Question 1 of 5
Decreased pulmonary blood flow, right-to-left shunting, and deoxygenated blood reaching the systemic circulation are characteristic of:
Correct Answer: A
Rationale: Tetralogy of Fallot is the most common cyanotic heart defect, which includes a VSD, pulmonary stenosis, an overriding aorta, and ventricular hypertrophy. The blood flow is obstructed because the pulmonary stenosis decreases the pulmonary blood flow and shunts blood through the VSD, creating a right-to-left shunt that allows deoxygenated blood to reach the systemic circulation. A VSD alone creates a left-to-right shunt. The pressure in the left ventricle is greater than that of the right; therefore, the blood will shunt from the left ventricle to the right ventricle, increasing the blood flow to the lungs. No deoxygenated blood will reach the Systemic circulation. In patent ductus arteriosus, the pressure in the aorta is greater than in the pulmonary artery, creating a left-to-right shunt. Oxygenated blood from the aorta flows into the unoxygenated blood of the pulmonary artery. Transposition of the great arteries results in two separate and parallel circulatory systems. The only mixing or shunting of blood is based on the presence of associated lesions.
Question 2 of 5
The client is prescribed ipratropium (Atrovent) and albuterol (Proventil) via inhaler. Which instruction should the nurse include?
Correct Answer: A
Rationale: Albuterol, a bronchodilator, is used first to open airways, followed by ipratropium, an anticholinergic, to maintain bronchodilation. Simultaneous or single daily use is incorrect.
Question 3 of 5
Following the delivery of a healthy newborn, a client has developed thrombophlebitis and is receiving heparin IV. What are the signs and symptoms of a heparin overdose for which the nurse would need to observe during postpartum care of the client?
Correct Answer: D
Rationale: Hematuria, ecchymosis, and epistaxis are the most common signs and symptoms of a heparin overdose, indicating bleeding tendencies.
Question 4 of 5
An 8-year-old boy has been diagnosed with hemophilia. Which of the following diagnostic blood studies is characteristically abnormal in this disorder?
Correct Answer: A
Rationale: Partial thromboplastic time measures activity of thromboplastin, which depends on the intrinsic clotting factors deficient in children who are hemophiliacs. Platelet counts are normal in hemophilia. Hemophilia does not affect the complete blood count. Bleeding times are normal in hemophiliacs. They measure the time interval for the bleeding from small superficial wounds to cease.
Question 5 of 5
The nurse has just received the change of shift report and is preparing to make rounds. Which client should the nurse assess first?
Correct Answer: C
Rationale: The client admitted one hour ago with rales and shortness of breath indicates potential acute respiratory distress, possibly from pulmonary edema or pneumonia, requiring immediate assessment. The other clients are stable or less urgent.
