Rationale: The correct answer is A: 8 to 12 months of age. Surgical correction for a cleft palate is typically performed around this age to optimize speech development and prevent feeding difficulties. Options B, C, and D suggest later ages for surgery, which may lead to speech and feeding issues due to the delay in correction.

Correct Answer: A

Rationale: The correct answer is A: Safe staffing. Safe staffing is a critical issue in nursing today due to its impact on patient outcomes and nurse well-being. While low workloads (choice B) may seem beneficial, they can also indicate understaffing, leading to burnout and compromising patient care. Increasing professional autonomy (choice C) is generally viewed positively as it empowers nurses, and improving salaries (choice D) is important but may not directly address patient safety concerns related to staffing levels.

Correct Answer: D

Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.

Correct Answer: B

Rationale: The expected date of delivery is calculated by adding 9 months and 7 days to the last menstrual period. For April 20th, the expected date is January 27th. Therefore, the correct answer is B. Choice A, January 20th, is incorrect as it does not account for the additional 7 days. Choice C, January 29th, and Choice D, January 31st, are also incorrect as they do not consider the standard calculation method for estimating the due date.

Correct Answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.
