Parents of a school-age child with hemophilia ask the nurse, "Which sports are recommended for children with hemophilia?" Which sport should the nurse recommend?

Choice A rationale:

Morning sickness, which refers to nausea and vomiting during pregnancy, is a common symptom but not a definitive sign of pregnancy. It can also be caused by various other factors such as food poisoning or gastrointestinal issues. Therefore, it is not a positive sign of pregnancy.

Choice B rationale:

Quickening, which refers to the first fetal movements felt by the mother, is a subjective sign of pregnancy. It is not a definitive indication of pregnancy as it can be mistaken for other abdominal sensations. Quickening usually occurs between 18 to 22 weeks of gestation, making it a later sign and not an early positive sign of pregnancy.

Choice C rationale:

A positive pregnancy test, specifically a blood or urine test detecting human chorionic gonadotropin (hCG), is a reliable indicator of pregnancy. However, it is a biochemical sign and not a physical sign. It does not directly confirm the presence of the fetus or its well-being, making it less specific than auscultating the fetal heartbeat.

Choice D rationale:

Fetal heartbeat auscultated with Doppler/fetoscope is a positive sign of pregnancy. The healthcare provider can hear the fetal heartbeat using a Doppler ultrasound device or fetoscope, confirming the presence of a viable pregnancy. This sign is considered positive because it directly indicates the presence of a developing fetus, providing reassurance about the pregnancy status. Fetal heartbeat can usually be detected around 10 to 12 weeks of gestation.

Choice A rationale:

Ribbon-like stools are not characteristic of intussusception. Intussusception is a medical emergency where one portion of the intestine invaginates or telescopes into another. This condition can lead to intestinal obstruction and compromised blood flow, causing severe abdominal pain, vomiting, and bloody stools. The characteristic stool appearance associated with intussusception is "currant jelly" stools. These stools contain mucus, blood, and sloughed mucosal tissue, giving them a characteristic dark, sticky, and jelly-like appearance. This occurs due to the mixture of blood and mucus within the intestines.

Choice B rationale:

Hard stools positive for guaiac indicate the presence of occult blood in the stool, but this finding is not specific to intussusception. Occult blood in the stool can be a sign of gastrointestinal bleeding from various causes, such as ulcers, gastritis, or colorectal polyps. It is not a characteristic feature of intussusception.

Choice D rationale:

Loose, foul-smelling stools are nonspecific and can occur due to various gastrointestinal disorders, dietary issues, or infections. This description does not specifically indicate intussusception.
