A theory is a set of concepts, definitions, relationships and assumptions that:
- A. Explain a phenomenon
- B. Formulate legislation
- C. Measure nursing functions
- D. Reflect the domain of nursing practice
Correct Answer: A
Rationale: A theory in nursing, like Orem's Self-Care Deficit, comprises concepts (e.g., self-care), definitions (clarifying terms), relationships (how concepts interact), and assumptions (underlying beliefs), all to explain phenomena patterns or events like patient recovery. This explanatory role guides practice by providing a lens to understand health-related behaviors or outcomes. Formulating legislation is unrelated; theories inform policy indirectly but aren't legal tools. Measuring nursing functions might be a research outcome, not a theory's purpose, which is broader and conceptual. Reflecting the domain of nursing practice describes what theories encompass but not their active function explanation drives their utility. By explaining phenomena, theories offer nurses frameworks to predict, interpret, and address patient needs, making this the most accurate description of a theory's role in nursing science.
The nurse should recognize that all of the following physical changes of the head and face are associated with the aging client except:
- A. Pronounced wrinkles on the face
- B. Decreased size of the nose and ears
- C. Increased growth of facial hair
- D. Neck wrinkles
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Your assigned client has encephalitis, and there are other cases in the community. In a team meeting regarding your client and prevention of other cases of encephalitis, the nurse supervisor talks about breaking the chain of infection at the second link: the reservoir. You realize the nurse supervisor is talking about which of the following things?
- A. an area for the storage and filtering of water
- B. a place where the microorganism enters the body
- C. the place where the microorganism naturally lives
- D. the microorganism itself
Correct Answer: C
Rationale: Breaking the infection chain at the reservoir means targeting where the microorganism naturally lives like mosquitoes for encephalitis. This differs from the pathogen itself, entry portals, or unrelated water storage. Controlling reservoirs, such as vector elimination, stops transmission early, a vital nursing strategy in outbreak prevention discussed in team settings.
A healthcare provider is planning care for a client who has a pressure ulcer. Which of the following interventions should the healthcare provider include?
- A. Massage the ulcer
- B. Apply a heating pad
- C. Reposition the client every 2 hours
- D. Use alcohol-based cleansers
Correct Answer: C
Rationale: Repositioning the client every 2 hours is a crucial intervention in the management of pressure ulcers. This action helps redistribute pressure, reducing the risk of further skin breakdown and promoting wound healing. Massaging the ulcer can cause further damage to the skin and underlying tissues. Applying a heating pad can increase the risk of skin breakdown and should be avoided. Alcohol-based cleansers are too harsh for pressure ulcers and can irritate the skin, potentially delaying healing.
Outline the process of speciation
- A. Speciation is the splitting of species into two species
- B. Reproductive isolation/lack of interbreeding
- C. Isolation due to geography/reproductive behaviour/reproductive timing
- D. Gene pools separated
Correct Answer: B
Rationale: Speciation involves reproductive isolation (B), preventing gene flow between populations, leading to new species. Splitting (A) is the outcome, not the process. Isolation factors (C) are mechanisms, not the core. Gene pool separation (D) is a result. B is correct. Rationale: Reproductive isolation, via geographic, behavioral, or temporal barriers, is the foundational process of speciation, driving genetic divergence over time, per evolutionary biology. This distinguishes it from outcomes or mechanisms, ensuring species evolve independently, as seen in Darwin's finches or allopatric speciation models.
