NCLEX NCLEX-PN Online Questions & Answers

• Question 441:

  The school nurse is conducting health screenings on schoolchildren. During the screening, she identifies a child with the behavioral characteristics of attention deficit disorder.

  Which of the following behaviors is consistent with this disorder?

  A. slow speech development
  B. overreaction to stimuli from the surroundings
  C. inability to carry on a conversation
  D. concrete thinking
  B. overreaction to stimuli from the surroundings

  ---

  Children with attention deficit disorder are easily distracted but are able to carry on a conversation. Concrete thinking is more indicative of age, and slow speech development has more to do with other learning disabilities.

• Question 442:

  A nurse is assessing a patient's breath sounds. The patient has had a pneumonectomy to the right lung performed 48 hours ago. Which of the following conditions most likely exists?

  A. Decreased breath sound volume
  B. Elevated tidal volume
  C. Elevated respiratory capacity
  D. Wheezing
  A. Decreased breath sound volume

  ---

  Explanation Explanation/Reference:Breath sounds would be softer.

• Question 443:

  Which statement about glaucoma is true and accurate?

  A. Acute angle-closure glaucoma is an ocular emergency.
  B. Acute angle-closure glaucoma leads to the loss of peripheral vision and tunnel vision.
  C. Primary open-angle glaucoma leads to eye pain, nausea and vomiting, blurry vision and halos.
  D. Bubbles are implanted to protect the retina from the glaucoma.
  A. Acute angle-closure glaucoma is an ocular emergency.

  ---

  Explanation Explanation/Reference:Acute angle-closure glaucoma is an ocular emergency and it is characterized with eye pain, nausea and vomiting, blurry vision and halos. The signs and symptoms of primary open-angle glaucoma are the loss of peripheral vision and tunnel vision. Bubbles are placed to treat retinal detachments, another ocular emergency and laser peripheral iridotomy to decrease intraocular pressure is used for the treatment of glaucoma.

• Question 444:

  A 21-year-old college student has just learned that she contracted genital herpes from her sexual partner. After completing the initial history and assessment, the nurse has data concerning areas pertinent to the disease.

  The data is likely to include all but which of the following?

  A. voiding patterns
  B. characteristics of lesions
  C. vaginal discharge
  D. prior history of varicella
  D. prior history of varicella

  ---

  The other choices are common reasons for which clients with herpes seek care.

• Question 445:

  A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication.

  Rather than wait for steady state to be achieved, the physician might order __________.

  A. a maintenance dose
  B. a loading dose
  C. a medication with no first-pass effect
  D. the medication to be given intravenously
  B. a loading dose

  ---

  A loading or priming dose rapidly establishes a therapeutic plasma drug level. It can be calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose maintains a therapeutic level after the loading dose. It takes five drug half-lives to achieve steady state if no loading dose is given. A medication with no first-pass effect is similar to a maintenance dose. Intravenous administration provides excellent drug bioavailability, but one dose will not achieve a therapeutic plasma level.

• Question 446:

  As part of the teaching plan for a client with type I diabetes mellitus, the nurse should include that carbohydrate needs might increase when __________.

  A. an infection is present
  B. there is an emotional upset
  C. a large meal is eaten
  D. active exercise is performed
  D. active exercise is performed

  ---

  Explanation Explanation/Reference:Active exercise increases insulin sensitivity, thus lowering blood glucose levels. Additional carbohydrates might be needed to balance the usual insulin dose. All of the other choices increase blood glucose levels.

• Question 447:

  With a breech presentation, the nurse must be particularly alert for __________.

  A. quickening
  B. ophthalmia neonatorum
  C. pica
  D. prolapsed umbilical cord
  D. prolapsed umbilical cord

  ---

  Explanation Explanation/Reference:Prolapsed umbilical cord is the descent of the umbilical cord into the vagina before the fetal presenting part and compression of the cord between the presenting part and the maternal pelvis, compromising or completely cutting off fetoplacental perfusion. This is an emergency situation; immediate delivery should be attempted to save the fetus.

• Question 448:

  The greatest time savers when planning client care include all of the following except __________.

  A. reacting to the crisis of the moment
  B. setting goals
  C. planning
  D. specifying priorities
  A. reacting to the crisis of the moment

  ---

  The greatest time-savers when planning client care are activities that facilitate focus and completion of priority items. Time-savers include setting goals, establishing priorities, planning tasks, delegating where appropriate, re-assessment, and ongoing evaluation of needs.

• Question 449:

  The LPN discovers an unconscious 8-year-old in the bathroom. She does a quick assessment and discovers he is not breathing and does not have a pulse. The LPN is alone and does not have quick access to a call button. What should she do first?

  A. Look for help and an AED, then give 2 minutes of CPR at a compression-ventilation ratio of 30:2.
  B. Give 2 minutes of CPR at a compression-ventilation ratio of 30:2. Then, look for help and an AED, and return and resume CPR.
  C. Give 2 minutes of CPR at a compression-ventilation ratio of 15:2. Then, look for help and an AED, and return and resume CPR.
  D. Look for help and an AED, then give 1 minute of CPR at a compression-ventilation ratio of 15:2.
  B. Give 2 minutes of CPR at a compression-ventilation ratio of 30:2. Then, look for help and an AED, and return and resume CPR.

• Question 450:

  A corporate executive works 60-80 hours a week. The client is experiencing some physical signs of stress. The nurse teaches the client biofeedback techniques. This is an example of __________ health-promotion interventions.
