NCLEX RN Predictor Exam
1. A urine pregnancy test:
- A. May be negative even if a blood pregnancy test is positive.
- B. Is positive only during the first trimester of pregnancy.
- C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
- D. All of the above.
Correct answer: A
Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.
2. 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.
3. What term is used to refer to generalized wasting of body tissues and malnutrition?
- A. Entropion
- B. Confabulation
- C. Induration
- D. Cachexia
Correct answer: D
Rationale: Cachexia is the correct term used to describe the generalized wasting of body tissues, ill health, and malnutrition associated with some chronic diseases. It involves a loss of fat tissue to protect the bones and joints. Clients with cachexia are at risk of pressure ulcers and other complications due to malnutrition and poor health. Entropion refers to an eyelid condition, confabulation is a memory disturbance, and induration is the abnormal hardening of a part of the body.
4. On admission to the psychiatric unit, the client is trembling and appears fearful. The nurse's initial response should be to:
- A. Give the client orientation materials and review the unit rules and regulations.
- B. Introduce him/her and accompany the client to the client's room.
- C. Take the client to the day room and introduce him/her to the other clients.
- D. Ask the nursing assistant to get the client's vital signs and complete the admission search.
Correct answer: B
Rationale: Anxiety is triggered by change that threatens the individual's sense of security. In response to anxiety in clients, the nurse should remain calm, minimize stimuli, and move the client to a calmer, more secure/safe setting. The correct initial response is to introduce the client and accompany them to their room. This approach helps the client feel oriented, safe, and supported. Giving orientation materials or reviewing rules and regulations may overwhelm the client further. Taking the client to the day room and introducing them to other clients could increase anxiety by exposing them to unfamiliar faces. Asking the nursing assistant to get vital signs and complete admission tasks can wait until the client feels more settled and secure in their environment.
5. The mitral valve is synonymous with the term:
- A. Left ventricle
- B. Right atrium
- C. Bicuspid valve
- D. Tricuspid valve
Correct answer: C
Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.
