A nurse is reinforcing teaching a client who is scheduled for a barium swallow to evaluate dysphagia. Which of the following statements Indicate to the nurse that the client understands the instructions?
"I will expect a warm feeling when the dye is injected."
"I will drink plenty of fluids after the test."
"I will maintain a clear liquid diet 24 hours before the test."
"I will expect my stool to be black after this procedure."
Correct Answer : B
A. "I will expect a warm feeling when the dye is injected."
This statement is incorrect. Barium swallow involves swallowing a contrast medium, not an injection. The warm feeling might be associated with injected substances but not with a barium swallow.
B. "I will drink plenty of fluids after the test."
This statement is correct. After a barium swallow, it's important to drink plenty of fluids to help clear the barium from the body and prevent constipation.
C. "I will maintain a clear liquid diet 24 hours before the test."
This statement is incorrect. A clear liquid diet might be recommended before certain medical procedures, but for a barium swallow, often patients are asked to avoid eating or drinking for a 8 hours before the test.
D. "I will expect my stool to be black after this procedure."
Barium can cause stools to appear white or light-colored for several days after the procedure. Black stools could indicate the presence of gastrointestinal bleeding or other issues unrelated to the barium swallow.

Correct Answer is B
Explanation
A. Blood glucose 150 mg/dL:
This blood glucose level is slightly elevated but not significantly concerning on its own. It may be related to stress or other factors. In the context of acute gastroenteritis, it might be secondary to dehydration, but it is not an immediate priority unless the client is diabetic.
B. Potassium 2.5 mEq/L:
This is the correct answer. Low potassium levels (hypokalemia) are a severe concern, especially in the context of acute gastroenteritis where there can be significant losses through vomiting and diarrhea. Hypokalemia can lead to cardiac arrhythmias and needs urgent correction.
C. Weight loss of 3% of total body weight:
While weight loss is an important parameter, a 3% weight loss is usually not an immediate concern. In cases of acute gastroenteritis, rapid weight loss might indicate severe dehydration, but this choice is not as urgent as addressing a severe electrolyte imbalance like hypokalemia.
D. Urine specific gravity 1.035:
This specific gravity indicates concentrated urine, which could be due to dehydration. While this finding is important and indicates the need for rehydration, it is not as urgent as correcting a critically low potassium level.
Correct Answer is C
Explanation
A. Check the client for a positive Chvostek's sign.
Chvostek's sign is a clinical sign of hypocalcemia (low calcium levels), not related to the client's potassium levels. The given potassium level is low, not calcium.
B. Discontinue the TPN infusion.
While the potassium level is low, discontinuing TPN without addressing the potassium deficiency can lead to further complications. TPN can be adjusted to include potassium supplementation.
C. Request a potassium replacement.
The client's low potassium level (3.0 mEq/L) requires potassium replacement. This can be done through the TPN solution or via a separate IV infusion. This choice is correct.
D. Administer glucagon IM.
Glucagon is not used to treat low potassium levels.
