A nurse working in an emergency department is assessing a client who is experiencing chest pain that began 6 hr ago. Which of the following findings indicates that the client is having a myocardial Infarction?

Decreased creatine kinase-MB

Decrease in respiratory rate

ST segment depression

Increased troponin I

Answer and Explanation

The Correct Answer is D

Rationale:

A. Decreased creatine kinase-MB: CK-MB is a cardiac enzyme that rises within 4–6 hours of myocardial infarction and peaks around 24 hours. A decrease in CK-MB would not indicate acute myocardial injury and is not a diagnostic marker in this case.

B. Decrease in respiratory rate: A lower respiratory rate is not a typical or reliable indicator of myocardial infarction. Clients experiencing an MI are more likely to show signs of dyspnea, anxiety, or increased respiratory effort due to pain or decreased oxygenation.

C. ST segment depression: ST segment depression may indicate myocardial ischemia or a non-ST elevation myocardial infarction (NSTEMI), but it is less specific than biomarkers like troponin. It may also appear in other conditions such as angina or electrolyte imbalances.

D. Increased troponin I: Troponin I is a highly specific and sensitive cardiac biomarker that rises within 3–6 hours of myocardial injury. An elevated troponin I level 6 hours after the onset of chest pain strongly supports the diagnosis of myocardial infarction.

Correct Answer is B

Explanation

Rationale:

A. Expresses pain freely and loudly: Many Chinese American clients may view overt pain expression as a loss of control or dignity. Cultural norms often encourage stoicism, and clients may underreport pain unless directly asked in a sensitive and respectful manner.

B. Prefers foods that maintain a balance of hot and cold within the body: Traditional Chinese medicine emphasizes balance, particularly of hot and cold elements, especially during the postpartum period. Clients may prefer warm foods and drinks to restore balance and promote healing after childbirth.

C. Prefers to make direct eye contact with health care personnel: In Chinese cultural contexts, direct eye contact can be considered disrespectful or confrontational, especially toward authority figures. Avoiding eye contact may be a sign of respect rather than disinterest.

D. Tends to be very expressive with gestures and body language: Chinese American clients may communicate in a more reserved and controlled manner, often minimizing the use of expressive gestures. Nonverbal communication may be subtle, requiring attentive observation.

A. "We should expect the swelling and tingling to worsen before it gets better." B. "It is important that our child avoids placing anything inside the cast." C. "We should prop the casted arm on pillows for the next 24 hours." D. "We should notify the provider if the cast becomes loose over time. E. "We need to be very careful about how we handle the cast for the first 2 days while it dries."

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"A"},"E":{"answers":"A"}}

Explanation

Rationale:

"We should expect the swelling and tingling to worsen before it gets better." This statement needs reinforcement because worsening swelling and tingling can indicate early signs of compartment syndrome. These symptoms are not normal and should prompt immediate medical attention.

"It is important that our child avoids placing anything inside the cast." This statement reflects understanding because inserting objects inside the cast can break the skin and introduce bacteria, leading to infection. It may also damage the padding and compromise skin protection.
"We should prop the casted arm on pillows for the next 24 hours." Elevating the limb helps reduce swelling and pain by improving venous return. Keeping the casted arm elevated is a standard part of cast care teaching after an injury.
"We should notify the provider if the cast becomes loose over time." A loose cast may no longer immobilize the fracture effectively and can allow excessive movement. It may also rub the skin, increasing the risk of irritation or breakdown.
"We need to be very careful about how we handle the cast for the first 2 days while it dries." This shows understanding because a plaster cast takes 24 to 48 hours to fully dry. Improper handling can cause pressure indentations, leading to skin damage and poor cast integrity.
