A nurse is assessing a client who has a fluid volume deficit. The nurse should expect which of the following findings?

Decreased hemoglobin (Hgb)

Increased blood urea nitrogen (BUN)

Increased urine ketones

Decreased urine specific gravity

Answer and Explanation

The Correct Answer is B

Choice A reason:
Decreased hemoglobin (Hgb) levels can be indicative of anemia or blood loss, but they are not typically associated with fluid volume deficit. In cases of fluid volume deficit, the Hgb concentration may actually appear elevated due to hemoconcentration as the plasma volume decreases.

Choice B reason:
Increased blood urea nitrogen (BUN) levels are expected in a fluid volume deficit because as the blood volume decreases, the concentration of solutes like urea can increase. This is often due to decreased renal perfusion and subsequent reduced renal function, leading to less urea being excreted through the kidneys.

Choice C reason:
Increased urine ketones are typically associated with diabetic ketoacidosis or starvation, not directly with fluid volume deficit. Ketones are produced when the body breaks down fats for energy, which is not a process directly related to fluid volume status.

Choice D reason:
Decreased urine specific gravity would not be expected in fluid volume deficit; in fact, one would expect the opposite. Specific gravity measures the kidney's ability to concentrate urine. In fluid volume deficit, the urine specific gravity would likely be increased as the body attempts to conserve water.

Correct Answer is D

Explanation

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.

A. "It is caused by the lack of production of insulin by the pancreas." B. "It is caused by the overproduction of growth hormone by the pituitary gland." C. "It is caused by the overproduction of parathormone by the parathyroid gland." D. "It is caused by the lack of production of aldosterone by the adrenal gland."

Correct Answer is D

Explanation

Choice A reason:
The lack of insulin production by the pancreas is related to diabetes mellitus, not Addison's disease. Insulin is a hormone that regulates blood sugar levels, and its deficiency leads to diabetes, not Addison's disease.

Choice B reason:
The overproduction of growth hormone by the pituitary gland leads to conditions such as acromegaly or gigantism, depending on the age at which the hormone levels become elevated. It is not related to Addison's disease, which involves the adrenal glands, not the pituitary gland.

Choice C reason:
The overproduction of parathormone by the parathyroid glands leads to hyperparathyroidism, which can cause a variety of symptoms including bone pain, kidney stones, and abdominal pain. This condition is not related to Addison's disease.

Choice D reason:
Addison's disease is indeed caused by the lack of production of hormones by the adrenal glands, particularly cortisol and aldosterone. Aldosterone helps to maintain blood pressure and the balance of sodium and potassium in the blood. When the adrenal glands do not produce enough aldosterone, it can lead to symptoms such as low blood pressure and salt cravings, which are characteristic of Addison's disease.
