Question 1 of 10
1. Question
All the following factors are attributing to the definition of clinically significant bradycardia except?
Correct
Clinically significant bradycardia occurs when the heart rate is slow and there are signs of systemic hypoperfusion (i.e., pallor, altered mental status, hypotension, and acidosis). Symptomatic bradycardia occurs most often in the setting of hypoxia but can also be caused by hypoglycemia, hypocalcemia, other electrolyte abnormalities, and intracranial hypertension.

4. Question
Anemia and reticulocytopenia that occur in the 2nd half of the infancy period are least likely due to?
Correct
The anemia of hemolytic disease of the newborn can have a protracted course, but this usually terminates spontaneously at 5-8 wk of age. Aplastic anemic crises, frequently caused by parvovirus B19 infections, might also additionally complicate diverse kinds of chronic hemolytic sickness.

Question 7 of 10
7. Question
Nearly all cervical carcinomas contain human papillomavirus (HPV). Which of the following types is never associated with such malignancy?
Correct
High-risk HPVs include types 16 and 18 but also types 31, 33, 35, 45, and 56, which are also commonly found in women without lesions. The low-risk HPVs, including 6 and 11 that are commonly found in genital warts, are almost never associated with malignancies.

Correct
Creatinine is affected by sex, height, muscle mass, bilirubin, and red blood cell hemolysis, while the concentration of blood urea nitrogen is affected by the state of hydration and nitrogen balance.
Incorrect

Question 10 of 10
10. Question
Thin basement membrane sickness TBMD is described via way of means of the presence of continual microscopic hematuria and isolated thinning of the GBM on electron microscopy, all the following are true except?
Correct
Rare cases of TBMD progress and such patients develop significant proteinuria, hypertension, or renal insufficiency. (Heterozygous mutations withinside the COL4A3 and COL4Agenes, which encode the α3 and α4 chains of kind IV collagen present in the GBM, result in TBMD while homozygous mutations in these same genes result in Autosomal recessive Alport syndrome).
