The nurse identifies that the goal of decreasing the cardiac workload for a client receiving atenolol 25 mg PO BID for unstable angina is met when the client has:
An increase in urine output.
Less dyspnea with activity.
A blood pressure of 120/80 mmHg.
A heart rate of 65 per minute.
The Correct Answer is D
Choice a reason:
An increase in urine output can be a sign of improved kidney function or the effect of medications, but it is not a direct indicator of reduced cardiac workload. Atenolol, a beta-blocker, primarily reduces the heart rate and myocardial oxygen demand, not urine output.
Choice b reason:
Less dyspnea with activity suggests improved cardiovascular efficiency, but it is not a specific measure of cardiac workload. Dyspnea can be influenced by respiratory conditions and is not solely determined by cardiac function.
Choice c reason:
A blood pressure of 120/80 mmHg is considered optimal for most adults and indicates good control of hypertension. However, it does not specifically reflect the cardiac workload, which is more directly affected by heart rate and myocardial oxygen demand.
Choice d reason:
A heart rate of 65 per minute is a clear indicator that atenolol is effective in reducing cardiac workload. Atenolol decreases the heart rate, which in turn reduces myocardial oxygen demand and the overall workload on the heart. This is particularly important for patients with unstable angina, where reducing the heart's workload can prevent angina attacks and potential myocardial infarction.

Correct Answer is D
Explanation
Choice A Reason
A client with paranoid personality disorder is typically not described as superficially charming. This description is more often associated with other personality disorders, such as antisocial personality disorder, where individuals may use charm to manipulate others for personal gain.
Choice B Reason
Being friendly and open is generally not characteristic of paranoid personality disorder. Individuals with this disorder are often wary of others and may be perceived as cold or distant due to their mistrust.
Choice C Reason
While intensity and impulsivity can be seen in various personality disorders, they are not the defining features of paranoid personality disorder. These traits are more commonly associated with borderline personality disorder.
Choice D Reason
Guarded and suspicious are hallmark descriptors for someone with paranoid personality disorder. Individuals with this condition are often very distrustful of others, suspecting that others have ulterior motives or are out to harm them. They may be preoccupied with doubts about the loyalty or trustworthiness of friends or associates.
Correct Answer is B
Explanation
Choice a reason:
Diuretic use is not typically associated with an increased risk of developing fibromyalgia. Diuretics are commonly used to treat conditions like hypertension and edema by helping the body eliminate excess fluid, but they do not contribute to the onset of fibromyalgia¹.
Choice b reason:
Emotional or physical trauma has been identified as a risk factor for fibromyalgia. Individuals who experience significant stress or traumatic events may develop the disorder due to changes in how their central nervous system processes pain. Stress can lead to long-lasting effects on the body and may trigger fibromyalgia or worsen its symptoms²³⁴.
Choice c reason:
Being overweight is not a direct risk factor for fibromyalgia, but it can exacerbate symptoms in those who have the condition. Excess weight can increase the strain on the body and may contribute to the chronic pain and fatigue associated with fibromyalgia. However, it is not considered a causative factor¹.
Choice d reason:
Being an adolescent male is not a recognized risk factor for fibromyalgia. The disorder is more commonly diagnosed in women, and while it can occur at any age, it is most often diagnosed during middle age. Gender and age alone are not sufficient to determine the risk of developing fibromyalgia.
