Nursing Elites

1. 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.

2. A client with schizophrenia says, 'I'm away for the day ... but don't think we should play "? or do we have feet of clay?' Which alteration in the client's speech does the nurse document?

• A. Neologism
• B. Word salad
• C. Clang association
• D. Associative looseness

Correct answer: D

Rationale: The correct answer is 'Associative looseness.' In the provided speech, the client shows associative looseness by making loose connections between phrases without a clear logical link. Clang association involves rhyming words without regard for their meaning. Neologism refers to made-up words with specific meaning to the client, and word salad is a jumble of words that lack coherence either to the listener or the client. Understanding these speech patterns associated with schizophrenia is crucial in identifying the specific alteration in speech displayed by the client in this scenario.

3. How can medication bound to protein affect drug availability?

• A. enhanced drug availability
• B. rapid distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. increased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.

4. Which of the following roommates would be most suitable for the client with myasthenia gravis?

• A. A client with hypothyroidism
• B. A client with Crohn's disease
• C. A client with pyelonephritis
• D. A client with bronchitis

Correct answer: A

Rationale: The most suitable roommate for the client with myasthenia gravis is the client with hypothyroidism because they are quiet. A client with Crohn's disease (choice B) would be up to the bathroom frequently due to gastrointestinal issues, which could disturb the roommate with myasthenia gravis. A client with pyelonephritis (choice C) suffering from a kidney infection will need to urinate frequently, causing disturbances. A client with bronchitis (choice D) will be coughing, potentially disrupting the rest and quiet environment needed by a roommate with myasthenia gravis to manage their symptoms effectively.

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.
