Complete the following sentences by choosing from the list of options. The nurse is planning education for a client prescribed nitroglycerin sublingual tablets. The nurse should instruct the client to dropdown due to the risk for dropdown.
The Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}
• Sit down after taking nitroglycerin: Nitroglycerin causes rapid vasodilation, which can lead to a sudden drop in blood pressure shortly after administration. Sitting or lying down helps reduce the risk of dizziness, syncope, and falls during this period. This instruction is especially important because sublingual nitroglycerin acts quickly.
• Hypotension: Nitroglycerin relaxes vascular smooth muscle, leading to decreased preload and afterload. This vasodilatory effect can cause orthostatic or systemic hypotension, particularly with the first dose. Monitoring and education focus on preventing complications related to low blood pressure, such as lightheadedness or fainting.

Correct Answer is ["B","C","D"]
Explanation
A. Stop taking theophylline if you begin smoking: While smoking significantly increases the metabolism of theophylline (requiring a dose increase to stay effective), the patient should never just stop the medication. Instead, they must notify their provider so the dosage can be adjusted.
B. Theophylline should be taken every day: Theophylline is used for maintenance therapy in conditions like asthma or COPD. Consistent daily dosing helps maintain therapeutic serum levels and prevent exacerbations.
C. Headaches may occur when taking theophylline: Headache is a common side effect due to central nervous system stimulation. Clients should be informed so they can recognize mild, expected reactions versus more serious adverse effects.
D. Report palpitations to your healthcare provider: Theophylline can cause cardiac stimulation, including tachycardia or palpitations. Reporting these symptoms promptly helps prevent serious arrhythmias and allows for dosage adjustment if needed.
E. If you forget your dose, take two the next day: Doubling the dose to make up for a missed one increases the risk of toxicity, including seizures or severe cardiac effects. Clients should take only the next scheduled dose as prescribed.
Correct Answer is C
Explanation
A. Vitamin K: Vitamin K is used to reverse the effects of warfarin by promoting clotting factor synthesis. It is ineffective against dabigatran, a direct thrombin inhibitor, because dabigatran’s mechanism is independent of vitamin K–dependent clotting factors.
B. Activated charcoal: Activated charcoal can reduce the absorption of recently ingested dabigatran if given within a short timeframe after ingestion. However, it is not a specific antidote and is only useful in cases of recent overdose, not for urgent reversal in bleeding emergencies.
C. Idarucizumab: Idarucizumab is a monoclonal antibody fragment that specifically binds to dabigatran, neutralizing its anticoagulant effect. It acts rapidly and is indicated in life-threatening or uncontrolled bleeding or when urgent surgery is required, making it the definitive antidote.
D. Andexanet alfa: Andexanet alfa is an antidote for factor Xa inhibitors such as apixaban and rivaroxaban. It does not reverse dabigatran, which is a direct thrombin inhibitor, and therefore is not appropriate.
