Correct Answer is A

Explanation

A. Chest x-ray results: This is the correct choice. After central venous catheter insertion, a chest x-ray is crucial to confirm correct catheter placement and to rule out complications such as pneumothorax or catheter malposition.
B. Serum osmolality: While serum osmolality can provide information about fluid and electrolyte balance, it is not directly related to verifying catheter placement or the immediate post-insertion assessment.
C. Intake and output record: Although important for monitoring fluid balance, the intake and output record does not confirm the proper placement of the central venous catheter.
D. Serum glucose level: This is not relevant to verifying the catheter placement or ensuring proper functioning immediately after insertion.

A. "I will increase my fluid and fiber intake while I am taking iron tablets." B. "I will take the tablets with water an hour before eating." C. "I will immediately call my health care provider if my stools turn green." D. "I will take a stool softener if I occasionally feel constipated."

Correct Answer is C

Explanation

A. "I will increase my fluid and fiber intake while I am taking iron tablets.": This statement is correct as increasing fluid and fiber can help manage constipation, a common side effect of iron supplementation.
B. "I will take the tablets with water an hour before eating.": This is correct because taking iron supplements on an empty stomach can improve absorption, and water helps dissolve the tablets.
C. "I will immediately call my health care provider if my stools turn green.": This statement indicates a misunderstanding, as green stools are a common and harmless side effect of iron supplements. They are not typically a cause for concern unless accompanied by other symptoms.
D. "I will take a stool softener if I occasionally feel constipated.": This is a correct and appropriate approach, as stool softeners can help alleviate constipation caused by iron supplements.
