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."

Answer and Explanation

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 B

Explanation

A. Sinus rhythm with first-degree heart block: This rhythm is characterized by a regular sinus rhythm with a prolonged PR interval (greater than 0.20 seconds), indicating a first-degree heart block.

B. ST-segment elevation myocardial infarction (STEMI): STEMI is indicated by significant ST-segment elevation in specific leads, showing acute myocardial infarction.

C. Atrial fibrillation: Atrial fibrillation shows an irregularly irregular rhythm without distinct P waves.

D. Ventricular tachycardia: Ventricular tachycardia is a rapid heart rhythm originating from the ventricles, with wide QRS complexes and no preceding P waves.

A. Compartment syndrome B. Muscle wasting C. Skin breakdown D. Joint Stiffness

Correct Answer is A

Explanation

A. Compartment syndrome. The client’s unrelieved pain, despite analgesics, and the presence of swelling distal to the cast are warning signs of compartment syndrome. This is a medical emergency that occurs when increased pressure within a closed muscle compartment reduces blood flow, leading to tissue damage and pain.

B. Muscle wasting. Muscle wasting typically occurs over time due to disuse and is not a sudden, acute complication like compartment syndrome.

C. Skin breakdown. Skin breakdown could occur from improper cast fitting or prolonged pressure, but it would not cause unrelieved pain in the same way as compartment syndrome.

D. Joint stiffness. Joint stiffness can occur in casted limbs after removal, but it is not an acute complication like compartment syndrome.
