The correct answer is A. Pulmonary embolism.

This patient presents with a classic triad suggestive of pulmonary embolism (PE):

Acute dyspnea

Hypotension

Unilateral leg swelling (right leg)

In pregnancy, patients are at increased risk for deep vein thrombosis (DVT) due to:

Hypercoagulable state

Venous stasis

Vascular changes

A clot from the leg (DVT) can dislodge and travel to the lungs, causing a pulmonary embolism.

Why A is correct (Pulmonary embolism):

NREMT-aligned medical guidance emphasizes:

“Pulmonary embolism should be suspected in patients with sudden dyspnea and signs of DVT.”

“Unilateral leg swelling is a key indicator of possible deep vein thrombosis.”

Hypotension suggests a massive PE, which is life-threatening.

Why the other options are incorrect:

B. Congestive heart failure: Typically presents with bilateral edema and gradual onset dyspnea, not sudden symptoms with unilateral leg swelling.

C. Ruptured ectopic pregnancy: Causes abdominal pain and internal bleeding, not isolated dyspnea and leg swelling.

D. Preeclampsia: Characterized by hypertension, not hypotension, and usually includes edema and proteinuria but not acute dyspnea from embolism.

Exact Extracts:

“Pulmonary embolism presents with sudden shortness of breath and may include hypotension.”

“Unilateral leg swelling suggests deep vein thrombosis.”

“Pregnancy increases the risk of thromboembolic events.”

The correct answer is C. Myocardial infarction.

This question describes classic signs and symptoms of acute coronary syndrome (ACS), specifically a myocardial infarction (heart attack). Key findings include:

Chest pain

Shortness of breath (dyspnea)

Cool, pale, diaphoretic skin

Feeling of impending doom

These are hallmark features emphasized in EMT education for recognizing cardiac emergencies.

According to standard NREMT-aligned EMT educational content, patients experiencing myocardial infarction often present with:

“Chest discomfort or pain… may be described as pressure, squeezing, or heaviness”

“Dyspnea (shortness of breath)”

“Diaphoresis (cool, clammy skin)”

“A feeling of impending doom”

These findings occur due to decreased cardiac output and sympathetic nervous system activation, which leads to sweating, anxiety, and vasoconstriction (cool skin).

Why the other options are incorrect:

A. Aortic aneurysm: Typically presents with sudden tearing pain (often in the back), not the classic ACS presentation with diaphoresis and impending doom.

B. Chronic bronchitis: A long-term respiratory condition characterized by cough and mucus production, not acute chest pain with diaphoresis.

D. Congestive heart failure: Usually presents with fluid overload symptoms such as edema, crackles, and dyspnea, but not typically acute crushing chest pain with diaphoresis and impending doom.

Exact Extracts (NREMT-aligned EMT educational references):

“Chest pain or discomfort… pressure, squeezing, or heaviness”

“Shortness of breath (dyspnea)”

“Skin may be pale, cool, and diaphoretic”

“Patient may have a feeling of impending doom”

These combined findings strongly indicate acute myocardial infarction, making C the most appropriate answer.

The correct answer is D. Perform manual cervical stabilization.

Key Concept: Mechanism of Injury (MOI) and Priorities

This patient fell out of a tree, which is a significant mechanism of injury. Any fall from height raises concern for:

Spinal injury (especially cervical spine)

Multisystem trauma

Why D is correct:

According to NREMT trauma priorities:

Spinal motion restriction is initiated immediately when a significant MOI is present

The first action upon patient contact is to stabilize the cervical spine manually

NREMT-aligned guidance states:

“Manual cervical stabilization should be initiated immediately in patients with suspected spinal injury.”

“Falls from height are high-risk mechanisms requiring spinal precautions.”

Why the other options are incorrect:

A. Assess for distal circulationImportant, but comes after addressing life threats and spinal stabilization

B. Realign the extremityDone later if needed, after initial stabilization and assessment

C. Perform a rapid trauma assessmentOccurs after cervical spine stabilization is initiated

Exact Extracts (NREMT-aligned EMT educational references):

“Begin manual stabilization of the cervical spine immediately.”

“High-risk mechanisms include falls from height.”

“Address life threats first before focusing on isolated extremity injuries.”

Clinical Priority Summary:

Because this is a high-risk fall, the EMT must immediately protect the cervical spine, making D the correct answer.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Patients with an altered level of consciousness are at increased risk of airway compromise due to loss of protective reflexes. NREMT guidelines stress the importance of airway protection during transport.

The left lateral recumbent position (recovery position) is preferred because it allows secretions, vomitus, or blood to drain from the mouth, reducing the risk of aspiration. This position also helps maintain airway patency without requiring invasive airway devices.

Option A may be appropriate for respiratory distress but does not adequately protect the airway in patients with decreased consciousness.

Option C is unsafe because the patient cannot maintain posture or airway control.

Option D increases aspiration risk unless spinal precautions are required.

NREMT teaches that airway protection is the priority when transporting patients with altered mental status.
