A patient presents with acute onset of severe headache, visual disturbances, and vomiting. Imaging reveals a tumor compressing the optic chiasm. Which of the following neurological conditions is most likely responsible for these symptoms?

Correct Answer: C

Rationale: A pituitary adenoma is a type of benign tumor that arises from the pituitary gland, which is located at the base of the brain. When a pituitary adenoma grows large enough, it can compress surrounding structures, including the optic chiasm – the point at which the optic nerves cross over in the brain. Compression of the optic chiasm can lead to symptoms such as vision problems (e.g., visual disturbances), headaches, and nausea/vomiting, which are consistent with the presentation described in the question. Meningiomas, glioblastoma multiforme, and medulloblastomas are less likely to compress the optic chiasm and present with different characteristic symptoms based on their locations and growth patterns.

Correct Answer: C

Rationale: The nurse's best approach to address the patient's confusion about their medication regimen is to use a teach-back method to assess understanding and clarify any misconceptions. This method involves the nurse asking the patient to explain in their own words how they will take their medications, what each medication is for, and any potential side effects they should watch for. By using the teach-back method, the nurse can confirm the patient's comprehension and correct any misunderstandings in a supportive and non-judgmental manner. This approach promotes patient education, empowerment, and adherence to the medication regimen. Providing written instructions alone (Choice A) may not be sufficient if the patient has difficulty reading or understanding written information. Explaining the medication regimen using complex medical terminology (Choice B) can further confuse the patient, making it harder for them to grasp the information. Dismissing the patient's concerns and reassuring them that the medication is safe (Choice D) does not address the root of the issue and

Correct Answer: B

Rationale: The nurse's best approach to address the patient's fear of pain is to provide accurate information about pain management strategies and options. In doing so, the nurse can help alleviate the patient's concerns by empowering them with knowledge and potential solutions for managing pain during and after the procedure. By acknowledging the patient's fear and addressing it with practical information, the nurse can build trust, reduce anxiety, and create a more supportive and collaborative environment for the patient. Dismissing, ignoring, or invalidating the patient's fear would not be effective in addressing the underlying concerns and could potentially lead to increased distress and resistance to the recommended procedure.

Correct Answer: B

Rationale: The nurse's best approach to address non-compliance with prescribed medications and treatment plans is to actively listen to the patient's reasons for non-compliance. By acknowledging and addressing any barriers or concerns the patient may have, the nurse can work collaboratively with the patient to find effective solutions. This approach promotes open communication, trust, and a patient-centered care plan that takes into consideration the patient's individual needs and circumstances. Dismissing the patient's reasons (choice A), ignoring the non-compliance (choice C), or resorting to a confrontational approach (choice D) are less effective strategies that may lead to further resistance and hinder the patient's willingness to engage in their treatment.

Correct Answer: D

Rationale: Addison's disease is a rare endocrine disorder characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production. The symptoms of Addison's disease include fatigue, weakness, hyperpigmentation of the skin (due to elevated levels of ACTH stimulating melanocytes), and salt craving (due to aldosterone deficiency). Low serum sodium levels and elevated serum potassium levels are also common laboratory findings in Addison's disease, as aldosterone plays a key role in maintaining electrolyte balance. Patients with Addison's disease are at risk of developing an adrenal crisis, which can be life-threatening if not promptly recognized and treated with glucocorticoid and mineralocorticoid replacement therapy.
