ATI Pediatrics Proctored Test
1. You are dispatched to a residence for a 5-year-old child who is not breathing. Upon arrival, you find the child supine on the floor, cyanotic, and unresponsive. You should first:
- A. begin chest compressions.
- B. open the airway and give two rescue breaths.
- C. apply an AED and analyze the rhythm.
- D. ask the parent for the child's medical history.
Correct answer: B
Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.
2. A client with diabetes has a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that should be prepared in the insulin syringe?
- A. 42 units
- B. 14 units
- C. 28 units
- D. 32 units
Correct answer: A
Rationale: To calculate the total number of units of insulin, you need to add the 14 units of regular insulin to the 28 units of NPH insulin, which equals 42 units. Therefore, the nurse should prepare 42 units of insulin in the syringe for the client.
3. A nurse is preparing a discharge teaching plan for a client who is to begin long-term oral prednisone for asthma. Which of the following instructions should the nurse include in the plan?
- A. Stop taking the medication if a rash occurs.
- B. Take the medication on an empty stomach to enhance absorption.
- C. Schedule the medication on alternate days to decrease adverse effects.
- D. Treat shortness of breath with an extra dose of the medication.
Correct answer: C
Rationale: When initiating long-term oral prednisone therapy for asthma, it is essential to schedule the medication on alternate days. This approach helps reduce the risk of adverse effects commonly associated with corticosteroid use. Choice A is incorrect because abrupt discontinuation of prednisone can lead to adrenal insufficiency. Choice B is incorrect as prednisone should be taken with food to minimize gastrointestinal side effects. Choice D is incorrect because using an extra dose of prednisone to treat shortness of breath is not appropriate and can lead to overdosing.
4. A nurse is assessing a client who has diabetes insipidus and is receiving desmopressin. Which of the following should the nurse monitor?
- A. Fasting blood glucose
- B. Carbohydrate intake
- C. Hematocrit
- D. Weight
Correct answer: D
Rationale: The correct answer is D: Weight. Desmopressin can cause fluid retention, so monitoring the client's weight is crucial to detect signs of water intoxication or overhydration, which can occur with the medication. Monitoring fasting blood glucose (choice A) is not directly related to desmopressin use in diabetes insipidus. Carbohydrate intake (choice B) is important for diabetes management but is not specifically relevant to monitoring desmopressin therapy. Hematocrit (choice C) is not typically influenced by desmopressin use in diabetes insipidus.
5. How is the enzyme trypsin activated?
- A. By zymogen.
- B. By bile.
- C. By gastrin.
- D. By enterokinase.
Correct answer: D
Rationale: The correct answer is D: By enterokinase. Trypsin is activated by enterokinase, an enzyme secreted by the small intestine. Enterokinase plays a crucial role in converting trypsinogen into its active form, trypsin. Choices A, B, and C are incorrect because trypsin is specifically activated by enterokinase, not by zymogen, bile, or gastrin.
