Correct Answer: A

Rationale: The correct answer is A. Sucralfate is most effective when taken 1 hour before meals to protect the stomach lining. Option B is incorrect because sucralfate should not be taken after meals. Option C is incorrect because sucralfate is typically taken on a regular schedule, not just when symptoms occur. Option D is incorrect because sucralfate should not be taken with milk, as it can interfere with its effectiveness.

Correct Answer: A

Rationale: The correct answer is A. Administering antibiotics late must be reported as it can compromise the effectiveness of the treatment. This delay can lead to subtherapeutic levels of the antibiotic in the client's system, potentially reducing its efficacy in combating the infection. Choice B, a client vomiting shortly after taking medication, should be noted but does not necessarily require an incident report unless it is a frequent occurrence. It could indicate a possible adverse reaction or intolerance to the medication. Choice C, a client requesting a statin at a specific time, and choice D, a client asking for pain medication slightly earlier, do not involve medication errors or deviations that pose immediate risks to the client's health, so they do not require incident reports.

Correct Answer: A

Rationale: The correct intervention for a client with obsessive-compulsive disorder is to allow the client enough time to perform rituals. This helps manage anxiety and stress in individuals with OCD. Allowing time for rituals can provide a sense of control and reduce distress. Choice B, giving the client autonomy in scheduling activities, may not address the core symptoms of OCD related to rituals and compulsions. Choice C, discouraging the client from exploring irrational fears, goes against the principles of exposure therapy, which is a common treatment for OCD. Choice D, providing negative reinforcement for ritualistic behaviors, is not recommended as it can reinforce the behavior rather than help the client manage it.

Correct Answer: A

Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.

Correct Answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.
