A nurse is teaching a client who has asthma about how to use a metered-dose inhaler with a spacer. Which of the following pieces of information should the nurse include in the teaching?

Choice A reason: A client with diabetes mellitus presenting with acute ketoacidosis does not necessarily require a private room unless there are other infection control concerns. Acute ketoacidosis is a metabolic complication of diabetes that can be managed in a general ward setting with appropriate medical care and monitoring.

Choice B reason: An older adult client admitted with aspiration pneumonia would benefit from a private room if the pneumonia is caused by an infectious agent that requires droplet or airborne precautions. However, aspiration pneumonia is often a result of inhaling food, stomach acid, or saliva into the lungs, and not always infectious.

Choice C reason: A client with a compound fracture of the right femur would require a private room if there is an associated risk of infection due to the open nature of the injury. However, standard precautions and wound care can often be managed in a semi-private or general ward setting unless there are specific infection control issues.

Choice D reason: A client reporting fever, night sweats, and cough for 2 days may be exhibiting symptoms of a communicable disease such as tuberculosis. This client would require a private room with airborne precautions to prevent the spread of infection to other patients and healthcare workers.

Choice A reason: Encouraging family members to press the PCA button for the client is not recommended. The PCA device is designed to be used by the patient to manage their own pain. Allowing someone other than the patient to administer the medication can lead to over-sedation or respiratory depression. The patient must have control over the PCA device to ensure that they are receiving the medication based on their pain level and not someone else's perception of their pain.

Choice B reason: Monitoring the client's respiratory status every 4 hours is important but may not be sufficient for a patient receiving morphine via a PCA device. According to clinical guidelines, respiratory rate, sedation, and pain scores must be recorded more frequently after the initiation of PCA therapy—typically every 15 minutes for the first hour, then every 30 minutes for the next 2 hours, and hourly until 24 hours post-operation. This is to ensure early detection of any adverse effects such as respiratory depression, which is a risk with opioid administration.

Choice C reason: Teaching the client how to self-medicate using the PCA device is the correct action. Patient education is crucial for the effective use of PCA. The patient should be instructed on how to use the device, including when to press the button and the importance of only the patient controlling the button. This empowers the patient to manage their pain effectively and safely, ensuring that they receive the medication when needed and reducing the risk of over-sedation or under-medication.

Choice D reason: Administering an oral opioid for breakthrough pain may be necessary if the PCA does not adequately control the patient's pain. However, this should be done cautiously and typically under the guidance of a pain management team or physician. Breakthrough pain medication is usually reserved for instances where the PCA is not providing sufficient pain relief, and the patient's pain is assessed to be higher than what can be managed by the PCA alone.
