The nurse would contact the prescriber for safety concerns about using carvedilol in which of the following clients?

A 60 year old woman with cardiac dysrhythmias post myocardial infarction. Her HR is 39 & irregular, BP 147/65

A 55-year-old woman with HTN due to renal failure from chronic pyleonephritis. HR 92. BP 145/72

A 78-year-old man with a history of hyperlipidemia & cardiac dysfunction. He is in 3rd degree heart block. HR 42. BP 92/65

A 49-year-old male, BMI 36, history of type 2 diabetes & HTN. HR 105, BP 158/92

Answer and Explanation

The Correct Answer is C

A. A 60-year-old woman with cardiac dysrhythmias post myocardial infarction. Her HR is 39 & irregular, BP 147/65: Although her heart rate is low, carvedilol is commonly used post-MI to reduce mortality, especially in patients with dysrhythmias. However, caution is warranted, and dosage adjustments or withholding may be necessary due to bradycardia.

B. A 55-year-old woman with HTN due to renal failure from chronic pyelonephritis. HR 92. BP 145/72: This client has stable vitals, and carvedilol can be safely used to help manage hypertension. Renal impairment requires monitoring, but it is not a contraindication if renal function is closely followed.

C. A 78-year-old man with a history of hyperlipidemia & cardiac dysfunction. He is in 3rd degree heart block. HR 42. BP 92/65: Carvedilol is contraindicated in clients with 2nd or 3rd degree heart block without a functioning pacemaker. It can worsen bradycardia and conduction delays, making its use unsafe in this client without rhythm control support.

D. A 49-year-old male, BMI 36, history of type 2 diabetes & HTN. HR 105, BP 158/92: This client is hypertensive and tachycardic, both of which carvedilol can help manage. Although diabetes requires careful monitoring for hypoglycemia, there is no contraindication in this scenario.

Correct Answer is D

Explanation

A. Maintain the infusion because the client had a cardiac arrest: While epinephrine is essential during cardiac arrest, continuing a high-dose infusion post-resuscitation without reassessment may lead to complications like tachycardia, hypertension, and increased myocardial oxygen demand.

B. Continue to monitor the client's rhythm closely: Ongoing monitoring is important, but it is a passive intervention. The heart rate of 120 bpm may reflect excessive adrenergic stimulation from epinephrine, and further action is needed to prevent deterioration.

C. Suggest that the client's medication be changed to norepinephrine: Norepinephrine is another vasopressor that has less of a beta-1 adrenergic effect compared to epinephrine. It is primarily used for hypotension and septic shock, not as a direct substitute for epinephrine post-cardiac arrest. Changing to another vasopressor without indication is not the best initial step.

D. Ask the physician if the dose can be decreased: A heart rate of 120 bpm may indicate that the epinephrine dose is too high, causing sympathetic overstimulation. Prolonged or excessive tachycardia increases myocardial oxygen demand, which can be detrimental, especially in a post-arrest heart. Decreasing the dose can help prevent arrhythmias or myocardial ischemia, making this the most appropriate and proactive action.

A. Increase in systolic blood pressure 10 mmHg above client's norm B. reports dyspnea after walking up 2 flights of stairs C. Jugular vein distention and +3 peripheral edema D. Complaints of epigastric pain after eating a large meal

Correct Answer is C

Explanation

A. Increase in systolic blood pressure 10 mmHg above client's norm: A mild increase in systolic blood pressure is not a specific indicator of mitral stenosis progression. Blood pressure fluctuations may occur due to various factors and are not typically used as a primary marker of worsening valve disease.

B. reports dyspnea after walking up 2 flights of stairs: Exertional dyspnea is a common early symptom of mitral stenosis due to reduced left atrial emptying and pulmonary congestion. However, this does not necessarily indicate worsening unless the symptom becomes more severe or occurs with minimal exertion.

C. Jugular vein distention and +3 peripheral edema: These are signs of right-sided heart failure, which may result from long-standing mitral stenosis leading to pulmonary hypertension and subsequent right ventricular hypertrophy and failure. This indicates disease progression and worsening cardiac function.

D. Complaints of epigastric pain after eating a large meal: Epigastric discomfort is not a typical symptom of mitral stenosis and is more likely related to gastrointestinal issues. It does not reflect the status or progression of the cardiac condition.
