Correct Answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

Correct Answer: A

Rationale: The correct action when inserting an NG tube is to help the client take sips of water. This helps facilitate the insertion of the tube by promoting swallowing and passage through the esophagus. Asking the client to swallow assists in guiding the tube into the stomach. Inserting the tube without asking the client to swallow may lead to incorrect placement or discomfort. Advancing the tube continuously without pausing can cause the tube to coil in the esophagus, leading to complications. Using a large-bore tube for insertion is unnecessary and may increase the risk of injury or discomfort for the client.

Correct Answer: A

Rationale: Placing a pillow under the patient's lower legs when in the prone position is essential to allow dorsiflexion of the ankles and some knee flexion, which promote relaxation. This position also helps in maintaining proper alignment of the spine. Options B, C, and D are incorrect because turning the head, positioning legs flat against the bed, and raising the head of the bed to 45 degrees are not appropriate actions for a patient in the prone position. Turning the head to one side with a large, soft pillow is commonly done for patients in the supine position to maintain proper alignment and airway patency. Positioning legs flat against the bed is more suitable for a patient in a supine or semi-fowler's position. Raising the head of the bed to 45 degrees is typically done for patients who need semi-fowler's positioning for respiratory support or to prevent aspiration.

Correct Answer: A

Rationale: The correct answer is A. Changing the colostomy bag every day is not necessary; it should be changed as needed, usually every 3-7 days. This statement indicates a need for additional teaching as frequent changes can irritate the skin and are not typically required. Choices B, C, and D are all correct statements regarding colostomy care. Avoiding gas-producing foods, emptying the bag when it is one-third to one-half full, and taking care of the skin around the stoma are all essential aspects of colostomy care to prevent complications and maintain skin integrity.

Correct Answer: A

Rationale: Practice sessions are an effective psychomotor approach to learning for adolescents with ostomies as they involve hands-on practice of ostomy care skills, which can help reinforce learning through active engagement. Demonstrations (choice B) can be helpful in providing visual guidance but may not offer the same level of active participation and practice as practice sessions. Written instructions (choice C) may be useful for reference but may not be as effective in developing psychomotor skills. Group discussions (choice D) focus more on verbal exchange and may not directly address the need for hands-on skill development required in managing ostomies. Therefore, practice sessions are the most suitable method for enhancing psychomotor learning in this scenario.
