Correct Answer: B

Rationale: Monitoring the client's respiratory rate and effort is essential to evaluate the effectiveness of oxygen therapy and prevent complications such as respiratory depression. This intervention helps the nurse promptly detect any deterioration in the client's respiratory status and take necessary actions to ensure the client's safety. Encouraging continuous oxygen use (Choice A) may lead to oxygen toxicity. Setting the oxygen flow rate at a specific level (Choice C) without individual assessment can be inappropriate and potentially harmful. Teaching the client to avoid wearing wool blankets (Choice D) is unrelated to the safe use of oxygen therapy.

Correct Answer: A

Rationale: In the scenario where a nurse administers a medication outside the prescribed parameters, the immediate action should be to assess the client for any potential side effects of the medication. This is crucial to ensure the client's safety and well-being. By promptly assessing for side effects, the nurse can address any adverse reactions promptly and provide necessary interventions. Once the client's safety is ensured, documenting the client's responses, completing a medication error report, and assessing pain relief can follow as part of the broader response to the medication error. Choice B is not the first priority because the immediate concern is the potential harm from the incorrect dose. Choice C is also important but comes after ensuring the client's safety. Choice D focuses on the outcome rather than the immediate need to address any side effects of the medication.

Correct Answer: A

Rationale: Adolescents are particularly influenced by peers, so associating with non-smokers may help the student quit smoking. By being surrounded by non-smokers, the student is less likely to feel pressured to smoke and may be encouraged to adopt healthier behaviors. This intervention leverages the power of social influence to support smoking cessation efforts and create a more conducive environment for the student to quit smoking. Choices B, C, and D do not address the social aspect of smoking behavior and the influence of peers on smoking habits, making them less effective interventions in this case.

Correct Answer: A

Rationale: The most critical information for the nurse to obtain during the admission assessment of a client with severe pain due to breast cancer metastasis to the liver and spine is the sensory pattern, area, intensity, and nature of the pain. Understanding these details is essential to tailor appropriate pain management therapy effectively. By assessing the sensory pattern, area, intensity, and nature of pain, the nurse can better determine the underlying cause and choose the most suitable interventions to address the client's pain and improve their quality of life. Trigger points, medication dosages, and sympathetic responses are also important aspects of pain assessment but understanding the sensory aspects of pain is fundamental for providing optimal care in this scenario.

Correct Answer: B

Rationale: Kussmaul respirations (B) are a deep and labored breathing pattern associated with diabetic ketoacidosis (DKA) and are expected in this condition. While oliguria (A), fruity odor on the breath (C), and elevated blood glucose level (D) are also signs of DKA, Kussmaul respirations are more specific and critical to the condition, indicating severe metabolic acidosis.
