Correct Answer: A

Rationale: Using tracheostomy covers when outdoors is essential to protect the tracheostomy from dust and debris, reducing the risk of infection. Tracheostomy covers help maintain cleanliness and prevent foreign particles from entering the stoma. Choice B is incorrect because cleaning the tracheostomy with alcohol can be too harsh and drying for the skin surrounding the stoma, leading to skin irritation. Choice C is incorrect as tracheostomy tubes are typically replaced only when clinically indicated or as per the healthcare provider's instructions, not routinely every week, to prevent unnecessary risks and complications. Choice D is incorrect as covering the tracheostomy with a wet cloth when sleeping can create a moist environment ideal for bacterial growth, increasing the risk of infection and skin breakdown. It is important to keep the tracheostomy site clean, dry, and protected to maintain optimal hygiene and prevent complications.

Correct Answer: B

Rationale: The correct answer is B: Increased urine output. In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), leading to the excretion of large amounts of dilute urine. Reporting increased urine output is crucial as it is a hallmark sign of diabetes insipidus. Weight gain (choice A) is not typically associated with diabetes insipidus; instead, clients may experience weight loss due to fluid loss. Low blood pressure (choice C) can be a complication of diabetes insipidus due to dehydration from excessive urination, but the priority finding to report is the increased urine output. Thirst (choice D) is a common symptom of diabetes insipidus due to the body's attempt to compensate for fluid loss, but it is not the most critical finding to report.

Correct Answer: A

Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.

Correct Answer: D

Rationale: The correct answer is D because there is no need to wait 72 hours before allowing the child to stand. The synthetic cast does not affect weight-bearing capacity, and standing can be done as tolerated. Choice A is incorrect because keeping the cast covered can lead to damage or accidents. Choice B is acceptable as applying an ice pack can help relieve itching. Choice C is also correct as elevating the cast on pillows can help reduce swelling and promote comfort during rest.

Correct Answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.
