The nurse administering potassium iodine for the treatment of goiter will:

mix the solution with an antacid to reduce gastric irritation.

pour the solution over ice to make it more palatable.

give the solution on an empty stomach.

give the well-diluted solution through a straw.

Answer and Explanation

The Correct Answer is D

A. Mix the solution with an antacid to reduce gastric irritation: Antacids are not recommended for diluting potassium iodide and may interact; standard advice is dilution with water or juice.
B. Pour the solution over ice to make it more palatable: Cooling isn’t the recommended safety measure; primary concern is avoiding staining teeth and minimizing irritation.
C. Give the solution on an empty stomach: Potassium iodide is often given with food or a full glass to reduce GI upset.
D. Give the well-diluted solution through a straw: Diluting and administering potassium iodide through a straw reduces the risk of staining teeth and limits mucosal irritation.

Correct Answer is D

Explanation

A. 0.45% sodium chloride (1/2 NS): 0.45% NS is hypotonic and not first-line for initial resuscitation of extracellular fluid losses from vomiting/diarrhea.
B. 0.225% sodium chloride (1/4 NS): This is more hypotonic and inappropriate for initial isotonic replacement.
C. 3% sodium chloride (3% NaCl): Hypertonic saline is used for severe hyponatremia/intracranial hypertension and is not appropriate for routine volume repletion from GI fluid losses.
D. LR (Lactated Ringers): For replacement of isotonic fluid losses (vomiting/diarrhea) an isotonic crystalloid such as Lactated Ringer’s (or 0.9% normal saline) is appropriate to restore intravascular volume and electrolytes.

A. Serum sodium 140 mEq/L B. Serum calcium 10.5 mg/dL C. Serum potassium 5.2 mEq/L D. Serum chloride 99 mEq/L

Correct Answer is C

Explanation

A. Serum sodium 140 mEq/L: Normal serum sodium (≈135–145 mEq/L); not an expected adverse effect of spironolactone.
B. Serum calcium 10.5 mg/dL: Mildly high calcium is not a characteristic adverse effect of spironolactone.
C. Serum potassium 5.2: Spironolactone is a potassium-sparing diuretic and commonly causes hyperkalemia (monitor K+ closely).
D. Serum chloride 99 mEq/L: Chloride ~99 mEq/L is within normal limits (≈98–106) and not specific to spironolactone toxicity.
