The nurse is caring for a client diagnosed with leukemia who has just completed a course of radiation therapy and chemotherapy in preparation for a bone marrow transplant. The nurse notices that the client is febrile, has foul smelling urine, and is complaining of urinary frequency and dysuria. What is the priority nursing action?

A. An ischemic stroke occurs when a blood vessel supplying blood to the brain is obstructed. Common symptoms include sudden numbness or weakness in the face, arm, or leg, confusion, difficulty speaking, and visual disturbances. However, "thunderclap" headache and neck stiffness are not typical symptoms of an ischemic stroke.
B. A TIA, often referred to as a "mini-stroke," produces similar symptoms to a stroke but lasts for a short duration (typically less than 24 hours) and does not cause permanent damage. Symptoms can include weakness, speech difficulties, and visual changes, but again, "thunderclap" headache and neck stiffness are not characteristic of a TIA.
C. A subarachnoid hemorrhage occurs when there is bleeding into the space between the brain and the tissues covering it, often due to a ruptured aneurysm. A "thunderclap" headache, described as an extremely sudden and severe headache, is a hallmark of this condition.
D. A cardioembolic stroke is a type of ischemic stroke that occurs when a blood clot forms in the heart and travels to the brain. Symptoms are similar to those of an ischemic stroke and do not typically include a "thunderclap" headache or neck stiffness.

A. While it's important to monitor the surgical dressing, changing it too frequently can increase the risk of infection and disrupt healing. Instead, nurses typically assess the dressing regularly and only change it if it's overly saturated or if ordered by a physician. It’s essential to follow specific protocols regarding dressing changes.
B. A While breast prostheses can be an important part of post-mastectomy care for some clients, it is usually recommended that clients wait until they have fully healed and received counseling regarding their options. Immediate encouragement may be premature, as physical and emotional adjustments take time after surgery.
C. This is an appropriate intervention. After axillary lymph node dissection, there is a risk of lymphedema in the affected arm. Placing a limb alert bracelet serves as a reminder to healthcare providers to avoid taking blood pressure or performing venipunctures on the affected arm, thus helping prevent complications.
D. While PCA can be an effective method for managing postoperative pain, the timing and dosage should be based on the specific prescription and the client's individual needs. It’s crucial to educate the client about the PCA device and its use, but the specific interval may vary based on the medication's parameters and the patient's condition.
