ATI Pathophysiology Exam 1

Correct Answer: B

Rationale: When a patient is receiving amphotericin B, which is known to cause renal toxicity, they are most likely to require magnesium supplementation. Amphotericin B can lead to renal loss of magnesium, potassium, and calcium. Magnesium is an essential mineral that plays a vital role in various physiological functions, and its levels need to be monitored and supplemented when necessary. Chloride, glucose, and sodium are not typically supplemented in the context of amphotericin B therapy for a serious fungal infection.

Correct Answer: A

Rationale: Magnesium is the correct answer as it is found in higher concentrations within intracellular fluid, where it plays vital roles in various cellular functions. Sodium, chloride, and bicarbonate are predominantly found in extracellular fluid rather than intracellular fluid, making them incorrect choices for this question.

Correct Answer: D

Rationale: The correct answer is D: Metabolic acidosis. Severe diarrhea can lead to metabolic acidosis because the loss of bicarbonate ions in the stool results in an overall decrease in the body's bicarbonate levels. Respiratory acidosis (choice A) is caused by retention of carbon dioxide, usually due to inadequate alveolar ventilation. Metabolic alkalosis (choice B) is characterized by elevated pH and bicarbonate levels, usually caused by conditions like vomiting. Respiratory alkalosis (choice C) is a condition of low blood carbon dioxide levels and high pH, often due to hyperventilation.

Correct Answer: B

Rationale: The correct answers are A, C, and D. Redness, swelling, and warmth are classic signs of acute inflammation. Redness occurs due to increased blood flow, swelling is caused by leakage of fluid into tissues, and warmth is due to the vasodilation and increased blood flow in the affected area. Fatigue is not a cardinal sign of acute inflammation and is not directly associated with the inflammatory response.

Correct Answer: B

Rationale: The correct answer is B: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events such as heart attacks and strokes, especially in older patients. Monitoring for signs and symptoms of cardiovascular issues is crucial when administering testosterone therapy. Choices A, C, and D are incorrect because testosterone therapy does not typically lead to an increased risk of breast cancer, liver dysfunction, or prostate cancer.
