Correct Answer: B

Rationale: The correct answer is B: 'Observe for projectile vomiting.' Projectile vomiting is a classic sign of pyloric stenosis, caused by obstruction at the pylorus. Choice A is incorrect as metabolic alkalosis, not acidosis, often occurs due to the loss of hydrochloric acid from persistent vomiting. Choice C is incorrect as frequent, small feedings are preferred to prevent overloading the stomach. Choice D is incorrect as placing the infant in an upright position after feeding can help reduce reflux.

Correct Answer: B

Rationale: The correct answer is B, symbolic functioning. Symbolic functioning refers to children using objects, actions, or ideas to represent other objects, actions, or ideas. In this scenario, pretending a sheet is a cape to mimic a superhero demonstrates the child's ability to engage in symbolic play. Choice A, artificialism, is incorrect as it refers to the belief that inanimate objects have lifelike qualities. Choice C, critical thinking, does not directly relate to the imaginative play described in the question. Choice D, dramatic play, is close but not as precise as symbolic functioning, which specifically highlights the use of objects to represent something else.

Correct Answer: B

Rationale: Socializing, using clich©s, and defending a situation are all barriers to effective therapeutic communication. Silence is a useful tool in therapeutic communication.

Correct Answer: C

Rationale: The correct answer is C: The insertion of tympanostomy (pressure equalizing) tubes. This treatment measure is appropriate for a child with recurrent otitis media as it helps drain fluid from the middle ear and prevent further infections. Adenoidectomy (choice B) involves the removal of the adenoids, which may not directly address the ear infections. Antibiotic treatment (choice A) has already been ineffective in this case, so alternative measures are necessary. Tonsillectomy (choice D) is not typically indicated for otitis media unless there are specific reasons such as enlarged tonsils contributing to the condition.

Correct Answer: B

Rationale: Allowing adolescents to express their feelings helps them feel heard and supported, which is crucial for effective communication.
