Correct Answer: C

Rationale: The correct answer is C: 'Use cotton fabrics when oxygen is in use.' When a client is on oxygen therapy, it is essential to use cotton fabrics to reduce the risk of static electricity, which can ignite in the presence of oxygen. Choices A, B, and D are incorrect. Removing the oxygen tubing during meals is not necessary as long as proper precautions are taken to avoid tripping hazards. Synthetic fabrics should be avoided while using oxygen therapy to prevent static electricity buildup. Increasing oxygen flow during physical activity should be done according to the healthcare provider's instructions, not indiscriminately.

Correct Answer: B

Rationale: The correct answer is B: 'Peer pressure can lead to risky behaviors.' Adolescents are at an increased risk for injury due to peer pressure and the tendency to engage in high-risk behaviors. Emphasizing the impact of peer pressure on decision-making can help adolescents make safer choices. Choices A, C, and D are incorrect because adolescents actually have an increased risk of injury, increased responsibility does not always reduce risks, and many adolescents are at risk of engaging in substance abuse.

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: C

Rationale: The correct action for the nurse to take when administering medications to a client with dysphagia is to place the medications in small amounts of pudding. Mixing medications with pudding helps clients with dysphagia swallow them more easily. Choice A (crushing medications and mixing with honey) is not recommended as it may alter the medication properties. Choice B (providing medications through a straw) is not suitable for clients with dysphagia as it can pose a choking hazard. Choice D (offering medications with a full glass of water) may be difficult for clients with dysphagia to swallow and increase the risk of aspiration.

Correct Answer: B

Rationale: Frequent urge suppression can lead to constipation, especially postoperatively. Suppressing the urge to defecate can disrupt normal bowel movements and result in constipation. Increased physical activity, increased fiber intake, and adequate fluid intake are measures that typically help prevent constipation by promoting bowel regularity and preventing stool hardening. Therefore, choices A, C, and D are not behaviors that increase the client's risk for constipation.
