1. 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.

2. 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.

3. Why is the intravenous route potentially the most dangerous route of drug administration?

• A. IV infiltration may occur.
• B. it allows for rapid administration of a drug.
• C. rapid administration of a drug can lead to toxicity
• D. it is the most commonly used route in hospitals.

Correct answer: C

Rationale: The correct answer is C: rapid administration of a drug can lead to toxicity. When a drug is administered intravenously, it has 100% bioavailability, entering the bloodstream immediately and increasing the risk of toxicity if not carefully monitored. While IV infiltration (choice A) can cause tissue damage, it is not typically life-threatening. Choice B is incorrect as the speed of administration is not the primary reason for the danger; it is the immediate and full dose reaching the bloodstream. Choice D is incorrect as the popularity of the route does not inherently make it more dangerous.

4. When assisting a client in gaining insight into anxiety, what should the nurse do?

• A. Help the client relate anxiety to specific triggers.
• B. Ask the client to describe events that precede increased anxiety.
• C. Instruct the client to practice relaxation techniques.
• D. Confront the client's resistive behavior.

Correct answer: B

Rationale: To assist a client in gaining insight into anxiety, it is crucial to identify triggers or events that lead to increased anxiety. This approach helps the client recognize causal factors contributing to their anxiety, promoting self-awareness and understanding. Choice A is incorrect because it should focus on triggers rather than specific behaviors. Choice C is incorrect as it emphasizes managing anxiety through relaxation techniques rather than understanding its roots. Choice D is incorrect as it addresses resistive behavior rather than exploring the causes of anxiety.

5. The primary organ for drug elimination is the:

• A. skin
• B. lung(s)
• C. kidney(s)
• D. liver

Correct answer: C

Rationale: The correct answer is the kidney(s) because most drugs are excreted in the urine, either as the parent compound or as drug metabolites. The skin is not the primary organ for drug elimination; only a few drugs are excreted in sweat. The lung(s) primarily excrete volatile gases with expiration, not drugs. While the liver metabolizes drugs, it is the kidney(s) that primarily eliminate drugs through urine, especially those with a molecular weight above 300.
