The nurse is assisting in planning care for a client scheduled for insertion of a tracheostomy. Which equipment should the nurse plan to have at the bedside when the client returns from surgery?

Correct Answer: A

Rationale: Post-tracheostomy, the obturator (A) is essential at the bedside to reinsert the tube if dislodged, ensuring airway patency. An oral airway (B) is irrelevant for tracheostomy patients. Epinephrine (C) treats allergic reactions, not routine needs. A larger tracheostomy tube (D) isn't standard emergency equipment. A is correct. Rationale: The obturator facilitates immediate tube replacement, critical in the first 72 hours before a tract forms, preventing airway loss, a priority per surgical nursing standards over other less relevant items.

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.

Correct Answer: B

Rationale: Virginia Henderson's 1966 definition identifies 14 fundamental needs that nursing addresses to help clients achieve independence or a peaceful death. These include breathing, eating, elimination, and rest, among others, forming a comprehensive framework for holistic care. Unlike narrower or broader counts, 14 captures the essentials Henderson deemed universal, guiding nurses to assess and support each area. For example, assisting a client with mobility meets one need, while ensuring nutrition meets another, illustrating practical application. This specificity distinguishes her model, balancing detail with practicality in nursing practice.

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.
