Which patient statement indicates to the nurse that further instruction is needed about chronic syndrome of inappropriate antidiuretic hormone (SIADH)?

• "I should weigh myself daily and report sudden weight loss or

gain."

• "I need to shop for foods low in sodium and avoid adding salt

to food."

• "I need to limit my fluid intake to no more than 1 quart of

liquids a day."

• "I should eat foods high in potassium because diuretics cause

potassium loss."

ANS: B

Rationale; Patients with SIADH are at risk for hyponatremia, and a sodium supplement may be prescribed. 1 / 4

The other patient statements are correct and indicate successful teaching has occurred.

A patient who is disoriented and reports a headache and muscle cramps is hospitalized with syndrome of inappropriate antidiuretic hormone (SIADH). Which initial laboratory result would the nurse expect?

• Elevated hematocrit
• Decreased serum sodium
• Increased serum chloride
• Low urine specific gravity

ANS: B

Rationale; When water is retained, the serum sodium level will drop below normal, causing the clinical manifestations reported by the patient. The hematocrit will decrease because of the dilution caused by water retention. Urine will be more concentrated with a higher specific gravity. The serum chloride level will usually decrease along with the sodium level.

Which problem would the nurse anticipate for a patient admitted to the hospital with diabetes insipidus?

• Generalized edema
• Respiratory distress
• Fluid volume overload
• Disturbed sleep pattern

ANS: D

Rationale; Nocturia occurs because of the polyuria caused by diabetes insipidus. Edema, excess fluid volume, and respiratory distress are not expected.

Which information will the nurse teach a patient who has been newly diagnosed with Graves' disease?

• Antithyroid medications may take months for full effect.
• Restriction of iodine intake will help reduce thyroid activity.
• Exercise is contraindicated to avoid increasing metabolic rate.
• Surgery will eventually be required to remove the thyroid

gland.

ANS: A

Rationale; Medications used to block the synthesis of thyroid hormones may take 2 months before the full effect is seen. 3 / 4

Large doses of iodine are used to inhibit the synthesis of thyroid hormones. Exercise using large muscle groups is encouraged to decrease the irritability and hyperactivity associated with high levels of thyroid hormones. Radioactive iodine is the most common treatment for Graves' disease, although surgery may be used.

A patient who had a subtotal thyroidectomy earlier today develops laryngeal stridor and a cramp in the right hand upon returning to the surgical nursing unit. Which collaborative action will the nurse anticipate next?

• Plan for emergency tracheostomy.
• Administer IV calcium gluconate.
• Prepare for endotracheal intubation.
• Begin thyroid hormone replacement.

ANS: B

Rationale; The patient's clinical manifestations of stridor and cramping are consistent with tetany caused by hypocalcemia resulting from damage to the parathyroid glands during surgery. Endotracheal intubation or tracheostomy may be needed if the calcium does not resolve the stridor. Thyroid hormone replacement may be needed
