Correct Answer is D

Explanation

A. Facial flushing is not typically associated with end-stage kidney disease and waiting for transport to dialysis. It may be indicative of other conditions such as fever, allergic reactions, or hormonal changes.
B. Hypotension is not a common finding in patients with end-stage kidney disease.

These patients often experience hypertension due to fluid overload and electrolyte imbalances.
C. Diaphoresis, or excessive sweating, is not typically associated with end-stage kidney disease and waiting for transport to dialysis. It may occur in response to other factors such as fever, pain, or anxiety.

D. Peripheral edema, or swelling in the extremities, is a common finding in patients with end-stage kidney disease due to fluid retention and impaired fluid balance regulation.

A. "The pain occurs as a residual pain from cholecystitis." B. "The pain results from lying in one position too long during surgery." C. "The pain is caused from the nitrous dioxide injected into the abdomen." D. "The pain will dissipate if you ambulate frequently."

Correct Answer is D

Explanation

A. Postoperative pain typically resolves after a laparoscopic cholecystectomy since the surgery removes the gallbladder
B. While positioning during surgery can cause discomfort, isolated right shoulder pain is more commonly attributed to the diaphragmatic irritation from residual nitrous oxide in the abdomen.

C. Nitrous dioxide used during laparoscopic procedures is not associated with referred pain to the right shoulder. The pain is due to carbon dioxide gas used during the procedure resulting in the irritation of the diaphragm.
D. This pain is often due to the carbon dioxide used to inflate the abdomen during surgery, which can irritate the diaphragm and refer pain to the shoulder. Ambulation helps to absorb the gas more quickly.
