A client being admitted with a transient ischemic attack reporting a headache is allergic to morphine, iodine, and codeine.
Which healthcare provider order should the nurse querry
Schedule a CT scan with contrast in the a.m.
Provide the client with a low-fat, low-cholesterol diet.
Take the client's vital signs per protocol.
Administer acetaminophen 650 mg PO for headache.
The Correct Answer is A
This scenario requires evaluating medical orders against a client's specific allergy profile to morphine, iodine, and codeine. Knowledge of hypersensitivity reactions to intravenous contrast media and the safe selection of analgesics is necessary to ensure patient safety and prevent potentially fatal allergic responses.
Choice A rationale
Iodine is a primary component of many intravenous contrast agents used in imaging. The client's documented iodine allergy necessitates questioning this order to avoid life-threatening systemic reactions, such as angioedema or airway obstruction, typically associated with radiopaque medium exposure.
Choice B rationale
Therapeutic lifestyle changes, including dietary modifications, are foundational in stroke prevention. Reducing dietary fats and cholesterol helps mitigate cardiovascular risk factors, supporting the long-term management of transient ischemic attacks without conflicting with the client's specific known drug allergies.
Choice C rationale
Protocol-based vital sign monitoring ensures the early detection of neurological or hemodynamic instability. This order is a standard of care for any patient presenting with cerebrovascular symptoms and carries no risk related to the client's iodine or opioid sensitivities.
Choice D rationale
Acetaminophen belongs to the para-aminophenol derivative class of medications. It does not possess the structural components of phenanthrene alkaloids like morphine or codeine, making it a safe alternative for treating mild to moderate pain in opioid-allergic individuals..

Correct Answer is A
Explanation
Neurological posturing indicates severe brain injury and helps localize the level of damage. Applying knowledge of motor pathway dysfunction, specifically the corticospinal tract, is necessary to distinguish between flexion and extension patterns seen in comatose patients.
Choice A rationale
Decorticate posturing results from damage to the corticospinal tract above the red nucleus. It is characterized by adduction of the arms, internal rotation, and flexion at the elbows, wrists, and fingers, while legs are extended and internally rotated.
Choice B rationale
This description does not match a standard neurological posturing pattern. Rigidity and flexion are seen in decorticate posturing, but "back hunched over" and "supination" of arms are not typical descriptors for these specific upper motor neuron indicators.
Choice C rationale
Supination of the arms is not a component of pathological posturing. Both decorticate and decerebrate posturing typically involve some form of pronation or flexion. Dorsiflexion is also not standard, as plantar flexion is commonly seen in both.
Choice D rationale
This describes decerebrate posturing, which indicates more severe damage to the brainstem or midbrain. It is characterized by rigid extension of the arms and legs, pronation of the arms, and plantar flexion of the feet with outward rotation.
Correct Answer is ["11.3"]
Explanation
Step 1 is 165 lb ÷ 2.2 lb/kg = 75 kg.
Step 2 is 75 kg × 0.3 mg/kg/hr = 22.5 mg/hr.
Step 3 is (22.5 mg/hr ÷ 500 mg) × 250 mL = 11.25 mL/hr.
Step 4 is 11.25 mL/hr rounded to the tenths place is 11.3 mL/hr..
