A provider has prescribed quetiapine 50 mg PO, divided equally every 12 hours for 3 days. The available medication is quetiapine 25 mg tablets.

How many tablets should the nurse administer per dose on the third day?

Choice A rationale

Acute laryngotracheobronchitis, also known as croup, is a common childhood condition that is usually caused by a viral infection. The main symptom is a distinctive barking cough. A cool mist tent can help to soothe the inflamed airways and reduce stridor, which is a high-pitched,

wheezing sound caused by disrupted airflow. Therefore, decreased stridor would indicate that the treatment has been effective.

Choice B rationale

While a decreased temperature might indicate a resolution of any underlying infection, it is not directly related to the effectiveness of a cool mist tent in treating acute laryngotracheobronchitis.

Choice C rationale

A barking cough is a symptom of acute laryngotracheobronchitis and does not indicate treatment effectiveness.

Choice D rationale

Improved hydration is important but is not a direct indicator of the effectiveness of the cool mist tent.

Choice A rationale

Vitamin K is not the antidote for heparin. It is used to reverse the effects of warfarin, which is a vitamin K antagonist.

Choice B rationale

Iron is not related to the reversal of heparin. It is a mineral that is crucial for many bodily functions, including the transport of oxygen in the blood.

Choice C rationale

Glucagon is a hormone that raises the level of glucose in the blood. It is not used as an antidote for heparin.

Choice D rationale

Protamine is the correct choice. Protamine sulfate is a drug that reverses the anticoagulant effects of heparin by binding to it and forming a stable complex, thereby neutralizing its anticoagulant activity.
