Correct Answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid consuming foods high in vitamin K. Foods rich in vitamin K, such as leafy greens, can interfere with the effectiveness of warfarin, an anticoagulant medication. Therefore, it is important for clients on warfarin therapy to maintain consistent vitamin K intake to keep their INR levels stable. The other options are also important but not the priority in the context of warfarin therapy. Ingesting foods high in vitamin K can affect the medication's efficacy, making it crucial to highlight this dietary consideration during client education.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, ensuring adequate oxygenation is the priority. Administering oxygen helps improve oxygen levels, which is crucial for the patient's well-being. Repositioning the patient, administering bronchodilators, or giving IV fluids are important interventions in certain situations, but when a patient is in respiratory distress, providing oxygen takes precedence over other actions.

Correct Answer: B

Rationale: Tracheal deviation is the correct finding to report to the provider. It can indicate a pneumothorax, which is a serious complication following a thoracentesis that requires immediate attention. Oxygen saturation of 96% is within the normal range and does not indicate an immediate issue. A pain level of 4 on a scale of 0 to 10 is subjective and may not be related to a serious complication. A temperature of 37.4°C (99.3°F) is slightly elevated but not a priority over tracheal deviation in this context.

Correct Answer: A

Rationale: The most important nursing intervention for a patient with a suspected pulmonary embolism is to administer anticoagulants. Anticoagulants help prevent further clot formation in the patient's blood vessels, reducing the risk of complications such as worsening of the pulmonary embolism or development of new clots. Administering oxygen (Choice B) may be necessary to support the patient's oxygenation, but anticoagulants take precedence as they target the underlying cause of the pulmonary embolism. Repositioning the patient (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of patient care but are not the primary intervention for a suspected pulmonary embolism.

Correct Answer: A

Rationale: The correct action when digitally evacuating stool from a client with a fecal impaction is to insert a lubricated gloved finger and advance along the rectal wall. This technique helps prevent trauma to the client. Choice B is incorrect because stimulating peristalsis is not the appropriate action for digitally evacuating stool. Choice C is incorrect as applying pressure to the abdomen can be uncomfortable and ineffective. Choice D is also incorrect because increasing fluid intake is not directly related to the digital evacuation procedure.
