A premature infant with respiratory distress syndrome receives artificial surfactant. How would the nurse explain surfactant therapy to the parents?
“Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.”.
“The drug keeps your baby from requiring too much sedation.”.
“Surfactant is used to reduce episodes of periodic apnea.”.
“Your baby needs this medication to fight a possible respiratory tract infection.”.
The Correct Answer is A
choice A. Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.
Surfactant is a substance that coats the inner surface of the alveoli, the tiny air sacs in the lungs.
It reduces the surface tension of the alveoli and prevents them from collapsing during exhalation.
Premature infants often lack enough surfactant, which leads to respiratory distress syndrome (RDS).
Artificial surfactant is given to these infants to help them breathe more easily. Choice B is wrong because surfactant has nothing to do with sedation.
Sedation is a state of reduced consciousness induced by drugs. Surfactant does not affect the level of consciousness of the infant.
Choice C is wrong because surfactant is not used to reduce episodes of periodic apnea.
Periodic apnea is a condition where the infant stops breathing for a short time, usually due to immature brainstem function.
Surfactant does not affect the brainstem or the control of breathing.
Choice D is wrong because surfactant is not used to fight a possible respiratory tract infection. Surfactant does not have any antibacterial or antiviral properties.
Surfactant is used to treat RDS, which is caused by a lack of surfactant, not by an infection.

Correct Answer is C
Explanation
Verbalizing the importance of monitoring for medication side effects.
Graves’ disease is an autoimmune disorder that causes hyperthyroidism, which means the thyroid gland produces too much thyroid hormone. This can lead to symptoms such as weight loss, increased appetite, nervousness, irritability, insomnia, heat intolerance, and palpitations. The medication methimazole is used to treat Graves’ disease by blocking the synthesis of thyroid hormone. However, methimazole can also cause serious side effects such as liver damage, agranulocytosis (low white blood cell count), and allergic reactions.
Therefore, the priority nursing goal for a 14 year old diagnosed with Graves’ disease is to verbalize the importance of monitoring for medication side effects and reporting them to the health care provider.
Choice A is wrong because relieving constipation is not a priority goal for Graves’ disease. Constipation is more likely to occur in hypothyroidism, which is the opposite of hyperthyroidism.
Choice B is wrong because allowing the adolescent to make decisions about whether or not to take medication is not a priority goal for Graves’ disease. While it is important to respect the adolescent’s autonomy and involve them in their care plan, they also need to understand the risks and benefits of taking medication and the consequences of not taking it.
Choice D is wrong because developing alternative educational goals is not a priority goal for Graves’ disease. Graves’ disease can affect the academic performance of adolescents due to cognitive and emotional changes caused by hyperthyroidism.
However, this does not mean that they need to change their educational goals. They may need extra support and accommodations from their teachers and parents to cope with their condition and achieve their potential.
Correct Answer is B
Explanation
Measles (rubeola) is a communicable disease that is characterized by Koplik’s spots, which are clustered, white lesions on the buccal mucosa opposite the lower molars. They appear two to three days before the measles rash and are pathognomonic for measles.
Choice A is wrong because rubella is a different viral infection that causes a mild rash and fever, but does not have Koplik’s spots.
Choice C is wrong because chickenpox (varicella) is caused by the varicella-zoster virus and produces fluid-filled blisters on the skin, not white spots in the mouth.
Choice D is wrong because exanthema subitum (roseola) is caused by the human herpesvirus 6 or 7 and causes a high fever followed by a pink rash on the trunk and neck, but no oral lesions.
