A patient presents with fatigue, weakness, hyperpigmentation of the skin, and salt craving. Laboratory tests reveal low serum sodium levels and elevated serum potassium levels. Which endocrine disorder is most likely responsible for these symptoms?

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.

Correct Answer: C

Rationale: Pericarditis is the inflammation of the pericardium, the sac surrounding the heart. Patients with pericarditis typically present with sharp chest pain that worsens with deep breathing, changes in body position, and coughing. The pain tends to improve when the patient leans forward. This characteristic symptom of pericarditis is known as "pleuritic" chest pain. In contrast, stable angina presents as predictable chest pain that occurs with exertion and is relieved by rest or medications. Unstable angina is characterized by chest pain that occurs at rest or with minimal exertion and is considered a medical emergency. Myocarditis involves inflammation of the heart muscle and may present with symptoms such as chest pain, but it does not typically have the characteristic of worsening with deep breathing or changes in body position.

Correct Answer: A

Rationale: The given patient's symptoms of chest pain that occurs during heavy lifting or physical exertion and is relieved by rest are consistent with stable angina. Stable angina is characterized by predictable chest pain that occurs with exertion and is typically relieved by rest or nitroglycerin. The transient ST-segment depression on ECG is also a common finding in patients with stable angina, which reflects myocardial ischemia during episodes of chest pain triggered by exertion. In contrast, unstable angina is characterized by chest pain at rest or with minimal exertion that is of increasing frequency, severity, or duration. Acute myocardial infarction is associated with persistent ST-segment elevation or new Q-waves on ECG, and Prinzmetal's angina is characterized by chest pain at rest due to coronary artery spasm rather than exertion.

Correct Answer: C

Rationale: When assessing and managing distress in a patient with advanced dementia who is no longer able to communicate verbally, the palliative nurse should consider exploring non-verbal cues and behaviors to identify the underlying causes of distress. Since the patient cannot communicate through words, it is essential to pay close attention to their non-verbal cues such as facial expressions, body language, and changes in behavior. Distress in dementia patients can be caused by a variety of factors including physical discomfort, unmet needs, environmental stressors, emotional distress, or even medication side effects. By carefully observing and interpreting non-verbal cues, the nurse can gain insight into what might be causing the patient's distress and tailor interventions accordingly. Simply focusing on physical comfort measures may not address the root cause of the distress, and administering sedative medications without understanding the underlying cause is not considered best practice in palliative care for dementia patients.

Correct Answer: C

Rationale: The most appropriate intervention for the palliative nurse to prioritize in this situation is to offer emotional support and validate the patient's feelings about body image changes. End-stage renal disease can lead to significant physical changes such as edema and weight gain, which can impact a patient's body image and self-esteem. By providing emotional support and validating the patient's feelings, the nurse can help address the patient's distress and concerns, improving their overall psychological well-being. While providing education on dietary modifications (choice B) and prescribing diuretic medications (choice D) may be important aspects of managing fluid retention and edema, addressing the patient's emotional distress and body image concerns should be the initial priority in a palliative care setting. Encouraging the patient to accept their body changes (choice A) may overlook the emotional impact these changes have on the patient, making choice C the most appropriate intervention.
