ATI RN Comprehensive Exit Exam 2023
1. A nurse is planning care for a client who has pneumonia. Which of the following actions should the nurse take to promote airway clearance?
- A. Perform chest physiotherapy every 4 hours.
- B. Suction the client every 2 hours.
- C. Encourage the client to increase fluid intake.
- D. Administer oxygen via nasal cannula.
Correct answer: C
Rationale: Encouraging the client to increase fluid intake is essential in promoting airway clearance for a client with pneumonia. Increased fluid intake helps thin secretions, making it easier for the client to clear their airways. Chest physiotherapy (Choice A) is more focused on mobilizing secretions and may not be suitable for all clients with pneumonia. Suctioning (Choice B) is indicated for clients who have excessive secretions that they cannot manage effectively themselves. Administering oxygen via nasal cannula (Choice D) is important for clients with pneumonia to maintain adequate oxygenation, but it does not directly promote airway clearance.
2. When educating a client about to undergo a pacemaker insertion, the nurse explains the normal phases of cardiac muscle tissue. During the repolarization phase, the nurse will stress that membranes must be repolarized before they can be re-excited. Within the cell, the nurse understands that:
- A. Potassium channels open while sodium channels close, causing repolarization to the resting state.
- B. The influx of calcium is the primary stimulus for the repolarization of cardiac tissue.
- C. Only the electrical activity within the heart will determine when repolarization occurs.
- D. The cell membranes need to stay calm, resulting in muscle tissue becoming refractory.
Correct answer: A
Rationale: During the repolarization phase of cardiac muscle tissue, potassium channels open while sodium channels close. This process is crucial for the cardiac muscle to return to its resting state after depolarization. Potassium moving out of the cell and sodium staying out helps reset the membrane potential and prepare the cell for the next depolarization phase. The influx of calcium is not the primary stimulus for repolarization in cardiac tissue; it is mainly involved in the depolarization phase. While electrical activity within the heart influences repolarization, the specific ion movements described in choice A are what physiologically drive repolarization. Cell membranes need to be in an active state during repolarization, not calm, to facilitate the necessary ion movements for muscle tissue to properly function.
3. Which of the following steps occurs first during hemostasis?
- A. Vascular spasm
- B. Platelet plug
- C. Coagulation
- D. Dissolution of the clot
Correct answer: A
Rationale: Vascular spasm is the initial step in hemostasis, where blood vessels constrict to reduce blood flow to the injured area. This constriction helps limit blood loss until further steps like platelet plug formation and coagulation can take place. Platelet plug formation and coagulation occur after the vascular spasm, making them incorrect choices. Dissolution of the clot happens much later in the healing process, after the injury has sufficiently healed.
4. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?
- A. Strained fruits
- B. Pureed meats
- C. Cooked egg whites
- D. Iron-fortified cereal
Correct answer: Iron-fortified cereal
Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.
5. What is the main purpose of conducting a SWOT analysis in healthcare?
- A. Identify strengths and weaknesses
- B. Develop strategic goals
- C. Assess external opportunities
- D. Streamline healthcare processes
Correct answer: C
Rationale: The main purpose of conducting a SWOT analysis in healthcare is to assess external opportunities along with identifying strengths, weaknesses, and threats. While identifying strengths and weaknesses is a part of the analysis, the primary goal is to evaluate external opportunities and threats to develop strategic goals. Option A is incorrect as the analysis encompasses more than just strengths and weaknesses. Option B is incorrect as developing strategic goals is a result of the analysis, not the main purpose. Option D is incorrect as streamlining healthcare processes is not the primary focus of a SWOT analysis.
