Explanation:
Ventricular fibrillation (VF) is a dysrhythmia that can be lethal and should be treated immediately
with cardiopulmonary resuscitation (CPR) and defibrillation. It is characterized by irregular
waveforms of varying shapes and amplitude on the electrocardiogram (ECG). Mechanically, there is
no effective contraction, cardiac output, or pulse.
(Option 1) Atrial fibrillation (AF) is an abnormal heart rhythm, but the client usually has a pulse. In
addition, AF is not as concerning as VF.
(Option 2) Premature ventricular contractions (PVCs) can indicate ventricular irritability, but the client
has a pulse.
(Option 4) Ventricular tachycardia (VT) is a dysrhythmia that can be lethal. A client with VT is
prioritized after a client with VF as it is possible to have a pulse in VT.
Educational objective:
VF is a dysrhythmia that can be lethal. The client does not have a pulse and must be treated
immediately with CPR and defibrillation.
2-The clinic nurse is caring for an elderly client who is overweight and being treated for
hypertension. What is most important for the nurse to emphasize to prevent a stroke (acute brain
attack)?
1. Consume a low-fat, low-salt diet
2. Do not smoke cigarettes
3. Exercise and lose weight
4. Take prescribed antihypertensive medications
Explanation:
Risk factors for stroke include diabetes, high cholesterol, hypertension, smoking, obesity (particularly
in the abdomen), older age, and genetic susceptibility. The single most important modifiable risk
factor ishypertension. Stroke risk can be reduced up to 50% with appropriate treatment of
hypertension. Because clients often experience side effects from the antihypertensive medications
and don't feel bad with untreated hypertension, they may not realize that it is essential to continue the
medications. The nurse should therefore emphasize this point.
(Option 1) A low-fat, low-salt diet is beneficial to the client, but managing hypertension with
medications is most important.
