A nurse is caring for a client who reports that he has a headache and vertigo after turning on his furnace for the first time this season.
The nurse suspect which of the following?
Carbon monoxide poisoning
Meniere’s disease
Migraine
Benign paroxysmal positional vertigo.
The Correct Answer is A
Carbon monoxide poisoning.
This is because the client reports having a headache and vertigo after turning on his furnace for the first time this season. These are common symptoms of carbon monoxide poisoning, which can occur when carbon monoxide, a colorless and odorless gas, builds up in the blood due to exposure to combustion fumes.
The furnace may have been a source of carbon monoxide if it was not well vented or maintained.
The other statements are wrong because:
Meniere’s disease is a disorder of the inner ear that causes vertigo, hearing loss, tinnitus and ear fullness. It is not related to carbon monoxide exposure or furnace use.
Migraine is a type of headache that causes throbbing pain, nausea, sensitivity to light and sound, and sometimes visual disturbances. It is not caused by carbon monoxide exposure or furnace use, but by genetic and environmental factors.
Benign paroxysmal positional vertigo (BPPV) is a condition that causes brief episodes of vertigo triggered by changes in head position. It is caused by tiny crystals in the inner ear that become dislodged and stimulate the balance sensors. It is not related to carbon monoxide exposure or furnace use.

Correct Answer is B
Explanation
Bulging fontanelles.Bulging fontanelles can be a sign of increased intracranial pressure or intracranial and extracranial tumors.This is a potential problem for the newborn’s brain and health and should be evaluated by imaging studies.
Choice A is wrong because sunken fontanelles are usually a sign of dehydration, which is not a problem with the fontanelles themselves, but with the fluid balance of the newborn.
Choice C is wrong because a diamond-shaped anterior fontanelle is normal for a newborn.The anterior fontanelle is the largest and most important for clinical evaluation.It has an average size of 2.1 cm and a median time of closure of 13.8 months.
Choice D is wrong because a triangular posterior fontanelle is also normal for a newborn.The posterior fontanelle is smaller than the anterior one and normally closes by 8 weeks.
Correct Answer is D
Explanation
Plagiocephaly.
This condition is also known as flat head syndrome and it occurs when an infant’s head shape becomes flattened due to external pressure.It can be caused by molding during delivery or by sleeping in the same position for a long time.
Choice A is wrong because caput succedaneum is a swelling of the scalp that results from pressure on the baby’s head during childbirth.It does not affect the shape of the head, but only causes temporary puffiness and bruising.
Choice B is wrong because cephalohematoma is bleeding under the scalp that occurs when blood vessels are damaged during delivery.It causes a firm lump on one side of the head that does not cross the suture lines.
Choice C is wrong because craniosynostosis is a condition where one or more of the sutures (joints) between the skull bones close prematurely, preventing normal growth of the head.It can cause an abnormal head shape, but it is not related to molding during delivery.
