Question 1 of 5.
A client who has a history of mitral valve prolapse tells the nurse that she is scheduled to get her teeth cleaned. Which of the following replies by the nurse is most appropriate?
A. The physician will need to reevaluate the status of your heart condition before your dental appointment.'
B. The nurse to remind your dentist that you have a heart condition.'
C. It is important for you to care for your teeth because your heart condition makes you more susceptible to developing oral infections.'
D. We will prescribe a prophylactic antibiotic for you to take before getting your teeth cleaned.'
Explanation: Clients with mitral valve prolapse may require prophylactic antibiotics before dental procedures to prevent infective endocarditis, depending on current guidelines. This is the most appropriate response as it directly addresses the need for preventive measures. The other options either lack specificity or do not address the immediate clinical concern.
Question 2 of 5.
When administering a thrombolytic drug to the client experiencing a myocardial infarction (MI), the nurse explains that the purpose of the drug is to:
A. Help keep him well hydrated.

A. Control chest pain.
B. Reduce coronary artery vasospasm.
