Correct Answer: A

Rationale: The correct answer is A. In older adults, key signs of a UTI often include confusion and increased temperature. Confusion is a common symptom in the elderly when they have a UTI, and an increase in body temperature can indicate an infection. Choices B, C, and D are incorrect because while painful urination and frequent urination are common UTI symptoms in general, they may not be as prominent in older adults. Dizziness, headache, back pain, and fever can be associated with other conditions but are not typically key signs of a UTI in older adults.

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: D

Rationale: The correct answer is to increase calcium intake to 1,500 mg per day. Adequate calcium intake is essential for maintaining bone density and reducing the risk of osteoporosis. Walking for at least 30 minutes each day is beneficial for overall health but is not as directly related to osteoporosis prevention as calcium intake. Sunlight exposure is important for vitamin D synthesis, which is necessary for calcium absorption, so avoiding sunlight exposure would not be recommended. Vitamin B12 supplements are not directly related to bone health or osteoporosis prevention, so this would not be the most appropriate recommendation.

Correct Answer: B

Rationale: The correct first action for a client with a tracheostomy exhibiting signs of respiratory distress is to suction the tracheostomy. This helps clear the airway and improve breathing. Increasing the suction setting on the ventilator is not appropriate as the issue may be related to secretions that need to be directly removed. Notifying the physician should come after providing immediate nursing interventions. Encouraging deep breathing exercises is not suitable when the client is in respiratory distress and needs prompt intervention.

Correct Answer: D

Rationale: The correct action for the nurse to take when preparing to insert an indwelling urinary catheter is to open the catheterization kit away from the body. This is crucial to maintain the sterility of the kit and the procedure. Using sterile gloves (Choice A) is important, but it is not specific to this step. Lubricating the catheter with water (Choice B) is incorrect as it should be lubricated with a water-soluble lubricant. Inserting the catheter using clean technique (Choice C) is incorrect as indwelling urinary catheter insertion requires sterile technique to prevent infections.
