A nurse is caring for a client who has an indwelling urinary catheter.
The nurse notes that sediment is present in the urine.
Which of the following actions should the nurse take to obtain a sterile urine specimen?
Unclamp the collection port below the bag.
Obtain the specimen from the retention port.
Disconnect the catheter from the collection tubing.
Use the balloon port to obtain the sterile specimen.
The Correct Answer is B
This is because the retention port is a sterile site that can be accessed by a syringe to aspirate urine without contaminating the specimen or the closed drainage system. The retention port should be cleaned with an alcohol swab before inserting the syringe. The specimen should be transferred to a sterile container and labeled appropriately.
Choice A is wrong because unclamping the collection port below the bag would allow urine to flow out of the bag, which is not sterile and may contain bacteria or sediment.
Choice C is wrong because disconnecting the catheter from the collection tubing would break the closed drainage system and increase the risk of infection.
Choice D is wrong because using the balloon port to obtain the sterile specimen would deflate the balloon that holds the catheter in place and cause trauma to the bladder wall.
Normal ranges for urine characteristics vary depending on the type of analysis, but some general parameters are:
• Color: pale yellow to amber
• Clarity: clear or slightly cloudy
• Odor: faint aromatic
• pH: 4.5 to 8.0
• Specific gravity: 1.005 to 1.030
• Protein: <150 mg/24 hr
• Glucose: negative
• Ketones: negative
• Blood: negative
• Nitrites: negative
• Leukocyte esterase: negative
• Bacteria: <10,000 CFU/mL

Correct Answer is C
Explanation
Administer sublingual nitroglycerin.
Nitroglycerin is a vasodilator that can relieve chest pain caused by myocardial ischemia. The nurse should administer it as soon as possible to improve blood flow to the heart and reduce the risk of myocardial infarction. The nurse should also monitor the client’s blood pressure and heart rate after giving nitroglycerin, as it can cause hypotension and reflex tachycardia.
Choice A is wrong because checking a STAT cardiac troponin is not the first priority.
Cardiac troponin is a biomarker that indicates myocardial injury, but it may not rise until several hours after the onset of chest pain.
Therefore, it is not useful for immediate diagnosis or treatment of acute coronary syndrome. Choice B is wrong because requesting a prescription for a beta-blocker is not the first priority.
Beta-blockers are medications that can lower blood pressure and heart rate, and reduce the oxygen demand of the heart.
They can prevent or reduce the recurrence of chest pain and complications of acute coronary syndrome, but they are not indicated for immediate relief of chest pain.
Choice D is wrong because administering oxygen is not the first priority.
Oxygen therapy can increase the oxygen supply to the heart and reduce ischemia, but it is not necessary for all clients with chest pain.
Oxygen therapy should be based on the client’s oxygen saturation level and clinical condition.
If the client’s oxygen saturation is normal or high, oxygen therapy may not be beneficial and may even be harmful.
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.
