1. Which organ produces and secretes bicarbonate ions and insulin?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: B

Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.

2. The type of medicine that proposes that a person's inherent "life force" can foster self-healing is known as _____ medicine.

• A. homeopathic
• B. integrative
• C. naturopathic
• D. Ayurvedic

Correct answer: C

Rationale: Naturopathic medicine is based on the belief that a person's inherent "life force" can promote self-healing, often using natural therapies and lifestyle changes.

3. What is the most likely demonstration of cardiac cachexia?

• A. Decreased physical activity
• B. Weight loss and tissue wasting
• C. Poor urine output and tissue edema
• D. Cardiac arrhythmia and wet lung sounds

Correct answer: B

Rationale: Cardiac cachexia is a condition characterized by severe weight loss and tissue wasting. This typically occurs in patients suffering from heart failure due to an increased energy expenditure and reduced appetite, which is why choice B is the correct answer. The other choices are incorrect as they do not accurately describe the symptoms of cardiac cachexia. Decreased physical activity (choice A) can be a result of many conditions, not specifically cardiac cachexia. Poor urine output and tissue edema (choice C) are more indicative of kidney problems rather than cardiac cachexia. Finally, cardiac arrhythmia and wet lung sounds (choice D) are symptoms related to other cardiac conditions, not specifically to cardiac cachexia.

4. A client receiving total parenteral nutrition (TPN) suddenly develops tremors, dizziness, and diaphoresis. The client said, 'I feel weak and the bag was empty.' Which is the most likely complication the client is currently experiencing?

• A. Fluid volume overload
• B. Sepsis
• C. Hyperglycemia
• D. Hypoglycemia

Correct answer: D

Rationale: The client experiencing tremors, dizziness, diaphoresis, weakness, and stating that the TPN bag is empty is likely experiencing hypoglycemia. Hypoglycemia can occur when the TPN infusion suddenly stops, leading to a rapid drop in blood sugar levels. Symptoms of hypoglycemia include tremors, dizziness, diaphoresis, and weakness. Choices A, B, and C are incorrect as the symptoms presented are more consistent with hypoglycemia rather than fluid volume overload, sepsis, or hyperglycemia.

5. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
