HESI Focus on Maternity Exam
1. A nurse on a labor and delivery unit is providing teaching to a client who plans to use hypnosis to control labor pain. Which of the following information should the nurse include?
- A. Focusing on controlling body functions
- B. Synchronized breathing is often helpful during hypnosis
- C. Hypnosis can be beneficial if practiced during the prenatal period
- D. Hypnosis is ineffective for controlling pain associated with labor
Correct answer: C
Rationale: Hypnosis can be an effective method of pain control during labor, especially if practiced during the prenatal period. Choice A is not specific to hypnosis and may not be directly related. Choice B is not essential for hypnosis and may not always be required. Choice D is incorrect as hypnosis has been shown to be beneficial for managing labor pain when done correctly, making it an inappropriate option to include in the teaching.
2. A nurse on the postpartum unit is caring for four clients. For which of the following clients should the nurse notify the provider?
- A. A client with a urinary output of 300 ml in 8 hours
- B. A client reporting abdominal cramping during breastfeeding
- C. A client receiving magnesium sulfate with absent deep tendon reflexes
- D. A client reporting lochia rubra requiring changing perineal pads every 3 hours
Correct answer: C
Rationale: The correct answer is C because in a client receiving magnesium sulfate, absent deep tendon reflexes can indicate magnesium toxicity, which requires immediate intervention to prevent serious complications. Choices A, B, and D are common postpartum occurrences that do not typically warrant immediate provider notification. A urinary output of 300 ml in 8 hours, abdominal cramping during breastfeeding, and frequent changing of perineal pads due to lochia rubra are within the expected range of postpartum recovery and do not indicate an urgent need for provider notification.
3. Chromosomes contain thousands of segments called:
- A. nuclei.
- B. nodes.
- C. capillaries.
- D. genes.
Correct answer: D
Rationale: Chromosomes are structures composed of DNA and genes. Genes are the functional segments within chromosomes that encode specific traits and characteristics. The other choices ('nuclei,' 'nodes,' 'capillaries') do not accurately describe the segments found within chromosomes and are unrelated to their structure or function.
4. A client at 27 weeks of gestation with preeclampsia is being assessed by a nurse. Which of the following findings should the nurse report to the provider?
- A. Urine protein concentration of 200 mg/24 hr.
- B. Creatinine level of 0.8 mg/dL
- C. Hemoglobin level of 14.8 g/dL
- D. Platelet count of 60,000/mm3
Correct answer: D
Rationale: A platelet count of 60,000/mm3 is significantly low and can indicate HELLP syndrome, a severe complication of preeclampsia that involves hemolysis, elevated liver enzymes, and low platelet count. HELLP syndrome requires prompt medical intervention to prevent serious maternal and fetal complications. The other findings listed are within normal limits or not directly related to the severe condition associated with HELLP syndrome.
5. A nurse is planning to teach a group of clients who are breastfeeding after returning to work. Which of the following instructions should the nurse include in the teaching?
- A. “Thawed breast milk can be refrigerated for up to 24 hours.â€
- B. “Breast milk can be stored in a deep freezer for 12 months.â€
- C. “Breast milk can be stored at room temperature for up to 4 hours.â€
- D. “Thawed breast milk that is unused cannot be refrozen.â€
Correct answer: B
Rationale: The correct answer is B: “Breast milk can be stored in a deep freezer for 12 months.†This instruction is important for mothers returning to work to ensure a long-term storage option for breast milk. Choice A is incorrect because thawed breast milk should be used within 24 hours if stored in the refrigerator. Choice C is incorrect as breast milk can be kept at room temperature for only up to 4 hours. Choice D is incorrect as thawed breast milk that is unused should not be refrozen due to safety concerns.
