1. What is the most likely cause of continuous bubbling in the water seal chamber of a chest tube?

A. An air leak
B. A blockage in the chest tube
C. Normal chest tube function
D. Drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube usually indicates an air leak. An air leak can disrupt the negative pressure required for the chest tube to function properly, leading to inadequate drainage and potential complications. A blockage in the chest tube would typically result in decreased or absent drainage rather than continuous bubbling. Normal chest tube function does not involve continuous bubbling in the water seal chamber. Drainage from the chest tube may lead to fluid moving into the drainage system, but it would not cause continuous bubbling in the water seal chamber.

2. What teaching should be provided after cataract surgery?

A. Avoid NSAIDs
B. Wear dark glasses outdoors
C. Creamy white drainage is normal
D. Avoid bright lights

Correct answer: A

Rationale: The correct teaching that should be provided after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to prevent bleeding, especially in the eye area. While wearing dark glasses outdoors is important to protect the eyes, it is not the most critical teaching after cataract surgery. Creamy white drainage being normal is not relevant to post-cataract surgery teaching. Avoiding bright lights is generally recommended for patients with certain eye conditions but is not a specific teaching point after cataract surgery.

3. What are the signs and symptoms of Increased Intracranial Pressure (IICP)?

A. Irritability, confusion, restlessness
B. Fatigue and SOB
C. Changes in pupillary response
D. Elevated blood pressure

Correct answer: A

Rationale: The correct answer is A: Irritability, confusion, restlessness. These are common signs of Increased Intracranial Pressure (IICP) as they result from the increased pressure on brain tissue. Choices B, C, and D are incorrect. Fatigue and shortness of breath (SOB) are not typical symptoms of IICP. Changes in pupillary response can be seen in other conditions but are not specific to IICP. Elevated blood pressure is not a common sign of IICP.

4. A nurse is providing discharge teaching for a client who has COPD about nutrition. Which of the following instructions should the nurse include?

A. Eat three large meals daily
B. Consume high-calorie foods
C. Limit caffeinated drinks to two per day
D. Drink fluids during meal time

Correct answer: B

Rationale: The correct answer is B: 'Consume high-calorie foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach putting pressure on the diaphragm. Choice C is incorrect because caffeinated drinks can contribute to dehydration, which is not ideal for clients with COPD. Choice D is incorrect because drinking fluids during mealtime can cause bloating and early satiety, making it difficult for clients to consume enough calories.

5. How does hyponatremia place the patient at risk?

A. Seizures
B. Fatigue
C. Cardiac dysrhythmias
D. Muscle weakness

Correct answer: C

Rationale: Hyponatremia places the patient at risk for cardiac dysrhythmias. While hyponatremia can lead to seizures due to cerebral edema caused by fluid imbalance, the most immediate and life-threatening risk is cardiac dysrhythmias. Low sodium levels can disrupt the heart's electrical activity, potentially leading to fatal arrhythmias. Although fatigue and muscle weakness are symptoms of hyponatremia, cardiac dysrhythmias pose the most critical concern as they can have severe consequences.
