How is injury manifested on the EKG in a patient experiencing a myocardial infarction?

ST segment elevation

Q wave

inverted T wave

ST segment depression

Answer and Explanation

The Correct Answer is A

A. ST segment elevation: ST segment elevation is a classic sign of myocardial injury, indicating that a portion of the heart muscle is not receiving enough oxygen and is actively injured.

B. Q wave: A Q wave typically appears later, representing a previous myocardial infarction (necrosis), not acute injury.

C. Inverted T wave: This indicates myocardial ischemia, which is a precursor to injury but not indicative of injury itself.

D. ST segment depression: This is typically associated with ischemia or subendocardial infarction, not full-thickness myocardial injury.

Correct Answer is B

Explanation

A. Imbalanced nutrition: Less than body requirements related to decreased oral intake: While this may be relevant, it is not the highest priority in acute appendicitis. Infection prevention is more critical.

B. Risk for infection related to possible rupture of appendix: The primary concern in appendicitis is the risk of rupture, leading to peritonitis and sepsis. This makes infection control the top priority.

C. Chronic pain related to appendicitis: Pain in appendicitis is acute, not chronic. Managing infection risk is more urgent.

D. Constipation related to decreased bowel motility and decreased fluid intake: Constipation is not a priority concern in the context of acute appendicitis. The risk of infection takes precedence.

A. Patient stopped smoking five years prior to hospitalization B. Patient smokes five cigars a week C. Patient uses chewing tobacco D. Patient smoked cigarettes any time during the last year prior to hospitalization

Correct Answer is B

Explanation

A. Patient stopped smoking five years prior to hospitalization: Smoking cessation materials are typically targeted to current smokers or those who have quit very recently (usually within the last year). This patient may not need smoking cessation materials as they have been smoke-free for a significant period.

B. Patient smokes five cigars a week: Smoking cigars still carries health risks similar to cigarettes and indicates the need for smoking cessation materials.

C. Patient uses chewing tobacco: Chewing tobacco is a form of smokeless tobacco, and while harmful, it would require different educational materials focused on smokeless tobacco cessation rather than smoking cessation.

D. Patient smoked cigarettes any time during the last year prior to hospitalization: This indicates current or recent smoking behavior which is a significant risk factor that needs to be addressed.
