1. A nurse is caring for a client who is at 36 weeks of gestation and who has a
suspected placenta previa. Which of the following findings support this
diagnosis?
A. Painless red vaginal bleeding
Rationale: Placenta previa is a condition of pregnancy when the placenta
implants in the lower part of the uterus, partly or completely
obstructing the cervical os (outlet to the vagina). Bright red,
painless vaginal bleeding occurs in the second and third trimester.
B. Increasing abdominal pain with a nonrelaxed uterus
Rationale: Abruptio placenta is separation of the placenta from the site of
uterine implantation before delivery of the fetus. When the placenta
separates prematurely, there is internal bleeding, which is painful,
and the uterus is nonrelaxed or becomes rigid as the separation
advances.
C. Abdominal pain with scant red vaginal bleeding
Rationale: Placenta previa involves minimal to severe bright red vaginal
bleeding in the absence of abdominal pain.
D. Intermittent abdominal pain following passage of bloody mucus
Rationale: Intermittent abdominal pain following passage of bloody mucus
is a description of normal labor. The passage of bloody mucus
represents the loss of the cervical mucous plug, also referred to
as the "bloody show."




2. A nurse is caring for a client who is 1 hr postpartum and observes a large

amount of lochia rubra and several small clots on the client's perineal pad. The
fundus is midline and firm at the umbilicus. Which of the following actions should
the nurse take?
A. Document the findings and continue to monitor the client.
Rationale: These are expected findings. At 1 hr postpartum, lochia rubra
should be intermittent and associated with uterine contractions.
The volume of lochia resembles that of a heavy menstrual period.
Small clots are common. The nurse should document the findings
and continue to monitor the client.
B. Notify the client’s provider.
Rationale: These are expected findings, so there is no need to notify the
provider.
C. Increase the frequency of fundal massage.
Rationale: These are expected findings and the fundus is already firm.
Increasing the frequency of fundal massage is not indicated at this
time.
D. Encourage the client to empty her bladder.
Rationale: These are expected findings, and the fundus is firm at the midline.
If the fundus was deviated, this would be an indication of a
distended bladder and the client should be encouraged to void to
prevent uterine atony.

3. A nurse is caring for a newborn immediately following birth. After assuring a
patent airway, what is the priority nursing action?
A. Administer vitamin K.
Rationale: Administration of vitamin K is important, but it can be delayed
until the newborn is held by the mother and is breastfed. There is
another, more important nursing action.
B. Dry the skin.
Rationale: The newborn should be thoroughly dried, covered with a warm
blanket, placed on the mother’s abdomen, and a cap applied to the
newborn’s head to prevent cold stress. The newborn responds to
the cooler environment by increasing his respiratory rate, which
can lead to respiratory distress. Based on Maslow’s hierarchy of
needs, this is the most important nursing action after securing the
airway.
C. Administer eye prophylaxis.
Rationale: Administration of eye prophylaxis should occur within the first
hour after birth. There is another, more important nursing action.
D. Place an identification bracelet.
Rationale: Correct identification of the newborn is important, but it can be
delayed, as long as it is completed prior to the mother and
newborn leaving the delivery room. There is another, more
important nursing action.




4. A nurse in a prenatal clinic is caring for a client who is at 7 weeks of gestation.
The client reports urinary frequency and asks if this will continue until delivery.
Which of the following responses should the nurse make?
A. "It's a minor inconvenience, which you should ignore."
Rationale: This is a nontherapeutic response that disregards the client’s
concern and offers unwarranted reassurance.

B. "In most cases it only lasts until the 12th week, but it will continue if you have
poor bladder tone."
Rationale: The presence or absence of bladder tone has no bearing on
urinary frequency during pregnancy.
C. "There is no way to predict how long it will last in each individual client."
Rationale: This is a nontherapeutic response that does not provide
appropriate information to the client.
D. "It occurs during the first trimester and near the end of the pregnancy."
Rationale: Urinary frequency is due to increased bladder sensitivity during
the first trimester and recurs near the end of the pregnancy as the
enlarging uterus places pressure on the bladder.
