A nurse is caring for a client who has a new diagnosis of atrial fibrillation. Despite medication therapy aimed at correcting the dysrhythmia, the patient has consistently remained in atrial fibrillation for several days. Which of the following interventions would the nurse expect to be ordered for this client?

A. Headache is a common side effect of nitroglycerin due to its vasodilatory effects, especially in the head. Most headaches associated with nitroglycerin are mild and transient. Patients are generally advised to continue using the medication as prescribed unless the headache is severe or persistent.
B. Nitroglycerin tablets are used for the immediate relief of angina symptoms. If the first tablet does not adequately relieve chest pain within 5 minutes, the patient can take a second tablet. If the pain persists after the second tablet, emergency medical attention should be sought. However, it's important to note that the maximum number of tablets that can be taken within a short period should be specified by the healthcare provider, typically 2 or 3 tablets in 15 to 30 minutes.
C. Nitroglycerin can cause orthostatic hypotension, which is a drop in blood pressure upon standing up. This can lead to dizziness or fainting. Therefore, patients should be advised to stand up slowly after taking nitroglycerin to minimize the risk of falls or injury.
D. Nitroglycerin tablets are sensitive to light, heat, and moisture, which can reduce their effectiveness over time. Therefore, it's recommended to replace nitroglycerin tablets every 3 to 6 months to ensure potency and effectiveness.

A. This symptom is consistent with orthopnea, which is common in left-sided heart failure rather than right-sided heart failure. In orthopnea, patients experience shortness of breath when lying flat because fluid accumulates in the lungs due to impaired left ventricular function.
B. Pink-tinged or blood-tinged sputum, known as hemoptysis, can occur in left-sided heart failure due to pulmonary congestion and elevated pressures in the pulmonary circulation. This symptom is not typically associated with right-sided heart failure.
C. This finding suggests pulmonary congestion, which is more indicative of left-sided heart failure. In left- sided heart failure, fluid backs up into the lungs, leading to crackles or rales on auscultation.
D. This statement is consistent with right-sided heart failure. In right-sided heart failure, the right ventricle fails to effectively pump blood into the pulmonary circulation, causing fluid to back up into the venous system. This can lead to peripheral edema (such as in the legs and abdomen) and abdominal distension due to ascites (fluid accumulation in the peritoneal cavity).
