HESI Pediatrics Practice Exam
1. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?
- A. Laughs readily, turns from back to side.
- B. Has strong Moro and tonic neck reflexes.
- C. Keeps fists clenched, opens hands when grasping an object.
- D. Can lift head but not chest when lying on abdomen.
Correct answer: A
Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.
2. Which hormone is detected in pregnancy tests?
- A. Estrogen
- B. Progesterone
- C. Luteinizing hormone (LH)
- D. Human chorionic gonadotropin (hCG)
Correct answer: D
Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.
3. A nurse is reinforcing teaching about food choice with the mother of an 8-month-old infant. Which of the following statements by the mother indicates a need for further teaching?
- A. I will give my child peanut butter and mashed egg whites.
- B. I will give my child rice cereal and crackers.
- C. I will give my child pureed liver and strained pears.
- D. I will give my child applesauce and green peas.
Correct answer: A
Rationale: The correct answer is A because peanut butter and egg whites are not recommended for infants under 12 months due to the risk of choking and allergies. Choices B, C, and D are appropriate food choices for an 8-month-old infant. Rice cereal, crackers, pureed liver, strained pears, applesauce, and green peas are all suitable options for introducing solid foods to infants.
4. The client is being taught to choose foods rich in potassium to prevent digitalis toxicity. Which choice indicates the client understands dietary needs?
- A. Three apricots
- B. Medium banana
- C. Naval orange
- D. Baked potato
Correct answer: D
Rationale: The correct answer is D: Baked potato. Baked potatoes are rich in potassium, which is essential in preventing digitalis toxicity by helping to maintain normal electrolyte levels. Apricots, bananas, and oranges are also sources of potassium, but a baked potato has a higher potassium content compared to the other options, making it a more effective choice for preventing digitalis toxicity.
5. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning?
- A. Serum glucose of 500 mg/dl
- B. Blood pressure of 140/90 mmHg
- C. Serum osmolarity of 320 mOsm/kg
- D. Serum pH of 7.30
Correct answer: C
Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS). This level of osmolarity indicates severe dehydration and hyperosmolarity, putting the client at risk of complications like organ failure. Immediate intervention is crucial to address the dehydration and restore fluid balance. The other options, while important in the overall assessment of a client with HHS, do not directly indicate the severity of dehydration and hyperosmolarity seen with a high serum osmolarity level.
