1. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Coarctation of the aorta
• C. Transposition of the great arteries
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

2. The nurse is caring for an adolescent who is overweight. Which of the following psychological effects of being overweight during adolescence will the nurse consider when planning care for the adolescent?

• A. Poor body image
• B. Sexual promiscuity
• C. Feelings of contempt for thin peers
• D. Lack of independence

Correct answer: A

Rationale: Adolescents who are overweight often struggle with poor body image, which can lead to low self-esteem and mental health issues. Addressing body image concerns and promoting healthy lifestyle changes are important aspects of care. Choices B, C, and D are incorrect. Sexual promiscuity is not a direct psychological effect of being overweight; feelings of contempt for thin peers are not a common or recommended psychological response; lack of independence is a broad term that does not specifically relate to the psychological effects of being overweight.

3. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:

• A. Teratogens
• B. Heterozygous
• C. Inborn errors
• D. Multifactorial

Correct answer: A

Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.

4. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

5. What term is appropriate terminology to use for an infant whose intrauterine growth rate was slowed and whose birth weight falls below the 10th percentile on intrauterine growth charts?

• A. Postterm
• B. Postmature
• C. Low birth weight
• D. Small for gestational age

Correct answer: D

Rationale: The correct answer is D, 'Small for gestational age.' A small for gestational age, or small-for-date, infant is any child whose intrauterine growth rate was slowed and whose birth weight falls below the 10th percentile on intrauterine growth curves. Choices A and B, 'Postterm' and 'Postmature,' refer to infants born after 42 weeks of gestational age regardless of birth weight, and do not specifically address growth rate. Choice C, 'Low birth weight,' refers to infants with a birth weight less than 2500 g (5.5 pounds) regardless of gestational age, which is a different classification compared to being small for gestational age.
