What response is appropriate when a client with hypertension declines to take prescribed antihypertensive medications because du

aksik [14]

Answer:

The appropriate response should be of informing the client that due to absence of symptoms hypertension is known as 'the silent killer'. The client declines to take the medications but he do not know that how dangerous this disease is. Due to lack of symptoms, many of the people are not aware that they have this disease, and it develops slowly with time and can't be cured but can be controlled by diet and medications. High blood pressure could result in chronic heart diseases and even stroke, renal and arterial diseases too. So, its better to take medication to manage your body's internal conditions.

In ventricular fibrillation, the ventricles twitch randomly instead of beating. This condition causes death within minutes if no

Lana71 [14]

Answer:

Ventricular fibrillation a type of arrhythmia characterized by a very fast heart rate which causes no blood to reach vital organs causing cardiac arrest.While Atrial fibrillation is an atrial tachyarrhythmia characterized by the fact that the atria beat in an uncoordinated way at a very high rate that exceeds 350 beats per minute. As a result, the atria are no longer effective in pumping blood to the ventricles.

Explanation:

Under normal conditions the heart contracts rhythmically and synchronously. This contraction is the result of an electrical impulse that is generated in the atrium, reaches the ventricle and results in a heartbeat. In an arrhythmia there is an alteration of this mechanism that leads to the heart not contracting regularly, generating a rhythm disorder. The contraction of the ventricles pumps blood to the rest of the body. In ventricular fibrillation, the heart rhythm is very fast and chaotic (up to 300 beats per minute) and is characterized by not being able to provoke an efficient heart beat. Thus, the lack of contraction of the ventricles causes the blood to barely be pumped from the heart, producing a collapse of the cardiovascular system and cardiac arrest. Atrial fibrillation is characterized by disorganized and very rapid atrial activity (350-600 beats / min). This leads to an irregular ventricular response (150-200 beats / min) and an irregular pulse.During atrial fibrillation, the atrial contraction that helps fill the ventricles with blood is lost; this can significantly reduce cardiac output, particularly in patients with mitral stenosis, hypertension, or hypertrophic cardiomyopathy.It is associated with an increased risk of thromboembolism (formation of blood clots in the heart that can dislodge and go through the bloodstream until impacted on the a blood vessel, causing lack of irrigation in that area) and therefore stroke (cerebral thromboembolic accident).

A middle-aged client presents to the ed reporting severe chest discomfort. which finding is most indicative of a possible myocar

Sonbull [250]

The correct answer for this question is

chest discomfort not relieved by rest or nitroglycerine.

A medical emergency is a heart attack. A blood clot generally causes a heart attack when it prevents blood from reaching the heart. Tissue loses oxygen and perishes without blood.

The chest, neck, back, or arms may feel tight or painful. Fatigue, dizziness, an irregular heartbeat, and anxiety may also be present. Compared to males, women are more prone to experience unusual symptoms.

The many forms of treatment include prescription drugs, stents, cardiac rehabilitation, and bypass surgery.

When the heart muscle's supply of oxygen is inadequate in one or more places, a heart attack (myocardial infarction) result. When the heart muscle's blood supply is restricted, this occurs.
