Correct Answer: B

Rationale: Correct Answer: B - Administer oxygen Rationale: 1. Oxygen therapy is crucial in managing COPD exacerbation to improve oxygen saturation levels. 2. Adequate oxygenation is essential to prevent further respiratory distress and potential complications. 3. Oxygen therapy helps alleviate symptoms like shortness of breath and fatigue, improving overall comfort. 4. Monitoring oxygen saturation levels guides the effectiveness of treatment and ensures appropriate oxygen delivery. Summary: - Administering corticosteroids (A) may help reduce inflammation in COPD exacerbation but does not address the immediate need for oxygen. - Monitoring respiratory rate (C) is important but prioritizing oxygen administration is more critical for immediate respiratory support. - Administering diuretics (D) may be indicated in certain cases of COPD exacerbation with fluid retention but is not the priority over oxygen therapy.

Correct Answer: B

Rationale: Mammography is used to detect tumors in the breast tissue. It is a screening tool for breast cancer. Tumors can be either benign or malignant. Mammograms help in early detection of abnormalities in breast tissue. Pain, edema, and epilepsy are unrelated to the purpose of mammography. Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder. Therefore, the correct answer is B because mammography is specifically designed to detect tumors in the breast.

Correct Answer: B

Rationale: The correct answer is B because moving the wheelchair close and pivoting on the unaffected extremity is the safest way to transfer a client with hemiparesis. This method minimizes strain on the affected side and reduces the risk of falls. First, ensure the wheelchair is positioned close to the bed. Then, assist the client to pivot by placing weight on the unaffected side and using proper body mechanics. This technique maintains stability and prevents injury. Choice A is incorrect because standing and walking the client to the wheelchair puts excessive strain on the affected side, increasing the risk of falls. Choice C is incorrect as pivoting on the affected extremity can lead to injury and instability. Choice D is incorrect as having the client stand and push to the wheelchair can be dangerous and may cause further harm.

Correct Answer: A

Rationale: The correct answer is A: Monitor urine output. This is the most important action because it helps assess the client's fluid status and kidney function. Monitoring urine output can indicate if the client's body is effectively eliminating excess fluid. Elevating the head of the bed (B) helps with respiratory function but is not the priority in fluid overload. Administering diuretics (C) may be necessary but should be based on urine output monitoring. Encouraging deep breathing (D) is important for respiratory function but not directly related to managing fluid overload.

Correct Answer: D

Rationale: The correct answer is D because when a client experiences an allergic reaction to a medication, the nurse should monitor for signs of infection as allergic reactions can sometimes lead to secondary infections. By closely monitoring the client for signs of infection, the nurse can promptly intervene and provide appropriate treatment. A: Discontinuing the medication is important but not the immediate priority when dealing with an allergic reaction. B: Notifying the healthcare provider is important, but monitoring for signs of infection takes precedence in this situation. C: Administering antihistamines may help with allergic symptoms but does not address the potential risk of secondary infection.
