Exam Cram NCLEX RN Practice Questions
1. The nurse is assessing children in a pediatric clinic. Which statement is true regarding the measurement of blood pressure in children?
- A. Blood pressure guidelines for children are based on age.
- B. Phase II Korotkoff sounds are the best indicator of systolic blood pressure in children.
- C. Using a Doppler device is recommended for accurate blood pressure measurements until adolescence.
- D. The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children.
Correct answer: D
Rationale: The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults. Blood pressure guidelines for children are based on more than just age, but also sex and height. Phase I Korotkoff, not Phase II, is the best indicator of systolic blood pressure. The true statement regarding the measurement of blood pressure in children is that the disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults.
2. Which playroom activities should the nurse organize for a small group of 7-year-old hospitalized children?
- A. Sports and games with rules.
- B. Finger paints and water play.
- C. "Dress-up"? clothes and props.
- D. Chess and television programs
Correct answer: A
Rationale: For 7-year-old children, play serves an important role in developing cooperation, logical reasoning, and social skills. Organizing sports and games with rules is beneficial as it helps children understand the importance of rules, promotes teamwork, and fosters social interactions. Finger paints and water play, while fun, may not target the specific developmental needs of this age group. Similarly, 'Dress-up' clothes and props can encourage imaginative play but may not necessarily promote cooperation and logical reasoning. Chess and television programs are more suited for older children and may not engage 7-year-olds as effectively in developing the desired skills.
3. A 2-year-old child has been brought to the clinic for a well-child checkup. What is the best way for the nurse to begin the assessment?
- A. Ask the parent to place the child on the examining table.
- B. Have the parent remove all of the child's clothing before the examination.
- C. Allow the child to keep a security object such as a toy or blanket during the examination.
- D. Initially focus the interactions on the child, essentially ignoring the parent until the child's trust has been obtained.
Correct answer: C
Rationale: The best place to examine the toddler is on the parent's lap. Toddlers understand symbols; therefore, a security object is helpful. Initially, the focus is more on the parent, which allows the child to adjust gradually and to become familiar with you. A 2-year-old child does not like to take off his or her clothes. Therefore, ask the parent to undress one body part at a time.
4. What does preload refer to?
- A. The volume of blood entering the left side of the heart
- B. The volume of blood entering the right side of the heart
- C. The pressure in the venous system that the heart must overcome to pump the blood
- D. The pressure in the arterial system that the heart must overcome to pump the blood
Correct answer: B
Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.
5. A client is having difficulties reading an educational pamphlet. He cannot find his glasses. In order to read the words, he must hold the pamphlet at arm's length, which allows him to read the information. Which vision deficit does this client most likely suffer from?
- A. Cataracts
- B. Glaucoma
- C. Astigmatism
- D. Presbyopia
Correct answer: D
Rationale: Presbyopia is a condition that occurs when the lens of the eye loses accommodation and is unable to focus light on objects nearby. As a result, clients are unable to see or read items up close but may have success when holding the same item at arm's length. Many clients with presbyopia must wear bifocals, but long-distance vision remains unaffected. Cataracts involve clouding of the eye's lens, leading to blurry vision. Glaucoma is associated with increased intraocular pressure that damages the optic nerve, causing vision loss. Astigmatism is a refractive error where the cornea or lens has an irregular shape, leading to distorted or blurred vision.
