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
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 A
Explanation
A. Cleans and dries the perianal area after each diarrheal stool: This is the correct option. Effective perianal care for a client with diarrhea, such as ulcerative colitis, involves gentle cleansing and thorough drying of the perianal area after each stool. Proper hygiene helps prevent skin breakdown and irritation caused by prolonged contact with stool.
B. Alcohol can be irritating to the skin and may exacerbate perianal irritation and discomfort. Therefore, using alcohol compresses is not considered an appropriate perianal care practice.
C. While antidiarrheal medications may be prescribed for clients with ulcerative colitis to help manage symptoms, asking for medication after each stool is not a typical or recommended approach. The frequency and timing of antidiarrheal medication administration should be based on healthcare provider recommendations and individual symptom management plans.
D. While Sitz baths can provide relief from perianal discomfort and promote healing, taking an hour-long Sitz bath after each stool may be impractical and excessive. Sitz baths are typically recommended for shorter durations (e.g., 10-20 minutes) and may be used periodically rather than after every stool.
Correct Answer is B
Explanation
B. Obtaining blood and urine specimens for culture and sensitivity is a critical first step. These specimens help identify the causative organism(s) and determine their susceptibility to antibiotics, guiding appropriate antibiotic therapy. Prompt initiation of targeted antibiotic treatment is essential in managing sepsis effectively.
A. This action is important for assessing the presence of any urinary tract stones or debris, which can be helpful in diagnosing the cause of the urinary tract infection. However, it is not the first action the nurse should take in managing a client admitted with sepsis secondary to a urinary tract infection.
C. Administering antibiotics before obtaining appropriate cultures may lead to empirical treatment without knowing the specific pathogen causing the infection. It is important to obtain cultures first to guide antibiotic selection and ensure optimal treatment.
D. Contact precautions may be necessary if the client is found to have a multidrug-resistant organism or if there are specific infection control concerns. However, placing the client on contact precautions is not the first action the nurse should take in managing sepsis secondary to a urinary tract infection.
