One of the side effects of INH administration is peripheral neuropathy. To prevent this effect, Nurse Carlos teaches Andrew to:
- A. have a strict low cholesterol diet
- B. get extra bed rest 
- C. supplement the diet with pyridoxine
- D. avoid excessive sun exposure
Correct Answer: C
Rationale: Pyridoxine, also known as vitamin B6, is necessary for the prevention of INH-induced peripheral neuropathy. INH can lead to a deficiency of vitamin B6 in the body, which in turn can cause nerve damage and peripheral neuropathy. By supplementing the diet with pyridoxine, the risk of developing peripheral neuropathy as a side effect of INH administration can be minimized. It is an important preventive measure recommended for those undergoing treatment with INH to ensure the proper functioning of the nervous system and prevent nerve damage.
Which of the ff. safety instructions should the nurse give a patient who has temporarily dilated pupils?

A child has a postoperative appendectomy incision covered by a dressing. The nurse has just completed a prescribed dressing change for this child. Which description is an accurate documentation of this procedure?
- A. Dressing change to appendectomy incision completed, child tolerated procedure well, parent present
- B. No complications noted during dressing change to appendectomy incision
- C. Appendectomy incision non-reddened, sutures intact, no drainage noted on old dressing, new dressing applied, procedure tolerated well by child
- D. No changes to appendectomy incisional area, dressing changed, child complained of pain during procedure, new dressing clean, dry and intact
Correct Answer: C
Rationale: Option C provides a thorough and accurate documentation of the dressing change procedure for the postoperative appendectomy incision. This documentation includes essential details such as the condition of the incision site (non-reddened, sutures intact, no drainage noted on old dressing), the action taken (new dressing applied), and the outcome (procedure tolerated well by the child). It covers all the necessary aspects of the dressing change procedure and clearly indicates the status of the incision site before and after the intervention. Options A, B, and D do not provide as comprehensive and detailed information about the dressing change procedure and its outcomes, making option C the most appropriate choice for accurate documentation.
Jose is a 4-year-old child scheduled for a cardiac catheterization. What should be included in preoperative teaching?
- A. Directed at his parents because he is too young to understand
- B. Detailed in regard to the actual procedures so he will know what to expect
- C. Done several days before the procedure so that he will be prepared
- D. Adapted to his level of development so that he can understand
Correct Answer: D
Rationale: Preoperative teaching for Jose, a 4-year-old child, scheduled for a cardiac catheterization should be adapted to his level of development so that he can understand. Children at this age have limited cognitive and emotional understanding, so using simple language, visuals, and play-based strategies is essential. It is important to provide age-appropriate information to reduce anxiety and improve cooperation during the procedure. Preoperative teaching should focus on preparing Jose for what he will see, hear, and experience in a way that is tailored to his developmental stage. Involving play tools such as medical play dolls or child-friendly illustrations can help Jose grasp the concept of the procedure and alleviate fears. It is important to involve both Jose and his parents in the teaching process to ensure they understand how to support and prepare him for the procedure.
