Correct Answer: B

Rationale: The correct answer is to administer antibiotics as prescribed. Antibiotics are the primary treatment for urinary tract infections as they help eliminate the bacteria causing the infection. Encouraging the patient to increase fluid intake (Choice A) is a supportive measure to help flush out the bacteria but doesn't directly treat the infection. Over-the-counter pain relievers (Choice C) may help with discomfort but do not address the underlying infection. Limiting physical activity (Choice D) may be recommended for some conditions but is not the primary intervention for treating a UTI.

Correct Answer: D

Rationale: Corrected Rationale: When a patient is prescribed a diuretic for hypertension, monitoring the patient's sodium levels is crucial. Diuretics can lead to alterations in sodium levels, potentially causing complications like hyponatremia. While monitoring other parameters like respiratory rate, blood pressure, and potassium levels may also be important, the primary concern with diuretic therapy is the risk of sodium imbalance, making the monitoring of sodium levels the most critical assessment.

Correct Answer: B

Rationale: During chemotherapy, hair loss is a common side effect. Offering resources for wigs and head coverings can help the client cope with this change in appearance, maintain self-esteem, and feel more comfortable during the process. Encouraging the client to cut their hair short does not address the emotional impact of hair loss and may not be the client's preference. Assuring the client that hair loss will be minimal may provide false hope as significant hair loss is a common occurrence. Ignoring the client's concerns is not appropriate and goes against the principles of providing holistic and compassionate care.

Correct Answer: B

Rationale: Administering oxygen via nasal cannula as prescribed is the most appropriate action to improve the patient's oxygenation in COPD. Oxygen therapy helps maintain adequate oxygen levels in the blood, which is crucial for managing COPD. Encouraging the use of incentive spirometry, assisting with coughing and deep breathing exercises, and positioning the patient in high Fowler's position are all beneficial interventions, but administering oxygen is the priority for immediate oxygenation support in COPD.

Correct Answer: B

Rationale: The correct answer is B. Nurses have a legal and ethical obligation to honor a client's do-not-resuscitate (DNR) order, regardless of any request for resuscitation during a family visit. It is crucial for the nurse to explain to the client that the DNR order must be respected. Choice A is incorrect because starting resuscitation against the client's documented wishes goes against the principle of autonomy. Choice C is inappropriate as it disregards the client's autonomy and legal directives. Choice D is not the best option as the nurse should prioritize honoring the client's decision as per the DNR order.
