The labor and delivery record is the best place to locate information on the menstrual history, number of pregnancies, and number of living children for each OB patient. This record contains detailed information about the patient's labor and delivery experience, including any complications or interventions that occurred during childbirth. It would also typically include information on the patient's obstetrical history, such as the number of pregnancies and living children. Therefore, this record would provide the most comprehensive and accurate information for the quality improvement study.

63. All of the following may precipitate a seizure EXCEPT:   

Explanation

Severe acidosis is not typically known to precipitate a seizure. Acidosis refers to an abnormal increase in acidity in the blood, which can be caused by various factors such as kidney disease or uncontrolled diabetes. While acidosis can have neurological effects, it is not commonly associated with seizures. On the other hand, hypoglycemia (low blood sugar), brain abscess, and high fever in young children are all known to be potential triggers for seizures.

64. Harry H. Potter was admitted to your hospital to receive the second round of chemotherapy for an invasive tumor. Four days after admission, Harry complained of a sore throat and developed a fever. Harry's throat culture was positive for strep. His strep throat will be  

Explanation

Harry's strep throat will be added to the numerator of the hospital's nosocomial infection rate because he developed the infection during his hospital stay. Nosocomial infections are infections that are acquired in a healthcare setting, and since Harry developed the infection while being admitted to the hospital, it is considered a nosocomial infection. Adding it to the numerator of the hospital's nosocomial infection rate reflects that it is an infection acquired within the hospital.

Submit
65. At the start of January 2013, the bed count in a hospital was 345 it was increased to 422 as of January 15th. Given that the Total IPSD for January was 11,333 find the Bed occupancy rate for January.

Explanation

The bed occupancy rate for January can be calculated by dividing the total inpatient service days (IPSD) by the product of the average bed count and the number of days in January. The average bed count can be calculated by taking the average of the bed count at the start and end of the month. The bed count at the start of January was 345 and it increased to 422 by January 15th. Therefore, the average bed count for January is (345 + 422)/2 = 383.5. The number of days in January is 31. Plugging these values into the formula, we get (11,333 / (383.5 * 31)) * 100 = 94.41%.

Submit
66. Incidence of the disease can be defined as the number of:  

Explanation

The correct answer is "both a and b". Incidence of a disease refers to the number of new cases that occur in a given population over a specific time period. It can also be defined as the number of persons exposed to the risk of the disease during that time period. Therefore, both options a and b are correct as they both describe different aspects of the incidence of a disease.

Submit
67. This component of SOAP includes vital signs, measurement such as height, weight, blood pressure as well as laboratory or diagnostic tests.

Explanation

The component of SOAP that includes vital signs, measurements such as height, weight, blood pressure, and laboratory or diagnostic tests is the Objective section. This section focuses on the objective data collected during the patient's examination, providing measurable and observable information about the patient's condition.

Submit
68. Ln order to derive the total inpatient service days for any given day, you would need to

Explanation

To calculate the total inpatient service days for a given day, you would need to add the number of same-day admits and discharges to the inpatient census. This is because same-day admits and discharges contribute to the overall number of patients in the hospital on that day, which is represented by the inpatient census. By adding these numbers, you can accurately determine the total inpatient service days for that specific day.

70. Which of the following is described as "the ability to appropriately transmit formatted data from one system to another"? 

Explanation

Syntactic interoperability is described as the ability to appropriately transmit formatted data from one system to another. This means that the systems can understand and interpret the data in the same way, even if they may have different underlying structures or technologies. It focuses on the correct syntax and structure of the data being transmitted, ensuring that it can be accurately processed and interpreted by the receiving system.

Submit
71. Coders must assign this procedure on the basis of the title of the report and not on the structures that were viewed or by the findings listed on the report.

Explanation

The correct answer is CT scan of head because the instruction states that coders should assign the procedure based on the title of the report, not the structures viewed or the findings listed. Therefore, even though the other procedures listed may be related to the head or abdomen, the specific instruction given indicates that the CT scan of head is the correct procedure to assign.

Submit
72. What is the effect of an enlarging brain abscess on cardiovascular activity?

Explanation

An enlarging brain abscess can lead to increased pressure within the skull, which can cause compression of the blood vessels. This compression can result in systemic vasoconstriction, where the blood vessels narrow, leading to a decrease in blood flow throughout the body. Additionally, the increased pressure can also affect the cardiac control centers in the brain, leading to a slower heart rate. Therefore, the correct answer is systemic vasoconstriction and slower heart rate.

Submit
73. Clinical Document Architecture (CDA)is an HL7 V3 standard focused on:

Explanation

The correct answer is "organization of data and information for easier communication purposes." This is because Clinical Document Architecture (CDA) is a standard developed by HL7 V3 that focuses on organizing data and information in a structured format, making it easier to exchange and communicate between different healthcare systems. CDA provides a framework for the consistent representation of clinical documents, such as discharge summaries or progress notes, ensuring that the information is organized in a standardized manner for improved interoperability and communication.

74. In 2002, The Kirby Senate Committee report helped shift the focus in health care towards the promise of an integrated health information systems. As a result, core investments were made in information and communication technologies which significantly improved all of the following except

Explanation

The Kirby Senate Committee report in 2002 played a crucial role in redirecting the attention in healthcare towards integrated health information systems. This led to substantial investments in information and communication technologies, which brought about significant improvements in quality, safety, and accessibility of healthcare services. However, the report did not specifically address or prioritize the enhancement of confidentiality in health information systems. Therefore, while the other aspects were positively impacted, confidentiality was not directly improved as a result of the report.

Submit
75. In preparation for an upcoming site visit by Accreditation Canada, you discover that the number of delinquent records for the preceding month exceeded 50% of discharged patients. Even more planning was the pattern you noticed in the type of delinquencies. Which of the following represents the most serious pattern of delinquencies? Fifteen percent of delinquent records show 

Explanation

The most serious pattern of delinquencies is the "missing operative reports" because it is crucial for patient safety and continuity of care. Operative reports provide detailed information about surgical procedures, including the surgeon's findings, techniques used, and any complications or adverse events. Without these reports, it becomes difficult for healthcare providers to make informed decisions regarding follow-up care, potential complications, or future surgeries. This could lead to serious medical errors or delays in treatment.

Submit
76. Which of the following would NOT be addressed in the maintenance phase of the system development lifecycle

Explanation

In the maintenance phase of the system development lifecycle, the focus is on fixing bugs, making updates, and ensuring the system functions properly. The increased volume of data, images, and videos would be addressed in this phase as it may require optimizing storage and processing capabilities. The application version being obsolete would also be addressed in this phase by updating it to the latest version. Similarly, if the application does not meet the needs of the end user, it would be addressed during maintenance by making necessary adjustments. However, ease of use, training, performance, and communication are aspects that are typically addressed during the earlier phases of the lifecycle, such as the design and implementation phases.

77. Seventy-five-year-old Beatrice had been a pack-a-day smoker all of her adult life. Over the previous 3 months she noticed a persistent cough, weight loss, blood in her sputum __________________ and dyspnea. A chest CT scan revealed a mass. Biopsy confirmed the diagnosis of ______________________, which is a type of _____________________ lung cancer. 

Explanation

The correct answer is "hemoptysis, non–small cell, adenocarcinoma." Hemoptysis refers to coughing up blood, which is a symptom that Beatrice experienced. Non-small cell lung cancer is a type of lung cancer that is more common than small cell lung cancer. Adenocarcinoma is a specific type of non-small cell lung cancer that develops in the cells that line the air sacs in the lungs. This explanation aligns with the information given in the passage.

Submit
78. Which of the following is an example of cybernetics? 

Explanation

Cybernetics is the study of communication and control in living organisms and machines. It focuses on how systems can regulate and adapt themselves through feedback mechanisms. Feedback control is an example of cybernetics because it involves using information from the system's output to adjust and regulate its input or behavior. This process of continuous monitoring and adjustment is a fundamental concept in cybernetics and is applied in various fields such as engineering, biology, and psychology.

Submit
79. In the role of a Health Information Management coding supervisor, you are asked to compare the current retrospective coding process with the proposed concurrent coding process. Which visual tool would best identify the pros and cons of each process?

Explanation

Force Field analysis is the best visual tool to identify the pros and cons of each process. This tool helps in analyzing the driving forces (pros) and restraining forces (cons) that affect a particular situation or decision. By using this tool, the coding supervisor can identify the factors that support or hinder the implementation of the current retrospective coding process and the proposed concurrent coding process. This analysis will provide a comprehensive understanding of the advantages and disadvantages of each process, enabling the supervisor to make an informed decision.

Submit
80. If a constant is added to all measurements within a sample:

Explanation

When a constant is added to all measurements within a sample, it does not affect the mean because the constant is added to each individual measurement, thus shifting the entire distribution without changing its center. However, the standard deviation, which measures the spread or dispersion of the data, remains the same because adding a constant to each measurement does not change the relative distances between the data points. Therefore, both statements A and B are false, and the correct answer is that the standard deviation remains the same.

Submit
81. Which one of the following is true concerning the lub-dub sound of the heart:

Explanation

The first sound of the heart, known as "lub," is longer and louder because it is caused by the closure of the AV valves. These valves, including the tricuspid and mitral valves, prevent blood from flowing back into the atria when the ventricles contract. The second sound, known as "dub," is shorter and sharper because it is caused by the closure of the semilunar valves. These valves, including the aortic and pulmonary valves, prevent blood from flowing back into the ventricles when they relax.

Submit
82. You are planning a prospective study to try to prove a cause and effect relationship between dipping snuff and throat cancer. First, you identify subjects who regularly dip snuff and who are free of any signs of throat cancer. Next, you need to identify subjects who  

Explanation

To prove a cause and effect relationship between dipping snuff and throat cancer, it is necessary to compare two groups: one that regularly dips snuff and has throat cancer, and another that does not dip snuff and is free of any signs of throat cancer. By comparing these two groups, any differences in the prevalence of throat cancer can be attributed to the use of snuff. This control group helps to establish a baseline and eliminate confounding factors that could affect the results.

Submit
83. Mary has diabetes. Her physician has told her about some factors that put her more at risk for infections. Which of the following factors would probably NOT be applicable?

Explanation

Increased blood supply would probably NOT be applicable as a factor that puts Mary more at risk for infections. While hypoxia (low oxygen levels) and increased glucose in body fluids can both weaken the immune system and make it harder for the body to fight off infections, increased blood supply would actually enhance the immune response by delivering more oxygen and nutrients to the affected area. Therefore, it would not increase the risk of infections for Mary.

Submit
84. When a procedure is performed because of a problem or complication of an ileostomy or colostomy the coders would look for an ICD 10 CA listed as a:

Explanation

In this case, the correct answer is "malfunction." When a procedure is performed due to a problem or complication of an ileostomy or colostomy, coders would search for an ICD 10 CA code that indicates a malfunction. This suggests that there is an issue with the functioning of the ileostomy or colostomy, which requires medical intervention or treatment. The other options listed (ileostomy, complication, misadventure) are not specifically related to a malfunction and may not accurately describe the reason for the procedure.

Submit
85. This quality analysis process include ensuring that all documentation or entries within that record belong to that particular person and that all required fields and documents are completed including all required authentications.

Explanation

The given explanation suggests that the quality analysis process mentioned involves ensuring that all documentation or entries within a record belong to a specific person and that all necessary fields and documents are completed, including authentications. This process is known as quantitative analysis.

Submit
86. All of the following items mean the same thing, EXCEPT

Explanation

"Inpatient service day," "daily inpatient census," and "daily census" are terms that generally refer to the count of patients receiving inpatient care within a 24-hour period. "Inpatient census," however, is a broader term that may refer to the total number of inpatients present at a specific time rather than the daily count of services provided. Therefore, "inpatient census" doesn't mean exactly the same as the other terms.

Submit
87. Studies designed to be internally valid:

Explanation

The correct answer is "show a cause-effect relationship in the sample or population studied." This answer is correct because studies that are internally valid are able to establish a cause-effect relationship within the specific sample or population that was studied. This means that the study has controlled for potential confounding variables and can confidently attribute any observed effects to the specific variables being studied. However, it does not necessarily mean that the findings can be generalized to a broader population or that the inferences or conclusions drawn from the study are unbiased.
