Nursing Elites

1. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.

2. The community health nurse is working in a multi-ethnic health center. In what situation should the nurse intervene?

• A. An Asian-American mother reports using cupping to treat an infection, resulting in a pattern of red round marks on her toddler's back.
• B. A Hispanic pregnant client who is often late for appointments arrives late for today's appointment.
• C. A Native-American individual being interviewed will not make direct eye contact when asked about violence in the home.
• D. An African-American infant who is spitting up milk has lost 6 ounces since last week's clinic visit.

Correct answer: D

Rationale: The correct answer is D because losing weight in an infant, especially when combined with spitting up milk, requires immediate intervention to address potential health concerns. Choice A deals with a cultural practice that may not necessarily pose an immediate health risk. Choice B, while important, does not present an immediate health threat. Choice C relates to cultural differences in communication and does not necessarily indicate a need for immediate intervention in terms of health.

3. A 60-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Hepatitis C
• B. Primary biliary cirrhosis
• C. Hemochromatosis
• D. Wilson's disease

Correct answer: B

Rationale: The symptoms of fatigue, pruritus, jaundice, and elevated bilirubin and alkaline phosphatase levels are classic features of primary biliary cirrhosis, an autoimmune liver disease. Hepatitis C typically presents with different symptoms and findings, such as specific viral markers. Hemochromatosis and Wilson's disease involve iron overload and copper accumulation, respectively, leading to distinct clinical and laboratory findings, which do not match the presentation described in this case.

4. A patient who is diagnosed with cervical cancer that is classified as Tis, N0, M0 asks the nurse what the letters and numbers mean. Which response by the nurse is most appropriate?

• A. The cancer involves only the cervix.
• B. The cancer cells closely resemble normal cells.
• C. Further testing is necessary to determine the spread of the cancer.
• D. Determining the original site of the cervical cancer is challenging.

Correct answer: A

Rationale: The correct response is A: 'The cancer involves only the cervix.' In staging, 'Tis' indicates cancer in situ, which means it is localized to the cervix and not invasive at this time. The differentiation of cancer cells is not part of clinical staging. Since the cancer is in situ, its origin is the cervix. Further testing is not required as the cancer has not spread beyond the cervix. Choice B is incorrect as the staging information provided does not relate to the resemblance of cancer cells to normal cells. Choice C is incorrect because further testing is not necessary as the cancer is localized. Choice D is incorrect because the staging information provided clearly indicates the site of origin as the cervix.

5. A 28-year-old woman presents with abdominal pain, bloating, and diarrhea. She notes that her symptoms improve with fasting. She has a history of iron deficiency anemia. What is the most likely diagnosis?

• A. Irritable bowel syndrome
• B. Celiac disease
• C. Lactose intolerance
• D. Crohn's disease

Correct answer: B

Rationale: The symptoms of abdominal pain, bloating, diarrhea improving with fasting, and a history of iron deficiency anemia are characteristic of celiac disease. Celiac disease is an autoimmune disorder triggered by gluten consumption, leading to damage in the small intestine. The improvement with fasting may be due to the temporary avoidance of gluten-containing foods. Irritable bowel syndrome, lactose intolerance, and Crohn's disease do not typically present with improvement of symptoms with fasting or have a clear association with iron deficiency anemia.
