Nursing Elites

1. A client is taking hydrocodone (Vicodin) for chronic back pain. The client has required an increase in the dose and asks whether this means he is addicted to Vicodin. The nurse should base her reply on the knowledge that:

• A. the client's body has developed tolerance, requiring more drug to produce the same effect.
• B. the client is preoccupied with getting the drug and is experiencing loss of control, indicating drug dependence.
• C. addiction is the term used to describe physical dependence with withdrawal symptoms and tolerance.
• D. the client has a dual diagnosis of substance abuse and chronic back pain

Correct answer: A

Rationale: Drug tolerance is characterized by the ability to ingest a larger dose without adverse effects and decreased sensitivity to the substance. In this scenario, the client needing an increased dose of hydrocodone to achieve the same pain relief indicates tolerance developing, not addiction. Choice B is incorrect as it describes drug dependence, where the individual is preoccupied with the drug and has a loss of control. Choice C is incorrect because addiction involves psychological behaviors related to substance use, not just physical dependence with withdrawal symptoms and tolerance. Choice D is incorrect as it refers to a dual diagnosis, which is the coexistence of substance abuse and psychiatric disorders, not the development of tolerance to a drug.

2. A client with cancer is to undergo an intravenous pyelogram. The nurse should:

• A. Ensure adequate fluid intake 24 hours before the procedure
• B. Ask the client to void immediately before the study
• C. Administer medication that affects the central nervous system as prescribed
• D. Position the client appropriately for the procedure

Correct answer: B

Rationale: The correct answer is to ask the client to void immediately before the study. For an intravenous pyelogram, the client may have orders for laxatives or enemas, so ensuring the client voids before the test is important to prevent obscuring visualization of the kidney, ureters, and bladder. Choice A is incorrect because there is no need to force fluids before the procedure. Choice C is incorrect as medications affecting the central nervous system should not be held unless specified by the healthcare provider. Choice D is incorrect as covering the reproductive organs with an x-ray shield is not necessary for an intravenous pyelogram.

3. 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.

4. The client is scheduled for a Tensilon test to check for Myasthenia Gravis. Which medication should be kept available during the test?

• A. Atropine sulfate
• B. Furosemide
• C. Prostigmin
• D. Promethazine

Correct answer: A

Rationale: During a Tensilon test to check for Myasthenia Gravis, Atropine sulfate should be kept available as it is the antidote for Tensilon and is administered to manage cholinergic crises that may occur during the test. Atropine sulfate helps counteract the excessive stimulation of the parasympathetic nervous system caused by Tensilon. Furosemide (choice B) is a diuretic and not related to managing Tensilon-induced crises. Prostigmin (choice C) is used to treat Myasthenia Gravis itself, not for managing the effects of Tensilon. Promethazine (choice D) is an antiemetic and antianxiety agent, which is not necessary for a Tensilon test. Therefore, Atropine sulfate (choice A) is the correct medication to have available during a Tensilon test, making choices B, C, and D incorrect in this context.

5. The doctor orders 2% nitroglycerin ointment in a 1-inch dose every 12 hours. Proper application of nitroglycerin ointment includes:

• A. Rotating application sites
• B. Limiting applications to the chest
• C. Rubbing it into the skin
• D. Covering it with a thin paper dressing

Correct answer: A

Rationale: Proper application of nitroglycerin ointment involves rotating application sites to prevent skin irritation. It should be applied to the back and upper arms, not restricted to the chest, making option B incorrect. Rubbing it into the skin, as indicated in option C, is not recommended for nitroglycerin ointment as it can lead to faster absorption and potential side effects. The correct way is to cover it with a thin paper dressing, not gauze as mentioned in option D, to ensure proper absorption and prevent the medication from evaporating too quickly.
