NCLEX RN Predictor Exam
1. For a healthcare worker under normal conditions with unsoiled hands, effective hand hygiene between patients requires which of the following?
- A. At least a 15-second scrub with plain soap and water
- B. At least a 23-minute scrub with an antimicrobial soap
- C. Use of an alcohol-based antiseptic hand-rub
- D. Wearing a mask when scrubbing
Correct answer: C
Rationale: Effective hand hygiene between patients for a healthcare worker with unsoiled hands involves using an alcohol-based antiseptic hand rub. This method is sufficient for cleaning hands that are not visibly soiled. The use of an antimicrobial soap or a prolonged scrubbing time is unnecessary and not recommended in this scenario. Wearing a mask is not required for routine hand hygiene and does not contribute to effective hand cleaning.
2. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?
- A. Exercise
- B. Radiation
- C. Metabolism
- D. Food digestion
Correct answer: B
Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.
3. When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?
- A. Asian
- B. Hispanic
- C. American Indian
- D. African American/Black
Correct answer: B
Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.
4. A student is late for an appointment and has rushed across campus to the health clinic. How should the nurse proceed?
- A. Allow 5 minutes for the student to relax and rest before checking their vital signs.
- B. Check the blood pressure in both arms, expecting a difference in the readings due to the recent exercise.
- C. Immediately monitor the student's vital signs upon arrival at the clinic and then 5 minutes later, recording any differences.
- D. Check the student's blood pressure in the supine position to provide a more accurate reading and allow the student to relax at the same time.
Correct answer: A
Rationale: To ensure an accurate blood pressure reading, it is important for the student to be in a relaxed state. Allowing at least a 5-minute rest period helps reduce anxiety and provides a valid blood pressure measurement. Checking the blood pressure in both arms is unnecessary unless there is a specific reason to suspect an issue, and recent exercise should not significantly impact the readings. Monitoring vital signs immediately upon arrival may not yield accurate results due to the rush and anxiety of the student. Checking blood pressure in the supine position is not necessary in this scenario and does not provide a more accurate reading.
5. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?
- A. Standard Precautions apply to all body fluids, except sweat.
- B. Alcohol-based hand rub should be used if hands are not visibly dirty.
- C. Standard Precautions are intended for use with all patients, regardless of their risk or presumed infection status.
- D. Standard Precautions are to be used only when non-intact skin, excretions containing visible blood, or expected contact with mucous membranes are present.
Correct answer: C
Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat - whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.
