1. The nurse is discussing sexually transmitted infections (STIs) with a 17-year-old student. Which cognitive development theory should the teaching plan be based on?

• A. Sensorimotor reactions
• B. Limited cause and effect understanding
• C. Abstract thinking
• D. Concrete thinking

Correct Answer: C

Rationale: The correct answer is C: 'Abstract thinking.' According to Piaget’s theory of cognitive development, adolescents, typically around the age of 12 and older, enter the formal operational stage where they can think abstractly and reason about hypothetical situations. When discussing complex topics like STIs with a 17-year-old student, it is essential to base the teaching plan on abstract thinking. Choice A, 'Sensorimotor reactions,' is incorrect as it pertains to the earliest stage in Piaget's theory (birth to 2 years old) focusing on sensory experiences and physical interactions. Choice B, 'Limited cause and effect understanding,' does not align with the cognitive abilities of a 17-year-old who is capable of more advanced thinking. Choice D, 'Concrete thinking,' is also incorrect as it refers to the stage before formal operations, where individuals think more concretely and struggle with abstract concepts.

2. Which nursing intervention should be included in the postoperative care of a child following a tonsillectomy?

• A. Encourage the child to blow the nose gently
• B. Notify the physician if mucus is observed in the emesis
• C. Position the child supine in the immediate postoperative period
• D. Avoid giving citrus juice

Correct Answer: D

Rationale: The correct answer is D: 'Avoid giving citrus juice.' Citrus juice can irritate the throat after a tonsillectomy, so it should be avoided. Choice A is incorrect because blowing the nose gently is not a recommended intervention following a tonsillectomy. Choice B is incorrect as mucus in emesis is not uncommon postoperatively and does not necessarily require physician notification. Choice C is incorrect as positioning the child supine immediately postoperatively can increase the risk of airway obstruction and should be avoided.

3. The nurse is caring for a child with an order of Ampicillin 250 mg IV in 30 mL of Normal Saline to infuse over 30 minutes. How many mL/hour should the nurse set the pump?

• A. 60
• B. 30
• C. 120
• D. 15

Correct Answer: A

Rationale: The correct setting for the infusion pump should be 60 mL/hour to deliver 30 mL in 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume to be infused (30 mL) by the total time for infusion (30 minutes) and then multiply by 60 to convert minutes to hours. Therefore, 30 mL / 30 minutes * 60 minutes/hour = 60 mL/hour. Choices B, C, and D are incorrect because they do not match the calculation based on the given parameters.

4. The nurse is caring for a 1-month-old infant diagnosed with Hirschsprung’s disease. Which treatment measure should be included in the plan of care?

• A. Barium Enema
• B. Surgical removal of the affected section of bowel
• C. High-fiber diet
• D. Permanent colostomy

Correct Answer: B

Rationale: The correct answer is B: Surgical removal of the affected section of bowel. Hirschsprung's disease is a congenital condition where a portion of the large intestine lacks nerve cells, leading to difficulties in passing stool. The definitive treatment for this condition is the surgical removal of the affected section of the bowel. Barium enema (Choice A) may be used for diagnosis but is not a treatment. A high-fiber diet (Choice C) is not effective in managing Hirschsprung's disease. A permanent colostomy (Choice D) is not the initial treatment for this condition in infants.

5. The mother of a 6-year-old boy who has recently had surgery for the removal of his tonsils and adenoids complains that he has begun sucking his thumb again. Which defense mechanism should the nurse include when responding to the mother?

• A. Repression
• B. Regression
• C. Rationalization
• D. Fantasy

Correct Answer: B

Rationale: The correct answer is B: Regression. Regression is a common defense mechanism where a child reverts to an earlier stage of development, such as thumb-sucking, to cope with stress. In this scenario, the 6-year-old boy is using thumb-sucking (a behavior typical of earlier developmental stages) as a way to deal with the stress of surgery. Repression (choice A) involves unconsciously blocking out thoughts or feelings, which is not applicable in this case. Rationalization (choice C) is a defense mechanism where illogical or unreasonable explanations are provided to justify behavior, which is not relevant here. Fantasy (choice D) refers to the use of imagination to escape from reality, which is also not the appropriate defense mechanism for the situation described.
