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 ["B","C"]
Explanation
The child’s care should include adequate hydration and pain management. The management of an acute event of a vaso-occlusive crisis is the use of potent analgesics (opioids), rehydration with normal saline or Ringer’s lactate, treatment of malaria (whether symptomatic or not) using artemisinin combination therapy, and the use of oxygen via face mask, especially for acute chest syndrome.
Choice A is wrong because correction of acidosis is not a specific intervention for the vaso- occlusive crisis.
Acidosis may occur as a complication of sickle cell disease, but it is not the primary cause of the crisis.
Choice D is wrong because the administration of heparin is not recommended for the vaso-occlusive crisis.
Heparin is an anticoagulant that may increase the risk of bleeding and does not prevent or treat the sickling process.
Normal ranges for hemoglobin are 11.5 to 15.5 g/dl for children after 2 years of age.
Normal ranges for reticulocyte count are 0.5% to 1.5% for adults and 0.5% to 2.5% for children.
Correct Answer is ["B","D"]
Explanation
Sleepiness or fatigue and puffiness around the eyes are symptoms associated with hypothyroidism. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, which regulate the body’s metabolism and energy levels.
Choice A is wrong because weight loss is more likely to occur in hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormones.
Choice C is wrong because diarrhea is also more likely to occur in hyperthyroidism, as the excess thyroid hormones speed up the digestive system.
Choice E is wrong because limited hair growth is not a specific symptom of hypothyroidism. Hair loss or thinning may occur in both hypothyroidism and hyperthyroidism, depending on the severity and duration of the condition.
Normal ranges for thyroid hormones are:
- TSH: 0.4 to 4.0 mIU/L
- T3: 100 to 200 ng/dL
- T4: 4.5 to 11.2 mcg/dL
