Question 1 of 5
The factor that most determines drug distribution is:
Correct Answer: A
Rationale: Drugs are distributed via the circulatory system. Adequate perfusion is necessary for distribution of a drug. The other choices are not as dependent on adequate perfusion.
Question 2 of 5
An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?
Correct Answer: A
Rationale: Glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes, enhancing adherence to surfaces, resisting phagocytic engulfment, and preventing antibiotics from contacting the microbe.
Question 3 of 5
For a client with suspected appendicitis, the nurse should expect to find abdominal tenderness in which quadrant?
Correct Answer: C
Rationale: The nurse should expect to find abdominal tenderness in the lower-right quadrant in a client with appendicitis.
Question 4 of 5
Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?
Correct Answer: C
Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions.
Question 5 of 5
Why must the nurse be careful not to cut through or disrupt any tears, holes, bloodstains, or dirt present on the clothing of a client who has experienced trauma?
Correct Answer: C
Rationale: Trauma in any client, living or dead, has potential legal and/or forensic implications. Clothing, patterns of stains, and debris are sources of potential evidence and must be preserved. Nurses must be aware of state and local regulations that require mandatory reporting of cases of suspected child and elder abuse, accidental death, and suicide. Each Emergency Department has written policies and procedures to assist nurses and other health care providers in making appropriate reports. Physical evidence is real, tangible, or latent matter that can be visualized, measured, or analyzed. Emergency Department nurses can be called on to collect evidence. Health care facilities have policies governing the collection of forensic evidence. The chain of evidence custody must be followed to ensure the integrity and credibility of the evidence. The chain of evidence custody is the pathway that evidence follows from the time it is collected until is has served its purpose in the legal investigation of an incident.
