Theory of Health Behavior Change Questions
Question 1 of 5
The nurse is aware that one of the following classes of medications maximizes cardiac performance in clients with heart failure by increasing ventricular contractility?
Correct Answer: D
Rationale: Step-by-step rationale: 1. Inotropic agents directly increase the force of cardiac muscle contraction, leading to improved ventricular contractility in heart failure. 2. Beta-adrenergic blockers reduce the heart rate and contractility, opposite of the desired effect. 3. Calcium channel blockers primarily affect vascular smooth muscle and do not directly enhance cardiac contractility. 4. Diuretics help reduce fluid overload in heart failure but do not directly impact ventricular contractility. Summary: A: Beta-adrenergic blockers decrease contractility. B: Calcium channel blockers do not enhance contractility. C: Diuretics help with fluid overload but do not improve contractility. D: Inotropic agents directly increase ventricular contractility, making them the correct choice.
Question 2 of 5
Jomari is diagnosed with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is stabilized and prepared for discharge. When preparing the client for discharge and home management, which of the following statements indicates that the client understands her condition and how to control it?
Correct Answer: A
Rationale: The correct answer is A because it demonstrates a clear understanding of the importance of hydration and monitoring symptoms in managing HHNS. By recognizing the signs of dehydration and the need to drink more fluids, the client can prevent complications. Choice B is incorrect because consuming soda with sugar can worsen the condition by raising blood glucose levels. Choice C is incorrect as it focuses solely on monitoring blood glucose levels without addressing the crucial aspect of hydration. Choice D is incorrect because eating a snack high in carbohydrates can exacerbate hyperglycemia, leading to further complications.
Question 3 of 5
For a client with Graves' disease, which nursing intervention promotes comfort?
Correct Answer: D
Rationale: The correct answer is D: Maintaining room temperature in the low-normal range. For a client with Graves' disease, they may experience heat intolerance due to increased metabolism. Maintaining a cooler room temperature can help alleviate discomfort. Choice A is incorrect as restricting oral fluids can lead to dehydration, worsening symptoms. Choice B is incorrect as adding extra blankets can increase heat retention, exacerbating discomfort. Choice C is incorrect as limiting high-carbohydrate foods is not directly related to promoting comfort in Graves' disease.
Question 4 of 5
Aldo with a massive pulmonary embolism will have an arterial blood gas analysis performed to determine the extent of hypoxia. The acid-base disorder that may be present is?
Correct Answer: D
Rationale: The correct answer is D: Respiratory alkalosis. In massive pulmonary embolism, there is decreased oxygen exchange in the lungs leading to hypoxia. This causes hyperventilation, leading to a decrease in carbon dioxide levels in the blood, resulting in respiratory alkalosis. Metabolic acidosis (A) and alkalosis (B) are not directly related to pulmonary embolism. Respiratory acidosis (C) would result from hypoventilation, which is not typically seen in pulmonary embolism.
Question 5 of 5
Nurse Patricia is aware that the average length of time from human immunodeficiency virus (HIV) infection to the development of acquired immunodeficiency syndrome (AIDS)?
Correct Answer: D
Rationale: The correct answer is D because, on average, it takes more than 10 years for HIV infection to progress to AIDS without treatment. The latency period can vary, but with advancements in treatment, people can live longer without developing AIDS. Choice A is incorrect because 5 years is too short for HIV to progress to AIDS on average. Choice B is also incorrect as it falls within the same timeframe as choice A. Choice C is incorrect as although 10 years is closer to the average, it is still not long enough for the majority of individuals.
