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. An infant weighs 7 pounds at birth. What is the expected weight by 1 year of age?

• A. 10 pounds
• B. 12 pounds
• C. 18 pounds
• D. 21 pounds

Correct answer: D

Rationale: A birth weight of 7 pounds typically triples by the age of 1 year, resulting in an expected weight of 21 pounds. This significant weight gain is a normal growth pattern for infants as they usually experience rapid growth in the first year of life. Choices A, B, and C are incorrect because they do not account for the usual growth rate of an infant in the first year. Infants commonly triple their birth weight by the age of 1, making 21 pounds the expected weight.

3. All of the following are common reasons that nurses are reluctant to delegate except:

• A. lack of self-confidence
• B. desire to maintain authority
• C. confidence in subordinate
• D. getting trapped in the 'I can do it better myself' mindset

Correct answer: C

Rationale: If a delegator has confidence in their subordinates and believes a task will be performed correctly, they are more likely to delegate. Reasons nurses may be reluctant to delegate include their own lack of self-confidence, the desire to maintain authority, and getting trapped in the 'I can do it better myself' mindset. Therefore, 'confidence in subordinate' is the exception as it actually encourages delegation. The other choices are common barriers to delegation in healthcare settings.

4. 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.

5. The LPN is teaching a first-time mother about breastfeeding her newborn. Which statement, if made by the mother, would reflect that the teaching had been successful?

• A. "My baby should be having at least 4-6 wet diapers a day until 1 month."?
• B. "It's nice that breastfed babies eat a bit less than formula-fed babies."?
• C. "My baby should be nursing 8-12 times a day during this period."?
• D. "I'm a little nervous about my milk coming in tomorrow. I've heard it's uncomfortable."?

Correct answer: C

Rationale: The correct answer is, '"My baby should be nursing 8-12 times a day during this period."?' This statement indicates successful teaching because newborns should nurse 8-12 times during the newborn period to ensure they receive adequate nutrition and establish a good milk supply. This frequency helps in meeting the baby's demands for growth and development. Choice A is incorrect because while it mentions the appropriate number of wet diapers a day once the mother's milk comes in, it does not reflect successful teaching about breastfeeding frequency. Choice B is incorrect because it discusses feeding amounts in comparison to formula-fed babies, which is not a direct indicator of successful breastfeeding teaching. Choice D is incorrect because it focuses on the mother's concerns about milk coming in, not on understanding the feeding frequency needed for the newborn.
