A client with a closed head injury demonstrates signs of syndrome of inappropriate antidiuretic hormone (SIADH). Which additional finding should the nurse expect to obtain?

Weight gain of 2 pounds (0.91 kg) in one day.

Fremitus over the chest wall.

Serum sodium of 150 mEq/L (150 mmol/L).

Urine specific gravity of 1.004.

Answer and Explanation

The Correct Answer is A

Choice A reason: Weight gain of 2 pounds (0.91 kg) in one day is a sign of fluid retention, which occurs in SIADH due to excessive secretion of antidiuretic hormone (ADH). ADH causes the kidneys to reabsorb water and reduce urine output, leading to hyponatremia and hypervolemia.

Choice B reason: Fremitus over the chest wall is a sign of increased vibration or air movement in the lungs, which can indicate pneumonia, bronchitis, or pleural effusion. These are not related to SIADH, but may be complications of head injury or fluid overload.

Choice C reason: Serum sodium of 150 mEq/L (150 mmol/L) is a sign of hypernatremia, which is a high level of sodium in the blood. This is the opposite of what happens in SIADH, where sodium levels are low due to dilution by excess water.

Choice D reason: Urine specific gravity of 1.004 is a sign of diluted urine, which indicates low concentration of solutes in the urine. This is also the opposite of what happens in SIADH, where urine is concentrated and has a high specific gravity.

Correct Answer is D

Explanation

Choice A reason: Fasting blood sugar of 200 mg/dL (11.1 mmol/L) indicates hyperglycemia, which is a high level of glucose in the blood. It can be caused by diabetes mellitus, stress, infection, or medication. Hyperglycemia can cause symptoms such as thirst, hunger, frequent urination, fatigue, and blurred vision. However, it does not affect the safety or accuracy of MRI with contrast.

Choice B reason: Glycosylated hemoglobin A1c of 8% indicates poor glycemic control over the past three months. It can be caused by diabetes mellitus, chronic kidney disease, or hemoglobinopathy. Glycosylated hemoglobin A1c reflects the average blood glucose level over the lifespan of red blood cells, which is about 120 days. However, it does not affect the safety or accuracy of MRI with contrast.

Choice C reason: Blood urea nitrogen of 22 mg/dL (7.9 mmol/L) indicates mild azotemia, which is a high level of nitrogenous waste products in the blood. It can be caused by dehydration, high protein intake, gastrointestinal bleeding, or kidney impairment. Azotemia can cause symptoms such as nausea, vomiting, confusion, and lethargy. However, it does not affect the safety or accuracy of MRI with contrast.

Choice D reason: Serum creatinine of 1.9 mg/dL (169 umol/L) indicates moderate renal insufficiency, which is a reduced ability of the kidneys to filter and excrete waste products and fluids from the body. It can be caused by diabetes mellitus, hypertension, glomerulonephritis, or nephrotoxic drugs. Renal insufficiency can cause symptoms such as edema, anemia, electrolyte imbalance, and acidosis. It can also increase the risk of contrast-induced nephropathy, which is a sudden deterioration of kidney function after exposure to contrast media used for imaging studies such as MRI. Contrast-induced nephropathy can lead to acute kidney injury, dialysis requirement, or even death. Therefore, serum creatinine should be reported to the healthcare provider before MRI with contrast to assess the risk and benefit of the procedure and to take preventive measures such as hydration, medication adjustment, or alternative imaging modalities.

A. Canned vegetables with additional table salt. B. Pasta with herbal butter and no meat sauce. C. Citrus fruit and melon with a salt substitute. D. Whole milk and daily servings of ice cream.

Correct Answer is D

Explanation

Choice A reason: Canned vegetables with additional table salt are not a good choice for someone with cholecystitis, because they are high in sodium, which can increase fluid retention and inflammation. However, this choice is not eliminated by the client, so it does not indicate successful teaching.

Choice B reason: Pasta with herbal butter and no meat sauce is a good choice for someone with cholecystitis, because it is low in fat and protein, which can trigger gallbladder contractions and pain. This choice is not eliminated by the client, so it does not indicate successful teaching.

Choice C reason: Citrus fruit and melon with a salt substitute are also good choices for someone with cholecystitis, because they are high in vitamin C and water, which can help dissolve gallstones and prevent infection. This choice is not eliminated by the client, so it does not indicate successful teaching.

Choice D reason: Whole milk and daily servings of ice cream are bad choices for someone with cholecystitis, because they are high in fat and cholesterol, which can worsen gallbladder inflammation and increase the risk of gallstone formation. This choice is eliminated by the client, so it indicates successful teaching.
