Community Health HESI Practice Exam Questions
Question 1 of 5
The client with asthma who is sensitive to house dust-mites is being instructed by the nurse. Which information about prevention of asthma episodes would be the most helpful to include during the teaching?
Correct Answer: C
Rationale: The correct answer is to wash and rinse the bed linens in hot water to help eliminate dust mites, a common trigger for asthma episodes. Washing in hot water is more effective in killing dust mites compared to warm water. Changing pillow covers every month may help but is not as effective as washing bed linens in hot water. Using air filters in the furnace system may improve air quality but does not directly target dust mites on bed linens.
Question 2 of 5
The nurse is planning care for a client with increased intracranial pressure. The best position for this client is
Correct Answer: C
Rationale: The correct answer is C, Semi-Fowler's. This position helps to reduce intracranial pressure by promoting venous drainage from the head while maintaining adequate oxygenation. Option A, Trendelenburg position, is incorrect as it involves placing the patient with the head lower than the body, which can increase intracranial pressure. Option B, Prone position, is also incorrect as it involves lying on the stomach, which can further elevate intracranial pressure. Option D, Side-lying with head flat, does not provide the same benefits as the Semi-Fowler's position in terms of promoting venous drainage and maintaining oxygenation in a client with increased intracranial pressure.
Question 3 of 5
You are teaching a client about the patient-controlled analgesia (PCA) planned for post-operative care. Which statement indicates further teaching may be needed by the client?
Correct Answer: B
Rationale: PCA allows patients to self-administer pain medication within prescribed limits, without the need to call the nurse before taking an additional dose. Choice B suggests a misunderstanding of how PCA works, as the patient should be educated that they can self-administer doses within the safety parameters set by the healthcare provider. Choices A, C, and D demonstrate proper understanding of PCA, hence are not indicative of needing further teaching.
Question 4 of 5
A child and his family were exposed to Mycobacterium tuberculosis about 2 months ago. To confirm the presence or absence of an infection, it is most important for all family members to have a
Correct Answer: D
Rationale: The PPD (purified protein derivative) intradermal test is the standard screening method for detecting tuberculosis infection. It helps identify individuals who have been infected with Mycobacterium tuberculosis. A chest x-ray (Choice A) is used to assess the extent of active disease, not for screening purposes. Blood culture (Choice B) is not typically used for tuberculosis screening. Sputum culture (Choice C) is used to confirm active tuberculosis in symptomatic individuals, not for initial screening purposes.
Question 5 of 5
A 4-month-old child taking digoxin (Lanoxin) has a blood pressure of 92/78; resting pulse of 78; respirations 28, and a potassium level of 4.8 mEq/L. The client is irritable and has vomited twice since the morning dose of digoxin. Which finding is most indicative of digoxin toxicity?
Correct Answer: A
Rationale: Bradycardia (abnormally slow heart rate) is a key sign of digoxin toxicity. In this scenario, the child's symptoms of irritability, vomiting, along with the resting pulse of 78 despite being on digoxin, suggest an impending bradycardia due to digoxin toxicity. Lethargy can also be a sign, but in this case, the child is irritable rather than lethargic. Vomiting, though a symptom, is not as specific to digoxin toxicity as bradycardia. Irritability, while present, is not the most indicative finding of digoxin toxicity compared to bradycardia.
