Hypoplastic left heart syndrome is characterized by underdevelopment of
- A. Pulmonary veins, ventricles and aortic valve
- B. Left ventricle, atrium and pulmonary vessels
- C. Aortic arch, venacava and right atrium
- D. Left ventricle, aortic valve and arch
Correct Answer: D
Rationale: Rationale:
1. Hypoplastic left heart syndrome involves underdevelopment of the left ventricle, aortic valve, and aortic arch.
2. The left ventricle is essential for pumping oxygenated blood to the body.
3. Aortic valve controls blood flow from the left ventricle to the aorta.
4. Aortic arch connects the ascending and descending aorta.
Summary:
A - Incorrect, as it includes pulmonary veins not related to hypoplastic left heart syndrome.
B - Incorrect, as it includes structures not primarily affected in this condition.
C - Incorrect, as it does not involve structures related to the left side of the heart.

The MAIN function of surfactant factor is to
- A. Prevent alveoli of the lungs from collapsing
- B. Initiate breathing of the neonate at birth
- C. Enhance maturity of respiratory centre in the brain
- D. Regulate breathing immediately the baby is born
Correct Answer: A
Rationale: The correct answer is A: Prevent alveoli of the lungs from collapsing. Surfactant reduces surface tension in the alveoli, preventing them from collapsing during exhalation and maintaining lung compliance. B, C, and D are incorrect because surfactant primarily affects lung mechanics, not the initiation of breathing, maturity of the respiratory center, or immediate regulation of breathing upon birth.
The complication that is associated with hyperemesis gravidarum is
- A. Wernicke’s encephalopathy
- B. Sheehan’s syndrome
- C. Maurice encephalitis
- D. Antepartum bleeding
Correct Answer: A
Rationale: The correct answer is A: Wernicke's encephalopathy. Hyperemesis gravidarum is severe nausea and vomiting during pregnancy. Wernicke's encephalopathy is a neurological complication due to thiamine deficiency, which can occur in severe cases of vomiting, leading to impaired brain function. Sheehan's syndrome is a complication of postpartum pituitary necrosis. Maurice encephalitis is a fictional term not related to this context. Antepartum bleeding is not a typical complication of hyperemesis gravidarum. Therefore, the correct answer is A due to the potential neurological impact of severe vomiting on thiamine levels.
The AGACNP is rounding on a patient following splenectomy for idiopathic thrombocytopenia purpura. On postoperative day 2, a review of the laboratory studies is expected to reveal
- A. Increased MCV
- B. Increased Hgb
- C. Increased platelets
- D. Increased albumin
Correct Answer: B
Rationale: Step 1: Post-splenectomy, platelet count typically drops temporarily, leading to a risk of bleeding.
Step 2: To compensate, the body increases hemoglobin (Hgb) levels to maintain oxygen-carrying capacity.
Step 3: Therefore, on postoperative day 2, an increased Hgb level is expected.
Summary: A is incorrect because MCV is not typically affected in this scenario. C is incorrect because platelet count usually decreases post-splenectomy. D is incorrect as albumin levels are not directly impacted by splenectomy for ITP.
In which form of hypospadias should circumcision be deferred in order to preserve the prepuce for later surgical repair?
- A. Ventral displacement
- B. Proximal displacement
- C. Midscrotal hypospadias
- D. Meatus proximal to the corona
Correct Answer: A
Rationale: In ventral displacement hypospadias, circumcision should be deferred to preserve prepuce for later surgical repair as the prepuce is needed for reconstruction. The prepuce can be used as a tissue graft to correct the hypospadias. In proximal displacement, the urethral opening is closer to the scrotum, making prepuce preservation less critical. Midscrotal hypospadias and meatus proximal to the corona do not typically involve prepuce preservation for surgical repair.
Incidental antepartum haemorrhage is also referred to as
- A. Intraplacental haemorrhage
- B. Intrapartum haemorrhage
- C. Extraplacental haemorrhage
- D. Preterm haemorrhage
Correct Answer: C
Rationale: The correct answer is C: Extraplacental haemorrhage. Incidental antepartum haemorrhage refers to bleeding from a source other than the placenta, such as the cervix or vagina, before delivery. Intraplacental haemorrhage (choice A) refers to bleeding within the placenta itself, not outside it. Intrapartum haemorrhage (choice B) occurs during labor and delivery, not before. Preterm haemorrhage (choice D) is not a specific term used to describe antepartum bleeding. Therefore, the correct term for antepartum bleeding from a non-placental source is extraplacental haemorrhage.
