Correct Answer: A

Rationale: The correct signs of hypoglycemia are sweating and trembling. These should be managed by administering glucose to raise blood sugar levels. Headache, confusion, dizziness, fatigue, or increased heart rate are not typical signs of hypoglycemia. Administering insulin in response to hypoglycemia would further lower blood sugar levels, exacerbating the condition.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps maintain airway patency by preventing the collapse of small airways during exhalation, improving breathing efficiency. Administering oxygen at 2 L/min via nasal cannula may be appropriate for some COPD patients but is not the priority intervention. Positioning the client in high Fowler's position may help improve breathing but is not as specific as pursed-lip breathing for COPD. Encouraging deep breathing and coughing may be beneficial in other respiratory conditions, but it is not the most effective intervention for COPD.

Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the nurse's immediate action should be to discontinue the IV and notify the healthcare provider. Phlebitis is inflammation of the vein, and leaving the IV in place can lead to complications such as infection or thrombosis. Administering an anti-inflammatory medication (choice A) may not address the root cause and delay the necessary intervention. Applying a cold compress (choice C) may provide temporary relief but does not address the need to remove the source of inflammation. Increasing the IV flow rate (choice D) is contraindicated as it can exacerbate the phlebitis by causing more irritation to the vein.

Correct Answer: B

Rationale: Confusion, especially about one's own name, is a sign of increased intracranial pressure and should be addressed. Nausea and vomiting are common symptoms of increased intracranial pressure, but confusion about personal information is a more specific and critical indication that requires immediate attention. Rapid pulse may be a possible response to increased intracranial pressure, but it is not as specific as confusion about own name in this scenario.

Correct Answer: B

Rationale: The correct answer is B: 'Check for air leaks and ensure proper chest tube function.' This is the most important assessment for a client with a chest tube post-surgery because it ensures that the chest tube is functioning properly. Checking for air leaks helps prevent complications such as pneumothorax or hemothorax. Choice A is incorrect because clamping the chest tube periodically can lead to serious complications and should not be done unless specifically ordered by a healthcare provider. Choice C is important for promoting lung expansion but is not the most critical assessment related to the chest tube. Choice D is also important for respiratory function but is not the priority when assessing a chest tube post-surgery.
