Nokea
Following an automobile accident that caused a head injury to an adult client, the nurse observes that the client sleeps for long periods of time. The nurse determines that the client has experienced injury to the:
- A. hypothalamus.
- B. thalamus.
- C. cortex.
- D. medulla.
Correct Answer: A
Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.

Which of the following lab values is elevated first after a client has a myocardial infarction?
- A. LDH
- B. troponin
- C. CPK
- D. SGOT
Correct Answer: B
Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.
To ensure proper immobilization and increase client comfort when using a rigid splint, what should be done?
- A. Place the client on a stretcher before splinting.
- B. Place the client on a long spine board before splinting.
- C. Pad the spaces between the body part and the splint.
- D. Ensure that the splint conforms to the body curves.
Correct Answer: C
Rationale: Correct. When using a rigid splint, it is essential to pad the spaces between the body part and the splint to ensure proper immobilization and increase client comfort. This padding helps prevent pressure points and ensures a proper fit of the splint without causing discomfort. Placing the client on a stretcher or a long spine board before splinting (choices A and B) may be necessary for transportation but does not directly relate to the proper use of a rigid splint. Ensuring that the splint conforms to the body curves (choice D) is important but not as crucial as padding the spaces to prevent discomfort and ensure proper immobilization.
What is the term for the tendency of a drug to combine with its receptor?
- A. potency
- B. efficacy
- C. kinetics
- D. affinity
Correct Answer: D
Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.
Following abdominal surgery, a client has a nasogastric (NG) tube in place. What is the purpose of this tube immediately after surgery?
- A. simplify medication administration
- B. measure accurate input and output
- C. prevent accumulation of fluids and gas
- D. facilitate collection of specimens
Correct Answer: C
Rationale: The correct answer is to prevent accumulation of fluids and gas. Immediately after abdominal surgery, the NG tube is used to keep the stomach decompressed, preventing the accumulation of fluids and gas. This helps in maintaining decompression to prevent surgical-site disruption and fluid loss through vomiting. Choices A, B, and D are incorrect because the primary purpose of the NG tube following abdominal surgery is to prevent complications related to fluid and gas build-up rather than simplifying medication administration, measuring input and output, or collecting specimens.
The nurse notices that a family is waiting at the nursing station desk for its loved one to be brought to the unit for admission during a change-of-shift report. The nurse should:
- A. request that the family wait for its loved one in the client's room and wait to resume the report until the family has left the desk area.
- B. request that a nursing assistant bring coffee for the family while it waits at the desk and continue with the report.
- C. request that the family have a seat in the station rather than stand while awaiting its loved one.
- D. request that the family wait for its loved one in the Emergency Department waiting room.
Correct Answer: A
Rationale: To protect the privacy of clients and the confidentiality of the information shared in a change-of-shift report, the family should be asked to wait in the client's room. This ensures that sensitive information is not overheard. The report should be resumed only after the family has left the desk area to maintain confidentiality. Choice B is incorrect as bringing coffee does not address the issue of maintaining confidentiality. Choice C is incorrect as standing or sitting in the station does not prevent the family from overhearing confidential information. Choice D is incorrect as the Emergency Department waiting room is not the appropriate setting for waiting during a unit admission.
