A nurse is assessing a client who is experiencing hypovolemia. Which of the following manifestations should the nurse expect?
Epistaxis.
Headache.
Dizziness.
Shortness of breath.
The Correct Answer is C
Dizziness is a manifestation of hypovolemia, which is a decrease in blood volume due to fluid loss. Hypovolemia can cause orthostatic hypotension, which is a drop in blood pressure when changing positions. This can lead to dizziness, lightheadedness, or fainting.
Choice A is wrong because it is not a sign of hypovolemia, but rather a possible cause of it. Epistaxis is a nosebleed that can result from trauma, infection, dryness, or coagulation disorders.
Choice B is wrong because it is not a specific sign of hypovolemia, but rather a nonspecific symptom that can have many causes. Headache can be associated with dehydration, but it can also be caused by stress, infection, inflammation, or other factors.
Choice D is wrong because it is not a sign of hypovolemia, but rather a sign of fluid volume excess.
Fluid volume excess is an increase in blood volume due to fluid retention or overload. Fluid volume excess can cause dyspnea, which is difficulty breathing or shortness of breath.
Normal ranges for blood pressure are 90/60 mm Hg to 120/80 mm Hg for adults. Normal ranges for heart rate are 60 to 100 beats per minute for adults.

Correct Answer is B
Explanation
Previous violent behavior. According to the web search results, this is the best predictor of future violence among the given risk factors.
Other risk factors include past history of aggression, poor impulse control, and violence. Comorbidity that leads to acts of violence (psychotic delusions, command hallucinations, violent angry reactions with cognitive disorders).
Choice A is wrong because a history of being in prison is not a direct cause of violence, but rather a possible consequence of it.
Choice C is wrong because male gender is not a sufficient factor to predict violence, as there are many other variables involved.
Choice D is wrong because experiencing delusions is not necessarily associated with violence unless they are of a paranoid or persecutory nature.
Normal ranges for violence risk assessment are not standardized, but some tools that can be used include the Historical Clinical Risk Management-20 (HCR-20), the Violence Risk Appraisal Guide (VRAG), and the Psychopathy Checklist-Revised (PCL-R). These tools use different scales and criteria to evaluate the likelihood of violent behavior in individuals.
Correct Answer is D
Explanation
A noncoring needle is a special type of needle that has a beveled tip and a side hole. It is designed to prevent damage to the port’s septum, which is the soft silicone top that serves as the vein access point. A noncoring needle also reduces the risk of infection and clotting.
Choice A is wrong because a butterfly needle is a small, winged needle that is used for peripheral venous access, not for accessing a port. A butterfly needle can damage the port’s septum and cause leakage or infection.
Choice B is wrong because an angiocatheter is a thin, plastic tube that is inserted into a vein using a needle.
It is used for short-term IV therapy, not for accessing a port. An angiocatheter can also damage the port’s septum and cause complications.
Choice C is wrong because a 25-gauge needle is too small to access a port.
A 25-gauge needle is typically used for subcutaneous injections, not for intravenous injections. A 25-gauge needle can also clog the port or cause hemolysis (breakdown of red blood cells).
Normal ranges for ports vary depending on the type and size of the port, but generally they have a reservoir diameter of 1.5 to 2.5 cm, a catheter length of 40 to 60 cm, and a catheter diameter of 0.8 to 1.2 mm. Ports are usually flushed with saline or heparin solution every 4 to 6 weeks when not in use to prevent clotting.
