Correct Answer: D

Rationale: Hypospadias is a congenital condition where the urethral opening is located along the ventral surface of the penis, not the dorsal surface (Choice C) or absent (Choice A). This leads to the characteristic appearance of a ventrally displaced urethral meatus. The penis may appear normal in size but with the urethral opening positioned abnormally (Choice D), rather than being shorter than usual (Choice B). Therefore, the correct expectation for a newborn with hypospadias is that the urethral opening is along the ventral surface of the penis, making Choice D the correct answer.

Correct Answer: C

Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.

Correct Answer: C

Rationale: Avoiding gluten is not typically necessary for managing gastroesophageal reflux disease (GERD) in children. The correct dietary instruction for a 2-year-old with GERD would be to avoid high-fat foods. High-fat foods can relax the lower esophageal sphincter, leading to increased reflux symptoms. While spicy foods and dairy products may also trigger reflux in some individuals, the primary focus should be on avoiding high-fat foods due to their direct impact on the lower esophageal sphincter, which exacerbates GERD symptoms.

Correct Answer: B

Rationale: The priority intervention for a 3-month-old infant hospitalized with respiratory syncytial virus (RSV) is clustering care to conserve energy. Infants with RSV often struggle to breathe and require rest periods to recover. Clustering care involves organizing nursing activities to allow for rest intervals, reducing the infant's energy expenditure and aiding recovery. Administering antiviral agents is not the primary intervention for RSV since it is a viral infection, and antiviral medications may not be effective against RSV. While offering oral fluids is crucial for hydration, it may not be the priority when the infant is having respiratory difficulties. Providing an antitussive agent when necessary can help with coughing but is not the priority intervention for managing RSV in this scenario.

Correct Answer: D

Rationale: A respiratory rate of 50 breaths per minute in a 5-month-old infant is considered high and may indicate respiratory distress. Infants normally have a higher respiratory rate than older children and adults, but a rate of 50 breaths per minute is above the expected range. This finding warrants immediate attention as it may be indicative of an underlying respiratory issue or distress. Choice A (Temperature of 99.5°F) is within the normal range for body temperature and does not necessarily indicate a critical issue. Choice B (Blood pressure of 75/48 mm Hg) is not typically assessed in isolation for a 5-month-old infant during a routine examination, and the values provided are not indicative of a critical condition. Choice C (Heart rate of 100 beats per minute) is within the normal range for heart rate in infants and may not be a cause for immediate concern during a routine examination.
