HESI Leadership and Management Quizlet

Correct Answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

Correct Answer: A

Rationale: The correct answer is A: 'Nurses are assistants to physicians.' The public image of nurses, as portrayed by the media, often positions them as assistants to physicians. This perception stems from historical depictions and the traditional hierarchy within healthcare settings. Choice B is incorrect because it reflects how nurses perceive their patients, not how the public views nurses. Choice C is incorrect as nurses are part of the broader healthcare team but are not seen as fundamentally different from other healthcare providers by the public. Choice D is incorrect as while nurses play a crucial role in shaping healthcare, the public perception often focuses more on their supportive role in the healthcare system.

Correct Answer: A

Rationale: The correct answer is A: 'Decreased self-care in activities of daily living related to fatigue.' Patients with fibromyalgia commonly experience fatigue, which can lead to decreased ability to perform self-care activities. This nursing diagnosis addresses a direct consequence of fibromyalgia. Choices B, C, and D are incorrect because they do not directly correlate with the common manifestations of fibromyalgia. Impaired mental functioning related to electrolyte imbalances and increased vigilance secondary to electrolyte imbalances are not typical presentations of fibromyalgia. 'At risk for a swallowing disorder related to fibromyalgia' is not a common nursing diagnosis associated with fibromyalgia; swallowing disorders are not a primary symptom of this condition.

Correct Answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

Correct Answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.
