ATI Medical Surgical Proctored Exam

Correct Answer: B

Rationale: In acute renal failure, monitoring serum potassium is crucial because impaired kidney function can lead to hyperkalemia, which can result in life-threatening cardiac dysrhythmias. Elevated potassium levels need close monitoring and prompt interventions to prevent serious complications.

Correct Answer: C

Rationale: Assessing for chest pain is crucial in post-MI clients as it can indicate complications such as reinfarction or ischemia.

Correct Answer: A

Rationale: The pain of an MI is often accompanied by shortness of breath and feelings of fear or anxiety. It typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Unlike stable angina, the pain of an MI occurs without a known cause such as exertion.

Correct Answer: C

Rationale: The Joint Commission's Core Measures set for MI includes percutaneous coronary intervention within 90 minutes of the diagnosis of myocardial infarction. Since the client presented at 1500 (3:00 PM), the percutaneous coronary intervention should be performed no later than 1630 (4:30 PM), to adhere to the 90-minute timeline for optimal outcomes.

Correct Answer: C

Rationale: Alpha1-antitrypsin (AAT) deficiency is associated with a higher risk of chronic obstructive pulmonary disease (COPD), especially if the individual smokes. This condition is caused by a recessive gene. Individuals with one allele typically produce enough AAT to prevent COPD unless they smoke. However, those with two alleles are at high risk for COPD even without exposure to smoke or other irritants. Being a carrier of AAT deficiency does not guarantee that one's children will develop the disease; it depends on the AAT levels of the partner. While involving a genetic counselor may be beneficial in the long run, the immediate concern of the client's question should be addressed first.
