Community Health HESI Practice Exam
1. What is the measure of the number of new cases of a disease in a specific population during a certain time period called?
- A. Prevalence
- B. Incidence
- C. Mortality rate
- D. Morbidity rate
Correct answer: B
Rationale: The correct answer is B, Incidence. Incidence refers to the number of new cases of a disease in a specific population during a certain time period. Prevalence (choice A) refers to the total number of cases of a disease in a population at a specific point in time. Mortality rate (choice C) is the measure of the number of deaths in a particular population due to a specific cause. Morbidity rate (choice D) is a broader term that encompasses the incidence and prevalence of a disease in a population.
2. During the beginning shift assessment of a client with asthma who is receiving oxygen via nasal cannula at 2 liters per minute, the nurse would be most concerned about which unreported finding?
- A. Pulse oximetry reading of 89%
- B. Crackles at the base of the lungs on auscultation
- C. Rapid shallow respirations with intermittent wheezes
- D. Excessive thirst with a dry cracked tongue
Correct answer: C
Rationale: Rapid, shallow respirations with intermittent wheezes are concerning as they indicate a potential worsening of the client's asthma. This finding suggests airway narrowing, which can lead to respiratory failure. Immediate intervention is required to address this respiratory distress. A pulse oximetry reading of 89% is low and indicates hypoxemia, but the respiratory pattern described in option C takes priority as it directly reflects the client's respiratory status. Crackles at the base of the lungs suggest fluid accumulation, which is important but not as immediately critical as the respiratory distress in asthma. Excessive thirst and a dry cracked tongue may indicate dehydration, which is relevant but not as urgent as the respiratory compromise presented in option C.
3. A client with schizophrenia is receiving haloperidol (Haldol). The nurse should monitor the client for which of the following side effects?
- A. Tachycardia
- B. Hypotension
- C. Extrapyramidal symptoms
- D. Hyperglycemia
Correct answer: C
Rationale: The correct answer is C: Extrapyramidal symptoms. Haloperidol is a first-generation antipsychotic that can lead to extrapyramidal symptoms such as tardive dyskinesia and akathisia. These side effects are common with the use of typical antipsychotics. Choice A, Tachycardia, is not a common side effect of haloperidol. Choice B, Hypotension, is also not a typical side effect associated with haloperidol use. Choice D, Hyperglycemia, is not directly linked to haloperidol administration, as it is more commonly associated with other medications like atypical antipsychotics or certain medical conditions.
4. A client has developed thrombophlebitis of the left leg. Which nursing intervention should be given the highest priority?
- A. Elevate leg on 2 pillows
- B. Apply support stockings
- C. Apply warm compresses
- D. Maintain complete bed rest
Correct answer: A
Rationale: The highest priority nursing intervention for a client with thrombophlebitis of the left leg is to elevate the leg on 2 pillows. Elevating the leg helps reduce swelling and pain associated with thrombophlebitis by promoting venous return. Applying support stockings (choice B) can be beneficial but is not the highest priority as elevation is more effective in the acute phase. Applying warm compresses (choice C) may worsen the condition by dilating the blood vessels, leading to increased pain and swelling. Maintaining complete bed rest (choice D) is important, but elevation takes precedence to improve circulation and reduce the risk of complications.
5. When a nurse from the surgical department is reassigned to the pediatric unit, the charge nurse should recognize that the child at highest risk for cardiac arrest and is the least likely to be assigned to this nurse is which child?
- A. Congenital cardiac defects
- B. An acute febrile illness
- C. Prolonged hypoxemia
- D. Severe multiple trauma
Correct answer: C
Rationale: The correct answer is C, 'Prolonged hypoxemia.' Prolonged hypoxemia is a critical condition that requires specialized pediatric care due to the high risk of cardiac arrest. The other choices, such as congenital cardiac defects, acute febrile illness, and severe multiple trauma, may also require attention, but prolonged hypoxemia poses the highest risk for cardiac arrest and demands specialized expertise in managing pediatric patients with this condition.
