A 45-year-old patient presents to the trauma unit after a gunshot wound (GSW) to the abdomen. The patient has a temperature of 92 degrees Fahrenheit, is restless and confused, and has large amount of blood noted from the nasogastric (NG) tube as well as from the indwelling urinary catheter. Which additional assessment finding likely causes death within the first 24 hours following this injury?
Heart rate of 130 beats per minute
PH of 7.21 (normal 7.35-7.45)
Serum potassium 5.7 mEq/L (normal 3,5-5.3)
Platelet count 200,000 (normal 150,000-450,000)
The Correct Answer is B
A) Heart rate of 130 beats per minute
A heart rate of 130 beats per minute is tachycardia, which is often a compensatory response to injury, particularly in cases of trauma, blood loss, or shock. It is common in the initial phase after trauma as the body attempts to compensate for decreased blood volume or oxygen delivery. However, tachycardia alone is not typically fatal in the immediate post-injury period and can often be managed.
B) pH of 7.21 (normal 7.35–7.45)
A pH of 7.21 indicates acidosis, which is life-threatening and typically arises from shock, blood loss, or severe trauma. Acidosis occurs when the body is unable to compensate for lactic acid or other metabolic byproducts that accumulate due to insufficient oxygen delivery to tissues. In the case of a gunshot wound to the abdomen, there is a high risk of internal bleeding, hypoperfusion, and hypoxia, all of which can lead to metabolic acidosis. Severe acidosis can cause organ failure, particularly affecting the heart, kidneys, and brain.
C) Serum potassium 5.7 mEq/L (normal 3.5–5.3)
A serum potassium of 5.7 mEq/L is elevated, but it is moderately high and not typically life-threatening unless it reaches much higher levels (e.g., >6.0 mEq/L), which can cause cardiac arrhythmias. Elevated potassium can occur due to cellular injury (e.g., muscle trauma or rhabdomyolysis), but it would need to be corrected to prevent complications like arrhythmias.
D) Platelet count 200,000 (normal 150,000–450,000)
A platelet count of 200,000 is within the normal range (150,000–450,000) and does not indicate a problem with coagulation. The blood loss and the NG tube hemorrhage mentioned in the scenario suggest that the patient may be at risk for bleeding, but a platelet count in the normal range suggests that the body’s ability to form clots is likely intact.

Correct Answer is A
Explanation
A) Assess the patient's neurological status and repeat vital signs:
In patients with a spinal cord injury (SCI) at T1, autonomic dysreflexia or neurogenic shock can lead to unstable vital signs, including hypotension and bradycardia. The most immediate concern in this scenario is to determine if the patient is experiencing neurogenic shock, which can result from the loss of sympathetic nervous system function below the level of the injury. By assessing the patient’s neurological status (such as checking for changes in motor function, sensation, or level of consciousness) and repeating vital signs, the nurse can gather the necessary data to make informed decisions about further interventions.
B) Ask the patient care tech to check on the patient:
While the patient care tech can assist with tasks, this is not the priority action. The nurse must immediately assess the patient's condition, particularly given the vital sign changes and the potential for a life-threatening situation like neurogenic shock. The nurse's clinical judgment and expertise are required to evaluate the situation appropriately.
C) Place the client in reverse Trendelenburg position:
Placing the patient in reverse Trendelenburg may help with hypotension in certain situations, but it is not the priority intervention for someone with a spinal cord injury at T1. In cases of neurogenic shock or autonomic dysreflexia, positioning alone will not correct the underlying issue.
D) Administer intravenous (IV) fluids to increase cardiac output:
While IV fluids may be necessary to treat hypotension in some situations, the nurse must first assess the patient’s neurological status and repeat vital signs to determine the cause of the hypotension and bradycardia. Administering IV fluids without understanding the underlying cause could be inappropriate or even harmful, particularly if the low blood pressure is related to neurogenic shock, which requires careful management.
Correct Answer is ["A","B","D"]
Explanation
A) Tachycardia: Tachycardia is commonly seen in left-sided heart failure as the heart attempts to compensate for the reduced cardiac output. To maintain adequate perfusion, the body increases the heart rate. The sympathetic nervous system is activated, causing an increase in heart rate to try to pump blood more efficiently despite the reduced pumping ability of the left ventricle.
B) Crackles: Crackles (also known as rales) are typically heard upon auscultation of the lungs in patients with left-sided heart failure. When the left ventricle fails to effectively pump blood, it causes blood to back up into the lungs, resulting in pulmonary congestion. This leads to fluid accumulation in the alveoli, causing crackling sounds during inhalation.
C) Ascites: Ascites is more commonly seen in right-sided heart failure or in cases of congestive heart failure where both sides of the heart are affected. Ascites is the accumulation of fluid in the abdomen, which is a consequence of right-sided heart failure causing blood to back up into the abdomen. In left-sided heart failure, ascites is generally not a primary symptom unless the failure becomes severe and involves both sides of the heart.
D) Dyspnea: Dyspnea, or shortness of breath, is a hallmark symptom of left-sided heart failure. The left ventricle's inability to pump blood efficiently leads to pulmonary congestion, which causes fluid to accumulate in the lungs. This fluid buildup reduces the lung's ability to exchange oxygen, resulting in difficulty breathing, especially on exertion or when lying down (orthopnea).
E) Peripheral edema: Peripheral edema is more characteristic of right-sided heart failure due to the backup of blood in the systemic circulation. While it can occur in cases of biventricular heart failure (both right and left sides of the heart are affected), it is not the primary finding in left-sided heart failure. Left-sided heart failure typically presents with pulmonary symptoms rather than systemic symptoms like peripheral edema.
