Which instruction will the nurse plan to include in discharge teaching for a patient who was admitted with a sickle cell crisis?

Choice A reason: While CT or MRI scans can be helpful in identifying structural changes in the brain associated with dementia, such as atrophy or the presence of strokes, they are not sufficient on their own to diagnose dementia. These imaging techniques are often used to rule out other causes of cognitive impairment and to support a clinical diagnosis, but they do not provide a complete picture of a patient's cognitive function.
Choice B reason: Patient history and cognitive assessment are the primary methods for diagnosing dementia. The clinical diagnosis is based on a thorough evaluation of the patient's medical history, including any changes in cognitive function, behavior, and daily living activities. Cognitive assessments, such as the Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA), are used to evaluate memory, attention, language, and other cognitive abilities. These assessments help to determine the presence and severity of cognitive impairment and differentiate dementia from other conditions that may cause similar symptoms.
Choice C reason: A brain biopsy is not a standard procedure for diagnosing dementia. It is an invasive procedure that involves taking a small sample of brain tissue for examination under a microscope. While it can provide definitive information about certain types of dementia, such as Creutzfeldt-Jakob disease, it is rarely used due to its invasiveness and associated risks.
Choice D reason: An electroencephalogram (EEG) is a test that measures electrical activity in the brain. It can be useful in diagnosing certain neurological conditions, such as epilepsy, but it is not typically used to diagnose dementia. EEGs do not provide detailed information about cognitive function or the structural changes in the brain associated with dementia.

Choice A reason: Asking the HCP to change the medication from heparin to enoxaparin (Lovenox) would not be the most appropriate action for a patient diagnosed with heparin-induced thrombocytopenia (HIT). Enoxaparin, like heparin, is a low molecular weight heparin and can still cause HIT. Therefore, this action does not address the immediate need to stop the heparin infusion to prevent further reduction in platelet levels and manage the HIT effectively.
Choice B reason: Discontinuing the heparin infusion is the correct action for a nurse to take first when a patient is diagnosed with heparin-induced thrombocytopenia (HIT). The primary step in managing HIT is to stop all forms of heparin to prevent further platelet activation and decrease in platelet count. Discontinuing heparin helps to prevent thromboembolic complications associated with HIT. Once heparin is discontinued, the healthcare provider can evaluate alternative anticoagulation therapies that do not cross-react with heparin, such as direct thrombin inhibitors.
Choice C reason: Administering prescribed warfarin (Coumadin) is not appropriate at this stage for a patient diagnosed with heparin-induced thrombocytopenia (HIT). Warfarin can initially lead to a hypercoagulable state, which increases the risk of thrombosis in patients with HIT. The immediate priority is to discontinue heparin, and warfarin should only be considered once platelet counts have recovered and the acute HIT has been managed.
Choice D reason: Preparing for platelet transfusion is not the first action to take for managing heparin-induced thrombocytopenia (HIT). Platelet transfusions are generally avoided in HIT as they can potentially worsen the thrombotic risk. The primary action should be to discontinue heparin and consider alternative anticoagulation therapies. Platelet transfusions may be reserved for cases where there is significant bleeding or invasive procedures are planned.
