A school nurse is assessing an adolescent who reports feeling shaky and is having difficulty speaking and concentrating on the Questions the nurse is asking. The nurse checks the adolescent’s blood glucose level and identifies a value of 55 mg/dL. Which of the following findings should the nurse expect?

A.

Polyuria.

B.

Dry, flushed skin.

C.

Deep, rapid respirations.

D.

Tachycardia.

Answer and Explanation

The Correct Answer is D

Choice A rationale

 

Polyuria, or excessive urination, is typically associated with hyperglycemia rather than hypoglycemia. In the context of diabetes, polyuria occurs when high blood glucose levels lead to increased urine production as the body attempts to excrete excess glucose. Since the adolescent’s blood glucose level is 55 mg/dL, which indicates hypoglycemia, polyuria is not an expected finding.

 

Choice B rationale

 

Dry, flushed skin is a common symptom of hyperglycemia, not hypoglycemia. When blood glucose levels are high, the body becomes dehydrated, leading to dry skin and a flushed appearance. In contrast, hypoglycemia often presents with symptoms such as sweating, pallor, and shakiness due to the body’s response to low blood glucose levels.

 

Choice C rationale

 

Deep, rapid respirations, also known as Kussmaul respirations, are typically associated with diabetic ketoacidosis (DKA), a complication of hyperglycemia. DKA occurs when the body produces high levels of ketones due to insufficient insulin. Since the adolescent’s blood glucose level is 55 mg/dL, which indicates hypoglycemia, deep, rapid respirations are not an expected finding.

 

Choice D rationale

 

Tachycardia, or an increased heart rate, is a common symptom of hypoglycemia. When blood glucose levels drop, the body releases catecholamines (such as adrenaline) to raise blood glucose levels. This response leads to symptoms such as shakiness, sweating, and tachycardia. Therefore, tachycardia is an expected finding in an adolescent with a blood glucose level of 55 mg/dL.

Correct Answer is B

Explanation

Choice A rationale

Insulin should be administered subcutaneously, not intramuscularly. Rotating sites is important to prevent lipodystrophy, but the correct technique involves subcutaneous injection.

Choice B rationale

Drawing up the short-acting insulin into the syringe first is correct. This prevents contamination of the short-acting insulin vial with long-acting insulin, ensuring accurate dosing.

Choice C rationale

Wiping off the needle with an alcohol swab is not recommended. The needle should remain sterile, and only the top of the insulin vial should be wiped with an alcohol swab.

Choice D rationale

Administering insulin at a 30-degree angle is incorrect. Insulin should be administered at a 90- degree angle if the person can grasp 2 inches of skin, or at a 45-degree angle if only 1 inch of skin can be grasped.

Correct Answer is A

Explanation

Choice A rationale

Measuring head circumference every shift is unnecessary for a 6-year-old child with bacterial meningitis. This intervention is more relevant for infants where head circumference changes can indicate increased intracranial pressure.

Choice B rationale

Implementing seizure precautions is necessary as bacterial meningitis can cause seizures due to increased intracranial pressure and inflammation.

Choice C rationale

Admitting the client to a private room is necessary to prevent the spread of infection, as bacterial meningitis can be highly contagious.

Choice D rationale

Placing the client in a semi-Fowler’s position helps reduce intracranial pressure and promotes comfort.
