Correct Answer: B

Rationale: The correct sequence for administering a large volume enema is as follows: 1. Insert the enema tube into the rectum, 2. Administer the enema solution, 3. Clamp the tube, 4. Remove the tube, 5. Wrap the end with tissue. Therefore, the nurse should remove the enema tube from the client's rectum after administering the enema solution. Choices A, C, and D are incorrect because the enema tube should be removed from the rectum after the administration of the solution, not before or during the process.

Correct Answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.

Correct Answer: B

Rationale: The correct answer is B: One medium apple with skin. Foods high in fiber, like apples with skin, are recommended to relieve constipation due to their fiber content, which aids in bowel regularity. Macaroni and cheese, yogurt, and roast chicken with white rice do not provide as much fiber and are less effective in alleviating constipation. While yogurt can sometimes contain probiotics that support gut health, it is not as effective in treating constipation as high-fiber foods like apples.

Correct Answer: A

Rationale: The correct first action for the nurse to take in this situation is to check the IV tubing for obstruction. By doing this, the nurse can assess if there is any blockage or kink in the tubing that is impeding the flow of the IV solution. This step is crucial as it helps in identifying the reason for the inadequate infusion rate. Increasing the infusion rate (Choice B) without first checking for obstructions can lead to potential complications if there is a blockage. Administering a bolus of fluid (Choice C) may not be appropriate without addressing the cause of the decreased infusion rate. Similarly, replacing the IV catheter (Choice D) is not the initial priority unless obstruction is ruled out and other troubleshooting measures have been taken.

Correct Answer: C

Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.
