The nurse is evaluating the medical prescription of carvedilol 6.25 mg PO daily for a client with a history of unstable angina. Which of the following reflects that the medication's action has been effective?

Urine output 50 mL per hour

Heart rate 60 beats/minute

Heart rhythm regular

Blood pressure 120/90

Answer and Explanation

The Correct Answer is B

A. While it may have some impact on kidney function indirectly through its effects on blood pressure and heart function, urine output is not the primary parameter used to assess the effectiveness of carvedilol in a patient with a history of unstable angina.
B. Carvedilol, as a beta-blocker, helps reduce heart rate by blocking the effects of adrenaline on the heart. In unstable angina, lowering the heart rate can reduce myocardial oxygen demand, which is beneficial in managing ischemic symptoms
C. Carvedilol primarily affects heart rate and blood pressure but doesn't directly regulate heart rhythm. However, in patients with certain cardiac conditions, like heart failure or left ventricular dysfunction after a heart attack, carvedilol can sometimes help to stabilize heart rhythm indirectly by reducing stress on the heart.
D. Carvedilol is also effective in reducing blood pressure, which is beneficial in patients with unstable angina, as it decreases the workload on the heart and the oxygen demand of the myocardium. A blood pressure reading of 120/90 is within the normal range for an adult and indicates good control of blood pressure.

Correct Answer is B

Explanation

B. It is essential to complete the full course of antibiotics as prescribed by the healthcare provider, even if symptoms improve before the course is finished. This ensures that all bacteria causing the infection are eradicated, reducing the risk of recurrence and development of antibiotic resistance.
A. Antibiotics should be taken exactly as prescribed and for the full duration of the treatment course. Incomplete or inconsistent use of antibiotics can lead to incomplete eradication of the infection, development of antibiotic resistance, and recurrence of the infection.
C. While cranberry juice is often recommended for urinary tract health due to its ability to prevent bacterial adherence to the bladder wall, it is not a substitute for antibiotics in treating urinary tract infections.
D. Typically, urine cultures are reserved for cases where the diagnosis is uncertain, or the infection is recurrent or complicated. In uncomplicated UTIs, empirical antibiotic treatment based on symptoms and clinical presentation is usually sufficient.

A. "Alpha adrenergic blockers can be used to help control my symptoms." B. "I realize that this growth will become cancerous over time." C. "As my condition progresses, I may need to consider surgical management." D. "There are several nonsurgical treatment options available."

Correct Answer is B

Explanation

A. Alpha adrenergic blockers are medications commonly used to help control symptoms of benign prostatic hyperplasia (BPH) by relaxing the muscles of the prostate and bladder neck, thereby improving urine flow and reducing urinary symptoms such as hesitancy, urgency, and frequency.
B. Benign prostatic hyperplasia (BPH) is not cancerous and does not typically progress to prostate cancer. While both BPH and prostate cancer involve growth of the prostate gland, they are distinct conditions with different risk factors, symptoms, and treatment approaches.
C. In some cases, if symptoms of BPH are severe or do not respond to medication, surgical management may be necessary. Common surgical procedures for BPH include transurethral resection of the prostate (TURP) or laser prostatectomy.
D. There are several nonsurgical treatment options available for BPH, including alpha adrenergic blockers, 5-alpha reductase inhibitors, combination therapy, and minimally invasive procedures such as transurethral microwave thermotherapy (TUMT) or prostatic artery embolization (PAE).
