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. Which statement best describes evidence-based practice?
- A. Reading and analyzing research reports to determine their implementation in nursing practice
- B. Collecting data to evaluate the efficiency of nursing practice in delivering quality care
- C. Monitoring unit practices to ensure adherence to Joint Commission standards
- D. Using the most effective, current, and applicable information to guide nursing care for the best outcomes
Correct answer: D
Rationale: Evidence-based practice involves utilizing the most effective, current, and relevant information to inform nursing care decisions for optimal client outcomes. While research reports and data collection are important components of evidence-based practice, the essence lies in integrating all available information to determine the best course of action. Monitoring compliance with standards, as described in choices A and C, is essential for quality assurance but does not capture the comprehensive nature of evidence-based practice.
3. Which technique is correct when assessing the radial pulse of a patient?
- A. Palpate for 1 minute if the rhythm is irregular.
- B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
- C. Palpate for 2 full minutes to detect any variation in amplitude.
- D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.
Correct answer: A
Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.
4. While auscultating heart sounds, the nurse hears a murmur. Which of these instruments would be used to assess this murmur?
- A. Electrocardiogram
- B. Bell of the stethoscope
- C. Diaphragm of the stethoscope
- D. Palpation with the nurse's palm of the hand
Correct answer: B
Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.
5. In which of the following ways can a nurse promote sleep for a client experiencing insomnia?
- A. Assist the client in using the bathroom one hour after going to bed
- B. Give the client a massage before bedtime
- C. Tuck bed sheets and blankets tightly around the client once settled in bed
- D. Give the client a pair of socks to wear if their feet become cold
Correct answer: D
Rationale: A nurse can promote sleep for a client experiencing insomnia by addressing factors that may hinder sleep. Cold feet can disrupt sleep, so providing the client with socks to keep their feet warm can enhance comfort and aid in promoting sleep. The correct answer focuses on a direct intervention to address a specific issue that can impact sleep quality. Choices A, B, and C do not directly address the issue of cold feet, which is a common problem that can interfere with sleep in individuals with insomnia. Assisting the client to use the bathroom, giving a massage in the morning, or tucking in bed sheets tightly do not target the discomfort caused by cold feet, making them less effective interventions for promoting sleep in this scenario.
