Atrial fibrillation
Atrial flutter
Premature atrial contractions
Stable angina
The Correct Answer is C
A. Atrial fibrillation is characterized by an irregularly irregular rhythm and absence of distinct P-waves.
B. Atrial flutter typically presents with "saw-tooth" flutter waves rather than extra P-waves.

Correct Answer is A
Explanation
A. This statement indicates a lack of understanding about hidden sodium in restaurant foods. Many restaurant dishes contain high levels of sodium, even if additional salt is not added at the table. The client needs to be educated about choosing low-sodium options when dining out and asking about the sodium content of meals.
B. This statement reflects correct understanding, as fresh vegetables typically contain less sodium than canned vegetables, which often have added salt.
C. This statement shows proper knowledge, as reading nutrition labels helps identify foods with high sodium content, allowing for better dietary choices.
D. This statement is appropriate, as using lemon juice and herbs is a good alternative to adding salt for flavoring food.
Correct Answer is A
Explanation
A. Transporting the patient to the cardiac catheterization lab for percutaneous coronary intervention (PCI) is the priority intervention for a patient with an ST-elevation myocardial infarction (STEMI). PCI is the preferred treatment to restore blood flow to the affected coronary artery.
B. Aggressive diuresis and digoxin are not appropriate for the acute management of a STEMI. Diuresis may be used in cases of heart failure but is not the immediate priority.
C. Synchronized cardioversion and radiofrequency catheter ablation are treatments for certain arrhythmias but are not indicated for the acute management of STEMI.
D. Administering gemfibrozil, a lipid-lowering agent, and preparing for a stress test are not appropriate interventions in the acute setting of a STEMI. Immediate reperfusion therapy is necessary.
