Community Health HESI Practice Exam Questions
Question 1 of 4
The client with Raynaud's phenomenon would benefit most by which teaching intervention?
Correct Answer: A
Rationale: The correct answer is A: Stop smoking. Smoking causes vasoconstriction, worsening the symptoms of Raynaud's phenomenon. Quitting smoking is crucial in managing this condition effectively. Choices B, C, and D are not as directly related to the pathophysiology of Raynaud's phenomenon. While keeping feet dry and reducing stress can be beneficial for overall health, they are not as directly linked to managing Raynaud's phenomenon as smoking cessation.
Question 2 of 4
When the nurse identifies what appears to be ventricular tachycardia on the cardiac monitor of a client being evaluated for possible myocardial infarction, the first action the nurse should perform is to
Correct Answer: D
Rationale: The correct first action for the nurse to take when identifying what appears to be ventricular tachycardia in a client being evaluated for possible myocardial infarction is to assess the client's airway, breathing, and circulation. This step is crucial to determine the client's stability and the need for immediate intervention. Beginning cardiopulmonary resuscitation or preparing for immediate defibrillation without first assessing the airway, breathing, and circulation could delay potentially life-saving interventions. Notifying the 'Code' team and healthcare provider should come after ensuring the client's immediate needs are addressed.
Question 3 of 4
A client is scheduled to have a blood test for cholesterol and triglycerides the next day. The nurse would tell the client
Correct Answer: B
Rationale: Fasting for at least 12 hours is necessary before a cholesterol and triglyceride test to ensure accurate results by avoiding fluctuations that can occur after eating. Choice A is incorrect because a fat-free diet is not required; fasting is. Choice C is incorrect as it suggests having the test right after eating, which can affect the results. Choice D is incorrect as there is no need to stay at the laboratory for 2 blood samples unless specifically instructed by a healthcare provider.
Question 4 of 4
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?
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.
