Correct Answer: B

Rationale: The correct answer is B: 'Contact your provider if you experience visual changes.' Visual changes, such as blurred or yellow vision, can indicate digoxin toxicity and should be reported immediately to the healthcare provider for further evaluation and management. Choice A is incorrect because digoxin can be taken with antacids. Choice C is incorrect because increasing potassium intake can lead to hyperkalemia when taking digoxin. Choice D is incorrect because increased urination is not a common side effect of digoxin.

Correct Answer: B

Rationale: Thrombophlebitis is a condition characterized by inflammation of a vein, which increases the risk of blood clots. The use of oral contraceptives further elevates the risk of clot formation, making them contraindicated in individuals with thrombophlebitis. Hyperthyroidism (Choice A), diverticulosis (Choice C), and hypocalcemia (Choice D) are not contraindications to the use of oral contraceptives.

Correct Answer: A

Rationale: The correct answer is A. Lisinopril can increase potassium levels, so clients should avoid salt substitutes that contain potassium. Choice B is incorrect because lisinopril is usually taken on an empty stomach. Choice C is incorrect because lisinopril can lead to hyperkalemia, so increasing potassium-rich foods is not recommended. Choice D is incorrect because lisinopril can cause increased urination, so fluid intake should not be limited.

Correct Answer: A

Rationale: The correct answer is A: Constant bubbling in the water seal chamber. Constant bubbling in the water seal chamber can indicate an air leak, which compromises the integrity of the chest tube system and should be reported to the provider for immediate intervention. Choices B, C, and D are incorrect. Intermittent bubbling in the suction control chamber is an expected finding indicating that the system is working appropriately. Tidaling in the water seal chamber is a normal fluctuation of fluid level with inspiration and expiration, indicating that the system is functioning correctly. Drainage of 75 mL in the first 24 hours is within the expected range for chest tube drainage and does not require immediate reporting unless accompanied by other concerning symptoms.

Correct Answer: A

Rationale: A positive Trousseau's sign is a key finding in clients with hypocalcemia, indicating neuromuscular irritability. The other choices are not typically associated with hypocalcemia. Increased deep tendon reflexes are more indicative of hypercalcemia. Hyperactive bowel sounds can be seen in hyperactive bowel conditions or diarrhea, not specifically related to hypocalcemia. A weak, thready pulse may indicate cardiovascular issues, such as dehydration, but it is not a typical finding in hypocalcemia.
