What is the primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux?
Prevent reflux.
Reduce gastric acid production.
Prevent hematemesis.
Increase gastric acid production.
The Correct Answer is B
The correct answer is choice B. Reduce gastric acid production.
Choice A rationale:
Preventing reflux is not the primary purpose of prescribing a histamine receptor antagonist. Histamine receptor antagonists work by reducing gastric acid production, which in turn can help alleviate symptoms of gastroesophageal reflux disease (GERD). They do not directly prevent the physical reflux of stomach contents into the esophagus.
Choice B rationale:
The primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux is to reduce gastric acid production. Histamine stimulates acid secretion in the stomach, and these medications (e.g., ranitidine, famotidine) block histamine receptors on stomach cells, leading to decreased acid secretion. This helps reduce the acidity of stomach contents that could contribute to esophageal irritation in GERD.
Choice C rationale:
Preventing hematemesis (vomiting blood) is not a primary action of histamine receptor antagonists. While reducing gastric acid production might indirectly help prevent complications such as bleeding due to irritation and inflammation of the esophagus, it's not the main purpose of these medications.
Choice D rationale:
Increasing gastric acid production is the opposite of the intended effect of histamine receptor antagonists. These medications are specifically used to decrease gastric acid production and provide relief from conditions where excess acid is causing problems, such as GERD.

Correct Answer is ["A","E"]
Explanation
The correct answers are choices A and E: Institute cluster care to encourage adequate rest and Place on noninvasive oxygen monitoring.
Choice A rationale:
Institute cluster care to encourage adequate rest. This is a correct choice. Cluster care involves grouping nursing interventions together to minimize disruptions to the child's rest. Adequate rest is crucial for the healing process in infants with respiratory syncytial virus (RSV) bronchiolitis.
Choice B rationale:
Administer cough syrup. This choice is incorrect for RSV bronchiolitis. Cough syrup is not recommended for infants with bronchiolitis. RSV primarily affects the lower respiratory tract and can cause airway inflammation, making cough syrup potentially ineffective and unnecessary.
Choice C rationale:
Administer antibiotics. This choice is incorrect for RSV bronchiolitis. RSV is a viral infection, and antibiotics are ineffective against viruses. Antibiotics should only be used when there is a bacterial infection or a clear indication.
Choice D rationale:
Encourage infant to drink 8 ounces of formula every 4 hours. This choice is not the best approach for managing RSV bronchiolitis. Infants with RSV may experience decreased appetite due to respiratory distress. Smaller, more frequent feedings are often recommended to prevent overfeeding and aspiration.
Choice E rationale:
Place on noninvasive oxygen monitoring. This is a correct choice. RSV bronchiolitis can cause respiratory distress and compromise oxygenation. Noninvasive oxygen monitoring helps assess the child's oxygen levels and aids in determining the need for supplemental oxygen therapy.
Correct Answer is ["A","D","E"]
Explanation
The correct answers are choices A, D, and E. Unequal waist angles, an uneven hemline, and asymmetry of the shoulders.
Choice A rationale:
Unequal waist angles can be an indication of scoliosis, a condition characterized by abnormal lateral curvature of the spine. When the spine curves, it can cause one side of the waist to appear higher than the other, leading to unequal waist angles. This is a key physical finding in scoliosis assessment.
Choice B rationale:
Complaints of a sore back are a non-specific symptom and may not directly indicate scoliosis. While scoliosis can sometimes cause discomfort or pain, it's not the primary assessment finding that the nurse should expect to observe.
Choice C rationale:
Inability to bend at the waist is not a typical assessment finding of scoliosis. Scoliosis primarily involves the lateral curvature of the spine, which can lead to visible asymmetry and postural changes rather than restrictions in bending.
Choice D rationale:
An uneven hemline can be a sign of scoliosis. When the spine curves, it can cause the hips and shoulders to become misaligned, leading to changes in the alignment of clothing and accessories, such as an uneven hemline.
Choice E rationale:
Asymmetry of the shoulders is a common manifestation of scoliosis. One shoulder may appear higher than the other due to the lateral curvature of the spine. This asymmetry is often more noticeable when the child is viewed from behind.
