Biology Test
1. Water is a polar molecule that can be:
- A. cohesive and corrosive
- B. cohesive and adhesive
- C. electrostatic and ionic
- D. repellent and attractive
Correct answer: B
Rationale: Water is a polar molecule due to an uneven distribution of electrons, allowing it to form hydrogen bonds. This property makes water both cohesive (attracted to itself) and adhesive (attracted to other substances). Choice A is incorrect because water is not corrosive; rather, it is a solvent. Choices C and D are incorrect as they do not describe the cohesive and adhesive properties of water.
2. The nurse is preparing an orientation class for new employees at an inner-city clinic that serves a low-income population. Which information should the nurse include in the presentation to these new employees?
- A. A lack of transportation is the major impediment for the clinic's clients.
- B. Basic physiological needs are likely to be unmet in this clinic's client population.
- C. Printed material is less effective for this population that has limited reading skills.
- D. A group education class is often poorly attended by non-compliant clients.
Correct answer: A
Rationale: The correct answer is A. Addressing transportation issues is crucial when working with low-income populations as lack of transportation can be a significant barrier to accessing healthcare services. This information is important for new employees to understand the challenges faced by the clinic's clients and to strategize ways to overcome this barrier. Choices B, C, and D are incorrect because while they may be relevant considerations, addressing transportation barriers should be a priority given its impact on accessing care for this specific population.
3. The nurse is evaluating the health status of an older client. Which finding is most important for the nurse to report to the healthcare provider?
- A. Client reports decreased urine output
- B. Client reports loss of appetite
- C. Client reports pain in the lower back
- D. Client reports a persistent cough
Correct answer: C
Rationale: Pain in the lower back is a significant finding in an older client as it can indicate underlying issues such as kidney problems, spinal issues, or even aortic aneurysm. These conditions can be serious and require prompt medical attention. Decreased urine output (choice A) could indicate dehydration or kidney issues but is not as urgent as lower back pain. Loss of appetite (choice B) may be concerning but is not as critical as the potential life-threatening conditions associated with lower back pain. A persistent cough (choice D) is important to assess but is generally not as urgent as the potential serious implications of lower back pain in an older client.
4. A male client is admitted to the psychiatric unit for recurrent negative symptoms of chronic schizophrenia and medication adjustment of risperidone (Risperdal). When the client walks to the nurse’s station in a literally contracted position, he states that something has made his body contort into a monster. What action should the nurse take?
- A. Medicate the client with the prescribed antipsychotic thioridazine (Mellaril).
- B. Offer the client a prescribed physical therapy hot pack for muscle spasms.
- C. Direct the client to occupational therapy to distract him from somatic complaints.
- D. Administer the prescribed anticholinergic benztropine (Cogentin) for dystonia.
Correct answer: D
Rationale: The correct action for the nurse to take in this situation is to administer the prescribed anticholinergic benztropine (Cogentin) for dystonia. The client's symptoms of body contortion and feeling like a monster are indicative of acute dystonia, which can be a side effect of antipsychotic medications like risperidone. Benztropine can help alleviate these acute dystonic reactions. Choice A is incorrect because changing the antipsychotic medication at this point is not indicated. Choice B is not appropriate as the client's symptoms are likely due to acute dystonia rather than muscle spasms. Choice C is also not the best course of action as the client needs immediate intervention for the acute dystonic reaction.
5. A client in a long term care facility complains of pain. The nurse collects data about the client's pain. The first step in pain assessment is for the nurse to
- A. have the client identify coping methods
- B. get the description of the location and intensity of the pain
- C. accept the client's report of pain
- D. determine the client's status of pain
Correct answer: B
Rationale: The correct answer is B: 'get the description of the location and intensity of the pain.' When a client complains of pain, the initial step in pain assessment is to gather information about the location and intensity of the pain. This helps the nurse understand the nature of the pain and lays the groundwork for further assessment and management. Choice A is incorrect because identifying coping methods comes later in the assessment process. Choice C is incorrect as accepting the client's report of pain is important, but not the first step. Choice D is incorrect as determining the client's pain status also comes after gathering information about the pain.
