Nursing Elites

1. Lidocaine is a medication frequently ordered for the client experiencing

• A. Atrial tachycardia
• B. Ventricular tachycardia
• C. Heart block
• D. Ventricular bradycardia

Correct answer: B

Rationale: Lidocaine is used to treat ventricular tachycardia. This medication slowly exerts an antiarrhythmic effect by increasing the electrical stimulation threshold of the ventricles without depressing the force of ventricular contractions. It is not used for atrial arrhythmias; thus, answer A is incorrect. Answers C and D are incorrect because lidocaine does not slow the heart rate, so it is not used for heart block or bradycardia.

2. The nurse is caring for a client with epilepsy who is being treated with carbamazepine (Tegretol). Which laboratory value might indicate a serious side effect of this drug?

• A. Uric acid of 5 mg/dL
• B. Hematocrit of 33%
• C. WBC 2,000 per cubic millimeter
• D. Platelets 150,000 per cubic millimeter

Correct answer: C

Rationale: Carbamazepine (Tegretol) can suppress the bone marrow, leading to a decrease in the white blood cell count. A laboratory value of WBC 2,000 per cubic millimeter indicates a serious side effect of the drug. Choices A and D are within normal limits, while choice B is at the lower limit of normal. Therefore, choices A, B, and D are incorrect.

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. A new nursing graduate indicates in charting entries that he is a licensed practical nurse, although he has not yet received the results of the licensing exam. The graduate's action can result in what type of charge?

• A. Fraud
• B. Tort
• C. Malpractice
• D. Negligence

Correct answer: A

Rationale: The correct answer is 'Fraud.' Identifying oneself as a nurse without a license defrauds the public and can lead to prosecution. A tort is a wrongful act in breach of a legal duty imposed by law; malpractice is the failure to act appropriately as a nurse or acting in a way that harm comes to the client; and negligence is failing to perform care. In this scenario, the key issue is the misrepresentation of licensure status, which constitutes fraud. Therefore, choices B, C, and D are incorrect.

5. A client is admitted with a diagnosis of Multiple Drug Use. The nurse should plan care based on knowledge that

• A. Multiple drug use is common.
• B. People might use more than one drug to enhance the effect or relieve withdrawal symptoms.
• C. Combining alcohol and barbiturates can be dangerous due to their combined depressant effects.
• D. Assessment and intervention are more complex with multiple drug use due to the synergistic effects.

Correct answer: B

Rationale: When caring for a client with Multiple Drug Use, it is important to understand that individuals may use more than one drug simultaneously or sequentially to enhance the effect of a particular drug or to relieve withdrawal symptoms. This practice is common among substance users. For example, heroin users may also consume alcohol, marijuana, or benzodiazepines. Combining drugs can have various effects, such as intensifying intoxication or alleviating withdrawal symptoms. It is crucial to recognize that multiple drug use can complicate assessment and intervention due to the diverse effects of different substances on the client's health. Option A is incorrect as multiple drug use is indeed common, not uncommon. Option C is incorrect because combining alcohol and barbiturates can be dangerous due to their combined depressant effects. Option D is incorrect because multiple drug use complicates assessment and intervention rather than making them easier, as the effects of different drugs on the client need to be carefully considered.
