NUR325-B-Nursing Services Childbearing- Final Exam B (CBU )

The correct answer is C: It may take months for sperm in the semen to be eliminated.

Explanation:

C. It may take months for sperm in the semen to be eliminated: After a vasectomy, sperm can still be present in the semen for some time before the body completely clears them. Typically, it may take several weeks to months (often around 3 months) for the sperm to be eliminated after the procedure. During this time, the man must continue using contraception until a follow-up semen analysis confirms that no sperm are present. This is an important point to explain to the client, as they may assume immediate contraception effectiveness, which is not the case.

Why the Other Options Are Incorrect:

A. Contraceptive is 100% effective: While vasectomy is highly effective, it is not 100% effective. The failure rate is very low (approximately 1 in 1000 men), but it is important to clarify to clients that no contraceptive method is guaranteed to be 100% effective. The client should understand the slight risk of failure and the importance of follow-up testing to ensure the procedure’s success.

B. It can be performed under general anesthesia: Vasectomy is typically performed under local anesthesia, not general anesthesia. The procedure is minimally invasive and does not require the patient to be fully sedated. General anesthesia is unnecessary, and this point would be an incorrect explanation of the procedure.

D. Voluntary reversal is impossible: While vasectomy reversal is more complicated and not always successful, it is not impossible. In some cases, vasectomy reversal can be performed successfully, though the success rate declines over time since the procedure. It's important to explain to the client that although reversal is difficult and not always guaranteed, it is still possible under certain conditions.

Summary:

The correct explanation is C. It may take months for sperm in the semen to be eliminated. This is an important detail when discussing the timeline for vasectomy effectiveness, as the sperm will still be present in the semen for some time after the procedure. The other options are incorrect because vasectomy is not 100% effective, is generally performed under local anesthesia, and can sometimes be reversed, though it is not guaranteed.

The correct answer is D: I will have a one-hour glucola test (glucose tolerance test) to screen for gestational diabetes during the second trimester.

Explanation:

This statement is correct because the one-hour glucose tolerance test (glucola test) is the standard screening method for gestational diabetes during the second trimester (24-28 weeks of pregnancy). If the results are elevated, a follow-up three-hour glucose tolerance test (GTT) is performed to confirm the diagnosis.

Why the Other Options Are Incorrect:

A. I will get my A1C checked every visit.

This is incorrect because HbA1c is not a routine test for diagnosing gestational diabetes. HbA1c reflects long-term glucose control (over approximately three months) and is more commonly used for diagnosing pre-existing diabetes rather than gestational diabetes.

B. A fasting glucose done in the first trimester of pregnancy will show if I have gestational diabetes.

This is incorrect because a fasting glucose test in the first trimester is used to identify pre-existing diabetes, not gestational diabetes. Gestational diabetes develops later in pregnancy (typically after 20 weeks) due to insulin resistance caused by placental hormones.

C. All women are tested in the second trimester with a three-hour glucose tolerance test to determine if they have gestational diabetes.

This is incorrect because not all women undergo the three-hour glucose tolerance test. Instead, the one-hour glucola test is done first, and only women with elevated results on the one-hour test undergo the three-hour test for confirmation.

Summary:

The correct answer is D because the one-hour glucola test is the standard screening test for gestational diabetes in the second trimester. The other options are incorrect because they either misrepresent the timing or type of tests used for diagnosing gestational diabetes.

The correct answers are A: Perform airway suction, B. Place infant under radiant warmer, D. Assess respiratory function.

Explanation:

This newborn is exhibiting signs of distress, including bradycardia, cyanosis, and unresponsiveness, which are typical of neonatal resuscitation needs. Immediate intervention is necessary to stabilize the infant and assess the cause of the distress.

A. Perform airway suction: Suctioning the airway is crucial if the newborn has respiratory distress, particularly if the airway is obstructed by mucus or amniotic fluid. Clearing the airway can help improve oxygenation and resolve some of the symptoms.

B. Place infant under radiant warmer: Newborns are at risk of hypothermia, especially if they are unresponsive and experiencing distress. Placing the infant under a radiant warmer helps maintain their body temperature, which is critical for stabilizing their condition.

D. Assess respiratory function: Assessing the respiratory function is essential. The newborn’s respiratory rate, effort, and oxygen saturation should be evaluated to determine the severity of the condition and guide further interventions, such as providing oxygen or initiating resuscitation measures.

Why the Other Options Are Incorrect:

C. Administer IV fluids: Administering IV fluids is not the first step in responding to neonatal distress unless there are signs of dehydration, blood loss, or shock. In this scenario, the focus is on stabilizing the infant’s airway, breathing, and circulation, rather than immediate fluid administration.

E. Encourage early breastfeeding: Early breastfeeding is important for newborns, but it is not a priority in this situation. The infant needs immediate stabilization before initiating breastfeeding. Once the newborn is stable, breastfeeding can be encouraged.

F. Administer calcium gluconate: Calcium gluconate is typically used in specific cases, such as hypocalcemia, which is not indicated by the symptoms in this scenario. The priority in this case is stabilization and resuscitation, not the administration of calcium gluconate.

Summary:

In the case of a newborn exhibiting bradycardia, cyanosis, and unresponsiveness, the nurse should prioritize performing airway suction, placing the infant under a radiant warmer, and assessing respiratory function. Other interventions like administering IV fluids, encouraging breastfeeding, or administering calcium gluconate are not immediate priorities in this situation.

The correct answer is A: prevent alveoli from collapsing on expiration.

Explanation for the correct answer:

Surfactant is a substance produced in the fetal lungs that plays a crucial role in maintaining lung function after birth. Its primary purpose is to reduce surface tension in the alveoli (tiny air sacs in the lungs), which prevents the alveoli from collapsing during exhalation. This allows for proper gas exchange and ensures that the lungs can inflate fully with each breath. Without sufficient surfactant, the alveoli would collapse, making breathing difficult and leading to respiratory distress syndrome (RDS) in premature infants.

Why the other options are incorrect:

B) Increase lung resistance on inspiration: This is incorrect. Surfactant actually decreases lung resistance, facilitating easier inspiration. By reducing surface tension, surfactant helps the lungs to expand more easily and reduces the work required for breathing.

C) Encourage immunologic competence of lung tissue: This is incorrect. While surfactant plays a role in lung function, it is not primarily involved in the development of immunologic competence. The immune system in the lungs develops independently from surfactant production, and surfactant is more involved in respiratory mechanics than in immune function.

D) Promote maturation of lung alveoli: This is partially true, but it is not the main function of surfactant. Surfactant helps the alveoli function once they are mature, but it does not directly promote their maturation. Alveolar maturation is a process that occurs earlier in fetal development, while surfactant production begins later, typically around 24-28 weeks of gestation.

Summary: Surfactant’s primary purpose is to prevent alveolar collapse on expiration by reducing surface tension in the lungs, ensuring efficient gas exchange and proper lung function. This is critical for newborns, especially premature infants, who may not have sufficient surfactant production.

The correct answer is C: Postpartum hemorrhage and urinary tract infection.

Explanation:

In the postpartum period, frequent urination is crucial to prevent bladder distension and urinary retention, as both can cause serious complications. An overdistended bladder may prevent the uterus from contracting effectively, which increases the risk of postpartum hemorrhage (PPH). Additionally, urinary stasis (when urine remains in the bladder) provides a breeding ground for bacteria, increasing the likelihood of developing a urinary tract infection (UTI).

Why the other options are incorrect:

A. Postpartum hemorrhage and hematoma formation:

While postpartum hemorrhage is a valid concern, bladder distension does not directly cause hematoma formation. Hematomas usually result from trauma during delivery or improper suturing of episiotomies or lacerations, not from urinary retention.

B. Fever and foul-smelling lochia:

Fever and foul-smelling lochia are signs of endometritis (uterine infection), which is not directly caused by urinary retention or bladder distension. However, poor bladder emptying can contribute to infection risk over time but does not typically lead to these specific symptoms on its own.

D. Urinary tract infection and uterine involution:

While urinary tract infections are a risk, uterine involution refers to the uterus returning to its pre-pregnancy size. Bladder distension can impede uterine contractions, but it does not prevent involution altogether.

Summary:

The most accurate answer is C. Postpartum hemorrhage and urinary tract infection because bladder overdistension can prevent proper uterine contraction, leading to PPH, and urinary retention increases the risk of UTIs due to bacterial growth. Frequent urination helps prevent these complications during the postpartum period.

The correct answer is A: Ectopic pregnancy.

Explanation:

Damage to the fallopian tube, such as malformation or scarring, increases the risk of ectopic pregnancy. The fallopian tubes are responsible for transporting the fertilized egg to the uterus. If scarring narrows or blocks the tube, the fertilized egg may implant in the fallopian tube instead of reaching the uterus, leading to an ectopic pregnancy. This condition is a medical emergency because the growing embryo can rupture the tube, causing severe bleeding and life-threatening complications.

Why the Other Options Are Incorrect:

B. Urinary tract infections:

Incorrect. Fallopian tube scarring does not increase the risk of urinary tract infections (UTIs), as UTIs are related to the urinary system (kidneys, bladder, urethra) rather than the reproductive system.

C. A decrease in estrogen levels:

Incorrect. Damage to the fallopian tubes does not directly impact estrogen production, which is primarily regulated by the ovaries.

D. Early menopause:

Incorrect. Early menopause is primarily caused by ovarian failure, genetic factors, autoimmune diseases, or medical treatments (e.g., chemotherapy, radiation), not by fallopian tube abnormalities.

Summary:

A client with fallopian tube scarring is at high risk for an ectopic pregnancy due to the potential blockage or narrowing of the tube, preventing normal implantation in the uterus.

The correct answers are:

A. Brethine (Terbutaline)

D. Betamethasone

F. IV Fluids

Explanation:

This patient is at 34 weeks gestation and experiencing regular contractions every 3–5 minutes with a cervical exam of 2 cm/70%/-3. Since she is preterm, the goal is to stop or slow preterm labor and enhance fetal lung maturity.

A. Brethine (Terbutaline):

Correct. Terbutaline is a tocolytic used to temporarily stop preterm labor. It works as a beta-adrenergic agonist, relaxing the uterine muscles to delay delivery. Since the patient is only 34 weeks, stopping contractions can provide time for corticosteroids to improve fetal lung maturity.

D. Betamethasone:

Correct. Betamethasone is a corticosteroid given to accelerate fetal lung development by stimulating surfactant production. It is indicated in pregnancies between 24–34 weeks gestation when preterm birth is a risk. Administering two doses, 24 hours apart, can significantly reduce neonatal respiratory distress syndrome (RDS).

F. IV Fluids:

Correct. Hydration can help reduce uterine irritability and contractions. Dehydration can cause an increase in oxytocin release, leading to contractions. Administering IV fluids, such as Lactated Ringer’s or normal saline, can sometimes slow contractions.

Why the Other Options Are Incorrect:

B. Pitocin 20 u in 500cc RL to run at 125cc per hour:

Incorrect. Pitocin (oxytocin) is used to induce or augment labor, not to stop preterm contractions. Since this patient is preterm at 34 weeks, inducing labor is not the priority unless there is a maternal or fetal indication (such as infection or distress).

C. Misoprostol (Cytotec):

Incorrect. Misoprostol is a prostaglandin used to induce labor or ripen the cervix. Since the goal is to stop preterm labor, administering a labor-inducing medication would be contraindicated.

E. Oxytocin (Pitocin):

Incorrect. As mentioned above, oxytocin stimulates uterine contractions and is used in labor induction or augmentation. Since this patient is preterm, promoting labor progression is not the goal.

Summary:

The best recommendations for this 34-week pregnant patient in preterm labor are Brethine (Terbutaline) to stop contractions, Betamethasone to mature fetal lungs, and IV fluids to reduce uterine irritability. Labor-inducing agents like Pitocin and Misoprostol are inappropriate, as the priority is prolonging pregnancy to improve neonatal outcomes.

The correct answer is C: With your hand, during the vaginal exam, keep the fetal head from compressing the cord.

Explanation:

C. With your hand, during the vaginal exam, keep the fetal head from compressing the cord:

When cord prolapse is detected, the immediate priority is to relieve pressure on the prolapsed umbilical cord and prevent fetal hypoxia due to cord compression. The nurse should gently push the fetal head off the cord to avoid compressing the blood vessels in the umbilical cord, which could restrict blood flow to the fetus. This should be done immediately to reduce the risk of fetal distress.

While performing this action, the nurse should keep the cord off the presenting part (usually the head) and stay with the patient until emergency measures can be taken (like preparing for an emergency C-section).

Why the Other Options Are Incorrect:

A. Place the client in a knee chest position:

While the knee-chest position can help relieve some of the pressure from the umbilical cord by changing the position of the fetus, the priority is to immediately relieve the pressure on the cord. The correct action is to manually push the fetal head off the cord, not just rely on positioning. Therefore, while the knee-chest position may be helpful in some cases, it's secondary to manually preventing cord compression.

B. Place 8L of O2 by mask, on the patient:

Administering oxygen to the mother can help increase oxygenation to the fetus, but it is not the first priority. The first priority is to prevent cord compression by physically relieving the pressure on the cord. Oxygen may be administered once the cord compression is relieved, but it is not the immediate priority.

D. Obtain a consent for an immediate C-Section:

While an emergency C-section is often required for a cord prolapse, the immediate priority is to relieve the pressure on the cord to preserve fetal oxygenation. The decision for a C-section will be made after the initial interventions to relieve the prolapse. Obtaining consent can happen quickly, but it is not the first step in managing this emergency.

Summary:

The immediate priority when cord prolapse is detected is to relieve pressure on the umbilical cord to prevent fetal compromise. This is done by manually pushing the fetal head off the cord during the vaginal exam (option C). Other interventions, such as positioning the mother or administering oxygen, are supportive measures but not as critical as managing the prolapse directly.

The correct answer is C: Consuming a nutritional diet with 300 kcal more than normal.

Explanation:

Before pregnancy (during preconception care), a woman does not need to increase her caloric intake by 300 kcal per day. This additional calorie intake is only required during pregnancy, particularly in the second and third trimesters to support fetal growth. During preconception, the focus is on maintaining a balanced, nutrient-rich diet without increasing overall caloric intake unless the woman is underweight or has specific medical needs.

Why the other options are correct:

A. Taking prenatal vitamins with 400 mcg of folic acid:

Folic acid is crucial during the preconception period because it helps prevent neural tube defects (such as spina bifida and anencephaly). Women planning pregnancy should take 400 mcg daily at least one month before conception and continue during early pregnancy.

B. Normalizing HgA1c levels, if diabetic, prior to conception:

For women with diabetes, achieving a normal hemoglobin A1c (HgA1c) level before conception reduces the risk of birth defects, miscarriage, and other complications. Poor glucose control during early pregnancy increases risks to both the mother and the fetus.

D. Going to the dentist for a routine check-up and cleaning:

Good oral health is an essential part of preconception care. Gum disease (periodontitis) is linked to preterm birth and low birth weight. Routine dental exams and cleanings help prevent oral infections that may affect pregnancy outcomes.

Summary:

The nurse would not include "consuming 300 kcal more than normal" in preconception teaching because increased caloric intake is only necessary once pregnancy occurs. Key components of preconception care include taking folic acid, managing chronic conditions, and ensuring oral health, which support a healthy pregnancy and positive outcomes.
