Nursing Elites

1. 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.

2. 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.

3. The client is admitted with chronic obstructive pulmonary disease. Blood gases reveal pH 7.36, CO2 45, O2 84, HCO3 28. The nurse would assess the client to be in:

• A. Uncompensated acidosis
• B. Compensated alkalosis
• C. Compensated respiratory acidosis
• D. Uncompensated metabolic acidosis

Correct answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.

4. An elderly client denies that abuse is occurring. Which of the following factors could be a barrier for the client to admit being a victim?

• A. knowledge that elder abuse is rare
• B. personal belief that abuse is deserved
• C. lack of developmentally appropriate screening tools
• D. fear of reprisal or further violence if the incident is reported

Correct answer: D

Rationale: Barriers to reporting elder abuse include victim shame, fear of reprisals, fear of loss of caregiver, and lack of knowledge of agencies that provide services. Many elders fear that reporting abuse results in their placement in long-term care because the current caregiver is the abuser. Choice A is incorrect because knowledge of the frequency of elder abuse is not a significant factor in a victim's reluctance to report. Choice B is also incorrect; while some victims may have feelings of undeservedness, it is not a common primary barrier to reporting abuse. Choice C is incorrect as the lack of appropriate screening tools may hinder identification but is not a significant barrier for the client to admit being a victim. Therefore, the correct answer is D, as the fear of reprisal or further violence if the incident is reported is a common and significant barrier for elderly clients to admit being a victim.

5. 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.
