1. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

• A. Isotonic dehydration
• B. Hypotonic dehydration
• C. Hypertonic dehydration
• D. Hyperosmotic dehydration

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

2. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.

3. An anxious 12-year-old child receives an injection from the nurse and sighs with relief when it is done. After a moment of reflection, the girl asks the nurse, 'Is it hard to give someone an injection?' This child’s question is evidence that the child has developed which cognitive skill?

• A. Conservation
• B. Accommodation
• C. Decentering
• D. Class inclusion

Correct answer: C

Rationale: The correct answer is C: Decentering. Decentering is the ability to consider multiple aspects of a situation, which the child's question demonstrates. In this scenario, the child's question shows that she is thinking beyond her own experience and considering the difficulty or complexity of giving an injection from the nurse's perspective. Choices A, B, and D are incorrect. Conservation refers to understanding that certain properties of an object remain the same despite changes in its appearance. Accommodation is the process of adjusting existing knowledge or creating new mental categories to incorporate new information. Class inclusion involves understanding the relationship between a whole set and its subsets, which is not demonstrated in the child's question.

4. The LPN is caring for a 1-month-old patient post-surgery. Which pain scale is expected to be used to evaluate post-op pain?

• A. Oucher
• B. Wong-Baker FACES
• C. FLACC
• D. 0-10 pain scale

Correct answer: C

Rationale: The FLACC (Face, Legs, Activity, Cry, Consolability) scale is commonly used to assess pain in infants and young children who are unable to verbally communicate their pain. This scale is particularly useful in assessing post-operative pain in infants as it evaluates different behaviors and physiological responses to pain. The Oucher scale is more commonly used with children who are older and can provide self-report of pain intensity. Wong-Baker FACES scale is primarily used with children who are older and can indicate their pain level by pointing to facial expressions. The 0-10 pain scale is typically used with older children and adults who can rate their pain on a numerical scale.

5. What is the most effective way to prevent sudden infant death syndrome (SIDS)?

• A. Use a firm mattress
• B. Place the baby on their back to sleep
• C. Keep the room warm
• D. Breastfeed exclusively

Correct answer: B

Rationale: The correct answer is to place the baby on their back to sleep. This position is the most effective way to prevent sudden infant death syndrome (SIDS) according to research and recommendations from healthcare providers. Choice A, using a firm mattress, is important for infant safety but not as directly related to preventing SIDS. Keeping the room warm, as mentioned in choice C, is not recommended as it may increase the risk of SIDS. While breastfeeding has many benefits, choice D, breastfeeding exclusively is not the most effective method for preventing SIDS.
