ATI Pathophysiology Exam 3

1. Which of the following imbalances is found in clients with syndrome of inappropriate antidiuretic hormone (SIADH)?

Correct answer: C

Rationale: The correct answer is C: Increased secretion of antidiuretic hormone (ADH). Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of ADH, which leads to water retention and dilution of blood sodium levels. Choices A, B, and D are incorrect because SIADH is not associated with decreased insulin production, decreased ADH production, or increased production of insulin.

2. What is the primary cause of angina?

Correct answer: B

Rationale: The correct answer is B: Obstruction of the coronary arteries. Angina is primarily caused by a reduced blood flow to the heart due to blockages or narrowing in the coronary arteries. Choice A is incorrect because while increased oxygen demand can contribute to angina symptoms, it is not the primary cause. Choice C is incorrect as angina is not caused by a lack of oxygen in the lungs. Choice D is also incorrect as angina is not related to decreased blood supply to the liver.

3. Hematopoiesis occurs primarily in the bone marrow. What cells are formed during this process?

Correct answer: B

Rationale: The correct answer is B: Red blood cells. Hematopoiesis is the process of blood cell formation that primarily occurs in the bone marrow. Red blood cells are one of the main cell types formed during this process. Pancreatic beta cells (Choice A), gastric parietal cells (Choice C), and neurons and glial cells (Choice D) are not formed during hematopoiesis. Pancreatic beta cells are involved in insulin production, gastric parietal cells secrete gastric acid, and neurons and glial cells are part of the nervous system.

4. An imbalance of which of the following hormones could lead to increased calcium levels in the blood?

Correct answer: A

Rationale: The correct answer is Parathyroid hormone (Choice A). Parathyroid hormone plays a key role in regulating calcium levels in the blood. When there is an imbalance in parathyroid hormone secretion, it can lead to increased calcium levels in the blood. Antidiuretic hormone (Choice B) is involved in regulating water balance, not calcium levels. Calcitonin (Choice C) helps lower blood calcium levels and is unlikely to cause an increase. Melatonin (Choice D) regulates sleep-wake cycles and does not have a direct effect on calcium levels in the blood.

5. After sustaining a concussion, a client experiences headache, vomiting, blurred vision, and loss of consciousness. What does this indicate?

Correct answer: A

Rationale: The symptoms of headache, vomiting, blurred vision, and loss of consciousness following a concussion are indicative of increased intracranial pressure. These symptoms are commonly associated with intracranial pressure elevation, which can be dangerous and requires immediate medical attention. Lower extremity compartment syndrome is characterized by severe pain and swelling in the affected limb, not the symptoms mentioned. Consuming too much food at once may lead to digestive issues but does not correlate with the symptoms described. Improved kidney function would not manifest through the symptoms mentioned after a concussion.
