Correct Answer: C

Rationale: The correct answer is C: 'Eat small, frequent meals.' Eating small, frequent meals helps manage IBS symptoms by avoiding overloading the digestive system. Choice A is incorrect because increasing fiber intake may worsen symptoms in some individuals with IBS. Choice B is not a blanket recommendation for all IBS patients; some may tolerate dairy products well. Choice D is incorrect as fruits and vegetables are important sources of nutrients and should not be completely avoided unless specific triggers are identified.

Correct Answer: D

Rationale: The correct answer is D because taking pain medication at regular intervals helps maintain consistent pain control after surgery. Option A is incorrect because waiting for the pain to become unbearable can lead to inadequate pain management. Option B is incorrect as it suggests increasing medication without a schedule. Option C is incorrect because waiting for the pain to be severe before taking medication is not proactive pain management.

Correct Answer: A

Rationale: The correct answer is A: Chest pain, shortness of breath, and tachycardia. These are classic early signs of a pulmonary embolism. Chest pain may be sudden and sharp, worsened by deep breathing or coughing. Shortness of breath can be sudden and severe. Tachycardia (rapid heart rate) is another common symptom. Choices B, C, and D are incorrect as they do not represent typical early signs of a pulmonary embolism.

Correct Answer: B

Rationale: The correct intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff when the client tries to leave the bed. This intervention helps prevent falls while still allowing some freedom of movement. Choice A is incorrect because using restraints can lead to complications and is considered a form of restraint which should be avoided. Choice C is not suitable for a client at high risk of falls due to dementia as it may increase the risk of falls. Choice D is not recommended as raising all four side rails can be considered a form of physical restraint and may not be the best approach to prevent falls in a client with dementia.

Correct Answer: C

Rationale: The most appropriate position for a client post-lumbar puncture is the supine position. Placing the client in a supine position helps prevent spinal headaches by allowing the puncture site to seal effectively and reducing the risk of cerebrospinal fluid leakage. High Fowler's position, prone position, and sitting position are not recommended after a lumbar puncture as they may increase the risk of complications like spinal headaches.
