Correct Answer: B

Rationale: The correct answer is B: Monitor for fatigue, muscle weakness, restlessness, and flushed skin. The patient is at risk for dehydration due to the combination of high temperature, age, and thiazide diuretic use. Thiazide diuretics can lead to electrolyte imbalances, including hypokalemia, which can cause symptoms such as muscle weakness and fatigue. Monitoring for signs of dehydration and electrolyte imbalances is crucial in this scenario to prevent complications. A: Making sure he drinks 8 glasses of water a day is not the priority as he is already at risk for dehydration and electrolyte imbalances. C: Hyperchloremia is not a common concern in this scenario based on the given lab values. D: Neurologic changes may occur in severe cases of electrolyte imbalances but monitoring for physical symptoms such as fatigue and muscle weakness is more relevant at this stage.

Correct Answer: A

Rationale: The correct answer is A: Avoid alcohol and caffeine. Alcohol and caffeine are diuretics that can increase urine output, leading to fluid loss and potential hypovolemia. This step is crucial in preventing further dehydration. Summary of incorrect choices: B: Increasing milk and dairy products can contribute to fluid intake but does not address the prevention of hypovolemia. C: While dried peas and beans can provide nutrients, they do not specifically address fluid intake or prevention of hypovolemia. D: Avoiding table salt or sodium-containing foods may help in reducing fluid retention but does not directly address fluid intake to prevent hypovolemia.

Correct Answer: C

Rationale: The correct answer is C: Surgical removal. Surgical removal of the cancerous tumor is the best treatment before metastasis because it physically removes the cancer cells. Chemotherapy and radiation are used to treat cancer after it has spread, not as the primary treatment. Choice D is incorrect because not all types of cancer can be effectively treated with all three options.

Correct Answer: B

Rationale: The correct answer is B: Pneumonia Carnii. Pulmonary complications in AIDS patients are commonly caused by Pneumocystis jirovecii (previously known as Pneumocystis carinii) pneumonia. This opportunistic infection targets the lungs of immunocompromised individuals, leading to severe respiratory issues. Kaposi's Sarcoma (A) is a cancer commonly seen in AIDS patients but does not directly cause pulmonary complications. Filterable Virus (C) is a vague term and not a known cause of pulmonary issues in AIDS patients. Staphylococcus bacteria (D) can cause infections in AIDS patients but is less common than Pneumocystis jirovecii pneumonia in causing pulmonary complications.

Correct Answer: C

Rationale: The correct answer is C: ABG. Monitoring ABG in Guillain-Barre Syndrome patients is crucial as they are at risk for respiratory complications like respiratory failure due to muscle weakness. ABG provides information on oxygenation, ventilation, and acid-base balance. Regular monitoring helps detect early signs of respiratory distress and guide appropriate interventions. A: BUN and creatinine are important for assessing renal function, but they do not directly relate to acute complications in Guillain-Barre Syndrome. B: Hgb and Hct are markers for anemia, which is not a common acute complication in Guillain-Barre Syndrome. D: Serum potassium levels are important, but ABG monitoring takes precedence in patients with Guillain-Barre Syndrome due to the risk of respiratory issues.
