Nokea
What medication is administered to treat uterine atony?
- A. ampicillin
- B. nitroglycerine
- C. magnesium sulfate
- D. methylergonovine
Correct Answer: D
Rationale: The correct answer is D: methylergonovine. Methylergonovine is a uterotonic medication used to treat uterine atony by causing the uterus to contract and prevent postpartum hemorrhage. Ampicillin (A) is an antibiotic, nitroglycerine (B) is a vasodilator, and magnesium sulfate (C) is a medication used for conditions like preeclampsia and eclampsia, but not specifically for uterine atony. Therefore, D is the correct choice for treating uterine atony.

A woman comes to the prenatal clinic because she thinks she is pregnant. Which of the following are probable signs of pregnancy? Select all that apply.
- A. Amenorrhea
- B. Uterine enlargement
- C. Positive pregnancy test
- D. Breast tenderness
Correct Answer: C
Rationale: The correct answer is C, positive pregnancy test. This is a probable sign of pregnancy because it directly indicates the presence of the pregnancy hormone hCG in the woman's body. Amenorrhea (choice A) and uterine enlargement (choice B) are actually presumptive signs of pregnancy, as they can be caused by factors other than pregnancy. Breast tenderness (choice D) is a possible sign of pregnancy but is not as specific or conclusive as a positive pregnancy test.
What is a possible complication of uterine tachysystole?
- A. Category I fetal heart rate tracing
- B. placenta previa
- C. fetal hypoxia
- D. prolapsed cord
Correct Answer: C
Rationale: Uterine tachysystole is excessive uterine contractions, reducing placental perfusion and causing fetal hypoxia. This can lead to potential complications such as fetal distress and hypoxia. Category I fetal heart rate tracing is typically associated with normal fetal heart rate. Placenta previa is unrelated to uterine tachysystole. Prolapsed cord is a potential complication of uterine hyperstimulation, not tachysystole.
What intervention may be used to manage failure to descend during labor?
- A. administering pain medication
- B. allowing the patient to rest
- C. continuing to push for an extended period of time
- D. using forceps or a vacuum to assist delivery
Correct Answer: D
Rationale: The correct answer is D because using forceps or a vacuum to assist delivery can help manage failure to descend during labor by aiding in the descent of the baby through the birth canal. Forceps or vacuum extraction can provide the necessary assistance to safely deliver the baby when maternal pushing alone is insufficient.
Explanation for why the other choices are incorrect:
A: Administering pain medication does not address the underlying issue of failure to descend during labor.
B: Allowing the patient to rest may not resolve the issue of failure to descend and could potentially delay necessary interventions.
C: Continuing to push for an extended period of time without progress can lead to maternal exhaustion and fetal distress without addressing the root cause of failure to descend.
When the deceleration pattern of the fetal heart rate mirrors the uterine contraction, which nursing action is indicated?
- A. Reposition the patient.
- B. Apply a fetal scalp electrode.
- C. Record this normal pattern.
- D. Administer oxygen by nasal cannula.
Correct Answer: C
Rationale: Rationale for correct answer (C): Recording the normal pattern is indicated because the deceleration pattern mirroring uterine contractions is a reassuring sign of fetal well-being. It indicates a physiologic response to labor. Repositioning the patient (A) is unnecessary as the pattern is normal. Applying a fetal scalp electrode (B) is invasive and unnecessary in this scenario. Administering oxygen (D) is not indicated as the fetal heart rate pattern is normal.
The nurse will monitor for aspiration, thought processes, and improved mobility after which complication?
- A. neurologic dysfunction
- B. Measure blood loss.
- C. gestational diabetes
- D. postpartum hemorrhage
Correct Answer: D
Rationale: The correct answer is D: postpartum hemorrhage. The nurse monitors for aspiration due to potential bleeding or clotting issues postpartum. Monitoring thought processes is important as postpartum hemorrhage can lead to hypovolemic shock affecting cognition. Improved mobility is assessed as excessive bleeding can cause weakness. Neurologic dysfunction (choice A) is not directly related to postpartum hemorrhage. Measuring blood loss (choice B) is important but not the primary focus after postpartum hemorrhage. Gestational diabetes (choice C) is a separate condition unrelated to postpartum hemorrhage.
