Correct Answer: C

Rationale: The correct answer is C: 1” to 1.5”. When irrigating a colostomy, the client should insert the lubricated catheter about 1” to 1.5” into the stoma. This depth allows for effective irrigation of the colon without causing discomfort or damage. Inserting the catheter too shallow (choice A) may not reach the colon, while inserting it too deep (choices B and D) can cause injury or perforation. Therefore, the optimal depth of 1” to 1.5” ensures proper irrigation while minimizing risks of complications.

Correct Answer: B

Rationale: The correct answer is B because monitoring the site and progress of the infusion every hour is crucial to prevent complications like infiltration or infection in clients with hypertension. Choice A is incorrect as checking BP every hour is excessive. Choice C is incorrect as daily monitoring may not detect issues promptly. Choice D is incorrect as pulse rate monitoring is not directly related to IV fluid administration in this context. Monitoring the site and progress hourly ensures timely intervention if any issues arise.

Correct Answer: B

Rationale: The correct answer is B because focusing on the patient's presenting situation is the first step in the problem-oriented approach. This allows the nurse to gather relevant data related to the current health issue, which is crucial for identifying the problem and formulating a care plan. Option A is incorrect as chronological order may not prioritize the most critical data. Option C is incorrect as interpretations come after data collection. Option D is incorrect as observation typically follows data collection and analysis. Focusing on the patient's presenting situation ensures efficient and effective data collection for problem-solving.

Correct Answer: C

Rationale: The correct answer is C: Trunk. The thoracic cord supplies nerves to the trunk region of the body. The thoracic spinal nerves innervate the chest, abdomen, and back. They control sensation and movement in these areas. The head (A) is mainly supplied by cranial nerves, the pelvis (B) is innervated by lumbar and sacral nerves, and the coccyx (D) is supplied by the sacral nerves. Therefore, the correct answer is C as it aligns with the anatomical distribution of the thoracic spinal nerves.

Correct Answer: B

Rationale: The correct answer is B because a fixed nodular mass with dimpling of the overlying skin is highly indicative of breast cancer. This finding suggests an invasive tumor pulling on the skin, causing dimpling. Other choices are incorrect because slight breast asymmetry (A) is common, bloody nipple discharge (C) can be benign or due to other conditions, and multiple freely movable masses (D) are more indicative of benign breast conditions like fibrocystic changes.
