A nurse is providing teaching for a client who has a new diagnosis of angina pectoris. Which of the following information should the nurse include about anginal pain?
The pain usually lasts longer than 20 min.
The pain persists with rest and organic nitrates.
Pain can often be relieved by sitting up.
Exertion and anxiety can trigger the pain.
The Correct Answer is D
Choice A Reason: This is incorrect. Anginal pain usually lasts less than 20 min and subsides with rest or medication. Pain that lasts longer than 20 min may indicate a myocardial infarction.
Choice B Reason: This is incorrect. Anginal pain usually responds to rest and organic nitrates, such as nitroglycerin. Pain that does not improve with these measures may indicate unstable angina or a myocardial infarction.
Choice C Reason: This is incorrect. Anginal pain is not affected by the position of the client. Pain that is relieved by sitting up may indicate pericarditis or pleurisy.
Choice D Reason: This is correct. Anginal pain is caused by a temporary imbalance between the oxygen demand and supply of the myocardium. Factors that increase the oxygen demand, such as exertion, anxiety, cold, or heavy meals, can trigger anginal pain.

Correct Answer is C
Explanation
Choice A Reason: This is incorrect because shortening of P-wave duration is not a sign of hyperkalemia or its reversal.
P-wave duration reflects the time it takes for the atria to depolarize and contract.
Choice B Reason: This is incorrect because restoration of QRS complex amplitude is not a sign of hyperkalemia or its reversal. QRS complex amplitude reflects the voltage or strength of the ventricular depolarization and contraction.
Choice C Reason: This is correct because the reduction of T-wave amplitude is a sign of hyperkalemia reversal. T-wave amplitude reflects the repolarization or recovery of the ventricles after contraction. Polystyrene sulfonate is a medication that lowers the serum potassium level by binding to it in the gastrointestinal tract and excreting it in the stool. High serum potassium level, or hyperkalemia, can cause cardiac arrhythmias and ECG changes, such as peaked T waves, prolonged PR interval, flatened P waves, widened QRS complex, and ventricular fibrillation. By lowering the serum potassium level, polystyrene sulfonate can reverse these ECG changes and normalize the cardiac rhythm.
Choice D Reason: This is incorrect because the widening of the QRS complex is a sign of hyperkalemia, not its reversal. Widening of the QRS complex reflects the delay or impairment of ventricular depolarization and contraction.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because dabigatran does not affect the electrical activity of the heart or the conduction system. It does not slow down the ventricular response to the atrial impulses.
Choice B Reason: This is incorrect because dabigatran does not dissolve existing clots in the bloodstream. It only prevents new clots from forming.
Choice C Reason: This is correct because dabigatran reduces the risk of stroke in clients who have atrial fibrillation by preventing clot formation and reducing blood viscosity. Dabigatran is an anticoagulant medication that prevents the formation of blood clots in the heart and blood vessels. Atrial fibrillation is a condition where the atria beat irregularly and rapidly, which can cause blood to pool and clot in the heart chambers. These clots can travel to the brain and cause a stroke. Dabigatran reduces the risk of stroke by preventing clot formation and reducing blood viscosity.
Choice D Reason: This is incorrect because dabigatran does not restore normal sinus rhythm in clients who have atrial fibrillation. It does not affect the heart rate or rhythm.
