A nurse is preparing to infuse a 250-mL unit of packed RBCs over 2 hours. The drop factor of the manual IV tubing is 15 gtts/mL. The nurse should adjust the flow rate to deliver how many drops per minute?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["31"]
Step 1: Determine the total volume to be infused.
- Total volume = 250 mL
Step 2: Determine the total time for infusion in minutes.
- Total time = 2 hours
- Convert hours to minutes: 2 hours × 60 minutes/hour = 120 minutes
- Result: 120 minutes
Step 3: Determine the drop factor.
- Drop factor = 15 gtts/mL
Step 4: Calculate the flow rate in drops per minute.
- Flow rate (gtts/min) = (Total volume in mL × Drop factor) ÷ Total time in minutes
- Flow rate (gtts/min) = (250 mL × 15 gtts/mL) ÷ 120 minutes
- Result: (250 × 15) = 3750
- Result: 3750 ÷ 120 = 31.25
Step 5: Round the result to the nearest whole number.
- Rounded result: 31
Final Answer: The nurse should adjust the flow rate to deliver 31 drops per minute.

Correct Answer is C
Explanation
Choice A reason:
The statement that nonverbal communication conveys less truth than what the client states verbally is incorrect. Nonverbal communication often conveys more truth than verbal communication because it includes body language, facial expressions, and other cues that can reveal a person’s true feelings and intentions. People may say one thing but their nonverbal cues can indicate something different.
Choice B reason:
The statement that the client enacts nonverbal communication consciously is not entirely accurate. While some nonverbal behaviors are conscious, many are subconscious and automatic. For example, facial expressions and body posture often occur without conscious thought and can provide genuine insights into a person’s emotions and state of mind.
Choice C reason:
The client’s sociocultural background influences nonverbal communication is correct. Different cultures have varying norms and interpretations for nonverbal behaviors. For instance, eye contact, gestures, and personal space can have different meanings across cultures. Understanding a client’s sociocultural background helps in accurately interpreting their nonverbal cues.
Choice D reason:
The statement that nonverbal communication is a poor reflection of what the client feels is incorrect. Nonverbal communication is often a very accurate reflection of a person’s feelings. It includes subtle cues like tone of voice, facial expressions, and body language, which can provide deeper insights into a person’s emotional state than words alone.
Correct Answer is B
Explanation
Choice A reason:
The statement “Treat clients with an antitoxin” is not the primary initial action for anthrax exposure. Antitoxins are used in cases of severe anthrax infection, particularly inhalational anthrax, to neutralize the toxins produced by Bacillus anthracis. However, the first line of treatment for suspected anthrax exposure is antibiotic therapy to eliminate the bacteria.
Choice B reason:
The statement “Administer antibiotic therapy” is correct. The primary treatment for anthrax exposure is the prompt administration of antibiotics. Ciprofloxacin and doxycycline are commonly used antibiotics for treating anthrax. Early antibiotic treatment is crucial to prevent the progression of the disease and reduce the risk of severe complications.
Choice C reason:
The statement “Initiate client decontamination” is not typically necessary for anthrax exposure. Anthrax spores are not easily spread from person to person, and decontamination is generally not required unless there is a significant risk of environmental contamination. The focus should be on administering antibiotics and monitoring the clients for symptoms.
Choice D reason:
The statement “Place the clients in isolation” is incorrect. Anthrax is not contagious and does not spread from person to person. Therefore, isolation is not required for individuals exposed to anthrax. The priority is to provide appropriate medical treatment and monitor for signs of infection.
