Rotation sites for insulin injection should be separated from one another by 2.5 cm (1 inch) and should be used only every:

Correct Answer: D

Rationale: The correct answer is D (2-4 weeks) because rotating injection sites every 2-4 weeks helps prevent lipodystrophy and tissue damage. Insulin absorption may vary with frequent rotation, affecting glucose control. Choice A is too frequent and may lead to overuse of specific sites, increasing the risk of complications. Choice B is also too frequent and doesn't allow enough time for the tissue to recover. Choice C is too long, increasing the likelihood of uneven insulin absorption and potential complications. Rotation every 2-4 weeks strikes a balance between preventing damage and ensuring consistent insulin absorption.

Correct Answer: A

Rationale: Norepinephrine is a vasoconstrictor that increases blood pressure. In hypovolemic shock, there is insufficient blood volume, so vasoconstriction can worsen tissue perfusion. Neurogenic shock is characterized by vasodilation, so norepinephrine can help increase blood pressure. Choice C is incomplete and irrelevant. Norepinephrine is not used to treat diabetes.

Correct Answer: D

Rationale: The correct answer is D because chemotherapy dosing is usually based on the total body weight of the patient. Weighing and measuring the height of the patient on the day of administration helps ensure accurate dosing calculations. A: Before administering chemotherapy the nurse should - This is a general statement and does not specifically address the need for accurate dosing based on body weight. B: Get the body mass index (BMI) - BMI alone may not provide accurate dosing information as it does not directly measure total body weight. C: Ask the client about intake and output - Intake and output monitoring is important for assessing fluid balance but does not directly relate to chemotherapy dosing based on body weight.

Correct Answer: A

Rationale: The correct answer is A because the Principle of Atraumatic Care emphasizes minimizing pain and discomfort during medical procedures. This includes reducing any pain associated with drug administration. Choice B is incorrect as it refers to building a relationship with the family, not specifically related to pain reduction. Choice C is incorrect as restraining infants goes against the principle of atraumatic care. Choice D is incorrect as keeping the child apart from family members can increase anxiety and distress, contradicting the principle of atraumatic care. So, the correct answer is A because it aligns with the core principle of minimizing pain and trauma during care.
