Nurses can prevent evaporative heat loss in the newborn by:
Drying the baby after birth and wrapping the baby in a dry blanket.
Keeping the baby out of drafts and away from air conditioners.
Placing the baby away from the outside wall and the windows.
Warming the stethoscope and the nurse’s hands before touching the baby.
The Correct Answer is A
Drying the baby after birth and wrapping the baby in a dry blanket
This prevents evaporative heat loss, which occurs when water on the skin surface evaporates and cools the skin. Evaporative heat loss is especially significant in newborns because they are wet at birth and have a large surface area relative to their body mass.
Choice B is wrong because it addresses convective heat loss, which occurs when air currents blow over the skin and carry away heat.
Convective heat loss can be prevented by keeping the baby out of drafts and away from air conditioners.
Choice C is wrong because it addresses radiant heat loss, which occurs when heat radiates from the skin to cooler objects in the environment.
Radiant heat loss can be prevented by placing the baby away from the outside wall and the windows.
Choice D is wrong because it addresses conductive heat loss, which occurs when heat transfers from the skin to cooler objects in contact with the skin.
Conductive heat loss can be prevented by warming the stethoscope and the nurse’s hands before touching the baby.
Normal body temperature for a newborn is 36.5°C to 37.5°C (97.7°F to 99.5°F).

Correct Answer is A
Explanation
This is a normal respiratory change in pregnancy caused by elevated levels of estrogen. Estrogen increases blood flow and causes the nasal mucosa to swell, leading to congestion and nosebleeds. This condition is called pregnancy rhinitis and affects up to 20% of pregnant women.
Choice B is wrong because this is not an abnormal cardiovascular change, and the nosebleeds are not an ominous sign. They are usually harmless and do not affect the pregnancy outcome.
Choice C is wrong because there is no evidence that the woman is a victim of domestic violence.
This is a serious accusation that should not be made without proper assessment and screening.
Choice D is wrong because there is no indication that the woman has been using cocaine intranasally. Cocaine use can cause nasal damage and bleeding, but it can also have other signs and symptoms such as agitation, euphoria, dilated pupils, increased heart rate and blood pressure, and risk of miscarriage or preterm labor.
Correct Answer is B
Explanation
Swimming is one of the best sports for people with hemophilia because it strengthens the muscles without putting stress on the joints. Swimming is also recommended by most sports physicians and hematologists for patients with hemophilia.
Choice A is wrong because soccer is a contact sport that can cause injuries and bleeding episodes in people with hemophilia. Soccer is not recommended by most sports physicians or hematologists for patients with hemophilia.
Choice C is wrong because basketball is also a contact sport that can lead to injuries and bleeding episodes in people with hemophilia. Basketball may be safe for young children, but the risk increases with the intensity of the game.
Choice D is wrong because football is a collision sport that can cause severe injuries and bleeding episodes in people with hemophilia. Football is not recommended by most sports physicians or hematologists for patients with hemophilia.
Normal ranges for hemophilia are:
- Mild hemophilia: 5% to 40% of normal clotting factor
- Moderate hemophilia: 1% to 5% of normal clotting factor
Severe hemophilia: less than 1% of normal clotting factor
