The nurse is teaching a group of staff nurses about brain (B-type) natriuretic peptide (BNP). Which statement by the group would indicate that they understand the instruction?
"It is an amino acid which reflects damage to the endothelial lining of arteries.
"It is a substance composed of free fatty acids reflective of atherosclerosis
"It is a reliable indicator of the presence of heart failure."
“It is a protein produced by the liver in response to systemic inflammation."
The Correct Answer is C
A. "It is an amino acid which reflects damage to the endothelial lining of arteries." BNP is not related to endothelial damage.
B. "It is a substance composed of free fatty acids reflective of atherosclerosis." BNP is not composed of free fatty acids, and it does not reflect atherosclerosis.
C. "It is a reliable indicator of the presence of heart failure." BNP is a hormone released by the heart in response to increased pressure and volume. Elevated levels of BNP are commonly used as a diagnostic marker for heart failure, especially during exacerbations or decompensation.
D. "It is a protein produced by the liver in response to systemic inflammation." BNP is produced by the heart, not the liver.

Correct Answer is ["A","B","C","E"]
Explanation
A. Bring the crash cart to the bedside: Essential for advanced cardiac life support (ACLS), including defibrillation and medications.
B. Start cardiopulmonary resuscitation: High-quality CPR is critical to maintain circulation until defibrillation can occur.
C. Defibrillate the client: Defibrillation is the definitive treatment for ventricular fibrillation to restore a normal rhythm.
D. Administer adenosine (Adenocard) to assist in determining the rhythm: Adenosine is used for diagnosing or treating certain supraventricular tachycardias, not ventricular fibrillation.
E. Consider the "Hs and Ts": Identifying reversible causes of cardiac arrest (e.g., hypoxia, hypothermia, toxins) is part of the ACLS protocol.
Correct Answer is C
Explanation
A. It occurs immediately when buttons depressed: The device synchronizes with the R wave and does not deliver the shock immediately.
B. It requires a higher amount of joules than is used in defibrillation: Cardioversion typically requires fewer joules compared to defibrillation.
C. It discharges during ventricular depolarization of the heart: Synchronized cardioversion times the electrical shock with the R wave (ventricular depolarization) to avoid delivering energy during the T wave, which could induce ventricular fibrillation.
D. It is programmed to occur in non-sync mode: Cardioversion must be synchronized; non-sync mode is used in defibrillation.
