Question 1 of 5
What type of assessment occurs in emergency situations?
Correct Answer: D
Rationale: In emergency situations, time is crucial. Emergency assessment is the most appropriate as it focuses on quickly identifying and addressing life-threatening issues. It involves a rapid but systematic evaluation of the patient's airway, breathing, circulation, and disability. Head-to-toe assessment (A) and comprehensive assessment (C) are too time-consuming in emergencies, whereas focused assessment (B) may not cover all critical aspects.
Question 2 of 5
What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?
Correct Answer: B
Rationale: The given ABG values fall within normal ranges, indicating homeostasis. The pH is within the normal range (7.35-7.45), indicating acid-base balance. The PO2 is slightly lower but still within the normal range (80-100 mmHg). PCO2 falls within the normal range (35-45 mmHg), showing effective ventilation. The HCO3 level is also within the normal range (22-26 mEq/L), indicating proper kidney function. Therefore, all values are within normal limits, reflecting a state of homeostasis. Other choices are incorrect as they suggest imbalances in acid-base status, which is not seen with these values.
Question 3 of 5
What do ABG values of pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L indicate?
Correct Answer: B
Rationale: Rationale: 1. pH within normal range (7.35-7.45) indicates homeostasis. 2. PO2 (normal 75-100 mmHg) and PCO2 (normal 35-45 mmHg) are slightly deviated but not clinically significant. 3. HCO3 within normal range (22-26 mEq/L) further supports overall balance. Summary: A: Incorrect - HCO3 level is within normal range, ruling out metabolic alkalosis. C: Incorrect - PCO2 is within normal range, ruling out respiratory acidosis. D: Incorrect - PCO2 is slightly low but not significantly, ruling out respiratory alkalosis. Overall, the ABG values indicate the body is in homeostasis.
Question 4 of 5
Which condition is mammography used to detect?
Correct Answer: B
Rationale: Mammography is used to detect tumors in the breast tissue. It is a screening tool for breast cancer. Tumors can be either benign or malignant. Mammograms help in early detection of abnormalities in breast tissue. Pain, edema, and epilepsy are unrelated to the purpose of mammography. Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder. Therefore, the correct answer is B because mammography is specifically designed to detect tumors in the breast.
Question 5 of 5
Which sign might a nurse observe in a client with a high ammonia level?
Correct Answer: A
Rationale: The correct answer is A: coma. High ammonia levels can lead to hepatic encephalopathy, causing impaired brain function and potentially leading to coma. Edema (B) is typically associated with fluid retention, not high ammonia levels. Hypoxia (C) is a condition of low oxygen levels, not directly related to high ammonia levels. Polyuria (D) is excessive urination, which is not a common sign of high ammonia levels.
