Evolve HESI Medical Surgical Practice Exam Quizlet

Correct Answer: A

Rationale: The correct answer is A: Decreased chest pain. Nitroglycerin is a vasodilator that works by decreasing myocardial oxygen consumption, which helps to reduce chest pain caused by angina. Therefore, a reduction in chest pain is a positive indicator of the drug's effectiveness. Choices B, C, and D are incorrect because nitroglycerin does not typically increase blood pressure or heart rate; instead, it often causes a decrease in blood pressure due to vasodilation and may cause a reflex tachycardia (increased heart rate) as a compensatory response to lowered blood pressure.

Correct Answer: C

Rationale: Increasing the daily intake of oral fluids is crucial for clients with asthma and bronchitis as it helps to liquefy thickened mucus, making it easier to clear the airways and manage symptoms. This self-care measure can improve the client's ability to breathe more effectively. Choice A is not the most immediate concern when addressing thickened mucus and breathing difficulties. While avoiding crowded areas is beneficial to prevent respiratory infections, it is not directly related to managing thickened secretions. Teaching anxiety reduction methods is important for overall well-being, but it does not directly address the physiological issue of thickened mucus in the airways.

Correct Answer: C

Rationale: The correct answer is C: Hyperkalemia. Sodium polystyrene sulfonate (Kayexalate) is used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the large intestine, which is then eliminated through the feces. Therefore, the nurse should monitor the client for changes in potassium levels to ensure the effectiveness of the treatment. Choices A, B, and D are incorrect because sodium polystyrene sulfonate (Kayexalate) is not associated with causing hyponatremia, hypokalemia, or hypocalcemia.

Correct Answer: B

Rationale: The primary purpose of administering anticoagulants to a patient with atrial fibrillation is to prevent clot formation. Patients with atrial fibrillation are at an increased risk of forming blood clots in the heart, which can lead to stroke if they travel to the brain. Anticoagulants help to reduce this risk by inhibiting the clotting process. Therefore, choices A, C, and D are incorrect because anticoagulants do not primarily aim to reduce blood pressure, prevent arrhythmias, or reduce inflammation in patients with atrial fibrillation.

Correct Answer: C

Rationale: The correct dose would be 32 units, which is the sum of 10 units of regular insulin and 22 units of NPH. It is essential to combine the doses of both types of insulin to ensure the client administers the correct total dose. Choices A and B represent the individual doses of regular and NPH insulin, respectively, not the combined total. Choice D is incorrect as it does not reflect the sum of both insulin doses.
