The nurse is caring for client who is diagnosed with hypertrophic cardiomyopathy. Which medical Intervention should the nurse anticipate for this client for the complications of dysrhythmias?

Insertion of a cardioverter-defibrillator

A medication regimen that includes nitrates

Immediate cardiac transplantation

Insertion of a drug eluting stent

Answer and Explanation

The Correct Answer is A

A) Insertion of a cardioverter-defibrillator:
Hypertrophic cardiomyopathy (HCM) is a condition characterized by abnormal thickening of the heart muscle, particularly the septum, which can lead to obstruction of blood flow and contribute to the development of arrhythmias. The most concerning arrhythmias in HCM include ventricular tachycardia and ventricular fibrillation, both of which can lead to sudden cardiac arrest. A cardioverter-defibrillator (ICD) is a device that monitors the heart's rhythm and can deliver a shock to restore normal rhythm in the event of a life-threatening arrhythmia.

B) A medication regimen that includes nitrates:
Nitrates are vasodilators commonly used in the treatment of conditions like angina and heart failure. However, nitrates are generally avoided in patients with hypertrophic cardiomyopathy because they can exacerbate the condition by decreasing preload and increasing the outflow tract obstruction due to the thickened heart muscle.

C) Immediate cardiac transplantation:
Cardiac transplantation is a treatment for end-stage heart failure, typically in patients who have not responded to medical or surgical treatments. While hypertrophic cardiomyopathy can lead to heart failure, it is not the first line treatment for dysrhythmias or complications from the disease.

D) Insertion of a drug-eluting stent:
Drug-eluting stents are used to prevent restenosis (narrowing) of coronary arteries after percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD). However, hypertrophic cardiomyopathy is not caused by coronary artery disease.

Correct Answer is A

Explanation

A) Prepare for a STAT computed tomography (CT) scan:
A severe headache in a client with a suspected stroke could be indicative of increased intracranial pressure (ICP), a hemorrhagic stroke, or another serious complication like cerebral edema. The priority intervention is to perform a CT scan to determine whether the stroke is ischemic (caused by a blockage) or hemorrhagic (caused by bleeding). This is crucial because the treatment approach for these two types of strokes differs significantly. For example, hemorrhagic strokes require immediate management to control bleeding and reduce ICP, whereas ischemic strokes may be treated with thrombolytics or other interventions. Therefore, preparing for a CT scan is the most urgent action to accurately diagnose the type of stroke and guide treatment decisions.

B) Obtain a 12-lead electrocardiogram (ECG):
While an ECG may be useful in assessing the cardiac rhythm and identifying potential arrhythmias (which can contribute to stroke risk), it is not the priority intervention in a patient with a suspected stroke and severe headache. The primary concern is to identify the type of stroke (ischemic or hemorrhagic), and a CT scan is the most direct way to do this. A 12-lead ECG can be obtained later if cardiac issues are suspected after stroke diagnosis.

C) Start an intravenous infusion of D5W at 100 mL/hr:
Starting an IV infusion of D5W (5% dextrose in water) is not an appropriate priority for a patient with a severe headache and suspected stroke. In fact, administering dextrose solutions may worsen the patient's condition in the case of a hemorrhagic stroke, as it could exacerbate cerebral edema or increase intracranial pressure. Fluid management in stroke patients should be approached cautiously, and IV fluids should be tailored to the patient's specific needs. The focus should be on imaging to determine the type of stroke before initiating interventions like IV fluids.

D) Administer a nonnarcotic analgesic:
While pain relief is important, administering a nonnarcotic analgesic (such as acetaminophen or ibuprofen) is not the priority in this situation. The patient's severe headache could be a sign of a serious complication like increased ICP or hemorrhagic stroke, which requires immediate diagnostic workup, not just pain management. Administering pain medication without understanding the underlying cause of the headache could mask symptoms and delay critical treatment.

A. Clubbing of the fingers B. A heart murmur C. Barrel chest D. Bradycardia

Correct Answer is B

Explanation

A) Clubbing of the fingers
Clubbing of the fingers is typically associated with chronic hypoxia, often due to conditions like chronic obstructive pulmonary disease (COPD), congenital heart defects, or chronic respiratory disorders. While mitral valve stenosis can lead to pulmonary congestion and sometimes hypoxia, clubbing is not a hallmark finding of mitral valve stenosis.

B) A heart murmur
Mitral valve stenosis is commonly characterized by a heart murmur. The stenosis (narrowing) of the mitral valve obstructs blood flow from the left atrium to the left ventricle, leading to turbulent blood flow. This creates a characteristic diastolic murmur (a low-pitched, rumbling murmur heard best at the apex of the heart with the patient in the left lateral decubitus position).

C) Barrel chest
A barrel chest is more commonly associated with chronic obstructive pulmonary disease (COPD), emphysema, and other conditions that cause long-term hyperinflation of the lungs. It is not a typical finding in mitral valve stenosis. The shape of the chest may change over time in patients with severe left-sided heart failure, but this is not a primary or direct consequence of mitral valve stenosis.

D) Bradycardia
Bradycardia (a slow heart rate) is not a characteristic finding of mitral valve stenosis. In fact, mitral valve stenosis can lead to increased heart rates due to reduced cardiac output and compensatory mechanisms. As the left atrium becomes increasingly distended from the obstruction, atrial fibrillation (a rapid, irregular heartbeat) is common in mitral valve stenosis.
