The most common complication of respiratory distress syndrome is

Correct Answer: B

Rationale: The correct answer is B: Pneumothorax. Respiratory distress syndrome is characterized by difficulty breathing due to immature lungs in premature infants. Pneumothorax, a condition where air leaks into the chest cavity, is a common complication as the fragile lungs are prone to air leaks. Cerebral palsy (A), epilepsy (C), and fractured ribs (D) are not direct complications of respiratory distress syndrome. Pneumothorax is the most likely and common complication due to the fragility of the premature infant's lungs.

Correct Answer: A

Rationale: The correct answer is A: Ventral displacement. In ventral displacement hypospadias, the urethral opening is located on the underside of the penis, making it necessary to defer circumcision to preserve the prepuce for later surgical repair. Preserving the prepuce in this case is important for reconstructive surgery to correct the hypospadias. Choices B, C, and D do not require deferring circumcision as the location of the urethral opening does not impact the need for prepuce preservation for future surgical repair.

Correct Answer: B

Rationale: The correct answer is B - Culture and level of education. Culture influences beliefs about pain and coping mechanisms. Education can affect understanding of pain and pain management techniques. Labor preparedness and fatigue (A) may impact pain perception but are not as influential. Age (C) alone does not determine pain perception. Number of deliveries and anxiety (D) can play a role but are not as significant as culture and education.

Correct Answer: D

Rationale: The correct answer is D: Portal hypertension. In myelodysplastic syndromes, splenectomy is indicated primarily for portal hypertension due to extramedullary hematopoiesjson in the spleen, leading to increased blood flow and pressure in the portal vein. This can alleviate symptoms such as ascites and variceal bleeding. Choices A, B, and C are incorrect as major hemolysis, massive splenomegaly, and sustained leukocyte elevation are not primary indications for splenectomy in myelodysplastic syndromes.

Correct Answer: C

Rationale: The correct answer is C: Wrinkled, peeling skin. Post-maturity syndrome occurs when a pregnancy extends beyond 42 weeks, causing the baby to lose the protective layer of vernix caseosa, leading to dry, peeling skin. Closed eyes and being unusually alert (A) are not specific to post-maturity syndrome. Long, frail fingernails (B) are not a typical characteristic of post-maturity. Excess vernix caseosa (D) is actually a characteristic of a premature baby, not a post-mature one.

Correct Answer: A

Rationale: Grade 1 cardiac disease refers to early-stage or mild heart conditions that are not yet severe. Choice A, "Organic disease," is the correct answer as it encompasses a broad category of structural heart abnormalities. Mitral stenosis (B) and ventricular failure (C) are specific conditions that can be present in cardiac disease but do not represent the general term for grade 1. Vascular disease (D) primarily refers to conditions affecting blood vessels, not the heart itself. In summary, choice A is correct because it is a comprehensive term that includes various structural heart abnormalities typically found in grade 1 cardiac disease, while the other choices are either too specific or unrelated to the concept of grade 1 cardiac disease.

Correct Answer: B

Rationale: The correct answer is B: Pneumothorax. Respiratory distress syndrome is characterized by difficulty breathing due to immature lungs in premature infants. Pneumothorax, a condition where air leaks into the chest cavity, is a common complication as the fragile lungs are prone to air leaks. Cerebral palsy (A), epilepsy (C), and fractured ribs (D) are not direct complications of respiratory distress syndrome. Pneumothorax is the most likely and common complication due to the fragility of the premature infant's lungs.

Correct Answer: A

Rationale: The correct answer is A: Frank breech, complete breech, footling breech. In a frank breech presentation, the baby's buttocks are aimed at the birth canal with legs flexed at the hips and extended at the knees. In a complete breech presentation, the baby's buttocks are aimed at the birth canal with legs flexed at the hips and knees. In a footling breech presentation, one or both of the baby's feet are positioned to come out first. These are the three main types of breech presentations. Choices B, C, and D do not accurately describe the different types of breech presentations, making them incorrect.

Correct Answer: A

Rationale: The correct answer is A: Increased MCV. Following splenectomy, there is a compensatory increase in red blood cell production, leading to an increase in Mean Corpuscular Volume (MCV) due to the release of larger, younger red blood cells into circulation. This is known as stress erythropoiesis. Summary: B: Increased Hgb - Hgb levels may not necessarily increase post-splenectomy as it depends on factors such as bleeding or hydration status. C: Increased platelets - Platelet count is not expected to increase immediately post-splenectomy. D: Increased albumin - Albumin levels are not directly influenced by splenectomy for idiopathic thrombocytopenia purpura.
