Which description of stool is characteristic of intussusception?
Loose, foul-smelling stools.
Ribbon-like stools.
Hard stools positive for guaiac.
"Currant jelly" stools.
The Correct Answer is D
The correct answer is choice D. "Currant jelly" stools.
Choice A rationale:
Loose, foul-smelling stools are not characteristic of intussusception. Intussusception is a condition in which a part of the intestine invaginates into another part, causing obstruction. This obstruction often leads to "currant jelly" stools, which are composed of mucus, blood, and sloughed intestinal tissue. Loose stools might be associated with other gastrointestinal issues but are not a hallmark of intussusception.
Choice B rationale:
Ribbon-like stools are characteristic of intussusception. When a section of the intestine telescopes into another section, it can cause the stool to be squeezed into a ribbon-like shape as it passes through the narrowed portion. This description aligns with the pathophysiology of intussusception.
Choice C rationale:
Hard stools positive for guaiac indicate the presence of blood in the stool, but this finding is not specific to intussusception. Guaiac testing detects occult blood, which could be present in various gastrointestinal conditions, including bleeding ulcers or diverticulitis, and not exclusively in intussusception.
Choice D rationale:
"Currant jelly" stools are characteristic of intussusception. As mentioned earlier, these stools are the result of the obstruction and subsequent damage to the intestinal lining, leading to the presence of blood, mucus, and sloughed tissue. This description is a classic sign of intussusception and should raise suspicion for this condition.

Correct Answer is B
Explanation
The correct answer is choice B: Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Choice A rationale:
Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy. This choice is incorrect because it includes "aortic hypertrophy" and "left ventricular hypertrophy," which are not components of the tetralogy of Fallot. Aortic hypertrophy is not a recognized structural defect in tetralogy of Fallot, and left ventricular hypertrophy is not a characteristic feature of this congenital heart condition.
Choice B rationale:
Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This is the correct choice. Tetralogy of Fallot is characterized by four specific structural defects: pulmonic stenosis (narrowing of the pulmonary valve), ventricular septal defect (hole between the right and left ventricles), overriding aorta (aorta positioned over the ventricular septal defect, receiving blood from both ventricles), and right ventricular hypertrophy (enlargement of the right ventricle due to increased workload).
Choice C rationale:
Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This choice is incorrect because it includes "aortic stenosis," which is not part of the tetralogy of Fallot. In tetralogy of Fallot, the stenosis occurs at the pulmonary valve, not the aortic valve.
Choice D rationale:
Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy. This choice is incorrect. While "overriding aorta" is present in tetralogy of Fallot, "atrial septal defect" and "left ventricular hypertrophy" are not part of this condition. Atrial septal defects involve a hole between the two atria, not the ventricles, and left ventricular hypertrophy is not typically seen in tetralogy of Fallot.
Correct Answer is B
Explanation
The correct answer is choice b. Grasp the tick by the body to remove.
Choice A rationale:
Cleansing the wound with soap and water is a correct action. It helps to prevent infection after the tick has been removed.
Choice B rationale:
Grasping the tick by the body is incorrect. The proper method is to use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible and pull upward with steady, even pressure. Grasping the tick by the body can cause the mouth-parts to break off and remain in the skin, increasing the risk of infection.
Choice C rationale:
Leaving the tick in place and seeking emergency medical treatment is not recommended. The tick should be removed as soon as possible to reduce the risk of disease transmission.
Choice D rationale:
Avoiding touching the tick with bare hands is correct. Using gloves or tissue to handle the tick helps prevent the transmission of pathogens.
