Nursing Elites

1. A preschooler has successfully completed the test item 'counts 5 blocks' on the Denver II test. This pass is evidence of which of the following developmental concepts?

• A. centration
• B. causality
• C. nonreversibility
• D. conservation

Correct answer: D

Rationale: The ability of a preschooler to move five blocks to a piece of paper and state there are five blocks on the paper is evidence that the preschooler has the ability of conservation. This concept refers to the fact that the quantity of something doesn't change just because the shape, contour, and so on has changed. Five blocks are still five blocks, whether they are lying beside the paper, stacked on the paper, or moved to the paper. Centration is the ability to concentrate on one feature of a situation while neglecting all other aspects. Causality is based on the sequence of events, one event ordinarily following another. Non-reversibility refers to the inability of preschoolers to reverse their operations. They are only able to think forward, not retrace or reverse their thought processes.

2. When preparing to listen to a client's breath sounds, what technique should a nurse use?

• A. Ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap.
• B. Listen to the right lung first, then the left lung, moving from top to bottom systematically.
• C. Ask the client to take deep breaths through the mouth.
• D. Use the diaphragm of the stethoscope, holding it firmly against the client's chest.

Correct answer: D

Rationale: When preparing to listen to a client's breath sounds, a nurse should ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little more deeply than usual but to stop if feeling dizzy. The nurse should use the flat diaphragm end-piece of the stethoscope, holding it firmly on the chest wall. By using the diaphragm, the nurse can listen for at least one full respiration in each location, moving from side to side to compare sounds. This technique ensures a systematic and thorough assessment of lung sounds. Choice A is correct as it includes the proper positioning of the client and specifies the use of the diaphragm of the stethoscope. Choice B is incorrect as both lungs should be auscultated systematically, starting from the top and moving down. Choice C is incorrect as deep breaths, not shallow ones, are recommended for an accurate assessment of breath sounds.

3. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

4. An LPN is reviewing medication lists for several clients recently admitted to the hospital. Which of the following scenarios would be least concerning?

• A. A client taking allopurinol for gout states they have been taking black cohosh to help with post-menopausal symptoms.
• B. A client has an order for warfarin and states they have been taking Ginkgo biloba to improve their memory.
• C. A client taking Lipitor states they have been taking ginseng for an energy boost.
• D. A client has a prescription for an SSRI and states they have been taking St. John's wort to also help with their depression.

Correct answer: C

Rationale: The least concerning scenario is when a client taking Lipitor states they have been taking ginseng for an energy boost. While ginseng may cause an increased risk of bleeding, it should not interact with Lipitor. On the other hand, St. John's wort should not be taken with an SSRI as it may cause serotonin syndrome, posing a more serious concern. Black cohosh should not be taken with allopurinol as they can both cause hepatotoxicity, especially in combination. Ginkgo biloba should not be taken with warfarin as it causes an increased risk of bleeding, making it a more concerning scenario compared to the client taking Lipitor and ginseng.

5. An assessment of the skull of a normal 10-month-old baby should identify which of the following?

• A. closure of the posterior fontanel.
• B. closure of the anterior fontanel.
• C. overlap of cranial bones.
• D. ossification of the sutures

Correct answer: A

Rationale: The correct answer is the closure of the posterior fontanel. By 10 months of age, the posterior fontanel should be closed. The anterior fontanel typically closes around 12-18 months of age. Overlapping of cranial bones is not a normal finding and may indicate craniosynostosis, a condition where the sutures close too early. Ossification of the sutures is also not a normal finding in a 10-month-old baby as the sutures should remain open to allow for the growth of the skull.
