A patient presents with recurrent episodes of deep vein thrombosis (DVT) and pulmonary embolism (PE). Laboratory tests reveal elevated levels of antiphospholipid antibodies (anticardiolipin and lupus anticoagulant). Which of the following conditions is most likely to cause these findings?

Correct Answer: D

Rationale: Antiphospholipid syndrome is characterized by abnormal antiphospholipid antibodies, which can lead to an increased risk of blood clots such as deep vein thrombosis (DVT) and pulmonary embolism (PE). The two most common antiphospholipid antibodies are anticardiolipin and lupus anticoagulant. Patients with antiphospholipid syndrome can present with recurrent thrombotic events, such as DVT and PE, due to the pro-thrombotic effects of these antibodies. Protein C deficiency, Protein S deficiency, and Antithrombin III deficiency are other causes of hypercoagulability but would not typically present with elevated antiphospholipid antibodies.

Correct Answer: B

Rationale: The symptoms described such as memory loss, impaired judgment, personality changes, difficulty with language, motor function, and coordination all point towards Alzheimer's disease. Alzheimer's is a progressive neurodegenerative disease that primarily affects memory and cognitive functions. Over time, it leads to severe impairment in daily activities and overall functioning. While Parkinson's disease, Huntington's disease, and ALS can also present with neurological symptoms, the combination of gradual-onset memory loss, cognitive decline, and functional impairments seen in this scenario is most characteristic of Alzheimer's disease.

Correct Answer: A

Rationale: The symptoms described - sudden-onset severe headache, nausea, vomiting, photophobia, neck stiffness, and positive Kernig and Brudzinski signs - are classic manifestations of meningitis. Meningitis is an inflammation of the meninges, the protective membranes covering the brain and spinal cord, often caused by infection. The sudden onset of these symptoms and signs, along with neck stiffness and positive Kernig and Brudzinski signs (indicative of meningeal irritation), strongly suggest meningitis as the most likely diagnosis in this scenario.

Correct Answer: B

Rationale: The most appropriate action for the nurse to take when noticing that the patient seems anxious and is avoiding eye contact is to ask the patient if they are feeling anxious and if they would like to talk about it. This approach shows empathy, concern, and openness to addressing the patient's emotional state. By directly acknowledging the patient's behavior and giving them the opportunity to express their feelings, the nurse can create a supportive and caring environment that promotes effective communication and trust between the patient and healthcare provider. It is important to consider the patient's emotional well-being alongside their physical health during consultations.

Correct Answer: B

Rationale: The nurse's best response when a patient asks about alternative treatment options is to provide the patient with information about those options, including their benefits and risks. It is important for the nurse to support the patient in their exploration of different treatment approaches and empower them to make informed decisions about their care. Dismissing the question, ignoring it, or discouraging alternative treatments are not appropriate responses and may hinder the patient's ability to make choices that align with their values and preferences. Therefore, providing information and facilitating an open discussion about alternative treatments is the most appropriate approach for the patient's best interest.
