Nclex Exam Cram Practice Questions
1. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:
- A. a vector.
- B. a source, like contaminated water.
- C. food.
- D. the respiratory system.
Correct answer: D
Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.
2. A client is having a seizure; his blood oxygen saturation drops from 92% to 82%. What should the nurse do first?
- A. Open the airway.
- B. Administer oxygen.
- C. Suction the client.
- D. Check for breathing.
Correct answer: A
Rationale: When a client is having a seizure and their blood oxygen saturation drops significantly, the priority action for the nurse is to open the airway. This allows for adequate oxygenation and ventilation. Administering oxygen can come after ensuring the airway is clear. Suctioning the client should be done if there is an airway obstruction, and checking for breathing is part of the assessment but opening the airway takes precedence to ensure proper oxygenation and ventilation during a critical event like a seizure.
3. When assessing a client's mobility status, the physical examination should start with:
- A. examining their gait.
- B. orienting to time, place, and person.
- C. performing the Romberg test.
- D. conducting the Tandem Walk test.
Correct answer: A
Rationale: When assessing a client's mobility status, it is crucial to start by examining their gait. Gait assessment is usually conducted as the client walks into the room. Normal gait is described as smooth, flowing, and rhythmic without the need for assistive devices. Choices B, C, and D are incorrect as they do not represent the standard practice of beginning the assessment of mobility status with gait examination.
4. When the healthcare provider is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should they measure?
- A. corner of the mouth to the tragus of the ear
- B. corner of the eye to the top of the ear
- C. tip of the chin to the sternum
- D. tip of the nose to the earlobe
Correct answer: A
Rationale: When selecting the correct size of an oropharyngeal airway, the healthcare provider should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to maintain a clear air passage for exchange. Measuring from the corner of the eye to the top of the ear (Choice B) is inaccurate and not a standard measurement for selecting the size of an oropharyngeal airway. Measuring from the tip of the chin to the sternum (Choice C) is irrelevant to determining the correct size of the airway. Similarly, measuring from the tip of the nose to the earlobe (Choice D) is also incorrect and does not provide the necessary measurement for selecting an oropharyngeal airway size.
5. Who is responsible for obtaining the signature from the client on the informed consent?
- A. the staff nurse
- B. the charge nurse
- C. the LPN
- D. the physician
Correct answer: D
Rationale: The correct answer is the physician. It is the physician's responsibility to ensure that the client provides informed consent by obtaining their signature. While nurses play a crucial role in the healthcare team, their responsibility lies in verifying that the consent process has been completed correctly and advocating for the client. The staff nurse, charge nurse, and LPN do not have the authority to obtain the client's signature on the informed consent form, as this is within the scope of practice of the physician.
