NCLEX RN Exam Preview Answers
1. What is the most important step that healthcare personnel can take to prevent the transmission of microorganisms in the hospital setting?
- A. Wear protective eyewear at all times.
- B. Wear gloves whenever in direct contact with patients.
- C. Wash hands before and after contact with each patient.
- D. Clean the stethoscope with an alcohol swab between patients.
Correct answer: C
Rationale: The most crucial step in preventing the transmission of microorganisms in the hospital setting is proper hand hygiene. Healthcare personnel should wash their hands thoroughly before and after each patient contact to reduce the risk of spreading infections. While cleaning the stethoscope with an alcohol swab between patients is recommended, it is secondary to hand hygiene. Wearing protective eyewear at all times is not necessary for routine patient care unless specifically indicated, and wearing gloves only when in direct contact with patients is important but not as critical as proper handwashing. Therefore, the correct answer is to wash hands before and after contact with each patient.
2. Intermittent fevers are:
- A. fevers which come and go.
- B. fevers which rise and fall but are always considered above the patient's average temperature.
- C. fevers which fluctuate more than three degrees and never return to normal.
- D. None of the above.
Correct answer: A
Rationale: Intermittent fevers are characterized by periods of fever followed by periods of normal body temperature. They alternate between being febrile and afebrile. Continuous fevers show minimal fluctuations over a 24-hour period, while remittent fevers fluctuate significantly but do return to normal body temperature. Choice A is correct as it accurately describes intermittent fevers. Choices B and C are incorrect as they do not fully capture the defining characteristic of intermittent fevers, which involve cyclical episodes of fever and normal temperature. Choice D is incorrect as there is a specific definition for intermittent fevers.
3. A client is preparing to irrigate a colostomy. Which of the following situations is a contraindication for this type of irrigation?
- A. The client has an incontinent ostomy
- B. The client has an irregular bowel routine
- C. The client has diverticulitis
- D. The colostomy bag contains fecal material
Correct answer: C
Rationale: When a client with a colostomy is preparing for irrigation, it is essential to consider contraindications that could pose risks or worsen the client's condition. Diverticulitis is a contraindication for colostomy irrigation because the inflamed diverticula could be further irritated by the flushing action during irrigation, potentially leading to complications. An incontinent ostomy, irregular bowel routine, or presence of fecal material in the colostomy bag are not specific contraindications for irrigation and can be managed through appropriate techniques and interventions.
4. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?
- A. Citrus fruits
- B. Milk
- C. Fish
- D. Potatoes
Correct answer: B
Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.
5. Surgical asepsis is being performed when:
- A. wiping down exam tables with bleach
- B. sterilizing instruments
- C. changing table paper
- D. wearing gloves when performing injections
Correct answer: B
Rationale: Surgical asepsis refers to the process of maintaining a sterile environment to prevent the introduction of pathogens to a patient's body. Sterilizing instruments is a crucial aspect of surgical asepsis as it ensures that the instruments used during procedures are free from microorganisms that could cause infections. Wiping down exam tables with bleach may help in cleaning and disinfecting surfaces but does not pertain directly to maintaining a sterile field. Changing table paper is important for cleanliness and infection control but is not specifically related to surgical asepsis. Wearing gloves when performing injections is important for standard precautions and preventing the spread of infection but does not encompass the concept of surgical asepsis, which focuses on maintaining a sterile field during invasive procedures.
