A nurse is caring for a patient with diabetes mellitus who is prescribed regular insulin via a sliding scale. After administering the correct dose at 0715, by which of the following times should the nurse ensure the patient receives breakfast?
0720.
0815.
0745.
0730.
The Correct Answer is C
0745.. Regular insulin has an onset of action of 30 to 60 minutes, a peak effect of 2 to 4 hours, and a duration of action of 6 to 8 hours. Therefore, the patient should receive breakfast within 30 minutes of receiving the insulin injection to prevent hypoglycemia.
Choice A. 0720 is incorrect because it is too soon after the injection and the insulin may not have reached its onset of action yet.
Choice B. 0815 is incorrect because it is too late after the injection and the insulin may have reached its peak effect by then, increasing the risk of hypoglycemia.
Choice D. 0730. is incorrect because it is less than 30 minutes after the injection and the insulin may be approaching its peak effect.

Correct Answer is B
Explanation
Answer: B. 6-year-old child who has a spiral fracture of the tibia and fibula, which reportedly occurred while riding a bicycle.
Rationale:
A) 3-year-old toddler with scalding burns over the face and chest reportedly sustained when the child pulled on a tablecloth, spilling a cup of tea on himself:
Scalding burns in young children can be accidental, especially if the burns are consistent with typical patterns seen in such accidents. However, burns covering a large area, especially on the face and chest, may warrant further investigation to rule out abuse, particularly if the explanation seems inconsistent with the injury.
B) 6-year-old child who has a spiral fracture of the tibia and fibula, which reportedly occurred while riding a bicycle:
A spiral fracture is often associated with a twisting or rotational force, which is less common in typical bicycle accidents. Spiral fractures in children can be indicative of physical abuse, particularly if the explanation for the injury does not fit the typical mechanisms of injury associated with the reported activity. This type of fracture should prompt a thorough evaluation for possible abuse.
C) 14-month-old toddler who is reportedly learning to walk and has several bruises on bony prominences of the lower legs and elbows:
Bruises on bony prominences are common in toddlers who are learning to walk and are prone to minor falls. This pattern of bruising is usually consistent with typical developmental activities rather than abuse. However, repeated or severe bruising should still be evaluated carefully.
D) 9-month-old infant who sustained near drowning when he reportedly climbed into the tub and turned on the water:
While near drowning in an infant is a serious concern, it is less likely to be related to physical abuse if the explanation involves an accidental event. A thorough assessment is necessary to ensure safety and prevent further incidents, but the described scenario is not as indicative of abuse as a spiral fracture.
Correct Answer is B
Explanation
The nurse should walk with the client at a gradually slowing pace when caring for a client with a generalized anxiety disorder who is rapidly pacing the corridors of the unit. This intervention provides the client with support and helps to prevent the client from becoming overwhelmed or getting injured. Allowing the client to pace alone until physically tired.
choice A can increase the sense of isolation and anxiety. Asking a small group of other clients to walk with the client.
choice C may be inappropriate or even harmful in some cases. Calmly instructing the client to stop pacing and sit in the dayroom.
choice D can be perceived by the client as dismissive and may escalate the anxiety level. The nurse should work with the client and their family to develop an individualized plan of care that meets the client's needs and goals.
