Correct Answer: A

Rationale: Correct answer: Skin care around the stoma site. Proper skin care around the stoma site is crucial for preventing skin irritation and infection, which are common issues for patients with new colostomies. While the schedule for colostomy bag replacement (Option B) is important, it is not the priority during initial discharge instructions. Techniques for odor control (Option C) are relevant but secondary to skin care for a new colostomy. Dietary modifications (Option D) may be discussed later but are not the priority at this stage.

Correct Answer: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing in COPD patients. While administering bronchodilator therapy as prescribed (Choice A) is important, it is not the priority in this scenario. Encouraging deep breathing and coughing exercises (Choice B) can be beneficial but do not take precedence over positioning for improved respiratory function. Increasing the oxygen flow rate (Choice D) can be considered after the initial positioning to relieve respiratory distress, making it a later intervention.

Correct Answer: A

Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.

Correct Answer: D

Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.
