1. Which finding suggests fluid volume deficit in an infant presenting with vomiting and diarrhea for 2 days?

• A. Increased blood pressure
• B. A sunken fontanel
• C. Decreased pulse rate
• D. Low urine specific gravity

Correct answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

2. What is a physical characteristic of infants whose mothers smoked during pregnancy?

• A. Being large for gestational age
• B. Growth restriction in weight only
• C. Preterm but size appropriate for gestational age
• D. Growth restriction in weight, length, and chest and head circumference

Correct answer: D

Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.

3. The parent of a 2-week-old infant asks the nurse if fluoride supplements are necessary because the infant is exclusively breastfed. What is the nurse's best response?

• A. The infant needs to begin taking them now.
• B. Supplements are not needed if you drink fluoridated water.
• C. The infant may need to begin taking them at age 6 months.
• D. The infant can have infant cereal mixed with fluoridated water instead of supplements.

Correct answer: C

Rationale: Breastfed infants may need fluoride supplements starting at 6 months if they are not receiving fluoride from other sources, such as drinking water.

4. A child is refusing to use the potty and having accidents, even though he has achieved toilet training. This is an example of which type of behavior?

• A. Positive reinforcement
• B. Desensitization
• C. Phobia
• D. Regression

Correct answer: D

Rationale: The correct answer is D, regression. Regression occurs when a child reverts to an earlier behavior, such as having accidents after being successfully toilet trained. This regression often happens due to stress or changes in routine. Choices A, B, and C are incorrect because positive reinforcement involves encouraging desired behavior, desensitization is a process of reducing sensitivity to a stimulus, and phobia is an intense fear or aversion to a specific object or situation, none of which directly apply to the described situation of the child having accidents after being toilet trained.

5. A 5-year-old has patient-controlled analgesia (PCA) for pain management after abdominal surgery. What information does the nurse include in teaching the parents about the PCA?

• A. The child may not be pain-free.
• B. The parents or nurse may push the button for a bolus if needed.
• C. The pump allows for a continuous basal rate to deliver a constant amount of medication for pain control.
• D. Monitoring is required every 1 to 2 hours to assess patient response.

Correct answer: C

Rationale: The correct answer is C because the PCA pump can be programmed to deliver a continuous basal rate of pain medication to maintain pain control. While the goal of PCA is effective pain relief, it does not guarantee a pain-free state. In the case of a 5-year-old child, the parents or nurse can administer boluses if necessary since the child may not fully comprehend using the PCA button. Monitoring every 1 to 2 hours for patient response is adequate and there is no need for monitoring every 15 minutes, as stated in choice D, unless specific circumstances dictate more frequent monitoring.
