A nurse is providing care with for a client diagnosed with human immunodeficiency virus. The client discusses concerns about transmitting the virus to their family members. What should the nurse include in client education? The nurse teaches the client to:

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.

A) Intestines:
While abdominal trauma can affect the intestines, Kehr's sign, Cullen's sign, and Gray Turner's sign are more commonly associated with damage to the spleen rather than the intestines. Kehr's sign, in particular, is a hallmark of splenic injury, with pain referred to the left shoulder due to diaphragmatic irritation from blood in the peritoneum.

B) Liver:
Liver injuries often present with right upper quadrant pain, jaundice, and elevated liver enzymes. While liver injuries can cause internal bleeding, Cullen's and Gray Turner's signs are more closely associated with retroperitoneal bleeding from the spleen rather than liver injuries. Kehr's sign, which is left-sided shoulder pain, would not typically indicate a liver injury.

C) Spleen:
The spleen is the most likely abdominal organ affected in this case due to the left-sided rib fractures. When the spleen is injured (often as a result of blunt trauma), it can cause intraperitoneal hemorrhage. This bleeding can irritate the diaphragm, leading to Kehr's sign, which presents as left shoulder pain. Additionally, Cullen's sign (periumbilical bruising) and Gray Turner's sign (flank bruising) are indicative of retroperitoneal bleeding, which can occur with splenic rupture or laceration.

D) Stomach:
While stomach injuries can occur with blunt abdominal trauma, they are less likely to cause the signs and symptoms seen in this patient (Kehr's, Cullen's, and Gray Turner's signs). Stomach trauma typically leads to pain and potential perforation, but it doesn't often cause the peritoneal bleeding patterns seen with splenic injuries.
