Nursing Elites

1. The client with schizophrenia has become disruptive and requires seclusion. Which staff member can institute seclusion?

• A. The security guard
• B. The registered nurse
• C. The licensed practical nurse
• D. The nursing assistant

Correct answer: B

Rationale: The registered nurse is the correct choice to institute seclusion for a client with schizophrenia. In healthcare settings, only a registered nurse or a physician can legally initiate seclusion. The security guard, licensed practical nurse, and nursing assistant do not have the authority to carry out this action. Therefore, options A, C, and D are incorrect.

2. Before administering Theodur to a 10-year-old being treated for asthma, the nurse should check the:

• A. Urinary output
• B. Blood pressure
• C. Pulse
• D. Temperature

Correct answer: C

Rationale: The correct answer is to check the pulse. Theodur is a bronchodilator used in asthma treatment, and one of the side effects is tachycardia (increased heart rate). Therefore, it is essential to assess the pulse rate before administering Theodur to monitor for any potential tachycardia. Checking urinary output (Choice A), blood pressure (Choice B), and temperature (Choice D) are not directly related to the immediate side effects of bronchodilators like Theodur in this context, making them unnecessary assessments.

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. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

5. 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.
