A nurse is caring for a patient who has been declared brain dead and is awaiting organ donation.
Which of the following interventions is most important to preserve the viability of the organs?
Administering antibiotics to prevent infection.
Maintaining normal body temperature and blood pressure.
Providing emotional support to the family members.
Applying eye drops and ointment to prevent corneal drying.
The Correct Answer is B
Early identification and management of potential organ donors must take into consideration specific pathophysiologic changes for medical optimization 1.
The VIPPS (ventilation, infusion and pumping, pharmacological treatment, and specificities) strategy is a mnemonic method that brings together key aspects of the restoration of oxygen delivery to tissues during hemodynamic instability plus organ optimization strategies.
Choice A is incorrect because administering antibiotics to prevent infection is not the most important intervention to preserve organ viability.
Choice C is incorrect because providing emotional support to family members, while important, is not an intervention that directly affects organ viability.
Choice D is incorrect because applying eye drops and ointment to prevent corneal drying is not the most important intervention to preserve organ viability.

Correct Answer is A
Explanation
In a well-designed experiment, all variables apart from the treatment should be kept constant between the control group and treatment group.
This means researchers can correctly measure the entire effect of the treatment without interference from confounding variables.
Choice B) Independent variable and dependent variable is incorrect because these are not groups but rather variables.
The independent variable is manipulated by the experimenters while the dependent variable is measured to see if it changes as a result of the manipulation.
Choice C) Experimental group and non-experimental group is incorrect because a non-experimental group is not a term used in experimental design.
The correct term for the group that does not receive the treatment is control group.
Choice D) High level and low level of the independent variable is incorrect because these are levels of the independent variable, not groups.
In an experiment, there can be multiple levels of the independent variable, but they are applied to different groups (e.g. control group, treatment group).
Correct Answer is A
Explanation
The normal flora refers to the microbial community that colonizes on the skin and mucus membrane.
Normal flora can be found in many human body sites, including the skin, respiratory tract, urinary tract, and digestive tract.
Choice B is incorrect because normal flora does not refer to a group of infectious parasites that cause diarrheal diseases.
Choice C is incorrect because normal flora does not refer to the genetic material of bacteria housed within a true nucleus.
Choice D is incorrect because normal flora does not refer to the protein coat surrounding the viral genome.
