Nursing Elites

1. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

2. A 30-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The clinical presentation of a 30-year-old woman with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria is highly suggestive of type 1 diabetes mellitus. Type 1 diabetes mellitus is characterized by autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and subsequent hyperglycemia. The presence of ketonuria indicates the breakdown of fats for energy due to the lack of insulin. In contrast, type 2 diabetes mellitus typically presents with gradual onset and is often associated with insulin resistance rather than absolute insulin deficiency. Diabetes insipidus is characterized by polyuria and polydipsia but is not associated with hyperglycemia or ketonuria. Hyperthyroidism may present with symptoms like fatigue but does not typically cause hyperglycemia or ketonuria.

3. 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.

4. A client with heart failure is prescribed digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse teach the client to report?

• A. Increased appetite.
• B. Yellow or blurred vision.
• C. Weight gain.
• D. Nasal congestion.

Correct answer: B

Rationale: Yellow or blurred vision is a hallmark sign of digoxin toxicity. Digoxin toxicity can affect various body systems, but visual disturbances, such as yellow or blurred vision, are important signs that the client should report immediately. Other signs like increased appetite, weight gain, or nasal congestion are not typically associated with digoxin toxicity. Prompt reporting of visual disturbances can help prevent further complications associated with digoxin toxicity.

5. A 9-year-old female client was recently diagnosed with diabetes mellitus. Which symptom will her parents most likely report?

• A. Refuses to eat her favorite meals at home.
• B. Drinks more soft drinks than previously.
• C. Voids only one or two times per day.
• D. Gained 10 pounds within one month.

Correct answer: B

Rationale: The correct answer is B. Increased thirst and fluid intake, such as drinking more soft drinks than previously, is a common symptom of diabetes mellitus in children. This increased thirst is due to the body trying to eliminate excess sugar through urination, leading to dehydration and the need for more fluids. The other choices are less likely to be directly related to the diagnosis of diabetes mellitus in this scenario.
