HESI Focus on Maternity Exam
1. A newborn with a respiratory rate of 40 breaths per minute at one minute after birth is demonstrating cyanosis of the hands and feet. What action should a nurse take?
- A. Assess bowel sounds.
- B. Continue to monitor.
- C. Assist with intubation.
- D. Rub the infant's back.
Correct answer: B
Rationale: Cyanosis of the hands and feet, known as acrocyanosis, is common in newborns shortly after birth and usually resolves on its own. It is not indicative of a need for immediate intervention. Therefore, the appropriate action is to continue monitoring the newborn's condition. Assessing bowel sounds (Choice A) is not relevant to the presenting issue of cyanosis and respiratory rate. Assisting with intubation (Choice C) is an invasive procedure that is not warranted based on the information provided. Rubbing the infant's back (Choice D) is not necessary for acrocyanosis and could potentially disturb the newborn.
2. 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.
3. 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.
4. What should be the primary focus of nursing care in the transitional phase of labor for a client who anticipates an unmedicated delivery?
- A. Assessing the strength of uterine contractions
- B. Re-evaluating the need for medication
- C. Reminding her to push 3 times with each contraction
- D. Assisting her to maintain control
Correct answer: D
Rationale: During the transitional phase of labor, which is the most intense phase, the primary focus of nursing care for a client who anticipates an unmedicated delivery should be assisting her to maintain control. This is essential to help her manage the intense pain and anxiety associated with this phase without the use of medication. Assessing the strength of uterine contractions (Choice A) is important but not the primary focus during the transitional phase. Re-evaluating the need for medication (Choice B) is not applicable as the client anticipates an unmedicated delivery. Reminding her to push 3 times with each contraction (Choice C) is more related to the pushing stage of labor and not the transitional phase.
5. When both of the alleles for a trait, such as hair color, are the same, the person is said to be _____ for that trait.
- A. monozygous
- B. dizygous
- C. homozygous
- D. hemizygous
Correct answer: C
Rationale: A person is homozygous for a trait when they have two identical alleles for that trait. In this case, both alleles are the same, indicating a homozygous genotype. Choice A, 'monozygous,' is incorrect as it refers to identical twins originating from a single fertilized egg. Choice B, 'dizygous,' is also incorrect as it refers to fraternal twins or individuals that develop from two separate fertilized eggs. Choice D, 'hemizygous,' is incorrect because it describes a genetic condition where only one allele is present in a diploid organism, typically related to genes on the sex chromosomes.
