1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?
- A. Metabolic acidosis
- B. Respiratory alkalosis
- C. Metabolic and respiratory acidosis
- D. Metabolic and respiratory alkalosis
Correct answer: D
Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.
2. An intravenous line is needed in a school-age child. What medication is an appropriate analgesic for use with this patient?
- A. TAC (tetracaine, epinephrine [Adrenalin], cocaine) 15 minutes before the procedure.
- B. A transdermal fentanyl (Duragesic) patch at the site of venipuncture.
- C. EMLA (eutectic mixture of local anesthetics) immediately before the procedure.
- D. LMX (4% liposomal lidocaine cream) 30 minutes before the procedure.
Correct answer: D
Rationale: LMX is an effective analgesic agent when applied to the skin 30 minutes before a procedure. It eliminates or reduces the pain from most procedures involving skin puncture. TAC provides skin anesthesia about 15 minutes after application to nonintact skin, making it more suitable for wound suturing. Transdermal fentanyl patches are designed for continuous pain control, not rapid pain control needed for a procedure like venipuncture. EMLA, for maximum effectiveness, must be applied approximately 60 minutes before the procedure, making it less suitable for immediate pain relief required for intravenous line placement.
3. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?
- A. Gently tap over the site.
- B. Apply a cold compress to the site.
- C. Raise the extremity above the level of the body
- D. Use a rubber band as a tourniquet for 5 minutes.
Correct answer: A
Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.
4. The nurse observes that a newborn is having problems after birth. What should indicate a tracheoesophageal fistula?
- A. Jitteriness
- B. Meconium ileus
- C. Excessive frothy saliva
- D. Increased need for sleep
Correct answer: C
Rationale: Excessive frothy saliva is a hallmark sign of tracheoesophageal fistula. The abnormal connection between the esophagus and trachea causes difficulty in swallowing, leading to an accumulation of saliva in the mouth. This symptom is crucial for early identification and management of tracheoesophageal fistula. Choices A, B, and D are incorrect as they are not specific indicators of tracheoesophageal fistula.
5. 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.
