A 3-month-old is admitted with severe diarrhea. Yesterday, the infant weighed 11 pounds (5 kg). Today, this infant weighs 9 pounds, 8 ounces (4.3 kg). Based on this information, the nurse documents that the infant has:
Failure to thrive.
Malabsorption syndrome.
Severe dehydration.
Risk for fluid volume deficit.
The Correct Answer is C
Choice A rationale
Failure to thrive is a condition where a child does not gain weight or grow as expected. While severe diarrhea can contribute to failure to thrive, the immediate concern in this scenario is the significant weight loss indicating severe dehydration.
Choice B rationale
Malabsorption syndrome involves the inability to absorb nutrients properly, leading to malnutrition and weight loss. However, the acute weight loss in this case is more indicative of severe dehydration.
Choice C rationale
Severe dehydration is characterized by significant fluid loss, which can be life-threatening in infants. The weight loss from 11 pounds to 9 pounds, 8 ounces indicates a substantial fluid loss, pointing to severe dehydration.
Choice D rationale
Risk for fluid volume deficit is a potential diagnosis, but the significant weight loss and clinical presentation indicate that the infant is already experiencing severe dehydration.

Correct Answer is A
Explanation
Choice A rationale
Tugging on the affected ear lobe is a common sign of otitis media in children. This behavior is often observed because the child is experiencing discomfort or pain in the ear, and tugging or pulling on the ear lobe is a way to express or alleviate that discomfort.
Choice B rationale
Erythema and edema of the affected ear are not typical findings in otitis media. These symptoms are more commonly associated with external ear infections, such as otitis externa.
Choice C rationale
Pain when manipulating the affected ear lobe is more indicative of otitis externa rather than otitis media. Otitis media involves the middle ear, and manipulation of the ear lobe does not typically cause pain.
Choice D rationale
Clear drainage from the affected ear is not a typical finding in otitis media. If there is drainage, it is usually purulent (pus-like) and indicates a more severe infection or a ruptured eardrum.
Correct Answer is C
Explanation
Choice A rationale
The conjunctivae, the mucous membranes that cover the front of the eye and line the inside of the eyelids, can show signs of cyanosis. However, they are not the most reliable indicator of central cyanosis. Central cyanosis is best observed in areas with a rich blood supply and thin skin, where the bluish discoloration due to low oxygen levels in the blood is more apparent.
Choice B rationale
The soles of the feet are not a reliable indicator of central cyanosis. Peripheral cyanosis, which affects the extremities, can occur due to poor circulation or cold temperatures and does not necessarily indicate central cyanosis. Central cyanosis is more accurately assessed in areas with a high concentration of blood vessels and thin skin.
Choice C rationale
The oral mucosa, including the lips and tongue, is the most reliable indicator of central cyanosis. This area has a rich blood supply and thin skin, making it easier to observe the bluish discoloration caused by low oxygen levels in the blood. Central cyanosis is a sign of significant hypoxemia and requires prompt medical attention.
Choice D rationale
The ear lobes are not the most reliable indicator of central cyanosis. While they can show signs of cyanosis, they are not as accurate as the oral mucosa. The ear lobes may be affected by peripheral cyanosis, which can occur due to factors like cold temperatures or poor circulation, rather than central cyanosis.
