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 C
Explanation
The parents report that the child injured herself by falling off the couch.
A spiral fracture is a type of broken bone that occurs when a twisting force is applied to the bone. It is often seen in cases of child abuse, where the abuser grabs and twists the child's arm or leg.
Choice A is not correct because bringing the child to the facility soon after the injury does not rule out abuse. The abuser may have done so to avoid suspicion or to prevent further complications.
Choice B is not correct because crying when the arm is examined is a normal reaction for a child who is in pain and scared. It does not indicate abuse or neglect.
Choice C is correct because it is unlikely that a fall from a couch would cause a spiral fracture of the ulna and radius. These bones are strong and require a lot of force to break. A fall from a couch would more likely cause a greenstick fracture, which is a partial break of the bone that occurs in children with flexible bones.
Choice D is not correct because a single injury does not exclude abuse. The child may have been abused before and healed without medical attention, or the abuser may have targeted only one part of the body. A single injury should still raise suspicion and prompt further investigation.
Correct Answer is D
Explanation
When collecting data from a female client who has anorexia nervosa, the nurse should expect a finding of low bone density.
Anorexia nervosa is an eating disorder characterized by self-starvation, distorted body image, and a fear of gaining weight. Clients with anorexia nervosa are at risk for severe malnutrition, which can lead to a variety of complications, including bone loss and osteoporosis.
Options A, B, and C are incorrect findings in a client with anorexia nervosa. Decreased cholesterol levels may be an indication of malnutrition. Heavy monthly periods, or menstrual irregularities, may occur in clients with anorexia nervosa because of the hormonal changes that can result from severe weight loss. Elevated serum potassium levels are not a common finding in a client with anorexia nervosa.
