ATI Fundamentals Proctored Exam 2024
1. What is the primary purpose of a platelet count?
- A. Assessing clot formation potential
- B. Assessing bleeding risk
- C. Detecting antigen-antibody response
- D. Identifying cardiac enzymes presence
Correct answer: B
Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.
2. Which hormone is secreted by the Islets of Langerhans?
- A. Progesterone
- B. Testosterone
- C. Insulin
- D. Hemoglobin
Correct answer: C
Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.
3. A client with vision loss is under the care of a nurse. Which of the following actions should the nurse AVOID?
- A. Keep objects in the client's room in the same place
- B. Ensure there is high-wattage lighting in the client's room
- C. Approach the client from the side
- D. Allow extra time for the client to perform tasks
Correct answer: Approach the client from the side
Rationale: Approaching a client with vision loss from the side can startle them and may lead to accidents or discomfort. It is important to approach them from the front so they are aware of your presence. Keeping objects in the same place aids in familiarity and reduces the risk of falls. High-wattage lighting enhances visibility for the client. Allowing extra time for tasks accommodates the client's potential slower pace and ensures they can perform tasks safely.
4. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:
- A. Infection
- B. Hypothermia
- C. Anxiety
- D. Dehydration
Correct answer: D
Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.
5. The physician orders the administration of high-humidity oxygen by face mask and placement of the patient in a high Fowler’s position. After assessing Mrs. Paul, the nurse writes the following nursing diagnosis: Impaired gas exchange related to increased secretions. Which of the following nursing interventions has the greatest potential for improving this situation?
- A. Encourage the patient to increase her fluid intake to 200 ml every 2 hours
- B. Place a humidifier in the patient’s room
- C. Continue administering oxygen by high humidity face mask
- D. Perform chest physiotherapy on a regular schedule
Correct answer: D
Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.
