The nurse caring for a child diagnosed with a patent ductus arteriosus should base planning on which fact concerning this disorder?
- A. It involves an opening between the two atria.
- B. It produces abnormalities in the atrial septum.
- C. It involves an opening between the two ventricles.
- D. It involves an artery that connects the aorta and the pulmonary artery.
Correct Answer: D
Rationale: Patent ductus arteriosus is described as an artery that connects the aorta and the pulmonary artery during fetal life. It generally closes spontaneously within a few hours to several days after birth. It allows abnormal blood flow from the high-pressure aorta to the low-pressure pulmonary artery, resulting in a left-to-right shunt. The remaining options are not characteristics of this cardiac defect.

A client with pneumonia is receiving oxygen therapy. The nurse notes cyanosis and a respiratory rate of 32 breaths/min. What should the nurse do first?
- A. Increase the oxygen flow rate.
- B. Notify the physician.
- C. Encourage coughing and deep breathing.

A 9-year-old child is newly diagnosed with type 1 diabetes mellitus. The nurse is planning for home care with the child and the family and determines that which is an age-appropriate activity for health maintenance?
- A. Administering insulin drawn up by an adult
- B. Self-administering insulin with adult supervision
- C. Making independent decisions with regard to sliding-scale coverage of insulin
- D. Having an adult assist in the self-administration of insulin and glucose monitoring
Correct Answer: B
Rationale: School-age children have the cognitive and motor skills to draw up and administer insulin with adult supervision. Developmentally, they do not yet have the maturity to make independent decisions such as about sliding-scale coverage without adult validation. Options requiring adult to manage insulin administration and glucose monitoring suppress the maximum level of independence appropriate to the level of this child.
Identify this cardiac rhythm strip. Fill in the blank. A. Idioventricular Rhythm B. Bundle Branch Block C. Sinus bradycardia D. Atrial Flutter
- B. Idioventricular Rhythm
- C. Bundle Branch Block
- D. Sinus bradycardia
- E. Atrial Flutter
Correct Answer: C
Rationale: Sinus bradycardia is characterized by a regular rhythm with a rate below 60 beats per minute, assuming the strip shows this pattern.
The nurse reviewing the electrocardiogram (ECG) rhythm strip of a client with a history of a myocardial infarction (MI) notes that the PR intervals are 0.16 seconds. The nurse should arrive at which interpretation of this assessment data?
- A. A normal finding
- B. An abnormal finding
- C. An impending reinfarction
- D. First-degree atrioventricular (AV) block
Correct Answer: A
Rationale: The PR interval represents the time it takes for the cardiac impulse to spread from the atria to the ventricles. The PR interval range is 0.12 to 0.2 seconds. Therefore, the finding is normal. The remaining options all indicate an abnormal finding, so they are not appropriate responses.
