A client is diagnosed with atrial fibrillation and has experienced a transient ischemic attack (TI

A diuretic medication

An oral anticoagulant medication

A beta blocker medication

An antihyperuricemic medication

Answer and Explanation

The Correct Answer is B

Choice A reason:

A diuretic medication is generally used to remove excess fluid from the body and treat conditions such as hypertension and heart failure. While it can be part of the management plan for atrial fibrillation if there is fluid overload, it is not specifically used to prevent thromboembolic events like TIA, which are a major concern in atrial fibrillation patients.

Choice B reason:

An oral anticoagulant medication is the most appropriate choice for a patient with atrial fibrillation who has experienced a TIA. Anticoagulants, such as warfarin or newer direct oral anticoagulants (DOACs), are used to prevent blood clots from forming and reduce the risk of stroke and other thromboembolic events. This choice directly addresses the primary goal of reducing the risk of future TIAs or strokes in patients with atrial fibrillation.

Choice C reason:

A beta blocker medication can be useful in managing atrial fibrillation by controlling the heart rate and reducing the risk of symptomatic episodes. However, beta blockers do not address the risk of thromboembolism, which is critical in the context of a patient with a history of TIA. Thus, while beneficial for rate control, they do not serve the primary purpose of preventing strokes in this scenario.

Choice D reason:

An antihyperuricemic medication is used to lower uric acid levels and treat conditions like gout. It is not relevant to the management of atrial fibrillation or the prevention of thromboembolic events. Including this option does not align with the clinical needs of a patient with atrial fibrillation and a history of TIA.

Correct Answer is C

Explanation

Choice A reason:

Oxymetazoline is not used for maintenance treatment of heart failure. It is a topical decongestant used to relieve nasal congestion and is not indicated for cardiac conditions.

Choice B reason:

Oxymetazoline provides rapid relief of nasal congestion and does not take weeks to show effects. Its action is almost immediate, making it effective for short-term use.

Choice C reason:

Limiting the use of oxymetazoline to 3 days is crucial to prevent rebound nasal congestion, a condition where the nasal passages become more congested once the medication is stopped. Overuse can lead to dependency and worsening congestion.

Choice D reason:

Oxymetazoline does not typically cause drowsiness, so taking it at bedtime is not necessary. This statement does not apply to the pharmacological effects of this medication.

A. dantrolene B. neostigmine C. vecuronium D. naloxone

Correct Answer is A

Explanation

Choice A reason: This is the correct answer. Dantrolene is the medication of choice for treating malignant hyperthermia, which is indicated by muscle rigidity and a rapid rise in body temperature. It works by reducing calcium release in muscles, thereby alleviating the symptoms.

Choice B reason: Neostigmine is an acetylcholinesterase inhibitor used to treat myasthenia gravis and to reverse the effects of certain muscle relaxants post-surgery. It is not indicated for the treatment of malignant hyperthermia.

Choice C reason: Vecuronium is a muscle relaxant used during anesthesia to induce muscle relaxation. It is not a treatment for malignant hyperthermia and does not address the symptoms of muscle rigidity and hyperthermia.

Choice D reason: Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. It has no role in the treatment of malignant hyperthermia and is therefore not relevant to this scenario.
