Which of the following disorders leads to cyanosis from deoxygenated blood entering the systemic arterial circulation?
- A. Aortic stenosis (AS)
- B. Coarctation of aorta
- C. Patent ductus arteriosus (PDA)
- D. Tetralogy of Fallot
Correct Answer: D
Rationale: Tetralogy of Fallot is a congenital heart defect characterized by four primary abnormalities: pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Due to the pulmonary stenosis, less blood reaches the lungs to be oxygenated, resulting in deoxygenated blood entering the systemic arterial circulation. This leads to cyanosis, which is often referred to as "Tet spells" in these patients. Cyanosis is the bluish discoloration of the skin and mucous membranes caused by the presence of deoxygenated hemoglobin. The other conditions listed do not typically result in deoxygenated blood entering the systemic arterial circulation and causing cyanosis.

An appropriate nursing action to include in the care of an infant with congenital heart disease who has been admitted with heart failure is:
- A. Positioning flat on the back
- B. Encouraging nutritional fluids
- C. Offering small frequent feedings
- D. Measuring the head circumference
Correct Answer: C
Rationale: Infants with congenital heart disease who have been admitted with heart failure may have difficulty feeding due to increased work of breathing and poor energy reserves. Offering small, frequent feedings can help prevent fatigue and provide adequate nutrition to support the infant's growth and recovery. It also helps to prevent overloading the heart with a large volume of fluids at once. This approach allows the infant to receive enough calories while reducing the risk of aspiration and conserving energy for feeding and breathing. Positioning the infant flat on the back may worsen respiratory distress, encouraging nutritional fluids alone may not address the feeding challenges faced by the infant, and measuring the head circumference is important for growth monitoring but may not be the priority when managing heart failure in this case.
A newborn has small, whitish, pinpoint spots over the nose, which the nurse knows are caused by retained sebaceous secretions. When charting this observation, the nurse identifies it as:
- A. Milia
- B. Lanugo
- C. Whiteheads
- D. Mongolian spots
Correct Answer: A
Rationale: Milia are small, whitish, pinpoint spots that commonly occur in newborns due to retained sebaceous secretions in the skin. They are commonly seen on the nose and can also appear on the cheeks and chin. Milia are not indicative of any illness and tend to disappear on their own without any treatment. They are a benign and temporary skin condition in newborns.
The nurse is conducting a staff in-service on childhood-acquired heart diseases. Which is a major clinical manifestation of rheumatic fever?
- A. Polyarthritis
- B. Osler nodes
- C. Janeway spots
- D. Splinter hemorrhages of distal third of nails
Correct Answer: A
Rationale: Rheumatic fever is a systemic inflammatory condition that can develop as a complication of untreated or inadequately treated streptococcal infections, such as strep throat. One of the major clinical manifestations of rheumatic fever is polyarthritis, which is characterized by inflammation and pain in multiple joints. It typically involves large joints like the knees, ankles, elbows, and wrists. Polyarthritis in rheumatic fever is migratory in nature, meaning the joint pain shifts from one joint to another over a period of time. Other common clinical manifestations of rheumatic fever include carditis (inflammation of the heart), chorea (involuntary movements), subcutaneous nodules, and erythema marginatum (rash).
Which of the ff are the most significant symptoms of Hodgkin's disease category B? Choose all that apply
- A. Fever
- B. Anemia
- C. Night sweats
- D. Thrombocytopenia
Correct Answer: C
Rationale: The most significant symptoms of Hodgkin's disease with category B classification are fever, weight loss, and night sweats. Night sweats are particularly characteristic of Hodgkin's disease and are considered one of the B symptoms along with fever and weight loss. Anemia and thrombocytopenia are not typically classified as specific symptoms of Hodgkin's disease category B.
