The nurse is caring for a client with a nasogastric (NG) tube. Which action should the LPN/LVN take to maintain patency of the tube?

Correct Answer: A

Rationale: The correct action to maintain patency of a nasogastric (NG) tube is to flush the tube with water before and after medication administration. Flushing helps prevent clogging and ensures that the tube remains clear for proper functioning. Securing the tube to the client's gown (Choice B) is important for stability but does not directly address tube patency. Checking the placement of the tube by auscultation (Choice C) is crucial for verifying correct placement but does not specifically relate to maintaining tube patency. Irrigating the tube with normal saline every shift (Choice D) is not a routine practice for maintaining tube patency and can lead to electrolyte imbalances.

Correct Answer: A

Rationale: Administering oxygen via a nasal cannula is the priority action for a client experiencing chest pain due to coronary artery disease. Oxygen therapy helps improve oxygenation, reduce myocardial workload, and relieve chest pain by increasing oxygen delivery to the heart muscle. While measuring vital signs, obtaining a 12-lead ECG, and encouraging pursed-lip breathing are important interventions, administering oxygen takes precedence in this situation to address the potential hypoxemia associated with chest pain in a client with a history of coronary artery disease.

Correct Answer: B

Rationale: When documenting client care, it is crucial to use standardized abbreviations to ensure clear communication and prevent misunderstandings. BRP for bathroom privileges is a recognized and commonly used abbreviation in healthcare settings. Choice A, SS for sliding scale, is not a standard abbreviation and can lead to confusion as it could be mistaken for other meanings. Choice C, OJ for orange juice, is informal and may not be universally understood in a healthcare context. Choice D, SQ for subcutaneous, is a valid abbreviation but may not be as relevant in the context of documenting client care compared to BRP, which is more specific and widely accepted.

Correct Answer: C

Rationale: Choice C is the correct answer because it demonstrates that the client understands the importance of communicating with the nurse if the pain persists while using the PCA device. This is crucial as it ensures proper pain management and monitoring. Choices A and B are incorrect because delaying the use of the device until necessary or being cautious about pushing the button too much do not necessarily reflect understanding of using the PCA device effectively. Choice D is incorrect as having someone else, like an adult child, push the dose button goes against the principle of the client self-administering the medication through the PCA device.

Correct Answer: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.
