HESI Practice Test Pediatrics
1. A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)
- A. 4.2 mL
- B. 5 mL
- C. 3.6 mL
- D. 4 mL
Correct answer: A
Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.
2. An adolescent female who is leaning forward with her hands on her knees to breathe tells the practical nurse that she has been using triamcinolone (Azmacort) inhalation aerosol before coming to the clinic. Which action should the PN implement?
- A. Obtain vital signs and assess breath sounds for wheezing.
- B. Collect a blood sample for white blood cell count.
- C. Give the client a nebulizer breathing treatment.
- D. Administer another dose of Azmacort.
Correct answer: A
Rationale: When a patient presents with breathing difficulties, the first action should be to assess vital signs and breath sounds to evaluate the severity of the condition. This assessment will provide crucial information to determine the appropriate course of action and treatment. Collecting a blood sample for a white blood cell count, giving a nebulizer treatment, or administering another dose of Azmacort would not be the initial priority in this situation. Therefore, option A is the correct choice as it focuses on assessing the patient's respiratory status to guide further interventions.
3. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?
- A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
- B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
- C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
- D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles
Correct answer: A
Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.
4. A 2-year-old is admitted to the hospital with possible encephalitis, and a lumbar puncture is scheduled. Which information should the nurse provide this child concerning the procedure?
- A. Describe the side-lying, knees-to-chest position that must be assumed during the procedure.
- B. Explain that fluids cannot be taken for 8 hours before the procedure and for 4 hours after the procedure.
- C. Reassure the child that there will be no restrictions on activity after the procedure is completed.
- D. Tell the child to expect loud clicking noises during the procedure that may be slightly annoying.
Correct answer: A
Rationale: Children, especially young ones, benefit from knowing what position they will be in during a procedure as it helps them understand and feel more in control. Describing the side-lying, knees-to-chest position can reduce anxiety and promote cooperation during the lumbar puncture. Choice B is incorrect because the question is about preparing the child for the procedure, not about pre-procedure fasting requirements. Choice C is incorrect because there may be restrictions on activity after the procedure. Choice D is incorrect because mentioning loud clicking noises may increase the child's anxiety and fear.
5. What information should be reinforced with the parents about introducing solid foods to their infant?
- A. Begin with one tablespoon of the food.
- B. Introduce each food 4 to 7 days apart.
- C. Mix the new food with rice cereal.
- D. Remove foods when the infant refuses them.
Correct answer: B
Rationale: The correct answer is B. Introducing solid foods 4 to 7 days apart is crucial as it allows time to identify any allergic reactions or intolerances to specific foods. This gradual introduction helps parents monitor their infant's response to new foods and pinpoint any potential issues, ensuring the infant's safety and well-being. Choices A, C, and D are incorrect because starting with one tablespoon of the food, mixing new food with rice cereal, and removing foods when the infant refuses them are not recommended practices for introducing solid foods to infants.
