Correct Answer: B

Rationale: The correct lifestyle modification that the nurse should emphasize for a client with hypertension is to increase fluid intake to 2 liters per day. Proper hydration helps manage hypertension by supporting kidney function in regulating blood pressure and by diluting sodium levels in the body. Decreasing potassium intake (Choice A) is not recommended, as potassium-rich foods like fruits and vegetables are beneficial for blood pressure control. Avoiding foods high in calcium (Choice C) is not directly related to managing hypertension, and increasing sodium intake (Choice D) is contraindicated as excess sodium can elevate blood pressure.

Correct Answer: B

Rationale: Verifying tube placement is the crucial initial step a nurse should take before administering enteral feedings through an NG tube. This step ensures that the tube is correctly positioned in the stomach, reducing the risk of complications such as aspiration. Measuring residual gastric volume, flushing the tube with water, or administering the feeding in small boluses are all important steps in enteral feeding but should only be done after confirming the correct tube placement.

Correct Answer: B

Rationale: When a client reports pain at the site of an indwelling urinary catheter, the nurse's first action should be to notify the provider. This is important to ensure timely assessment and intervention by the healthcare provider. Irrigating the catheter with normal saline or administering antibiotics should not be done without provider's orders as it may mask symptoms or lead to inappropriate treatment. Assessing for signs of infection is important but should come after notifying the provider, who can guide further assessment and treatment.

Correct Answer: C

Rationale: The correct answer is C: Perform weight-bearing exercises. Weight-bearing exercises help maintain bone density and reduce the risk of osteoporosis in older adults. Choice A, increasing intake of vitamin C, is not directly related to osteoporosis prevention. Choice B, avoiding weight-bearing exercises, is incorrect as weight-bearing exercises are beneficial for bone health. Choice D, limiting sun exposure, is not a key factor in osteoporosis prevention as moderate sun exposure is important for vitamin D synthesis which is essential for bone health.

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes at all times.' This instruction is crucial for clients with diabetes as it helps protect the feet from potential injuries. Choice A of soaking feet in warm water daily can lead to skin issues and should be avoided. Cutting toenails in a rounded shape, as mentioned in choice C, can increase the risk of ingrown toenails. While inspecting the feet weekly, as in choice D, is important, wearing shoes at all times is a more preventative measure to avoid foot injuries in diabetic clients.
