Biology Test
1. Which of the following options correctly lists biology's hierarchical organizational system?
- A. Phylum, Kingdom, Class, Family, Order, Species, Genus
- B. Kingdom, Phylum, Class, Order, Family, Genus, Species
- C. Genus, Order, Kingdom, Class, Phylum, Species, Family
- D. Class, Phylum, Kingdom, Genus, Order, Family, Species
Correct answer: B
Rationale: The correct hierarchical organizational system in biology is Kingdom, Phylum, Class, Order, Family, Genus, and Species. This follows the mnemonic 'King Phillip Came Over For Good Soup.' Choice A is incorrect as it does not follow the correct hierarchical order. Choice C is incorrect as it starts with Genus, which is more specific and should come after Family. Choice D is incorrect as it does not follow the correct hierarchical order.
2. A mother brings her 6-year-old child, who has just stepped on a rusty nail, to the pediatrician's office. Upon inspection, the nurse notes that the nail went through the shoe and pierced the bottom of the child's foot. Which action should the nurse implement first?
- A. Cleanse the foot with soap and water and apply an antibiotic ointment
- B. Provide teaching about the need for a tetanus booster within the next 72 hours.
- C. Have the mother check the child's temperature every 4 hours for the next 24 hours
- D. Transfer the child to the emergency department to receive a gamma globulin injection
Correct answer: A
Rationale: The correct first action for the nurse to implement is to cleanse the foot with soap and water and apply an antibiotic ointment to prevent infection. In cases of puncture wounds like stepping on a rusty nail, the immediate concern is to reduce the risk of infection. Providing teaching about the need for a tetanus booster within the next 72 hours is important as well, but it should come after the wound is cleansed. Checking the child's temperature and transferring to the emergency department for a gamma globulin injection are not the immediate priorities in this scenario.
3. The client is being taught to select foods rich in potassium to help prevent digitalis toxicity. Which choice indicates the client understands dietary needs?
- A. Three apricots
- B. Medium banana
- C. Naval orange
- D. Baked potato
Correct answer: D
Rationale: The correct answer is D. A baked potato is high in potassium and helps prevent digitalis toxicity by maintaining adequate potassium levels. While choices A, B, and C all contain some potassium, a baked potato is a more concentrated source of potassium compared to three apricots, a medium banana, or a naval orange. Therefore, the client should choose a baked potato to better meet the dietary needs for preventing digitalis toxicity.
4. During an annual physical at a corporate clinic, a male employee tells the nurse that his high-stress job is causing trouble in his personal life. He further explains that he often gets so angry while driving to and from work that he has considered “getting even” with other drivers. How should the nurse respond?
- A. “Anger is contagious and could result in a major confrontation.”
- B. “Try not to let your anger cause you to act impulsively.”
- C. “Expressing your anger to a stranger could result in an unsafe situation.”
- D. “It sounds as if there are many situations that make you feel angry.”
Correct answer: B
Rationale: The correct response is to encourage the client to manage their anger and avoid impulsive actions, as stated in choice B. This approach helps the individual recognize the potential consequences of acting on their anger impulsively. Choice A is not the best response because it focuses on the contagious nature of anger rather than addressing the individual's behavior. Choice C is incorrect as it only highlights the potential dangers of expressing anger to a stranger without providing guidance on managing the underlying issue. Choice D acknowledges the client's feelings but does not offer practical advice on how to address the anger and potential impulsive actions.
5. A client who is taking ciprofloxacin (Cipro) reports to the nurse of having a loss of appetite and a metallic taste in the mouth. What action should the nurse implement?
- A. Reassure the client that these are common side effects of ciprofloxacin.
- B. Instruct the client to take ciprofloxacin with food.
- C. Notify the healthcare provider of the client's symptoms.
- D. Encourage the client to increase fluid intake.
Correct answer: C
Rationale: The correct action for the nurse to take when a client on ciprofloxacin reports loss of appetite and a metallic taste in the mouth is to notify the healthcare provider of the client's symptoms. These symptoms could indicate a need for a change in medication or additional treatment, which the healthcare provider would need to assess. Instructing the client to take ciprofloxacin with food (choice B) may help with gastrointestinal upset but will not address the reported symptoms. Reassuring the client (choice A) is important for providing emotional support but does not address the need for further evaluation. Encouraging increased fluid intake (choice D) is generally beneficial but may not directly address the specific side effects reported.
