Correct Answer: C

Rationale: A blood glucose level of 200 mg/dL indicates hyperglycemia and should be reported for potential insulin adjustment.

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.

Correct Answer: A

Rationale: The correct answer is A: Bananas. Bananas are high in potassium, which should be limited in clients with heart failure to prevent electrolyte imbalances. While leafy green vegetables and whole grains are generally healthy options, they are not typically restricted in heart failure patients. Potatoes, although they contain potassium, are not as high in potassium as bananas and are not usually restricted as strictly.

Correct Answer: C

Rationale: The correct instruction for the nurse to include is to schedule a bone density test. Prednisone can lead to reduced bone density, making regular monitoring crucial for clients on long-term therapy. Instructing the client to take the medication with food (choice A) or avoid taking aspirin (choice B) are not directly related to prednisone therapy for Addison's disease. While prednisone can cause increased appetite, it is not the priority instruction in this scenario, compared to monitoring bone density (choice D).

Correct Answer: B

Rationale: The correct answer is B: 'Keep the oxygen equipment away from heat sources.' Placing oxygen equipment near heat sources can lead to fire hazards due to the flammability of oxygen. Cotton bedding or wool blankets are not directly related to oxygen safety measures. Allowing electronic devices near the oxygen supply can increase the risk of fire due to potential sparks or heat generated.
