A client is hospitalized for observation after suffering heat exhaustion during a marathon race. He complains of dizziness when he stands up, and the RN determines that he has postural hypotension. Based on the information, which of the following electrolyte imbalances could cause the client's symptoms?

Choice A reason: This is not the correct answer because offering to notify the health care provider after morning rounds are completed is not the first action that the critically thinking nurse should take. The nurse should act promptly and advocate for the patient's pain management needs, rather than delaying the communication with the health care provider.

Choice B reason: This is the correct answer because exploring other options for pain relief is the first action that the critically thinking nurse should take. The nurse should assess the patient's pain level, location, quality, and contributing factors, and use a multimodal approach to pain management that includes pharmacological and non-pharmacological interventions, such as ice, heat, distraction, relaxation, or massage.

Choice C reason: This is not the correct answer because discussing the surgical procedure and reason for the pain is not the first action that the critically thinking nurse should take. The nurse should focus on alleviating the patient's pain, rather than educating the patient about the surgery. The nurse can provide information and reassurance to the patient after the pain is controlled.

Choice D reason: This is not the correct answer because explaining to the patient that nothing else has been ordered is not the first action that the critically thinking nurse should take. The nurse should not dismiss the patient's pain or imply that the patient has no other options for pain relief. The nurse should collaborate with the patient and the health care provider to find the best pain management plan for the patient.

Choice A reason: Encouraging the patient to wait for 24 hours before applying new knowledge is not an effective strategy to promote learning. It may cause the patient to forget or lose interest in the information. The RN should encourage the patient to apply new knowledge as soon as possible to reinforce learning and improve retention.

Choice B reason: Organizing the content from complex to simple is not an effective strategy to promote learning. It may confuse or overwhelm the patient with too much information at once. The RN should organize the content from simple to complex, starting with the most essential and relevant information and building on it gradually.

Choice C reason: Repeating the key concepts is an effective strategy to promote learning. It helps the patient to remember and recall the important information and clarify any misunderstandings. The RN should repeat the key concepts at the beginning, during, and at the end of the lesson.

Choice D reason: Asking the patient to hold questions until after the lesson is completed is not an effective strategy to promote learning. It may discourage the patient from asking questions or expressing concerns that may affect their learning. The RN should encourage the patient to ask questions at any time and provide feedback and answers.
