A nurse is caring for a client who has diarrhea due to shigella. Which of the following precautions should the nurse implement for this client?
- A. Have the client wear a mask when receiving visitors.
- B. Limit the client's time with visitors to no more than 30 minutes per day.
- C. Assign the client to a room with negative-pressure airflow exchange.
- D. Wear a gown when caring for the client.
Correct Answer: B
Rationale: The correct answer is B: Limit the client's time with visitors to no more than 30 minutes per day. This is the correct precaution because shigella is transmitted through fecal-oral route. By limiting the client's time with visitors, the risk of spreading the infection to others is minimized.
Explanation for why other choices are incorrect:
A: Having the client wear a mask when receiving visitors is not necessary for preventing the spread of shigella, as it is not transmitted through the air.
C: Assigning the client to a room with negative-pressure airflow exchange is more suitable for airborne infections, not for shigella which is transmitted through fecal-oral route.
D: While wearing a gown when caring for the client is a good infection control practice, it is not specifically indicated for preventing the spread of shigella through contact with visitors.

What is the main purpose of the NCLEX examination?
- A. Ensure that individuals have passed nursing classes.
- B. Provide assurance that nursing schools are part of the service agency.
- C. Enable potential students to determine the best nursing schools.
- D. Ensure the safety of the public.
Correct Answer: D
Rationale: The main purpose of the NCLEX examination is to ensure the safety of the public. The exam assesses if a candidate has the knowledge and skills necessary to provide safe and effective nursing care. It is designed to protect the public by ensuring that only competent individuals are granted nursing licensure. This is crucial in maintaining high standards of healthcare and safeguarding patients' well-being.
Incorrect answers:
A: Ensuring that individuals have passed nursing classes is not the main purpose of the NCLEX. Passing nursing classes is a prerequisite for taking the exam but not its primary goal.
B: Providing assurance that nursing schools are part of the service agency is not the main purpose of the NCLEX. The exam focuses on individual competency rather than accrediting nursing schools.
C: Enabling potential students to determine the best nursing schools is not the main purpose of the NCLEX. The exam does not rank or rate nursing schools; its primary aim is to evaluate individual readiness for nursing practice.
The nurse manager compares the actual results of the budget with the projected results of the budget. What budgeting process is this?
- A. Variable budgeting
- B. Controlling
- C. Revenue sharing
- D. Incremental budgeting
Correct Answer: B
Rationale: The correct answer is B: Controlling. The nurse manager comparing actual results with projected results is part of the controlling function of budgeting. Controlling involves monitoring performance against the budget to identify any variations and taking corrective actions if necessary. Variable budgeting focuses on adjusting the budget based on different levels of activity, not comparing actual vs. projected results. Revenue sharing pertains to distributing revenues among different entities. Incremental budgeting involves making small adjustments to the previous budget without a thorough review like in controlling. Thus, the comparison of actual vs. projected results aligns with the controlling function of budgeting.
Which of the following are important techniques when giving directions to subordinates? (EXCEPT)
- A. Know the context of the instructions.
- B. Use lateral communication.
- C. Verify feedback.
- D. Get positive attention.
Correct Answer: B
Rationale: The correct answer is B: Use lateral communication. This is not an important technique when giving directions to subordinates because lateral communication typically involves communication between peers or individuals at the same hierarchical level. When giving directions to subordinates, it is crucial to maintain clear communication channels between superiors and subordinates to ensure clarity and accountability.
A: Knowing the context of the instructions is important to provide relevant and meaningful directions.
C: Verifying feedback helps ensure that the subordinates have understood the directions correctly and can address any misunderstandings.
D: Getting positive attention can motivate subordinates to follow directions effectively, but it is not a fundamental technique for giving directions.
A nurse is caring for a client who has an indwelling urinary catheter. Which of the following findings indicates that the catheter requires irrigation?
- A. Urine is positive for ketones
- B. Urine has an unusual odor
- C. Urine specific gravity is 1.035 (normal range: 1.010 to 1.025)
- D. Bladder scan shows 525 mL of urine
Correct Answer: A
Rationale: The correct answer is A because the presence of ketones in the urine may indicate dehydration or infection, which can lead to catheter obstruction. Irrigation may be needed to clear the catheter and prevent further complications. Choices B, C, and D are incorrect because an unusual odor, high specific gravity, and a significant amount of urine in the bladder do not necessarily indicate the need for catheter irrigation.
Which of the following is an example of a primary prevention strategy in public health?
- A. Screening for diabetes
- B. Vaccination programs
- C. Emergency response planning
- D. Chronic disease management
Correct Answer: B
Rationale: The correct answer is B: Vaccination programs. Primary prevention aims to prevent the onset of disease before it occurs. Vaccination programs are a classic example as they protect individuals from contracting infectious diseases, thus preventing the occurrence of the disease in the first place. Screening for diabetes (A) is a form of secondary prevention, aiming to detect the condition early to prevent complications. Emergency response planning (C) focuses on preparedness for disasters rather than preventing diseases. Chronic disease management (D) involves managing existing conditions rather than preventing their occurrence.
