Which of the following is the correct method to reduce the risk of infection when handling a urinary catheter?

Correct Answer: B

Rationale: The correct method to reduce the risk of infection when handling a urinary catheter is to maintain sterile technique when inserting the catheter. Sterile technique helps prevent introducing pathogens into the urinary system, reducing the risk of infection. Choice A is incorrect because cleaning the catheter tubing with soap and water is not sufficient for preventing infection. Choice C is incorrect as clean gloves and technique are not enough; sterile technique is necessary. Choice D is incorrect as flushing the catheter tubing with sterile water, though important for maintaining catheter patency, does not address the need for sterile technique during insertion to prevent infection.

Correct Answer: B

Rationale: Providing the immobile patient with a special mattress is an effective way to prevent pressure ulcers. Special mattresses help distribute pressure evenly and reduce the risk of developing pressure ulcers by relieving pressure on sensitive areas. Turning the patient every 4 hours (Choice A) is a standard practice to prevent pressure ulcers but may not be as effective as using a special mattress. Elevating the patient's legs (Choice C) can help with circulation but may not directly prevent pressure ulcers. Limiting the patient's movement (Choice D) can lead to other complications and is not a recommended method for preventing pressure ulcers.

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 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: B

Rationale: The most appropriate method for assessing a patient's pain level is to use a standardized pain scale, such as a 0-10 scale. This method provides an objective and consistent way to measure and communicate the intensity of pain experienced by the patient. Choice A, observing facial expressions, can be subjective and may not always accurately reflect the level of pain. Choice C, asking the patient to rate their pain based on their mood, may be influenced by various factors unrelated to pain. Choice D, involving the patient's family members in assessing the pain, is not ideal as pain is a subjective experience that should be reported by the patient themselves.
