HESI LPN
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. Based on the Nursing diagnosis of 'Potential for infection related to second and third degree burns,' which intervention has the highest priority?
- A. Application of topical antibacterial cream
- B. Use of careful hand washing technique
- C. Administration of plasma expanders
- D. Limiting visitors to the burned client
Correct answer: B
Rationale: The highest priority intervention in this scenario is B, the use of careful hand washing technique. Proper hand hygiene is essential in preventing infection, especially in individuals with compromised skin integrity like those with burns. By practicing careful hand washing, healthcare providers reduce the risk of introducing harmful pathogens to the burn wound, thus lowering the chances of infections. Choice A, application of topical antibacterial cream, is important but should follow ensuring proper hand hygiene. Choice C, administration of plasma expanders, is not directly associated with preventing burn-related infections. Choice D, limiting visitors, is significant for infection control, but ensuring proper hand hygiene outweighs this intervention in terms of priority.
3. A group of students is reviewing information about the various types of insulin used to treat type 1 diabetes. The students demonstrate understanding of the information when they identify which of these insulins as having the longest duration?
- A. Lispro
- B. Regular
- C. NPH
- D. Glargine
Correct answer: D
Rationale: The correct answer is Glargine (Lantus) as it has the longest duration of action among the insulins listed, lasting 12 to 24 hours. Lispro (A) and Regular (B) are rapid-acting insulins with shorter durations of action. NPH (C) is an intermediate-acting insulin with a duration of action of about 12-16 hours. Therefore, Glargine is the correct choice for the insulin with the longest duration.
4. A nurse observes a family member administer a rectal suppository by having the client lie on the left side for the administration. The family member pushed the suppository until the finger went up to the second knuckle. After 10 minutes the client was told by the family member to turn to the right side and the client did this. What is the appropriate comment for the nurse to make?
- A. Why don’t we now have the client turn back to the left side.
- B. That was done correctly. Did you have any problems with the insertion?
- C. Let’s check to see if the suppository is in far enough.
- D. Did you feel any stool in the intestinal tract?
Correct answer: B
Rationale: The appropriate comment by the nurse is to affirm the correct technique while offering support and checking for any issues during the insertion.
5. A client is experiencing a severe sore throat, pain when swallowing, and swollen lymph nodes. Which of the following stages of infection is the client likely in?
- A. Prodromal
- B. Incubation
- C. Convalescence
- D. Illness
Correct answer: D
Rationale: The client in this scenario is in the illness stage of infection. During this stage, the individual exhibits specific symptoms such as a severe sore throat, pain when swallowing, and swollen lymph nodes. The prodromal stage precedes the appearance of specific symptoms and is characterized by nonspecific signs. The incubation period occurs between exposure to the pathogen and the onset of symptoms. Convalescence is the recovery period following the resolution of the infection. Therefore, the correct answer is 'D: Illness' as it aligns with the symptoms presented by the client.
