The nurse knows that proper placement of the tocotransducer for electronic fetal monitoring is placed
Over the uterine fundus
On the fetal scalp
Inside uterus
Over the mother's lower abdomen
The Correct Answer is A
A. Over the uterine fundus: The tocotransducer measures uterine contractions by detecting changes in abdominal wall tension, which are most prominent at the uterine fundus. Placement over the fundus allows optimal detection of contraction frequency and duration, even though intensity is not directly measured. Proper placement is essential for accurate external monitoring of uterine activity.
B. On the fetal scalp: This placement is associated with internal fetal heart rate monitoring using a fetal scalp electrode, not with the tocotransducer. The tocotransducer is an external device and does not attach to the fetus or assess fetal heart rate directly.
C. Inside uterus: Internal monitoring of uterine contractions requires an intrauterine pressure catheter (IUPC), not a tocotransducer. The tocotransducer is noninvasive and placed externally on the maternal abdomen rather than inside the uterine cavity.
D. Over the mother’s lower abdomen: The lower abdomen does not provide reliable assessment of uterine contractions because contractions originate at the fundus and move downward. Placement here may result in inaccurate or weak contraction tracings.

Correct Answer is D
Explanation
A. Initiate an intravenous line: Establishing IV access is important for administering medications or fluids, but immediate oxygenation takes priority to prevent hypoxia and tissue damage in a suspected pulmonary embolism.
B. Assess the client's blood pressure: Monitoring vital signs, including blood pressure, is essential for detecting hemodynamic instability, but it is secondary to ensuring adequate oxygenation in the acute phase of a pulmonary embolism.
C. Prepare to administer Morphine sulfate: Morphine may relieve pain and anxiety, but it does not address the primary threat of hypoxemia or impaired oxygen delivery, making it a lower priority intervention.
D. Administer oxygen at 8 to 10L/min by face mask: Supplemental oxygen helps maintain adequate oxygen saturation, reduces hypoxemia, and supports vital organ perfusion. In a client with sudden dyspnea and tachycardia suggestive of a pulmonary embolism, rapid oxygen delivery is the immediate priority.
Correct Answer is C
Explanation
A. Flex her knee while resting: Flexing the knee repeatedly can increase venous stasis and may worsen symptoms if a deep vein thrombosis (DVT) is present. It is not recommended in suspected thromboembolic events.
B. Massage the area: Massaging a calf with pain and redness in the postpartum period can dislodge a thrombus and cause a potentially life-threatening pulmonary embolism. This intervention is contraindicated.
C. Elevate her leg: Elevating the affected leg promotes venous return, reduces swelling, and can help alleviate discomfort. It is a safe supportive measure while awaiting evaluation by a healthcare provider.
D. Apply cold compress: Cold compresses are generally used for acute inflammation or trauma. In suspected DVT, cold application does not address the underlying venous obstruction and is not a priority intervention.
