Correct Answer: A

Rationale: Weight gain is an expected finding in hypothyroidism due to the decreased metabolic rate. Hypothyroidism leads to a slowing down of bodily functions, including metabolism, which can result in weight gain. Weight loss (
Choice
B) is more commonly associated with hyperthyroidism where there is an increase in metabolic rate. Increased appetite (
Choice
C) is also more typical of hyperthyroidism as the body is burning energy at a faster rate. Diarrhea (
Choice
D) is not a typical symptom of hypothyroidism; instead, constipation is more often observed due to the slowing down of the digestive system.

Correct Answer: B

Rationale: The most appropriate intervention for a patient with acute pancreatitis is administering IV fluids. IV fluid administration is crucial in managing acute pancreatitis as it helps maintain hydration, correct electrolyte imbalances, and prevent shock. Administering oral fluids (
Choice
A) may not be sufficient to address the fluid loss and maintain hydration in these patients. While analgesics (
Choice
C) are important for pain management in pancreatitis, addressing hydration and shock prevention takes precedence. Encouraging the patient to ambulate (
Choice
D) may be beneficial in some cases for preventing complications like deep vein thrombosis, but it is not the primary intervention needed in the acute phase of pancreatitis.

Correct Answer: A

Rationale: The correct answer is A: Showing the location of the obstruction and the collateral circulation. An arteriogram is a diagnostic procedure that involves injecting a contrast agent to visualize the blood vessels and identify the location of any obstructions. This helps confirm the diagnosis of occlusive arterial disease by showing where the blockage is located and how collateral circulation is compensating for the reduced blood flow.

Choices B, C, and D are incorrect because scanning the extremity, estimating velocity changes with ultrasound, or determining walking distance are not the primary purposes of an arteriogram in diagnosing occlusive arterial disease.

Correct Answer: B

Rationale: The correct answer is B: Bananas. Bananas are high in potassium, which should be limited in clients with chronic renal failure to prevent hyperkalemia. Apples (choice
A), chicken (choice
C), and rice (choice
D) are not typically restricted in clients with chronic renal failure. Apples and rice are lower in potassium, while chicken is a good source of lean protein, which is usually encouraged in these clients to meet their protein needs without excess potassium intake.

Correct Answer: D

Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (
Choice
A) and burning pain (
Choice
B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (
Choice
C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.
