NCLEX RN Exam Preview Answers
1. The nurse is preparing to assess a hospitalized patient who is experiencing significant shortness of breath. How should the nurse proceed with the assessment?
- A. Have the patient lie down to obtain an accurate cardiac, respiratory, and abdominal assessment.
- B. Obtain a thorough history and physical assessment from the patient's family member.
- C. Immediately perform a complete history and physical assessment to obtain baseline information.
- D. Examine the body areas relevant to the problem and complete the rest of the assessment after the problem has resolved.
Correct answer: D
Rationale: When assessing a patient experiencing significant shortness of breath, it is crucial to prioritize the evaluation of areas directly related to the problem. Having the patient lie down may exacerbate the breathing difficulty. Therefore, the nurse should focus on examining the body areas pertinent to the issue, such as the respiratory and cardiac systems. Completing the rest of the assessment can be deferred until after addressing the immediate problem. Obtaining a complete history or involving family members should come after addressing the acute issue to ensure the patient's safety and comfort.
2. What does the medical term 'basophilia' refer to?
- A. An attachment of the epithelial cells of the skin to a basement membrane
- B. An overabundance of a particular white blood cell in the peripheral blood
- C. An underrepresentation of basophils on a blood smear
- D. None of the above
Correct answer: B
Rationale: The correct answer is 'An overabundance of a particular white blood cell in the peripheral blood.' Basophilia specifically indicates an increased number of basophils in the peripheral blood. It can be observed in conditions like leukemia and certain allergic reactions. Choice A is incorrect as it describes something unrelated to basophilia. Choice C is incorrect as it suggests a decrease in basophils, which is opposite to the actual meaning of basophilia. Choice D is also incorrect as basophilia does have a defined medical significance.
3. According to the American Heart Association standards, high-quality CPR for an adult includes all of the following EXCEPT:
- A. Push hard
- B. Push fast
- C. Allow chest recoil between compressions
- D. Pause CPR as each drug is administered
Correct answer: D
Rationale: High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.
4. How many cc are there in 25 ounces?
- A. 250
- B. 500
- C. 750
- D. 1000
Correct answer: C
Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.
5. While measuring a patient's blood pressure, which factor influences a patient's blood pressure?
- A. Pulse rate
- B. Pulse pressure
- C. Vascular output
- D. Peripheral vascular resistance
Correct answer: D
Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.
