1. 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.
2. A 25-year-old gravida 3, para 2 client gave birth to a 9-pound, 7-ounce boy 4 hours ago after augmentation of labor with oxytocin (Pitocin). She presses her call light and asks for her nurse right away, stating 'I’m bleeding a lot.' What is the most likely cause of postpartum hemorrhage in this client?
- A. Retained placental fragments.
- B. Unrepaired vaginal lacerations.
- C. Uterine atony.
- D. Puerperal infection.
Correct answer: C
Rationale: Uterine atony is the most likely cause of bleeding 4 hours after delivery, especially after delivering a macrosomic infant and augmenting labor with oxytocin. Uterine atony is characterized by the inability of the uterine muscles to contract effectively after childbirth, leading to excessive bleeding. The other options, such as retained placental fragments (A), unrepaired vaginal lacerations (B), and puerperal infection (D), are less likely causes of postpartum hemorrhage in this scenario. Retained placental fragments can cause bleeding, but this typically presents earlier than 4 hours postpartum. Unrepaired vaginal lacerations would likely be evident sooner and not typically result in significant bleeding. Puerperal infection is not a common cause of immediate postpartum hemorrhage unless there are other signs of infection present.
3. When reviewing the electronic medical record of a postpartum client, which of the following factors places the client at risk for infection?
- A. Meconium-stained amniotic fluid
- B. Placenta previa
- C. Midline episiotomy
- D. Gestational hypertension
Correct answer: C
Rationale: The correct answer is C: Midline episiotomy. An episiotomy is a surgical incision made during childbirth to enlarge the vaginal opening. This procedure increases the risk of infection in the postpartum period due to the incision site being a potential entry point for pathogens. Meconium-stained amniotic fluid (choice A) is a risk factor for fetal distress but does not directly increase the mother's risk of infection. Placenta previa (choice B) is a condition where the placenta partially or completely covers the cervix, leading to potential bleeding issues but not necessarily an increased risk of infection. Gestational hypertension (choice D) is a hypertensive disorder that affects some pregnant women but is not directly associated with an increased risk of infection in the postpartum period.
4. Four clients at full term present to the labor and delivery unit at the same time. Which client should a nurse assess first?
- A. Multipara with contractions occurring every three minutes
- B. Multipara scheduled for non-stress test and biophysical profile
- C. Primipara with vaginal show and leaking membranes
- D. Primipara with burning on urination and urinary frequency
Correct answer: C
Rationale: A primipara with vaginal show and leaking membranes requires immediate assessment as she may be in active labor or at risk of infection. The vaginal show and leaking membranes suggest potential rupture of membranes and the start of labor. Assessing her first ensures prompt management and monitoring. The other options, while important, do not indicate immediate or emergent needs. Contractions every three minutes in a multipara can be managed with ongoing monitoring; non-stress tests and biophysical profiles can be scheduled and are not acute needs. Burning on urination and urinary frequency in a primipara may indicate a urinary tract infection, which is important but not as urgent as assessing for active labor or rupture of membranes.
5. Which of the following statements is true of menstruation?
- A. During this time, the endometrium is shed.
- B. During this time, an unfertilized egg is discharged.
- C. During this time, a female can engage in sexual activity with her partner.
- D. During this time, a fertilized egg implants in the uterine lining.
Correct answer: B
Rationale: The correct statement regarding menstruation is that during this time, an unfertilized egg is discharged along with the shedding of the uterine lining. Choice A is incorrect because the endometrium is shed during menstruation. Choice C is incorrect as menstruation does not prevent a female from engaging in sexual activity with her partner. Choice D is incorrect as a fertilized egg does not undergo mitosis during menstruation but rather implants in the uterine lining for further development.
