Biology Practice Test
1. Prophase is the first stage of mitosis. Which of the following best describes chromosomes during this stage?
- A. They are gathered on either side of the separating cell
- B. They are all aligned along the metaphase plate
- C. They are attached to the spindle
- D. They are visibly separate
Correct answer: D
Rationale: The correct answer is D. During prophase, the chromosomes condense and become visible as distinct structures under a microscope. Choice A is incorrect as chromosomes are not gathered on either side of the separating cell during prophase. Choice B is incorrect because chromosomes align along the metaphase plate during the subsequent stage, metaphase. Choice C is incorrect as chromosomes become attached to the spindle fibers during prometaphase, the stage following prophase.
2. The healthcare provider is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which intervention is most important?
- A. Restrict fluids to 1,000 mL per day.
- B. Administer a vasopressin antagonist.
- C. Monitor intake and output.
- D. Encourage a high-sodium diet.
Correct answer: B
Rationale: Administering a vasopressin antagonist is the most critical intervention for a client with SIADH. SIADH is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. A vasopressin antagonist helps manage the symptoms by blocking the effects of ADH, promoting water excretion, and restoring electrolyte balance. Restricting fluids (choice A) may exacerbate hyponatremia, monitoring intake and output (choice C) is important but not the most critical intervention, and encouraging a high-sodium diet (choice D) is contraindicated in SIADH due to the risk of worsening hyponatremia.
3. A client with a diagnosis of schizophrenia is exhibiting negative symptoms such as anhedonia and social withdrawal. Which intervention should be a priority for the nurse?
- A. Encourage participation in group activities.
- B. Administer prescribed antipsychotic medication.
- C. Assist the client in setting realistic goals.
- D. Promote engagement in social interactions.
Correct answer: A
Rationale: Encouraging participation in group activities is a priority intervention for a client with schizophrenia exhibiting negative symptoms like anhedonia and social withdrawal. Group activities provide structured social interactions and can help the client gradually re-engage with others, potentially reducing social withdrawal and improving social skills. Administering antipsychotic medication (Choice B) is essential in managing positive symptoms of schizophrenia such as hallucinations and delusions, not negative symptoms like anhedonia and social withdrawal. While assisting the client in setting realistic goals (Choice C) is important for overall care, addressing social withdrawal and anhedonia is more immediate. Promoting engagement in social interactions (Choice D) is beneficial, but encouraging participation in group activities provides a structured and supportive environment that can specifically target the negative symptoms being exhibited.
4. A 3-year-old child is brought to the clinic by the parents who are concerned that the child is not yet potty trained. What is the nurse’s best response?
- A. Most children are potty trained by this age, so you should not be concerned
- B. Every child develops at their own pace. Let’s discuss some strategies to help
- C. Your child may need to be evaluated for developmental delays
- D. It’s best to force your child to use the potty to encourage training
Correct answer: B
Rationale: The correct answer is B because it is important to acknowledge that children develop at different rates. By offering support and discussing strategies for potty training, the nurse can provide the necessary guidance without causing unnecessary concern or pressure on the parents. Choice A is incorrect because it dismisses the parents' concerns. Choice C is incorrect because jumping to the conclusion of developmental delays without further assessment or discussion can cause undue anxiety. Choice D is incorrect because forcing a child to use the potty can lead to resistance and negative associations with potty training.
5. A community health nurse is developing a program to increase physical activity among adults in the community. Which intervention is most likely to be successful?
- A. distributing flyers about the benefits of exercise
- B. organizing free community exercise classes
- C. partnering with local gyms to offer discounts
- D. hosting a health fair with information booths
Correct answer: B
Rationale: Organizing free community exercise classes is the most likely successful intervention as it provides a structured and accessible opportunity for adults to engage in physical activity. This choice directly offers a practical solution by providing a regular and organized setting for individuals to participate in physical activity. Distributing flyers about the benefits of exercise, while informative, may not lead to actual participation. Partnering with local gyms to offer discounts relies on individuals taking the initiative to sign up for gym memberships, which may not be feasible for everyone. Hosting a health fair with information booths is informative but may not directly address the need for increased physical activity among adults in the community.
