HESI Maternity 55 Questions
1. Once the testes have developed in the embryo, they begin to produce male sex hormones, or _____.
- A. androgens
- B. genotypes
- C. blastocysts
- D. teratogens
Correct answer: A
Rationale: Androgens are male sex hormones, such as testosterone, produced by the testes after they have developed in the embryo. Androgens are responsible for the development of male secondary sexual characteristics. Genotypes refer to an individual's genetic makeup, not hormones. Blastocysts are early stage embryos, not male sex hormones. Teratogens are substances that can interfere with fetal development, not male sex hormones produced by the testes.
2. In the context of an average ejaculation, which of the following statements is true about sperm?
- A. The average count of sperm in the ejaculate is 2.5 billion.
- B. Sperm in the ejaculate find the ovum by following the current of the fluid coming from the cervix.
- C. Only 1 in 1,000 sperm in the ejaculate will ever approach an ovum.
- D. Most of the sperm in the ejaculate move about in a random pattern in the vagina.
Correct answer: C
Rationale: Out of millions of sperm released during ejaculation, only a small fraction, about 1 in 1,000, will approach the ovum. This statement is true as sperm face many obstacles and challenges on their journey to reach and fertilize an ovum. Choice A is incorrect because the average count of sperm in an ejaculate is typically in the millions, not billions. Choice B is incorrect as sperm do not find the ovum by following the current of fluid; they navigate using other mechanisms. Choice D is incorrect because while some sperm may move randomly in the vagina, the ones that approach the ovum do so through a more purposeful and directed movement.
3. A client is 4 hours postpartum and is experiencing hypovolemic shock. Which of the following actions should the nurse take?
- A. Administer indomethacin
- B. Insert a second 22-gauge IV catheter.
- C. Insert an indwelling urinary catheter.
- D. Administer oxygen at 4L/min via nasal cannula.
Correct answer: D
Rationale: In hypovolemic shock, there is decreased oxygen delivery to tissues. Administering oxygen at 4L/min via nasal cannula can help improve oxygenation and support tissue perfusion. Indomethacin (Choice A) is a nonsteroidal anti-inflammatory drug and is not indicated in the management of hypovolemic shock. Inserting a second 22-gauge IV catheter (Choice B) may be necessary for fluid resuscitation, but oxygen administration takes precedence. Inserting an indwelling urinary catheter (Choice C) may be considered for monitoring urinary output, but it is not the priority action in managing hypovolemic shock.
4. A pregnant client mentions in her history that she changes the cat's litter box daily. Which test should the nurse anticipate the healthcare provider to prescribe?
- A. Biophysical profile
- B. Fern test
- C. Amniocentesis
- D. TORCH screening
Correct answer: D
Rationale: The correct answer is D, TORCH screening. TORCH screening is done to detect infections such as toxoplasmosis, which can be contracted from handling cat litter and is harmful during pregnancy. Biophysical profile (choice A) is a prenatal ultrasound evaluation. Fern test (choice B) is used to assess for amniotic fluid leakage. Amniocentesis (choice C) involves taking a sample of amniotic fluid to test for genetic abnormalities and certain infections, not specifically related to toxoplasmosis from cat litter.
5. What additional assessment is required for the postoperative care of a pregnant woman who undergoes abdominal surgery for appendicitis?
- A. Intake and output (I&O) and intravenous (IV) site.
- B. Signs and symptoms of infection.
- C. Vital signs and incision.
- D. Fetal heart rate (FHR) and uterine activity.
Correct answer: D
Rationale: The correct additional assessment for postoperative care of a pregnant woman requiring abdominal surgery for appendicitis is monitoring the fetal heart rate (FHR) and uterine activity. This is crucial due to the presence of the fetus. Continuous fetal and uterine monitoring should be prioritized to ensure the well-being of both the mother and the baby. While assessing I&O levels and the IV site are common postoperative care procedures, they are not specific to the unique needs of a pregnant woman. Evaluating for signs and symptoms of infection is important for any postoperative patient but is not the additional assessment required specifically for a pregnant woman in this scenario. Routine vital signs and incision evaluation are standard components of postoperative care but do not address the specific needs related to the fetus and the uterus in this case.
