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 sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?

• A. In most cases, breast cancer is not caused by the BRCA gene.
• B. It depends on how you will feel if the test is positive for the BRCA gene.
• C. There are many things to consider before deciding to have genetic testing.
• D. You should decide first whether you are willing to have a bilateral mastectomy.

Correct answer: C

Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.

3. The mother of a 9-month-old who was diagnosed with respiratory syncytial virus (RSV) yesterday calls the clinic to inquire if it will be all right to take her infant to the first birthday party of a friend's child the following day. What response should the nurse provide this mother?

• A. The child can be around other children but should wear a mask at all times.
• B. The child will no longer be contagious, no need to take any further precautions.
• C. Make sure there are no children under the age of 6 months around the infected child.
• D. Do not expose other children. RSV is very contagious even without direct oral contact.

Correct answer: D

Rationale: The correct response is to advise the mother not to expose other children to the infected child. RSV is highly contagious, and transmission can occur even without direct oral contact. It is crucial to prevent the spread of the virus to protect other children from getting infected.

4. What is the primary cause of jaundice in a client with liver cirrhosis?

• A. Decreased bile production
• B. Increased bilirubin levels
• C. Hepatic inflammation
• D. Portal hypertension

Correct answer: B

Rationale: Jaundice in a client with liver cirrhosis is primarily caused by increased bilirubin levels. In liver cirrhosis, impaired liver function leads to the accumulation of bilirubin in the blood, resulting in jaundice. Bilirubin is a yellow pigment produced from the breakdown of red blood cells, and its elevation is a common manifestation of liver dysfunction. Choices A, C, and D are incorrect. While decreased bile production can contribute to jaundice, in liver cirrhosis, the key factor is the buildup of bilirubin due to liver dysfunction, not a decrease in bile production. Hepatic inflammation and portal hypertension are associated with liver cirrhosis but are not the primary causes of jaundice in this context.

5. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.
