When caring for a patient with Alzheimer's disease, the nurse would assess the patient for which two common infection-related complications due to chronic dementia?

Choice A reason: Hypoglycemia typically presents with symptoms such as sweating, trembling, hunger, confusion, and in severe cases, loss of consciousness. The patient's symptoms of sudden right-sided weakness and difficulty speaking are more consistent with a neurological event rather than low blood sugar levels.

Choice B reason: Hemorrhagic stroke involves bleeding within the brain. Although it can present with similar symptoms to ischemic stroke, the diagnostic tests indicate no evidence of hemorrhage. This makes a hemorrhagic stroke less likely.

Choice C reason: Ischemic stroke occurs when a blood clot blocks a blood vessel in the brain, leading to reduced blood flow and oxygen to a part of the brain. The patient's symptoms of sudden right-sided weakness and expressive aphasia are classic signs of an ischemic stroke, and the absence of hemorrhage on the head CT scan supports this diagnosis.

Choice D reason: Multiple sclerosis (MS) is a chronic, progressive disease that affects the central nervous system. It usually presents with episodic neurological symptoms rather than the sudden onset seen in this patient. MS symptoms develop over time and can vary widely, whereas the patient's acute presentation is more indicative of a stroke.

Choice A reason: Encouraging the patient to engage in strenuous exercise to improve circulation is not appropriate for someone with thrombocytopenia. Strenuous exercise can increase the risk of injury and bleeding, which is particularly dangerous for patients with a low platelet count.

Choice B reason: Instructing the patient to use an electric razor for shaving is the most appropriate intervention. Thrombocytopenia increases the risk of bleeding, and using an electric razor instead of a traditional blade helps minimize the risk of cuts and subsequent bleeding.

Choice C reason: Teaching the patient to use a water pick for oral hygiene is not recommended for thrombocytopenia patients. Water picks can cause bleeding of the gums, which is a concern for individuals with low platelet counts. Using a soft-bristled toothbrush is safer.

Choice D reason: Requesting an order for subcutaneous heparin to prevent blood clots is not advisable for a thrombocytopenia patient without specific medical indication. Heparin is an anticoagulant, and administering it to someone with low platelets can exacerbate the risk of bleeding.
