2. Client is alert, oriented X3, and blood pressure is 120/60, with no other complaints.
3. Client's heart rate is 50 and blood pressure is 110/62, with no other complaints.
4. Client's respiratory rate is 16, blood pressure is 114/70, and client is pain-free.
Client is lightheaded and complaining of chest discomfort.
Rationale: Sinus bradycardia requires treatment when the client is exhibiting a decrease in cardiac output manifesting itself in complaints of angina, syncope, dizziness, shortness of breath, weakness, and possible changes in mental status. As a result of decreased cardiac output, the client may manifest hypotension. The other answer choices do not present a need for treatment.
