When reviewing the chart the nurse notes the fetus of a laboring woman is in a transverse lie. The nurse should anticipate which part of the fetus delivering first? 1\. the shoulder 2\. the occiput 3\. the buttocks 4\. the sinciput

Short Answer

Expert verified
1. the shoulder

Step by step solution

01

Understanding the Transverse Lie

The transverse lie refers to the position where the fetus is lying horizontally in the uterus, across the maternal abdomen, rather than in a vertical position which is normal (either head down or breech). In this position, none of the major parts (head or buttocks) are positioned towards the birth canal ready for delivery.
02

Identifying possible presenting parts in transverse lie

Given the transverse position of the fetus, the parts that can potentially present first are either the shoulder (which is closest to the birth canal in this position) or, in some rare cases, other parts like the arm or side of the body.
03

Matching options with typical presentation

In the given transverse lie situation, the most common presenting part would be the shoulder or the arm, since the fetus is positioned sideways. This matches option 1, as shoulder presentation is characteristic of a fetus in transverse lie.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Fetal Positioning in Labor
Understanding fetal positioning is crucial in monitoring and managing labor. The fetus can be in various positions, which affect labor progress and delivery approach. The ideal position for birth is a "vertex presentation," where the fetus is head down and facing the mother's back, allowing for a smoother delivery process. These positions are influenced by several factors:
  • Maternal pelvis size and shape
  • Fetal size and position
  • The amount of amniotic fluid
In labor, the midwives and doctors pay attention to how the fetus is positioned to anticipate potential complications or interventions needed, like cesarean sections for improper positioning.
Nursing Chart Interpretation
In obstetric care, accurate chart interpretation is vital. Nurses use charts to track the fetal position and maternal health indicators. This includes checking fetal heart rates, contractions, and other crucial parameters that indicate labor's progress.

Nurses are trained to look for specific indicators on the chart that might suggest issues, like fetal distress or unusual positioning, such as a transverse lie. Correct interpretation ensures timely decision-making and intervention, promoting safer deliveries.
  • Monitoring fetal heart rate
  • Recording contraction frequency and intensity
  • Observing the labor progression on a partogram
The information gathered is crucial for making informed decisions during labor.
Transverse Lie in Childbirth
A transverse lie is when the fetus is positioned sideways in the uterus. Unlike the typical vertical position where the head or buttocks are aimed toward the birth canal, the transverse lie presents several challenges.

In a transverse lie, delivery cannot occur naturally without repositioning or medical intervention. This position can cause complications and is generally managed with:
  • Version procedures to reposition the fetus into a more favorable position
  • Cesarean section if repositioning is unsuccessful or unsafe
Recognizing a transverse lie early in labor care enables proactive management to ensure the safety of both the mother and fetus.
Obstetric Nursing Concepts
Understanding obstetric nursing concepts is fundamental in ensuring effective maternity care. This involves knowledge about labor management, potential complications, and interventions to promote optimal outcomes.

Key areas include:
  • Understanding fetal positions and presentations, such as breech or transverse lie
  • Interpreting maternal and fetal health signs during labor
  • Applying interventions if complications arise
Nurses play a crucial role in monitoring and supporting the labor process, ensuring both maternal and fetal well-being are prioritized. Their expertise helps in anticipating and managing situations such as prolonged labor and unexpected fetal presentations like the transverse lie.

The requirements of informed consent are all of the following except: 1\. the patient must be capable of making decisions. 2\. once informed consent is given, it cannot be revoked. 3\. the decision must be made voluntarily without coercion. 4\. the patient must understand the potential risks and benefits that result from their decision making.

A crisis occurs when an individual: 1\. perceives a stressor to be threatening. 2\. has no support system. 3\. is exposed to a precipitating stressor. 4\. experiences a stressor and perceives coping strategies to be ineffective.

A 62-year-old patient with diabetes mellitus is started on the thiazide diuretic hydrochlorothiazide (Hydrodiuril) for mild hypertension. The nurse educates the patient: 1\. to start administration of regular insulin. 2\. that thiazide diuretics are relatively risk free. 3\. hydrochlorothiazide will prevent diabetes complications. 4\. to follow his blood glucose values closely.

Mr. Pips, aged 52, underwent a right lobectomy one day ago and is having difficulty handling mucous secretions. The nurse caring for Mr. Pips performs tracheobronchial suctioning on a p.r.n. basis. A potential complication of suctioning is lobar collapse. This can be avoided by: 1\. using a large catheter the same diameter as the trachea. 2\. applying suction at high pressure to accomplish the procedure as quickly as possible. 3\. applying suction continuously for 30 seconds or more. 4\. using a catheter the size that does not occlude the lumen of the airway during application of suction.

You ask the family to recall all past concrete events that caused them worry, concern, or grief that were related to the alcoholic member of the family. You have a "family session" to discuss the personal growth and goals of each family member that has been affected by the alcoholic family member. You allow time for them to vent their feelings and respect the perspective of each family member. This is an example of which type of nursing intervention? 1\. interventions to help solve family problems 2\. interventions to establish a nurse-family relationship 3\. interventions to change family behaviors 4\. interventions to deal with destructive behaviors
