When providing discharge teaching to a patient who underwent cataract surgery, what should the patient avoid?

A. Avoid NSAIDs

B. Avoid bright lights

C. Avoid alcohol

D. Avoid phosphorus-rich foods

Correct Answer: A
Rationale: The correct answer is to avoid NSAIDs. Nonsteroidal anti-inflammatory drugs (NSAIDs) can increase the risk of bleeding after cataract surgery due to their anticoagulant properties. Bright lights (choice B) are not contraindicated post-cataract surgery unless the patient experiences discomfort or sensitivity. Alcohol consumption (choice C) is generally not restricted after cataract surgery, but moderation is recommended. Phosphorus-rich foods (choice D) are not directly related to cataract surgery postoperative care.

What are the expected manifestations of a thrombotic stroke?

• A. Gradual loss of function on one side of the body
• B. Loss of sensation in the affected extremity
• C. Sudden loss of consciousness
• D. Seizures and convulsions

Correct Answer: A
Rationale: The correct answer is A: Gradual loss of function on one side of the body. Thrombotic strokes are caused by a clot forming in a blood vessel supplying the brain, leading to a gradual onset of symptoms due to impaired blood flow to specific brain regions. Choices B, C, and D are incorrect because loss of sensation, sudden loss of consciousness, seizures, and convulsions are not typically associated with thrombotic strokes. In a thrombotic stroke, the symptoms develop slowly over time, often over minutes to hours, and include manifestations such as weakness, numbness, or paralysis on one side of the body, along with other symptoms related to the affected brain area.

What does continuous bubbling in the chest tube water seal chamber indicate?

• A. An air leak
• B. Normal chest tube function
• C. A blocked chest tube
• D. Continuous drainage from the chest tube

Correct Answer: A
Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This occurs when air is entering the system from the outside, preventing the lung from fully re-expanding. Choice B is incorrect because continuous bubbling is not a sign of normal chest tube function. Choice C is incorrect because a blocked chest tube would typically exhibit no bubbling or fluctuation in the water seal chamber. Choice D is incorrect as continuous drainage would not cause bubbling in the water seal chamber.

What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct Answer: A
Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

What dietary changes should be implemented for a patient with GERD?

• A. Avoid mint and spicy foods
• B. Eat large meals before bedtime
• C. Consume liquids with meals
• D. Drink milk as a snack

Correct Answer: A
Rationale: The correct answer is A: Avoid mint and spicy foods. Patients with GERD should avoid mint and spicy foods because they can increase gastric acid production, exacerbating symptoms. Choice B is incorrect because eating large meals before bedtime can worsen GERD symptoms due to lying down with a full stomach. Choice C is incorrect as consuming liquids with meals can lead to increased pressure on the lower esophageal sphincter, promoting acid reflux. Choice D is also incorrect as drinking milk as a snack is not recommended for GERD patients, as it may temporarily soothe symptoms but can ultimately stimulate acid production.
