While changing a client's postoperative dressing, the nurse observes purulent drainage at the site.
Before reporting this finding to the healthcare provider, the nurse should note which of the client's laboratory values?

Choice A rationale:

"Phobias are characterized by persistent and irrational fear" (Choice A) is an accurate statement. Phobias are defined by the presence of an intense and irrational fear of a specific object or situation. This fear is persistent and often leads to avoidance behaviors, which can significantly impact the individual's daily life.

Choice B rationale:

"Phobias can be caused by biological factors only" (Choice B) is an inaccurate statement. Phobias can have various causes, including both biological and psychological factors. While there may be genetic predispositions to certain phobias, psychological factors, such as traumatic experiences or learned behaviors, can also contribute to the development of phobias.

Choice C rationale:

"Phobias can be diagnosed based on physical symptoms" (Choice C) is an inaccurate statement. Phobias are typically diagnosed based on the individual's reported symptoms, such as intense fear and avoidance behaviors. There are no specific physical symptoms that directly indicate the presence of a phobia.

Choice D rationale:

"Phobias can be managed with medication alone" (Choice D) is an inaccurate statement. Medication alone is not considered the primary treatment for phobias. While medications like selective serotonin reuptake inhibitors (SSRIs) or benzodiazepines may be prescribed to alleviate anxiety symptoms, the most effective treatment for phobias is psychotherapy, particularly exposure therapy or cognitive-behavioral therapy. These therapies address the root causes of the phobia and help individuals learn to manage their fear.

Choice A rationale:

The client's statement, "I should avoid foods that are high in vitamin K," indicates an understanding of the medication. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-containing foods helps maintain a stable INR (International Normalized Ratio) and warfarin's effectiveness. Clients on warfarin should be educated about avoiding drastic changes in their vitamin K intake.

Choice B rationale:

Taking warfarin with food or on an empty stomach doesn't significantly impact its efficacy. Therefore, this statement is not indicative of the client's understanding of the medication.

Choice C rationale:

The statement "I should report any unusual bleeding or bruising to my provider" is important but doesn't specifically reflect an understanding of warfarin. It's a general caution for anyone taking anticoagulants.

Choice D rationale:

While it's important to avoid excessive use of medications like aspirin that can increase the risk of bleeding, this statement doesn't directly demonstrate an understanding of warfarin itself.
