A nurse who serves on an infection control committee is assessing the adequacy of environmental controls against infection.
What does the nurse know to be the first line of defense in medical asepsis?
Isolation or barrier procedures.
Standard precautions.
Hand hygiene techniques.
Routine cleaning of client rooms.
The Correct Answer is C
Hand hygiene techniques are the first line of defense in medical asepsis because they prevent the transmission of microorganisms from one person or object to another. Hand hygiene techniques include washing hands with soap and water or using an alcohol-based handrub.
Choice A is wrong because isolation or barrier procedures are not the first line of defense in medical asepsis, but rather a way of preventing the spread of infection to other patients or health care workers when a patient has a known or suspected infection.
Choice b is wrong because the nature of detergent used on the unit is not the first line of defense in medical asepsis, but rather a factor that affects the effectiveness of cleaning and disinfection of surfaces and equipment.
Choice D is wrong because the ventilation system type is not the first line of defense in medical asepsis, but rather a factor that affects the quality of air and the risk of airborne transmission of microorganisms.

Explanation
Ineffective protection related to chemotherapy side effects. This nursing diagnosis takes priority for a client who is receiving chemotherapy
treatment for cancer because chemotherapy can cause immunosuppression and increase the risk of infection, bleeding, and other complications.
According to the NANDA-I taxonomy, ineffective protection is defined as “decreased ability of an individual to guard the self from internal or external threats such as illness or injury” (NANDA International, 2018).
Choice A is wrong because situational low self-esteem related to job loss due to chemotherapy side effects is not a priority diagnosis for a client who is receiving chemotherapy treatment for cancer. Although chemotherapy can affect the client’s self-image and emotional well-being, it is not a life-threatening condition and can be addressed after ensuring the client’s safety and physiological needs.
Choice C is wrong because anticipatory grieving related to a cancer diagnosis is not a priority diagnosis for a client who is receiving chemotherapy treatment for cancer. Although cancer can cause emotional distress and grief for the client and their family, it is not an immediate threat to the client’s health and can be managed with psychological support and counseling.
Choice D is wrong because fatigue related to cancer treatments is not a priority diagnosis for a client who is receiving chemotherapy treatment for cancer. Although chemotherapy can cause fatigue and weakness, it is not a critical condition and can be alleviated with rest, nutrition, and energy conservation strategies.
Correct Answer is D
Explanation

Choice A is wrong because hs stands for hora somni, which means at bedtime in Latin. This abbreviation indicates that a medication is to be administered before the patient goes to sleep.
Choice B is wrong because prn stands for pro re nata, which means as needed in Latin. This abbreviation indicates that a medication is to be administered only when the patient requires it.
Choice C is wrong because ac stands for ante cibum, which means before meals in Latin. This abbreviation indicates that a medication is to be administered before the patient eats.
