A nurse is discussing growth with the parents of a 6-month-old infant who weighed 7 lbs at birth. Which statement best reflects the expected weight at this age?
A. "Your baby should weigh about 15 lbs by now."
"Your baby should weigh about 15 lbs by now" is correct. When discussing infant growth, nurses refer to standard pediatric growth milestones, which indicate that a healthy, full-term infant typically doubles their birth weight by 4–6 months and triples it by 12 months. Since this infant weighed 7 lbs at birth, the expected weight at 6 months would be approximately 14 lbs, making “about 15 lbs” an accurate and reassuring estimate. This reflects adequate nutrition and normal metabolic development.
B. "Your baby should weigh about 25 lbs by now."
"Your baby should weigh about 25 lbs by now" is incorrect because this weight is significantly above the expected range for a 6-month-old. A 25-lb infant at this age would be unusual and could suggest measurement error or a rare growth disorder.
C. "Your baby should weigh about 20 lbs by now."
"Your baby should weigh about 20 lbs by now" is incorrect because 20 lbs corresponds to an older infant, likely 12–15 months old, and is too high for a 6-month-old who weighed 7 lbs at birth.
D. "Your baby should weigh about 10 lbs by now."
"Your baby should weigh about 10 lbs by now" is incorrect because 10 lbs is less than double the birth weight. If a 6-month-old weighed only 10 lbs, it could indicate growth delay, malnutrition, or other underlying health concerns, requiring further assessment.

A school-age child with sickle cell anemia is admitted with a vaso-occlusive crisis. Which nursing action should the nurse prioritize to effectively manage this acute complication and prevent further morbidity?
A. Promote bed rest without additional pain interventions to allow natural resolution of the crisis.
Promote bed rest without additional pain interventions to allow natural resolution of the crisis is incorrect. While rest can help conserve energy, pain management is a priority in vaso-occlusive crises. Unmanaged pain can lead to stress-induced complications, prolonged hospital stays, and decreased oxygenation, which may worsen sickling.
B. Limit fluid intake to prevent fluid overload and minimize risk of pulmonary edema during the crisis.
Limit fluid intake to prevent fluid overload and minimize risk of pulmonary edema during the crisis is incorrect. Hydration is critical during a vaso-occlusive crisis because dehydration increases blood viscosity and promotes further sickling. Limiting fluids can exacerbate the crisis rather than help it.
C. Administer prescribed opioids promptly and encourage oral hydration as tolerated to manage pain and reduce sickling episodes.
Administer prescribed opioids promptly and encourage oral hydration as tolerated to manage pain and reduce sickling episodes is correct. Prompt administration of opioids (e.g., morphine or hydromorphone) addresses the severe pain associated with vaso-occlusive crises, while hydration helps maintain blood volume and decreases the likelihood of additional sickling. These interventions are central to reducing morbidity and preventing complications such as organ damage or prolonged hypoxia.
D. Delay opioid administration to assess the child's pain threshold and avoid potential opioid dependence.
Delay opioid administration to assess the child's pain threshold and avoid potential opioid dependence is incorrect. Pain should be treated promptly in vaso-occlusive crises. Delaying analgesia increases suffering, can worsen hypoxia, and may lead to more severe complications. Concerns about long-term opioid dependence are secondary to immediate pain control and patient safety.

A newborn is suspected of having esophageal atresia with tracheoesophageal fistula (TEF). Which clinical finding would most strongly support this diagnosis?
A. Excessive oral secretions, coughing, and cyanosis during feeding
Excessive oral secretions, coughing, and cyanosis during feeding is correct. These are classic signs of esophageal atresia with tracheoesophageal fistula (TEF). TEF results in an abnormal connection between the trachea and esophagus, causing ingested fluids to enter the airway. This leads to choking, coughing, cyanosis, and excessive drooling, especially during feeding. Early recognition is critical to prevent aspiration and respiratory complications.
B. Poor suck reflex and hypotonia
Poor suck reflex and hypotonia is incorrect because these findings are associated with neurologic or metabolic disorders, not TEF. While feeding difficulties may occur, they do not specifically indicate a fistula between the trachea and esophagus.
C. Projectile vomiting with blood-tinged emesis
Projectile vomiting with blood-tinged emesis is incorrect because this is more characteristic of pyloric stenosis or upper gastrointestinal bleeding, not TEF. TEF primarily affects swallowing and airway protection, not gastric emptying.
D. Bilious vomiting with abdominal distension
Bilious vomiting with abdominal distension is incorrect because these signs suggest intestinal obstruction, such as malrotation or intestinal atresia, rather than TEF.

A 24-year-old pregnant woman asks the nurse if it is safe to drink alcohol during pregnancy. Which of the following is the most appropriate response?
A. Small amounts of alcohol are safe during the second trimester."
"Small amounts of alcohol are safe during the second trimester." is incorrect because no amount of alcohol is considered safe during pregnancy. Even small amounts can affect fetal development and increase the risk of fetal alcohol spectrum disorders (FASD).
B. "Alcohol is only harmful in the first trimester."
"Alcohol is only harmful in the first trimester." is incorrect because alcohol exposure can be harmful at any stage of pregnancy, not just the first trimester. While organogenesis occurs early, alcohol can still affect fetal growth, brain development, and neurobehavioral outcomes throughout pregnancy.
C. "Alcohol should be avoided completely during pregnancy."
"Alcohol should be avoided completely during pregnancy." is correct. The safest recommendation is complete abstinence from alcohol. This approach eliminates the risk of alcohol-related complications and supports optimal fetal development. Health authorities, including the CDC and ACOG, advise that no level of alcohol is safe during pregnancy.
D. "Beer is safer than hard liquor while pregnant."
"Beer is safer than hard liquor while pregnant." is incorrect because all types of alcoholic beverages pose a risk to the developing fetus, regardless of alcohol content or type. There is no safe form of alcohol during pregnancy.
