Syndrome Of Inappropriate Antidiuretic Hormone (Siadh) By Rnpedia

1. A male client is admitted for treatment of the syndrome of inappropriate antidiuretic hormone (SIADH). Which nursing intervention is appropriate?

Infusing I.V. fluids rapidly as ordered

Encouraging increased oral intake

Restricting fluids

Administering glucose-containing I.V. fluids as ordered

To reduce water retention in a client with the SIADH, the nurse should restrict fluids. Administering fluids by any route would further increase the client’s already heightened fluid load.

3. Nurse Alexandra is establishing a plan of care for a client newly admitted with SIADH. The priority diagnosis for this client would be which of the following?

Fluid volume deficit

Anxiety related to disease process

Fluid volume excess

Risk for injury

SIADH results in fluid retention and hyponatremia. Correction is aimed at restoring fluid and electrolyte balance. Anxiety and risk for injury should be addressed following fluid volume excess.

4. Which of these signs suggests that a male client with the syndrome of inappropriate antidiuretic hormone (SIADH) secretion is experiencing complications?

Tetanic contractions

Neck vein distention

Weight loss

Polyuria

SIADH secretion causes antidiuretic hormone overproduction, which leads to fluid retention. Severe SIADH can cause such complications as vascular fluid overload, signaled by neck vein distention. This syndrome isn’t associated with tetanic contractions. It may cause weight gain and fluid retention (secondary to oliguria).

6. A client is admitted to the unit with a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). For which electrolyte abnormality will you be sure to monitor?

Hypokalemia

Hyperkalemia

Hyponatremia

Hypernatremia

SIADH causes a relative sodium deficit due to excessive retention of water.

Explanation

SIADH causes a relative sodium deficit due to excessive retention of water.

7. A nurse assessing a client with SIADH would expect to find laboratory values of:

Serum Na= 150 mEq/L and low urine osmolality

Serum K= 5 mEq/L and low serum osmolality

Serum Na=120 mEq/L and low serum osmolality

Serum K= 3 mEq/L and high serum osmolality

In SIADH (syndrome of inappropriate antidiuretic hormone secretion), there is an excessive release of ADH, leading to water retention and dilutional hyponatremia. The low serum osmolality indicates that there is an excess of water in the body, causing the dilution of sodium levels. A serum sodium level of 120 mEq/L is considered low and is consistent with SIADH. Therefore, the correct answer is Serum Na=120 mEq/L and low serum osmolality.

8. Adequate fluid replacement and vasopressin replacement are objectives of therapy for which of the following disease processes?

Diabetes mellitus.

Diabetes insipidus.

Diabetic ketoacidosis.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Maintaining adequate fluid and replacing vasopressin are the main objectives in treating diabetes insipidus. An excess of antidiuretic hormone leads to SIADH, causing the patient to retain fluid. Diabetic ketoacidosis is a result of severe insulin insufficiency.
