Correct Answer: B

Rationale: The highest priority for the PN is to assess the rate and depth of the client's respirations when a client is receiving morphine via a PCA pump. Respiratory depression is a life-threatening side effect of intravenous morphine administration. If the client's respiratory rate falls below 10 breaths/min, the PCA pump should be stopped, and the healthcare provider must be notified immediately to prevent further complications.

Correct Answer: A

Rationale: The correct answer is A: Dry mouth. Tiotropium, a commonly prescribed medication for COPD, can cause dry mouth as a side effect. While it may not be severe, clients should report it if it becomes bothersome. Blurred vision, nausea, and tachycardia are not typically associated with tiotropium use in the context of COPD.

Correct Answer: A

Rationale: The correct instruction for a client with GERD prescribed omeprazole is to take the medication in the morning before breakfast. Omeprazole works best when taken on an empty stomach, approximately 30 minutes before the first meal of the day. This timing maximizes its effectiveness in reducing stomach acid production and helps manage symptoms of GERD more efficiently.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of bleeding. Warfarin is an anticoagulant medication that works by prolonging the time it takes for blood to clot. Therefore, a potential adverse effect of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, nosebleeds, or blood in the urine or stool. Monitoring for these signs is essential to prevent serious complications associated with excessive bleeding.

Correct Answer: D

Rationale: The correct answer is to administer liraglutide once a day. Liraglutide is typically prescribed to be taken once daily, as directed by the healthcare provider. This dosing schedule helps maintain consistent levels of the medication in the body to effectively manage blood sugar levels in clients with diabetes mellitus type 2. It is important for the nurse to emphasize the importance of adherence to the prescribed dosing regimen to achieve optimal therapeutic outcomes.
