• Question 751:

  Babies should double their birth weight by the __________.

  A. 5th to 6th month

  B. 3rd to 4th month

  C. 4th to 5th month

  D. 5th to 7th month

  Correct Answer: C

  Most babies should have doubled their birth weight by 6 months, but many may have doubled their birth

  weight by 5 months of age.

  Newborns gain about five to seven ounces per week for the first 3 to 4 months of life.

  By their first birthday, many babies have tripled their birth weight.

• Question 752:

  Which of these breath sounds is considered normal and not adventitious?

  A. Vesicular breath sounds

  B. Fine rales

  C. Rhonchi

  D. Wheezes

  Correct Answer: A

  Vesicular breath sounds are normal breath sounds.

  Rales, fine and coarse, rhonchi and wheezes are all abnormal, adventitious breath sounds.

• Question 753:

  The hormone produces mother's milk is __________.

  A. Progesterone

  B. Estrogen

  C. Prolactin

  D. Colostrum

  Correct Answer: C

  Prolactin is a protein that is best known for its role in enabling females to produce milk, but it also has

  other functions, such as regulating the immune system.

  Progesterone has many roles relating to the development of the fetus during pregnancy.

  Estrogens are best known for their importance in both menstrual and estrous reproductive cycles.

  Colostrum is the most nutrient dense part of breast milk produced during the postpartum stage.

• Question 754:

  How many daily feedings are considered normal for a newborn?

  A. 8 to 10

  B. 10 to 12

  C. 6 to 8

  D. 12 to 14

  Correct Answer: B

  An average newborn's stomach empties every 1.5 hours, so common feeding times occur about every 2 hours during a 24-hour period; therefore, 10 to 12 feedings per day is typical. Frequent breastfeeds increase a mother's prolactin levels, and high prolactin levels are required to establish an adequate milk supply. A higher-frequency of feedings help babies compensate for the lower caloric density of the milk.

• Question 755:

  Which of the following is a hazard of immobility?

  A. Loss of bone calcium.

  B. Increased vital capacity.

  C. Venous vasoconstriction.

  D. A positive nitrogen balance.

  Correct Answer: A

  One of the hazards of immobility is the loss of calcium from the bones that results from non-weight bearing by the immobilized patient. Other complications, or hazards, of immobility include muscle weakness, muscular atrophy, contractures, disuse osteoporosis, hypostatic pneumonia, pooled respiratory secretions, atelectasis, decreased respiratory movement, decreased, not increased, vital capacity, shallow respirations, diminished cardiac reserve, orthostatic hypotension, venous stasis, venous vasodilation, not vasoconstriction, emboli, dependent edema, stiff and painful joints, thrombophlebitis, urinary stasis, renal stones, urinary retention, urinary incontinence, urinary tract infections, pressure ulcers, diminished metabolic rate, a negative, not positive, nitrogen balance, a negative calcium balance, constipation and depression.

• Question 756:

  Which pain assessment scale is used exclusively for infants and neonates from 32 weeks of gestation to six months of age?

  A. The PEPPS pain scale

  B. The FLACC pain scale

  C. The Faces pain scale

  D. The CRIES pain scale

  Correct Answer: D

  The CRIES Pain scale is used exclusively for infants and neonates from 32 weeks of gestation to six months of age. This scale has five behavioral measurements that are scored from 0 to 2; the behavioral measurements include the infant's crying, requirements for increased oxygen, increased vital signs, expression, and sleepiness. The PEPPS pain scale (Pre-Verbal, Early Verbal Pediatric Pain Scale is used to assess and measure pain among toddlers. The Face, Legs, Activity, Crying, Consolability Scale (FLACC) is used for infants over two months of age and children up to three years of age. The Faces Pain Scale contains cartoon like pictures of six faces ranging from 0, or "no hurt" to 10 which represents "the worst hurt". It is used for pediatric patients who are three years of age and older.

• Question 757:

  You have been assigned to care for a neonate who has been diagnosed with the Tetralogy of Fallot. The mother asks you what the Tetralogy of Fallot is.

  How should you respond to this mother?

  A. "The Tetralogy of Fallot is a congenital gastrointestinal disorder"

  B. "The Tetralogy of Fallot is a congenital cardiac disorder"

  C. "The Tetralogy of Fallot will affect the baby's reflexes"

  D. "The Tetralogy of Fallot will affect the baby's ability to breastfeed"

  Correct Answer: B

  The Tetralogy of Fallot is a congenital cardiac disorder that is classified as a cyanotic, rather than acyanotic, congenital heart disorder that is characterized with abnormal cardiac anomalies. There is no relationship between the Tetralogy of Fallot and reflexes or breastfeeding.

• Question 758:

  Which quality assurance or performance improvement technique is used to identify underlying process flaws?

  A. Small group process

  B. Root cause analysis

  C. People at fault process

  D. Cause and effect

  Correct Answer: B

  Root cause analysis is a quality assurance or performance improvement technique that is used to identify the underlying, root causes of a problem. Root cause analysis focuses on process flaws and NOT on people who have erred or made a mistake. A cause and effect diagram may be used for root cause analysis but it, in itself, is not a quality assurance or performance improvement technique. Although small groups participate in quality assurance or performance improvement activities, small groups are not a quality assurance or performance improvement technique.

• Question 759:

  Which cardiac arrhythmia can be either acquired or congenital and can spontaneously disappear on its own or lead to ventricular fibrillation?

  A. Wenckebach

  B. Premature arterial contractions

  C. Torsades de pointes

  D. Premature ventricular contractions

  Correct Answer: C

  Torsades de pointes, a polymorphic ventricular tachycardia, can be either congenital or acquired; at times,

  it can spontaneously terminate but it frequently leads to ventricular fibrillation. In some cases, cardiac

  death can occur with the first episode.

  All of the other cardiac arrhythmias, or dysrhythmias, are acquired and not congenital.

• Question 760:

  Which atrioventricular heart block is also referred to as Mobitz II?

  A. Third-degree atrioventricular heart block.

  B. Second-degree atrioventricular heart block.

  C. First-degree atrioventricular heart block.

  D. Complete heart block.

  Correct Answer: A

  Third-degree atrioventricular heart block is also referred to as Mobitz II; this type of heart block occurs

  when the AV node impulses are blocked as they try to reach the ventricles.

  First degree heart block occurs when the AV node impulse is delayed.

  Second degree heart block, as referred to as Mobitz I and Wenckebach, occurs when there are

  progressive conduction delays through the AV node that alters the PR and QRS intervals.

  Complete heart block blocks all atrial impulses to the ventricle.
