During the first 4 days of hospitalization, Eric, age 18 months, cried inconsolably when his parents left him, and he refused the staff's attention. Now the nurse observes that Eric appears to be "settled in" and unconcerned about seeing his parents. The nurse should interpret this as which statement?

Correct Answer: A

Rationale: Eric's change in behavior from crying inconsolably and refusing staff attention to now appearing settled and unconcerned about his parents leaving indicates that he has successfully adjusted to the hospital environment. This adaptation is a positive sign that Eric has become more comfortable with his surroundings and has developed a sense of security within the hospital setting. As a result, the nurse can interpret this change as Eric successfully acclimating to his new environment.

Correct Answer: B

Rationale: The psychological effect of being obese during adolescence often includes a poor body image. Adolescence is a critical period for body image development, and being obese can lead to negative perceptions about one's appearance and self-worth. Individuals who are obese may experience low self-esteem, perpetuated by societal stereotypes and stigmas surrounding body weight. This poor body image can contribute to mental health issues such as depression and anxiety, as well as impact social relationships and overall well-being during this crucial stage of development.

Correct Answer: B

Rationale: This statement is incorrect because drinking milk alone without other foods is not necessary for someone with lactose maldigestion intolerance. Mixing milk with other foods or consuming dairy products alongside other foods can sometimes help to reduce symptoms. Therefore, the adolescent does not need further teaching if they make this statement. The other statements are all appropriate for managing lactose maldigestion intolerance.

Correct Answer: B

Rationale: Acute glomerulonephritis is commonly associated with a preceding streptococcal infection, particularly Group A beta-hemolytic streptococcal infection such as strep throat or impetigo. The infection triggers an abnormal immune response leading to inflammation of the glomeruli in the kidneys. This inflammation impairs the kidneys' ability to filter waste and excess fluids from the blood, resulting in symptoms such as hematuria (blood in urine), proteinuria (protein in urine), hypertension, and edema. Other causes such as renal vascular disorders, structural anomalies of the genitourinary tract, or urinary tract infections are not typically linked to acute glomerulonephritis.

Correct Answer: C

Rationale: The correct statement indicating that the parents have understood the teaching is: "The red blood cell count should begin to improve with these injections." Recombinant human erythropoietin (rHuEPO) is a hormone used to stimulate red blood cell production in patients with chronic renal failure. By increasing red blood cell production, rHuEPO can help combat anemia, a common complication of chronic renal failure. Therefore, the improvement of the red blood cell count is an expected outcome of administering rHuEPO injections in patients with chronic renal failure. The other statements are not accurate regarding the effects of rHuEPO injections.
