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.

Correct Answer: D

Rationale: A respiratory rate of 50 breaths per minute in a 5-month-old infant is higher than the expected range and may indicate respiratory distress. This finding is concerning and should prompt the nurse to notify the health care provider for further evaluation and intervention. A temperature of 99.5°F, blood pressure of 75/48 mm Hg, and heart rate of 100 beats per minute are within normal ranges for a 5-month-old infant. Elevated temperature may indicate a mild fever, which can be monitored. A blood pressure of 75/48 mm Hg is within the normal range for infants. A heart rate of 100 beats per minute is also within the expected range for a 5-month-old infant and does not typically require immediate notification of the health care provider.

Correct Answer: A

Rationale: The correct answer is monitoring for hypertension. Acute glomerulonephritis involves inflammation of the kidney's glomeruli, potentially leading to impaired kidney function and elevated blood pressure. Monitoring for hypertension is crucial as it is a common complication of this condition. Providing pain relief (choice B) may be necessary for comfort but is not the priority. While fluid restriction (choice C) is important in some kidney conditions, in acute glomerulonephritis, maintaining adequate hydration to support kidney function is typically recommended. Encouraging fluid intake (choice D) may exacerbate fluid overload, making it an inappropriate intervention in this scenario.

Correct Answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less space for swelling within the skull compared to adults, making them more prone to experiencing symptoms like nausea and vomiting. Altered mental status and changes in pupillary reaction can also occur in both children and adults following head trauma, but they are not specifically more common in children. Tachycardia and diaphoresis are generally signs of autonomic nervous system activation and may occur in both children and adults, but they are not typically more common in children compared to adults following head trauma.

Correct Answer: B

Rationale: Cellulitis is characterized by warmth at the site of skin disruption, indicating an infection. The correct answer is choice B. Choice A, 'Red, raised hair follicles,' is more indicative of folliculitis rather than cellulitis. Choice C, 'Papules progressing to vesicles,' is more characteristic of conditions like chickenpox, not cellulitis. Choice D, 'Honey-colored exudate,' is typical of wound infections with bacteria like Staphylococcus aureus, not cellulitis.
