Nursing Elites

1. A client with cancer is admitted to the oncology unit. Stat lab values reveal Hgb 12.6, WBC 6500, K+ 1.9, uric acid 7.0, Na+ 136, and platelets 178,000. The nurse evaluates that the client is experiencing which of the following?

• A. Hypernatremia
• B. Hypokalemia
• C. Myelosuppression
• D. Leukocytosis

Correct answer: B

Rationale: The correct answer is 'Hypokalemia.' The potassium level of 1.9 indicates low potassium levels, a condition known as hypokalemia. The other lab values are within normal ranges: Hgb 12.6, WBC 6500, uric acid 7.0, Na+ 136, and platelets 178,000. Hypernatremia (choice A) refers to high sodium levels, which are not present in this case. Myelosuppression (choice C) is a decrease in bone marrow activity, which is not indicated by the lab values provided. Leukocytosis (choice D) is an increase in white blood cells, which is also not present based on the given values.

2. What is the purpose of a contract between a nurse and a client?

• A. Contracts specify the participation and responsibilities of both parties.
• B. Contracts indicate the feeling tone established between participants.
• C. Contracts are legally binding and prevent either party from ending the relationship prematurely.
• D. Contracts define the roles the participants take.

Correct answer: A

Rationale: The purpose of a contract between a nurse and a client is to specify the participation and responsibilities of both parties. It outlines the expectations, contributions, and duties of each party involved in the professional relationship. This ensures clarity and mutual understanding. Choice B is incorrect as contracts do not indicate feeling tone but rather focus on the professional aspects. Choice C is incorrect because while contracts are legally binding, their primary purpose is not to prevent premature termination but to establish guidelines. Choice D is incorrect as contracts focus more on responsibilities and participation rather than specific roles.

3. A teenage client is admitted to the hospital because of an acetaminophen (Tylenol) overdose. Overdoses of acetaminophen can precipitate life-threatening abnormalities in which of the following organs?

• A. lungs
• B. liver
• C. kidneys
• D. adrenal glands

Correct answer: B

Rationale: Acetaminophen is extensively metabolized in the liver. An acetaminophen overdose can lead to severe liver damage and even liver failure, which can be life-threatening. Choices A, C, and D are incorrect. Acetaminophen overdose does not typically cause life-threatening problems in the lungs, kidneys, or adrenal glands. While prolonged acetaminophen use may increase the risk of renal dysfunction, a single overdose primarily affects the liver.

4. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

5. After a client undergoes a left lower lobe lung resection for lung cancer, which post-operative measure would typically be included in the plan?

• A. Closed chest drainage
• B. A tracheostomy
• C. A mediastinal tube
• D. Percussion vibration and drainage

Correct answer: A

Rationale: After a lung resection, such as the removal of the left lower lobe for lung cancer, closed chest drainage is a common post-operative measure to help drain any excess air or fluid from the chest cavity. A tracheostomy is not typically needed for this procedure, so choice B is incorrect. Similarly, a mediastinal tube is not routinely inserted following a left lower lobe lung resection, making choice C incorrect. Percussion vibration and drainage are not indicated for this type of surgery, so choice D is also incorrect. Therefore, the correct answer is closed chest drainage.
