Antivenins should be considered in the treatment of all of the following EXCEPT

Correct Answer: E

Rationale: Hymenoptera envenomations (e.g., bee stings) typically do not require antivenin, as they are managed with supportive care.

Correct Answer: A

Rationale: The observation that indicates adequate tissue perfusion to vital organs is a urinary output of 30 ml in an hour. Adequate tissue perfusion is essential to ensure that vital organs receive enough blood and oxygen. Monitoring urinary output is a crucial indicator of perfusion status, as it reflects the perfusion of the kidneys. A urinary output of at least 30 ml/hour or more indicates that the kidneys are receiving sufficient blood flow and are able to produce urine, which helps in removing waste products from the body. In this case, a urinary output of 30 ml in an hour suggests adequate tissue perfusion to vital organs. The other options do not directly reflect tissue perfusion to vital organs and may indicate inadequate perfusion or compromised hemodynamic status.

Correct Answer: B

Rationale: When planning education for the parents of a child with type 1 diabetes mellitus, the nurse should include rotating insulin injection sites. This is important to prevent lipohypertrophy, which is the buildup of fat under the skin, and to ensure consistent absorption of insulin. Rotating injection sites helps to maintain healthy tissue and promotes better insulin effectiveness in managing blood sugar levels. It is a key component of proper diabetes care and helps to reduce the risk of complications associated with continuous injection in the same area.
