Exam Cram NCLEX RN Practice Questions
1. When assessing the force or strength of a pulse, what would the nurse recall about the pulse?
- A. Is a reflection of the heart's stroke volume
- B. Typically recorded on a 0- to 3-point scale
- C. Demonstrates elasticity of the blood vessel wall
- D. Reflects the blood volume in the arteries during diastole
Correct answer: A
Rationale: When assessing the force or strength of a pulse, the nurse should recall that it is a reflection of the heart's stroke volume. The heart pumps an amount of blood (the stroke volume) into the aorta, causing arterial walls to flare and generate a pressure wave felt as the pulse in the periphery. The force of the pulse is typically recorded on a 0- to 3-point scale, not a 0- to 2-point scale. The force of the pulse does not demonstrate the elasticity of blood vessel walls or reflect the blood volume in the arteries during diastole. Therefore, choices B, C, and D are incorrect.
2. The acronym FAST is used to help responders remember the steps to recognizing which of the following conditions?
- A. Onset of labor in a pregnant woman
- B. Stroke
- C. Heart attack
- D. Migraine
Correct answer: B
Rationale: The correct answer is B: Stroke. The acronym FAST is used to help recognize the signs of a stroke. The letters stand for Face, Arms, Speech, and Time. This mnemonic helps in identifying facial drooping, arm weakness, speech difficulties, and the importance of time in seeking emergency care. Choices A, C, and D are incorrect because the FAST acronym specifically pertains to stroke recognition, not the onset of labor, heart attacks, or migraines.
3. When preparing to perform a physical examination on an infant, what should the nurse do?
- A. Have the parent remove all clothing except the diaper.
- B. Instruct the parent not to feed the infant immediately before the examination.
- C. Allow the infant to suck on a pacifier during abdominal auscultation.
- D. Ensure the parent is present during the examination.
Correct answer: A
Rationale: For performing a physical examination on an infant, it is important to have the parent remove all clothing except the diaper to allow for a thorough examination while ensuring the infant remains comfortable. It is recommended not to feed the infant immediately before the examination but rather 1 to 2 hours after feeding when the baby is neither too drowsy nor too hungry. While a pacifier may be used during invasive assessments or if the infant is crying, it is not typically necessary during abdominal auscultation. Having the parent present during the examination is important for the infant's security and for the parent to understand the process; however, the clothing should still be removed except for the diaper to facilitate a comprehensive assessment.
4. A client has fallen asleep in his bed in the hospital. His heart rate is 65 bpm, his muscles are relaxed, and he is difficult to arouse. Which stage of the sleep cycle is this client experiencing?
- A. Stage 1
- B. Stage 2
- C. Stage 3
- D. Stage 4
Correct answer: C
Rationale: The client in this scenario is experiencing stage 3 of the sleep cycle. In stage 3, the individual has moved into deeper stages of sleep, making it difficult to arouse. Characteristics of stage 3 include relaxed muscles, a decrease in vital signs, and being very still. Stage 3 is a phase of non-REM sleep where the client progresses towards REM sleep and vivid dreams. Choices A, B, and D are incorrect. Stage 1 is characterized by light sleep, stage 2 is a slightly deeper sleep with sleep spindles and K-complexes, and stage 4 is the deepest stage of sleep with the slowest brain waves.
5. A 4-month-old child is at the clinic for a well-baby checkup and immunizations. Which of these actions is most appropriate when the nurse is assessing an infant's vital signs?
- A. The infant's radial pulse should be palpated, and the nurse should notice any fluctuations resulting from activity or exercise.
- B. The nurse should auscultate an apical rate for 1 minute and then assess for any normal irregularities, such as sinus dysrhythmia.
- C. The infant's blood pressure should be assessed by using a stethoscope with a large diaphragm piece to hear the soft muffled Korotkoff sounds.
- D. The infant's chest should be observed and the respiratory rate counted for 1 minute; the respiratory pattern may vary significantly.
Correct answer: B
Rationale: The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be counted by listening to the heart for 1 full minute to account for normal irregularities, such as sinus dysrhythmia. Children younger than 3 years of age have such small arm vessels; consequently, hearing Korotkoff sounds with a stethoscope is difficult. The nurse should use either an electronic blood pressure device that uses oscillometry or a Doppler ultrasound device to amplify the sounds. An infant's respiratory rate should be assessed by observing the infant's abdomen, not chest, because an infant's respirations are normally more diaphragmatic than thoracic. The nurse should auscultate an apical heart rate, not palpate a radial pulse, with infants and toddlers.
