A nurse is providing preoperative teaching to a client about promoting circulation during the postoperative period.
Which of the following instructions should the nurse include?
Participate in range-of-motion exercises
Use an incentive spirometer every 4 hours
Remain on bed rest for 24 hours following the procedure
Place a pillow under your knees while in bed
The Correct Answer is A
This instruction will help the client to prevent venous stasis and thrombosis, which are common postoperative complications. Range-of-motion exercises promote blood circulation and prevent muscle atrophy and contractures.
Choice B. “Use an incentive spirometer every 4 hours.” is wrong because it is not related to promoting circulation, but rather to improving lung expansion and preventing atelectasis and pneumonia. Using an incentive spirometer is also important for postoperative clients, but it does not address the question.
Choice C. “Remain on bed rest for 24 hours following the procedure.” is wrong because it is the opposite of promoting circulation.
Bed rest increases the risk of venous stasis, thrombosis, and pulmonary embolism. Postoperative clients should be encouraged to ambulate as soon as possible, unless contraindicated.
Choice D. “Place a pillow under your knees while in bed.” is wrong because it also impairs circulation and increases the risk of thrombosis.
Placing a pillow under the knees can cause pressure on the popliteal veins and reduce blood flow. Postoperative clients should avoid this position and keep their legs in a neutral or slightly elevated position.

Correct Answer is D
Explanation
Answer:D. Troponin T test
Rationale:
A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.
B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.
C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.
D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.
Correct Answer is B
Explanation
The correct answer is B.
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.
