula that contains sucrose.

Correct answer: D

Rationale: The LPN/LVN should inform the mother that Similac® Soy Isomil® Formula is a soy-based formula containing sucrose. This formula is suitable for infants with cow's milk protein allergy or intolerance, which may be the reason for the newborn spitting up large amounts of the previous cow's milk formula.

5. A client at 32 weeks gestation is hospitalized with severe pregnancy-induced hypertension (PIH), and magnesium sulfate is prescribed to control the symptoms. Which assessment finding indicates the therapeutic drug level has been achieved?

• A. 4+ reflexes
• B. Urinary output of 50 ml per hour
• C. A decrease in respiratory rate from 24 to 16
• D. A decreased body temperature

Correct answer: C

Rationale: A decrease in respiratory rate from 24 to 16 indicates that magnesium sulfate is effectively reducing central nervous system irritability, a desired therapeutic effect. This decrease in respiratory rate signifies that the drug has reached a therapeutic level to control symptoms of severe pregnancy-induced hypertension. Choices A, B, and D are incorrect because 4+ reflexes, urinary output, and body temperature are not direct indicators of achieving a therapeutic level of magnesium sulfate for controlling PIH symptoms.
