me Remaining (Minutes): 33 The patient reports having a severe headache when taking nitroglycerin (Nitrostat ) for angina. The nurse tells the patient that the headache is caused by a. aura prior to a migraine headache. b. hypoglyemia. c. vasoconstriction of the cerebral arteries. Od. vasodilation of the cerebral arteries Which laboratory study is m0st important for the determination of both the most appropriate treatment regimen and the assessment of the effectiveness of treatment for a patient with infectious endocarditis? Oa. Blood cultures b. Complete blood count (CBC) c. D-dimer d. Erythrocyte sedimentation rate (ESR) A 64-year-old female patient is brought to the Emergency Department because she demonstrates an alteration in reality marked by distorted perceptions, disorganized thinking. impaired judgment, impaired decision making, and regressive behavior. The emergency nurse notifies the provider that the patient is displaying a. delirium. b. dementia Oc psychosis d. schizophrenia A 46-year-old female patient presents to the Emergency Department with pleunitic chest pain. She has an allergy to IV contrast dye and a past medical history of deep vein thrombosis (DVT: she is not taking her prescribed anticoagulant. Her laboratory testing reveals an elevated D-dimer. For which diagnostic study does the emergency nurse anticipate preparing the patient? a. Chest X-Ray b. Computed Tomography (CT) of the Chest without IV contrast c. Magnetic Resonance Imaging (MRI) d. Ventilation/Perfusion Scan

Answers

Answer: d) vasodilation of cerebral arteries. (Nitroglycerine is a vasodilator as it dilates the coronary arteries, to increase the blood flow to the myocardial layer of the heart, it also at the same time dilates the cerebral blood vessels with causes a headache.)

Answer: a) blood cultures (Infective endocarditis (IE) is defined as an infection of the endocardial surface of the heart which may include one or more heart valves, the mural endocardium, or a septal defect. A blood culture helps identify the causative bacteria or fungi and approximate antibiotics that are sensitive to the causative agents can be administered.)

Answer: a) delirium (Since she is over 60 years of age, she is at higher risk of having developed delirium. The signs and symptoms of delirium are also distorted perceptions, disorganised thinking, impaired judgement, impaired decision making and regressive behavior.)

Answer: d) ventilation / perfusion scan (since the patient is in the emergency department with pleuritic chest pain she would be put on ventilation / perfusion scan. It is a scan that uses radioactive material to examine airflow and blood flow in the lungs.

The aim of this scan is to look for evidence of any blood clot in the lungs.)
