Nursing Elites

1. When medications have an additive, synergistic, or antagonistic effect on a tissue, a ________ reaction has occurred.

• A. pharmaceutical
• B. pharmacodynamic
• C. pharmacokinetic
• D. drug incompatibility

Correct answer: B

Rationale: The correct answer is 'pharmacodynamic.' Pharmacodynamics pertain to the effect of a drug on receptors, explaining how drugs affect tissues. Pharmaceutical reactions refer to chemical reactions between drugs before administration or absorption, not their effect on tissues. Pharmacokinetic reactions involve how the body affects the drug, not the tissue. Drug incompatibilities are essentially pharmaceutical reactions, not the specific effects on tissues seen in pharmacodynamic reactions.

2. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

3. A successful resolution of the nursing diagnosis Negative Self-Concept (related to unrealistic self-expectations) is when the client can:

• A. report a positive self-concept.
• B. identify negative thoughts.
• C. recognize positive thoughts.
• D. give one positive cue with each negative cue

Correct answer: A

Rationale: The correct answer is to 'report a positive self-concept.' The problem statement is Negative Self-Concept, so the goal is for the client to achieve a positive self-concept. This involves helping the client recognize their worth and strengths. Choices B, C, and D do not directly address the resolution of Negative Self-Concept. Identifying negative thoughts (B) is a step towards improvement but does not represent a successful resolution. Recognizing positive thoughts (C) is positive but not the primary goal in addressing Negative Self-Concept. 'Give one positive cue with each negative cue' (D) is not as comprehensive as achieving an overall positive self-concept.

4. 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.

5. Tricyclics (Antidepressants) can sometimes have which of the following adverse effects on patients diagnosed with depression?

• A. Shortness of breath
• B. Fainting
• C. Large intestine ulcers
• D. Distal muscular weakness

Correct answer: B

Rationale: The correct answer is 'Fainting.' Tricyclic antidepressants can cause fainting and hypotension as adverse effects. Shortness of breath (Choice A) is not a common side effect of tricyclics. Large intestine ulcers (Choice C) are not typically associated with tricyclic antidepressants. Distal muscular weakness (Choice D) is not a common adverse effect of tricyclics but is commonly associated with other medications.
