A nurse is interpreting the cardiac rhythm strip of a client who was admitted with syncope.
Which of the following images indicates that the client has atrial fibrillation?

A. Varenicline is a medication used for smoking cessation, not for treating gambling disorder.

B. Disulfiram is a medication used to discourage alcohol consumption by inducing unpleasant side effects if alcohol is consumed; it is not used for treating gambling disorder.

C. Sertraline is a selective serotonin reuptake inhibitor (SSRI) antidepressant that has been shown to be effective in treating gambling disorder by reducing gambling urges and behaviors.

D. Clonidine is an alpha-2 adrenergic agonist used to treat conditions such as hypertension and attention deficit hyperactivity disorder (ADHD); it is not typically used for treating gambling disorder.

A. Not all clients with a history of MRSA will require antibiotics. Treatment depends on the presence of active infection, colonization, and other clinical factors.
B. There is no evidence to suggest that individuals can develop immunity to MRSA. MRSA remains a significant pathogen, and individuals with a history of MRSA remain susceptible to reinfection or colonization.
C. A protective environment is not typically required for clients with a history of MRSA. Standard precautions, including hand hygiene and appropriate use of personal protective equipment, are sufficient to prevent transmission.

D. Clients with a history of MRSA can still carry the bacteria on their skin or in their nasal passages and may transmit the infection to others, especially in healthcare settings. Therefore, it is important to adhere to infection control practices to prevent transmission.
