Question 1
Multiple Choice
Which of the following urinalysis findings would you need to report to the physician?
Correct!
Incorrect
The correct answer is: A,D,F
Rationale
Protein: 30 mg/dL, pH: 4.1, and RBCs: 10 per high-power field need to be reported to the physician.
The presence of protein at 30 mg/dL indicates potential kidney damage or dysfunction, while a pH of 4.1 suggests acidosis, both requiring further evaluation. Additionally, RBCs at this level can indicate bleeding or other serious conditions necessitating immediate medical attention.
B: Bacteria: 0 indicates no infection, thus not warranting reporting. A normal count suggests proper urinary function without concern for bacterial presence.
C: WBCs: 3 to 4 per high-power field represents a normal finding and does not indicate inflammation or infection, making it less critical to report.
E: Specific gravity: 1.025 reflects normal hydration status and kidney function, showing no abnormalities that would require immediate physician notification.

Question 2
Multiple Choice
Which of the following preparatory steps would you be likely to perform prior to a barium enema?
Correct!
Incorrect
The correct answer is: C,D,E
Rationale
C: Administer a laxative the day before the test. This step is crucial to ensure the colon is cleared of stool, allowing for optimal visualization during the barium enema procedure.
A: Start an IV line the day prior to the test. This procedure is not necessary for a barium enema, as intravenous access is typically not required for the test itself.
B: Keep the patient NPO 48 hours prior to the test. Maintaining a patient NPO for such an extended period is excessive; a shorter fasting period is sufficient before the barium enema.
D: Place the patient on a clear liquid diet for 24 hours prior to the test. While a clear liquid diet is beneficial, it is not the primary preparatory step when laxatives are administered effectively.
E: Administer an enema the evening before the test. Although this can help in preparation, it is not universally required since laxatives alone are often sufficient for bowel cleansing.

Question 3
Multiple Choice
Which of the following tests would be helpful for evaluating the large intestine?
Correct!
Incorrect
The correct answer is: A,C
Rationale
Colonoscopy and barium enema are both helpful for evaluating the large intestine. Colonoscopy allows direct visualization and potential biopsy of the colon, while barium enema enhances imaging to identify abnormalities.
B: EGD evaluates the upper gastrointestinal tract, specifically the esophagus, stomach, and duodenum, not the large intestine.
D: ECG assesses heart activity, providing no information about the large intestine's condition.
E: Intravenous pyelogram focuses on the urinary system and does not examine the large intestine.
F: Hgb and Hct measure blood levels, lacking specific insight into large intestine health.

Question 4
Regular
Which of the following findings indicate a left shift and bacterial infection in an adult?
Correct!
Incorrect
The correct answer is: A
Rationale
WBC: 13,900/mm'┬│; total neutrophils: 76% (bands: 30%, segmented: 46%); eosinophils: 2.5%; basophils: 0.5%; monocytes: 4%; lymphocytes: 17%. A left shift indicates increased immature neutrophils (bands), suggesting a recent bacterial infection. The elevated WBC count alongside high neutrophil percentage further supports an active immune response to a bacterial pathogen in the adult.
B: WBC: 4,600/mm'┬│; total neutrophils: 59% (bands: 3%, segmented: 56%); eosinophils: 4%; basophils: 1%; monocytes: 6%; lymphocytes: 30%. The low WBC count and minimal bands indicate no significant left shift or acute bacterial infection.
C: WBC: 11,350/mm'┬│; total neutrophils: 55% (bands: 3%, segmented: 52%); eosinophils: 12%; basophils: 2%; monocytes: 8%; lymphocytes: 23%. Although the WBC count is elevated, the low percentage of bands does not signify a left shift indicative of bacterial infection.
D: WBC: 9,450/mm'┬│; total neutrophils: 61% (bands: 5%, segmented: 65%); eosinophils: 4%; basophils: 1%; monocytes: 3%; lymphocytes: 28%. While there is a slight increase in bands, the overall neutrophil count does not reflect a strong left shift or acute bacterial infection.

Question 5
Multiple Choice
Which of the following tests or procedures is (are) beneficial in evaluation of the kidneys?
Correct!
Incorrect
The correct answer is: A,B,D,E,F
Rationale
A, B, D, E, F: All these tests and procedures provide critical insights into kidney function. They assess various aspects, such as urine composition, filtration rates, and overall kidney health, aiding in effective diagnosis and management of renal conditions.
C: Oral glucose tolerance test evaluates glucose metabolism, not kidney function. It specifically assesses insulin response and is not relevant for diagnosing renal issues or evaluating kidney performance.

Question 6
Regular
You are to provide nursing care for a patient who just had a femoral arteriogram. Which of the following actions would take priority?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Assessment of puncture site for bleeding
Prioritizing the assessment of the puncture site is crucial following a femoral arteriogram, as it directly addresses potential complications such as bleeding, hematoma formation, or thrombosis, which can severely impact patient safety.
A: Assessment of vital signs
While vital signs are important, they do not specifically address immediate complications related to the procedure, such as bleeding at the puncture site, which requires urgent attention.
C: Assessment of temperature of lower extremity on the affected side
Temperature assessment is relevant but secondary; it does not provide immediate information about critical complications like active bleeding from the puncture site, which needs prompt evaluation.
D: Keeping the affected leg straight
Maintaining the leg's position is necessary for healing but does not provide direct information about potential complications, making it a lower priority than assessing the puncture site.
E: Assessment of ability to void
This assessment is important but not urgent after a femoral arteriogram. Evaluating bleeding at the puncture site takes precedence for ensuring the patient's immediate safety.
F: Providing PO fluids
Administering fluids is beneficial for recovery, yet it does not address the critical risk of bleeding from the puncture site, making it less of a priority in this situation.

Question 7
Regular
You should measure the abdominal girth and weight of a patient who is about to undergo:
Correct!
Incorrect
The correct answer is: D
Rationale
Measuring the abdominal girth and weight of a patient is essential prior to a paracentesis. This procedure involves the removal of fluid from the abdominal cavity, making it crucial to assess the patient's baseline metrics for safety and effectiveness.
A: a glucose tolerance test. This test primarily evaluates glucose metabolism, requiring blood samples rather than abdominal measurements, thus rendering girth and weight irrelevant in this context.
B: a CT scan of the cerebrum. This imaging procedure focuses on the brain and does not necessitate any abdominal measurements, as it is unrelated to abdominal conditions.
C: an alkaline phosphatase test. This blood test measures enzyme levels and is not influenced by abdominal girth or weight, making such measurements unnecessary before the procedure.
E: a lumbar puncture. Although this procedure involves the spine, it does not require abdominal girth or weight assessment, as its focus is entirely different.

Question 8

When performing a 12-lead ECG, you know that you will apply:
Correct!
Incorrect
The correct answer is: B
Rationale
12 lead wires. A 12-lead ECG utilizes 10 lead wires to capture 12 different views of the heart's electrical activity, providing comprehensive information about cardiac health and function.
A: 12 lead wires. While the term "12 lead" is used, only 10 physical lead wires are applied to achieve this comprehensive view.
C: 6 lead wires. This number does not encompass the full range of views necessary for a complete 12-lead ECG, limiting diagnostic capabilities.
D: 4 lead wires. Utilizing only four leads significantly restricts the information gathered, failing to provide adequate heart activity assessment for proper diagnosis.
