Nursing Elites

1. The healthcare provider would expect which eating disorder to have the greatest fluctuations in potassium?

• A. Binge eating disorder
• B. Anorexia nervosa
• C. Bulimia
• D. Purge syndrome

Correct answer: C

Rationale: The correct answer is C: Bulimia. Bulimia involves cycles of binge eating and purging, where individuals may induce vomiting or use laxatives and diuretics. These purging behaviors can lead to significant fluctuations in potassium levels due to electrolyte imbalances caused by excessive loss of potassium through vomiting and purging. In contrast, Binge eating disorder (A) does not involve purging behaviors, so it is less likely to cause significant potassium fluctuations. Anorexia nervosa (B) is characterized by severe food restriction rather than purging, leading to a different pattern of electrolyte imbalances. Purge syndrome (D) is not a recognized eating disorder and is not associated with specific patterns of potassium fluctuations seen in bulimia.

2. A client is admitted with the diagnosis of myocardial infarction (MI). Which of the following lab values would be consistent with this diagnosis?

• A. Low serum albumin
• B. High serum cholesterol
• C. Abnormally low white blood cell count
• D. Elevated creatinine phosphokinase (CPK)

Correct answer: D

Rationale: The correct answer is D: Elevated creatinine phosphokinase (CPK). Elevated CPK levels indicate muscle damage, including damage to the cardiac muscle, which aligns with the diagnosis of myocardial infarction. Choice A, low serum albumin, is not directly related to myocardial infarction. Choice B, high serum cholesterol, is more associated with conditions like atherosclerosis rather than acute myocardial infarction. Choice C, abnormally low white blood cell count, is typically not a lab value associated with myocardial infarction; instead, it could suggest other conditions like infections or bone marrow issues.

3. During an initial clinic visit, the nurse is taking the history for a client who wants to confirm her pregnancy. The client's last child has a history of low-birth-weight (LBW). Which additional finding is most important for the nurse to consider?

• A. Cigarette smoking.
• B. African American ethnicity.
• C. Poor nutritional status.
• D. Limited maternal education.

Correct answer: A

Rationale: The correct answer is A: Cigarette smoking. Cigarette smoking is a significant risk factor for low birth weight. Smoking during pregnancy reduces the amount of oxygen available to the baby, leading to LBW. Choice B, African American ethnicity, while it may be a risk factor, is not as directly linked to LBW as cigarette smoking. Choice C, poor nutritional status, can contribute to LBW but is not as significant as cigarette smoking in this case. Choice D, limited maternal education, is an important social determinant of health but is not as directly related to LBW as cigarette smoking.

4. The school RN is assessing a group of middle school students for signs of scoliosis and discovers a female student with noticeable unequal symmetry of the upper and lower back. Which intervention is most important for the RN to implement?

• A. Send the student home
• B. Make a referral to have the scoliosis further evaluated.
• C. Withdraw the student from all physical activities
• D. Tell the student not to carry her backpack on her back

Correct answer: B

Rationale: Referring the student for further evaluation of scoliosis is crucial to confirm the diagnosis and determine the appropriate management plan. Sending the student home (choice A) without proper assessment and intervention is not the best course of action. Withdrawing the student from all physical activities (choice C) is not necessary and may cause unnecessary distress. Instructing the student not to carry her backpack on her back (choice D) does not address the underlying issue of scoliosis and is not the most important intervention at this point.

5. A client with a peptic ulcer is scheduled for a vagotomy and pyloroplasty. The nurse explains that the purpose of this surgery is to:

• A. Increase acid secretion
• B. Reduce acid secretion
• C. Promote gastric emptying
• D. Remove the ulcerated area

Correct answer: B

Rationale: The correct answer is B: "Reduce acid secretion." Vagotomy is performed to reduce acid secretion by cutting the vagus nerve, which stimulates acid production. Choices A, C, and D are incorrect. A vagotomy does not increase acid secretion, promote gastric emptying, or remove the ulcerated area. It specifically aims to decrease acid production to help in the healing of peptic ulcers.
