Nursing Elites

1. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture.
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

2. Where do the vast majority of deaths resulting from unintentional poisoning occur?

• A. Infants
• B. Toddlers
• C. Teens
• D. Adults

Correct answer: B

Rationale: The correct answer is 'Toddlers.' Toddlers are at the highest risk of unintentional poisoning due to their natural curiosity, explorative behavior, and lack of awareness of potential dangers. Infants are typically closely monitored, teens are more aware of risks, and adults generally have better judgment and understanding of hazardous substances, making them less susceptible to unintentional poisoning. Therefore, toddlers, being inquisitive and unaware of risks, are the most vulnerable group in terms of unintentional poisoning incidents.

3. A nurse and a nursing assistant enter a client's room to provide care and find the client lying on the floor. Which action should the nurse take first?

• A. Ask the nursing assistant to complete an incident report
• B. Check the client's level of consciousness and vital signs
• C. Contact the unit secretary on the intercom and ask that the client's health care provider be called
• D. Ask the nursing assistant to assist in getting the client back to bed

Correct answer: B

Rationale: When a client sustains a fall, the nurse must first assess the client. The nurse should check the client's level of consciousness and vital signs to determine the severity of the situation and provide appropriate care promptly. This immediate assessment is crucial in ensuring the client's immediate needs are addressed. Asking the nursing assistant to complete an incident report (choice A) is not the priority as the client's condition needs immediate attention. Contacting the unit secretary to call the client's health care provider (choice C) can be done after the initial assessment has been completed. Asking the nursing assistant to assist in getting the client back to bed (choice D) should only be considered after ensuring the client is stable and safe to move.

4. The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

• A. help decrease stimuli from the cerebral cortex.
• B. stimulate hormonal changes in the brain.
• C. help the client's circadian rhythm.
• D. alert the hypothalamus in the brain.

Correct answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

5. When are standard walkers typically used?

• A. When clients have poor balance, cannot stand up, have weak arms, and good hand strength.
• B. When clients have poor balance, have a broken leg, or have experienced amputation.
• C. When clients have poor balance, have cardiac problems, or cannot use crutches or a cane.
• D. When clients have poor balance, have an autoimmune disease, or have weak arms.

Correct answer: C

Rationale: Standard walkers are typically used for clients who have poor balance, cardiac problems, or those who cannot use crutches or a cane. The rationale is correct in stating that a walker is suitable for individuals needing to bear partial weight and having strength in their wrists and arms to propel the walker forward. Choices A, B, and D are incorrect because they do not accurately reflect the main reasons why standard walkers are used in clinical practice. Using a walker is not solely about having weak arms, good hand strength, a broken leg, experienced amputation, or an autoimmune disease. The primary focus is on addressing balance issues, cardiac problems, or the inability to use crutches or a cane effectively.
