A nurse is preparing a client for surgery. Which of the following is a priority when completing an assessment preoperatively?

Choice A reason: Hypertension
Hypertension, or high blood pressure, is not typically an expected finding in hypovolemic shock. In fact, one would expect the opposite, hypotension, due to the decreased circulating blood volume. Hypertension might be present in the initial stages due to compensatory mechanisms, but as the condition progresses, blood pressure usually drops.

Choice B reason: Bradypnea
Bradypnea, or abnormally slow breathing, is not a common finding in hypovolemic shock. Instead, tachypnea, or rapid breathing, may be observed as the body attempts to compensate for reduced oxygen delivery to tissues.

Choice C reason: Oliguria
Oliguria, or low urine output, is an expected finding in hypovolemic shock. As the blood volume decreases, the kidneys receive less blood flow, leading to reduced urine production. This is a protective mechanism to conserve body fluids, but it also indicates the severity of fluid loss and the need for urgent intervention.

Choice D reason: Flushing of the skin
Flushing of the skin is not an expected finding in hypovolemic shock. Instead, the skin may appear pale, cool, and clammy due to vasoconstriction and reduced blood flow to the periphery as the body prioritizes blood flow to vital organs.

Choice A reason:
Dyspepsia, commonly known as indigestion, is not typically associated with SIADH. It is a condition characterized by chronic or recurrent pain in the upper abdomen and is not linked to the overproduction of antidiuretic hormone.

Choice B reason:
Osteoarthritis is a degenerative joint disease and does not cause SIADH. It is characterized by the breakdown of joint cartilage and underlying bone, most commonly from middle age onward, causing pain and stiffness, especially in the hip, knee, and thumb joints.

Choice C reason:
Liver cirrhosis can lead to complications that may contribute to fluid imbalance, but it is not a direct cause of SIADH. SIADH is more commonly associated with conditions that affect the central nervous system or certain types of cancer.

Choice D reason:
Lung cancer, particularly small cell lung cancer, is a well-known cause of SIADH. Tumors in the lungs can produce and release antidiuretic hormone independently, leading to the syndrome of inappropriate antidiuretic hormone secretion.
