Community Health HESI Practice Exam
1. When caring for premature newborns in an intensive care setting, a nurse carefully monitors oxygen concentration. What is the most common complication of this therapy?
- A. Intraventricular hemorrhage
- B. Retinopathy of prematurity
- C. Bronchopulmonary dysplasia
- D. Necrotizing enterocolitis
Correct answer: B
Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.
2. The public health RN is called to investigate a report of several cases of varicella at a daycare center. The daycare workers state that 5 children have been sent home over the past 2 weeks with fever and itchy blisters. Which intervention should the RN implement first?
- A. Validate that the children who were sent home had chickenpox.
- B. Ask the parents to take the child to see their pediatrician.
- C. Ask the parents to not send the child back to daycare until after 6 weeks.
- D. Tell the parents to send the child back to daycare; it was a mistake they were sent home.
Correct answer: A
Rationale: The correct answer is to validate that the children who were sent home had chickenpox. This is crucial in confirming the presence of varicella, which is necessary for appropriate management and control of the outbreak. Option B is not the first intervention because the focus initially is on verifying the cases within the daycare center. Option C is incorrect as it suggests a prolonged exclusion period without confirming the diagnosis. Option D is inappropriate and potentially harmful, as sending a child back without proper assessment can lead to further spread of the infection.
3. The nurse is teaching a group of older adults about medication safety. Which of the following should be included in the teaching?
- A. keeping a list of all medications and dosages
- B. sharing medications with family members if they have the same prescription
- C. stopping medications when symptoms improve
- D. doubling up on missed doses
Correct answer: A
Rationale: The correct answer is A: keeping a list of all medications and dosages. Maintaining a comprehensive list of medications and their dosages is essential for older adults to prevent medication errors and dangerous interactions. Choice B is incorrect because sharing medications, even if family members have the same prescription, can lead to unintended adverse effects or inappropriate dosages. Choice C is incorrect as stopping medications when symptoms improve can be harmful if the full course of treatment is not completed. Choice D is incorrect as doubling up on missed doses can result in overdosing and adverse reactions.
4. When discussing hypothyroidism and treatment with the family of a newborn, the nurse should emphasize
- A. Expecting mental retardation in the child is likely
- B. Administering thyroid hormone can prevent problems
- C. This rare problem is always hereditary
- D. Physical growth/development will be delayed
Correct answer: B
Rationale: The correct answer is B. Administering thyroid hormone to a newborn diagnosed with hypothyroidism can prevent developmental delays and mental retardation. This treatment is crucial to ensure optimal growth and development. Choice A is incorrect because with prompt treatment, mental retardation can be prevented. Choice C is incorrect as hypothyroidism can also be acquired and not only hereditary. Choice D is incorrect as physical growth and development can be supported through timely administration of thyroid hormone.
5. In 1996, there were 15 cases of Acute Respiratory Infection (ARI) in Barangay B, while Barangay C had 20 cases. The total number of children who have ARI is:
- A. higher in Barangay C than in Barangay B
- B. not comparable in Barangay B and C
- C. higher in Barangay B than in Barangay C
- D. data given is insufficient
Correct answer: A
Rationale: The correct answer is A: 'higher in Barangay C than in Barangay B.' This is because Barangay C had more cases of ARI (20) compared to Barangay B (15). Therefore, the total number of children who have ARI is higher in Barangay C. Choices B and C are incorrect because the data clearly shows that Barangay C had more cases than Barangay B. Choice D is also incorrect as there is sufficient data provided to compare the number of ARI cases between the two barangays.
