The nurse is teaching a nursing student about respiratory distress syndrome. Which statement by the student nurse demonstrates understanding?
Respiratory distress, syndrome occurs in babies with frequent colds.
Respiratory distress syndrome occurs in premature and low-birth-weight babies.
Respiratory distress syndrome occurs in babies with genetic allergies.
Respiratory distress syndrome occurs in babies stressed during the pregnancy.
The Correct Answer is B
A. Respiratory distress syndrome occurs in babies with frequent colds. This statement is inaccurate; respiratory distress syndrome (RDS) is not associated with frequent colds.
B. Respiratory distress syndrome occurs in premature and low-birth-weight babies. This statement accurately describes RDS, as it is primarily seen in premature infants due to insufficient surfactant production.
C. Respiratory distress syndrome occurs in babies with genetic allergies. RDS is not directly related to genetic allergies; it is a condition primarily linked to prematurity and lung maturity.
D. Respiratory distress syndrome occurs in babies stressed during the pregnancy. While stress during pregnancy can affect outcomes, RDS is specifically associated with lung development in premature infants rather than stress alone.

Correct Answer is A
Explanation
A. BUN 45 mg/dL and creatinine 8 mg/dL: These levels indicate significant kidney impairment; elevated BUN and creatinine levels are typical in chronic kidney disease.
B. BUN 8 mg/dL and creatinine 0.7 mg/dL: These values are within normal limits and suggest good kidney function, not indicative of chronic kidney disease.
C. BUN 10 mg/dL and creatinine 0.3 mg/dL: These values are much lower than expected in chronic kidney disease, indicating normal renal function.
D. BUN 23 mg/dL and creatinine 1.0 mg/dL: While these levels show mild elevation, they do not reflect the more severe impairment typically seen in chronic kidney disease.
Correct Answer is C
Explanation
A. "Use the peak expiratory flow meter once per week." The peak expiratory flow meter is usually recommended for daily use in asthma management to monitor lung function and detect any changes early.
B. "Take cromolyn sodium at the first sign of breathing difficulty." Cromolyn sodium is a mast cell stabilizer and is used as a preventative medication rather than for quick relief of symptoms, so it should be taken regularly as prescribed, not only when symptoms arise.
C. "Avoid triggers that cause an attack." Avoiding known asthma triggers is an important part of asthma management to prevent attacks and exacerbations.
D. "You should stop playing basketball, but you can swim instead." Exercise should not necessarily be avoided; instead, it should be managed appropriately with pre-treatment if needed. Avoiding all sports activities is not generally recommended.
