A client with a history of atrial fibrillation is prescribed dabigatran (Pradaxa). Which instruction should the nurse include in the client's teaching?

Correct Answer: C

Rationale: The correct answer is C: Take the medication at the same time each day. This instruction is crucial for maintaining consistent blood levels of dabigatran, maximizing its effectiveness in preventing blood clots. Taking it at the same time each day helps establish a routine and reduces the risk of missed doses. Choice A is incorrect because dabigatran should be taken without regard to meals. Choice B is incorrect as vitamin K does not interact with dabigatran. Choice D is incorrect because increasing high-potassium foods is not necessary for dabigatran therapy.

Correct Answer: A

Rationale: The correct answer is A: Use oxygen continuously, even while sleeping. In COPD, maintaining consistent oxygen levels is crucial to prevent hypoxia. Oxygen therapy should be used continuously, including during sleep, to ensure adequate oxygenation. Using oxygen only when short of breath (Choice B) may lead to hypoxia during periods of rest. Reporting difficulty breathing (Choice C) is important but not specific to oxygen therapy. Taking off oxygen while eating or drinking (Choice D) can result in decreased oxygen levels, which can be dangerous for someone with COPD.

Correct Answer: B

Rationale: The correct answer is B: Notify the healthcare provider immediately. A CVP of 15 mm Hg in a client with sepsis may indicate fluid overload or cardiac dysfunction, which require prompt medical intervention. Notifying the healthcare provider allows for timely assessment and appropriate management. Administering a fluid bolus (A) without further evaluation can exacerbate fluid overload. Administering a diuretic (C) without knowing the underlying cause can be harmful. Continuing to monitor the CVP (D) is important, but immediate action is required due to the high CVP level.

Correct Answer: C

Rationale: The correct answer is C: Methotrexate (Rheumatrex). Methotrexate is a disease-modifying antirheumatic drug commonly prescribed for managing rheumatoid arthritis. It helps reduce inflammation and pain by targeting the immune system's overactivity. Acetaminophen (A) is a mild pain reliever and does not treat the underlying inflammation in rheumatoid arthritis. Ibuprofen (B) is a nonsteroidal anti-inflammatory drug (NSAID) that can help with pain and inflammation but is not as effective in managing rheumatoid arthritis as methotrexate. Prednisone (D) is a corticosteroid that can provide quick relief from inflammation and pain, but it is typically used for short-term management due to its potential side effects.

Correct Answer: B

Rationale: The correct answer is B: The client would not be able to prove malpractice in court. In this scenario, although the nurse made an error in administering a higher dose of morphine, the client's condition improved, as evidenced by stable vital signs and pain relief. Therefore, there was no harm caused to the client due to the mistake. In malpractice cases, the client needs to prove that harm or injury resulted from the healthcare provider's actions. Since the client's condition improved, it would be difficult to establish malpractice in this situation. Choice A is incorrect because negligence requires harm or injury to occur, which is not the case here. Choice C is incorrect as the Good Samaritan Act typically applies to individuals providing emergency care in good faith at the scene of an emergency, not within a healthcare setting. Choice D is incorrect as the focus is on the nurse's error in administering the incorrect dose, not on the healthcare provider's responsibility in this context.
