HESI Leadership and Management Quizlet
1. A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?
- A. Start oxygen at 2 L/min
- B. Initiate cardiac monitoring
- C. Initiate seizure precautions
- D. Keep the patient on bed rest
Correct answer: B
Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.
2. Which of the following chronic complications is associated with diabetes?
- A. Dizziness, dyspnea on exertion, and coronary artery disease.
- B. Retinopathy, neuropathy, and coronary artery disease.
- C. Leg ulcers, cerebral ischemic events, and pulmonary infarcts.
- D. Fatigue, nausea, vomiting, muscle weakness, and cardiac arrhythmias.
Correct answer: B
Rationale: The correct answer is B. Diabetes is associated with chronic complications such as retinopathy, neuropathy, and coronary artery disease. Choice A includes symptoms rather than chronic complications of diabetes. Choice C lists conditions not typically associated with diabetes. Choice D describes symptoms that may occur in various medical conditions but are not specific chronic complications of diabetes.
3. Which of the following is an example of a chronic disease?
- A. Common cold
- B. Influenza
- C. Diabetes
- D. Food poisoning
Correct answer: C
Rationale: Diabetes is classified as a chronic disease because it is a long-term condition that requires ongoing management. Choices A, B, and D, which are the common cold, influenza, and food poisoning, are acute illnesses that typically resolve on their own without long-lasting implications.
4. Which of the following joints normally allows 360-degree circumflexion?
- A. The knee
- B. The shoulder
- C. The elbow
- D. The fingertips
Correct answer: B
Rationale: The correct answer is B: The shoulder. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion, including 360-degree circumflexion. This joint provides flexibility and mobility in various directions. Choice A, the knee joint, primarily allows flexion and extension but does not have a 360-degree circumflexion. Choice C, the elbow joint, is a hinge joint that permits flexion and extension but not circumflexion. Choice D, the fingertips, do not form a specific joint that allows circumflexion; rather, they have joints that enable bending and straightening movements.
5. Which of the following differentiates ulcerative colitis from Crohn's disease?
- A. Crohn's disease primarily affects the left colon and rectum, while ulcerative colitis most often affects the right colon and distal ileum.
- B. Crohn's disease presents with shallow ulcerations, whereas ulcerative colitis presents with a cobblestone appearance of the mucosal lining.
- C. The extent of involvement is noncontiguous and segmented with Crohn's disease, whereas it is contiguous and diffuse with ulcerative colitis.
- D. Crohn's disease has primarily mucosal involvement, whereas it is transmural with ulcerative colitis.
Correct answer: C
Rationale: The correct answer is C. Crohn's disease is characterized by noncontiguous, segmented involvement, meaning it can affect different areas with healthy tissue in between, while ulcerative colitis involves continuous areas of inflammation. Choices A, B, and D are incorrect because Crohn's disease can affect any part of the digestive tract from mouth to anus, can present with shallow ulcerations or deep fissures, and is transmural, meaning it affects the entire thickness of the bowel wall. On the other hand, ulcerative colitis typically affects the colon and rectum, presents with a continuous pattern of inflammation, and primarily involves the mucosal lining of the colon.
