After sustaining a serious brain injury, the patient has recovered enough to be transferred to a rehabilitation unit for continued care. Which statement by the patient indicates that they understand realistic goal setting?

Ordered Dose: The doctor has prescribed Diltiazem at a rate of 2.5 mg per hour. This means the patient needs to receive 2.5 milligrams of Diltiazem every hour.

Medication Concentration: The medication is supplied as 125 mg of Diltiazem in 125 mL of fluid. This translates to a concentration of 1 mg of Diltiazem per 1 mL of solution.

Since the medication concentration is 1 mg/mL, delivering 2.5 mg of Diltiazem per hour requires infusing 2.5 mL of the solution per hour.

Therefore, the nurse should set the IV pump to deliver 2.5 mL/hr of the Diltiazem solution.

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.
