Which of the following are antiviral drug classes used in the treatment of HIV/AIDS?
- A. Nucleoside reverse transcriptase inhibitors
- B. Protease inhibitors
- C. HIV fusion inhibitors
- D. All of the above
Correct Answer: D
Rationale: The correct answer is 'All of the above.' Nucleoside reverse transcriptase inhibitors inhibit the enzyme reverse transcriptase, protease inhibitors block the activity of the HIV-1 protease enzyme, and HIV fusion inhibitors prevent HIV from entering human cells. Therefore, all the choices provided are valid antiviral drug classes for managing HIV/AIDS. Nucleoside reverse transcriptase inhibitors, protease inhibitors, and HIV fusion inhibitors play crucial roles in combating the virus at different stages. Nucleoside reverse transcriptase inhibitors target an early stage, protease inhibitors act on a later stage, and HIV fusion inhibitors prevent viral entry. Thus, 'All of the above' is the correct and comprehensive answer encompassing different mechanisms of action in managing HIV/AIDS.

What is the role of the incident report in risk management?
- A. Liability protection.
- B. To provide data for analysis by a risk manager to determine how future problems can be avoided.
- C. To discipline staff for errors.
- D. All of the above.
Correct Answer: B
Rationale: The correct answer is 'To provide data for analysis by a risk manager to determine how future problems can be avoided.' Incident reports are a crucial tool for collecting information about incidents to analyze them and prevent similar issues in the future. They are not primarily used for liability protection or disciplining staff. Therefore, choices A and C are incorrect. Selecting 'All of the above' (choice D) is not accurate as incident reports serve a specific purpose related to data analysis and risk prevention, excluding liability protection and staff discipline.
What is the 24-hour day-night cycle known as?
- A. circadian rhythm
- B. infradian rhythm
- C. ultradian rhythm
- D. non-REM rhythm
Correct Answer: A
Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.
In an emergency situation, the nurse determines whether a client has an airway obstruction. Which of the following does the nurse assess?
- A. ability to speak
- B. ability to hear
- C. oxygen saturation
- D. adventitious breath sounds
Correct Answer: A
Rationale: In an emergency situation to assess for airway obstruction, the nurse should prioritize assessing the client's ability to speak. If a client can speak, it indicates that the airway is patent and not completely obstructed, allowing air to pass through the vocal cords for speech production. Choices B, C, and D are not the primary assessments for determining airway obstruction. Assessing the ability to hear is not directly related to an airway obstruction. While oxygen saturation and adventitious breath sounds are important in respiratory assessments, they are not the initial indicators of an airway obstruction. Oxygen saturation reflects the amount of oxygen in the blood, and adventitious breath sounds refer to abnormal lung sounds that may indicate conditions like pneumonia or bronchitis, but they do not specifically confirm airway patency.
After delivery, a newborn undergoes an Apgar assessment. What does this scoring system evaluate?
- A. heart rate, respiratory effort, color, muscle tone, reflex irritability
- B. heart rate, bleeding, cyanosis, edema
- C. bleeding, reflex, edema
- D. respiratory effort, heart rate, seizures
Correct Answer: B
Rationale: The Apgar scoring system, developed by Virginia Apgar, an anesthesiologist, evaluates newborns based on five criteria: heart rate, respiratory effort, color, muscle tone, and reflex irritability. These parameters provide a quick and simple assessment of a newborn's overall condition and the need for immediate medical attention. Choices B, C, and D are incorrect as they do not encompass the essential elements evaluated by the Apgar scoring system.
Quality is defined as a combination of all of the following except:
- A. conforming to standards.
- B. performing at the minimally acceptable level.
- C. meeting or exceeding customer requirements.
- D. exceeding customer expectations.
Correct Answer: B
Rationale: Quality in any context is about meeting or exceeding customer requirements and exceeding customer expectations. It also involves conforming to standards to ensure consistency and reliability. Merely performing at the minimally acceptable level does not encompass the essence of quality, as it sets the bar at the lowest level of acceptability rather than aiming for excellence or customer satisfaction. Therefore, the correct answer is 'performing at the minimally acceptable level,' as this choice falls short in capturing the comprehensive definition of quality.
