Commercial formulas contain 20 calories per ounce. A 1-day-old infant's weight in the morning was 8 lb and he was fed 45 mL at 2 a.m., 5:30 a.m., 8 a.m., 11 a.m., 2 p.m., 4:30 p.m., 8 p.m., and 10:30 p.m. What is the total amount of calories the infant received today?
- A. calories.
Correct Answer: B
Rationale: The infant was fed 45 mL 8 times, totaling 360 mL. Since 1 oz ≈ 30 mL, 360 mL ÷ 30 mL/oz = 12 oz. At 20 calories per ounce, 12 oz × 20 cal/oz = 240 calories.

Which of the following would the nurse include in the teaching plan for a 16-year-old primigravid client in early labor concerning active relaxation techniques to help her cope with pain?
- A. Relaxing uninvolved body muscles during uterine contractions.
- B. Practicing being in a deep, meditative, sleeplike state.
- C. Focusing on an object in the room during the contractions.
- D. Breathing rapidly and deeply between contractions.
Correct Answer: A
Rationale: Active relaxation involves consciously relaxing uninvolved muscles (e.g., face, arms) during contractions to conserve energy and reduce tension, aiding pain management. Meditation is less practical during active labor, focusing on an object is a distraction technique, and rapid breathing between contractions may cause hyperventilation.
After instructing a multigravid client at 10 weeks' gestation diagnosed with chronic hypertension about the need for frequent prenatal visits, the nurse determines that the instructions have been successful when the client states which of the following?
- A. "I may develop hyperthyroidism because of my high blood pressure."
- B. "I need close monitoring because I may have a small-for-gestational-age infant."
- C. "It's possible that I will have excess amniotic fluid and may need a cesarean section."
- D. "I may develop placenta accreta, so I need to keep my clinic appointments."
Correct Answer: B
Rationale: Chronic hypertension increases the risk of having a small-for-gestational-age infant.
The cervix of a primigravid client in active labor who received epidural anesthesia 4 hours ago is now completely dilated, and the client is ready to begin pushing. Before the client begins to push, the nurse should assess:
- A. Fetal heart rate variability.
- B. Cervical dilation again.
- C. Status of membranes.
- D. Bladder status.
Correct Answer: D
Rationale: A full bladder can impede fetal descent and increase discomfort during pushing. Assessing bladder status (and catheterizing if needed) is critical before pushing begins. Fetal heart rate, dilation, and membrane status should already be monitored but are not the priority at this moment.
A nurse is teaching a client about the fertility awareness method. Which of the following instructions should the nurse include?
- A. Track basal body temperature and cervical mucus daily.
- B. Avoid intercourse throughout the entire menstrual cycle.
- C. Use this method if you have irregular periods.
- D. Monitor ovulation with a home pregnancy test.
Correct Answer: A
Rationale: Tracking basal body temperature and cervical mucus daily is essential for the fertility awareness method to identify fertile days. Intercourse is avoided only during fertile periods, the method is less reliable with irregular periods, and pregnancy tests do not monitor ovulation.
A client has obtained Plan B (levonorgestrel 0.75 mg, 2 tablets) as emergency contraception. After unprotected intercourse, the client calls the clinic to ask questions about taking the contraceptives. The nurse realizes the client needs further explanation when she makes which of the following responses?
- A. I can wait 3 to 4 days after intercourse to start taking these to prevent pregnancy.
- B. My boyfriend can buy Plan B from the pharmacy if he is over 18 years old.
- C. The birth control works by preventing ovulation or fertilization of the egg.
- D. I can be discussed and have breast tenderness or a headache after using the contraceptive.
Correct Answer: A
Rationale: Plan B is most effective when taken within 72 hours of unprotected intercourse, ideally as soon as possible. Waiting 3 to 4 days reduces its efficacy, indicating a need for further explanation.
