HESI Maternity 55 Questions
1. According to a survey by Adhikari and Liu in the year 2013, at birth, women have:
- A. close to 100,000 ova.
- B. around 300,000 to 400,000 ova.
- C. around 100 to 200 ova.
- D. only 500 ova.
Correct answer: B
Rationale: Women are born with approximately 300,000 to 400,000 ova, which gradually decrease in number as they age. Choice A ('close to 100,000 ova.') is incorrect as the actual number is much higher. Choice C ('around 100 to 200 ova.') is incorrect as it underestimates the quantity significantly. Choice D ('only 500 ova.') is incorrect as it greatly underestimates the number of ova present at birth.
2. The nurse has received a report regarding a client in labor. The woman’s last vaginal examination was recorded as 3 cm, 30%, and –2. What is the nurse’s interpretation of this assessment?
- A. Cervix is effaced 3 cm and dilated 30%; the presenting part is 2 cm above the ischial spines.
- B. Cervix is dilated 3 cm and effaced 30%; the presenting part is 2 cm above the ischial spines.
- C. Cervix is effaced 3 cm and dilated 30%; the presenting part is 2 cm below the ischial spines.
- D. Cervix is dilated 3 cm and effaced 30%; the presenting part is 2 cm below the ischial spines.
Correct answer: B
Rationale: The correct interpretation of the assessment provided is that the cervix is dilated 3 cm and effaced 30%; the presenting part is 2 cm above the ischial spines. In the given assessment, the measurements are ordered as dilation, effacement, and station. Choice A is incorrect as it wrongly places the presenting part below the ischial spines. Choice C is incorrect because it places the presenting part below the ischial spines. Choice D is also incorrect as it incorrectly states that the presenting part is below the ischial spines, even though it correctly mentions the dilation and effacement of the cervix.
3. 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.
4. A nurse is developing an educational program about hemolytic diseases in newborns for a group of newly licensed nurses. Which of the following genetic information should the nurse include in the program as a cause of hemolytic disease?
- A. The mother is Rh positive, and the father is Rh negative
- B. The mother is Rh negative, and the father is Rh positive
- C. The mother and the father are both Rh positive
- D. The mother and the father are both Rh negative
Correct answer: B
Rationale: The correct answer is B: 'The mother is Rh negative, and the father is Rh positive.' Hemolytic disease of the newborn occurs when an Rh-negative mother carries an Rh-positive fetus, leading to Rh incompatibility. In this scenario, the mother produces antibodies against the Rh antigen present in the fetus, which can result in hemolysis of the fetal red blood cells. Choices A, C, and D do not describe the Rh incompatibility that leads to hemolytic disease in newborns. Therefore, they are incorrect.
5. Which of the following statements is true of mutations?
- A. Mutations can only occur by chance.
- B. Mutations produce sperm and ova cells.
- C. Mutations occur through radiation or other environmental influences.
- D. Mutations help adenine combine with guanine to form the single spiral structure of DNA.
Correct answer: C
Rationale: The correct answer is C. Mutations can occur due to environmental influences such as radiation, chemicals, or other external factors, leading to changes in the DNA sequence. Choice A is incorrect because mutations can also occur due to errors in DNA replication, not solely by chance. Choice B is incorrect as mutations affect the DNA sequence itself, not the production of specific cells. Choice D is incorrect because mutations involve changes in the DNA sequence and do not specifically involve the formation of the DNA structure.
