Explanation

The left lateral position is the recommended standard of care to prevent supine hypotensive syndrome in late pregnancy.
In this position, the gravid (pregnant) uterus is displaced to the left, moving its weight off the inferior vena cava and the abdominal aorta.
This maneuver relieves vessel compression, which promotes optimal venous return to the heart and increases maternal cardiac output.
Enhanced cardiac output ensures adequate perfusion and oxygenation for both the mother and the fetus, which is especially critical in a high-risk condition like PIH.

Option A: The inferior vena cava (IVC) lies on the right side of the vertebral column. Positioning the client on her right side does not effectively relieve the compression of the IVC by the heavy uterus.
Option B: Lying flat on the back (supine) is the primary cause of aortocaval compression. A small pillow under the head provides no benefit in displacing the uterus to relieve this pressure.
Option D: While Semi-Fowler's position elevates the head of the bed, the patient's torso is still in a supine orientation. The weight of the uterus continues to compress the great vessels against the spine.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Maternal positioning in late pregnancy to prevent supine hypotensive syndrome in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Correct positioning is a critical, non-pharmacological nursing intervention to ensure maternal and fetal safety before procedures like C-section, especially in high-risk conditions like PIH.
Nurses must continuously monitor for signs of supine hypotension, such as dizziness, pallor, nausea, and a drop in blood pressure, and be prepared to immediately reposition the patient.
This principle is also vital during labor, transport, and any instance where a woman in late pregnancy must lie down.

How to Approach the Question

Identify the patient's key characteristics: a client in late-stage pregnancy (admitted for C-section) with a comorbidity (PIH).
Understand the primary physiological risk associated with positioning in late pregnancy: the weight of the gravid uterus.
Recall the anatomical location of the inferior vena cava and aorta in relation to the spine and uterus.
Connect the patient's position to the risk of aortocaval compression, which leads to supine hypotensive syndrome.
Evaluate each option based on its ability to prevent this compression. The left lateral position is the only option that effectively displaces the uterus to the left, away from the major vessels.
Conclude that the left-sided position is the safest choice to optimize maternal and fetal circulation.

Concept Tested & Keywords

Concept Tested: Maternal positioning in late pregnancy to prevent supine hypotensive syndrome.
Stem keywords: pregnancy induced hypertension, C-section, before the surgery, position
Lead-in keywords: should keep the client in
Clinical cues: The patient is pregnant and admitted for a C-section, indicating she is in the later stages of pregnancy where the uterus is large and heavy.
Clinical cues: The diagnosis of Pregnancy-Induced Hypertension (PIH) signifies a high-risk pregnancy where optimal placental perfusion is critical.
