HESI LPN
Community Health HESI Practice Exam
1. 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?
- A. Bradycardia
- B. Lethargy
- C. Irritability
- D. Vomiting
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.
2. A child is diagnosed with poison ivy. The mother tells the nurse that she does not know how her child contracted the rash since he had not been playing in wooded areas. As the nurse asks questions about possible contact, which of the following would the nurse recognize as highest risk for exposure?
- A. Playing with toys in a backyard flower garden
- B. Eating small amounts of grass while playing 'farm'
- C. Playing with cars on the pavement near burning leaves
- D. Throwing a ball to a neighborhood child who has poison ivy
Correct answer: C
Rationale: The correct answer is C. Poison ivy can be contracted through smoke from burning plants, which can carry the urushiol oil that causes the rash. Playing near burning leaves would be the highest risk for exposure in this scenario. Choices A, B, and D do not involve direct contact with burning plants or leaves, making them lower-risk activities for exposure to poison ivy.
3. The occurrence of non-communicable diseases (NCDs) is on the rise and is attributed to the changing lifestyle of Filipinos. The major NCDs are cardiovascular diseases (CVDs), cancer, chronic obstructive pulmonary disease (COPD), and diabetes mellitus (DM). The community health nurse can help address these problems. The major risk factors common to the above-mentioned four major NCDs are:
- A. Unhealthy diet, physical inactivity, and smoking
- B. Hypertension, sedentary lifestyle, and poor stress management
- C. Obesity, sedentary lifestyle, and smoking
- D. Unhealthy diet, alcoholism, and sedentary lifestyle
Correct answer: A
Rationale: The correct answer is A: 'Unhealthy diet, physical inactivity, and smoking.' These are major risk factors associated with cardiovascular diseases (CVDs), cancer, chronic obstructive pulmonary disease (COPD), and diabetes mellitus (DM). Unhealthy diet can lead to obesity and other health issues, physical inactivity contributes to various chronic conditions, and smoking is a well-known risk factor for cancer and respiratory diseases. Choice B is incorrect as hypertension is a condition that can result from these risk factors rather than being a risk factor itself. Poor stress management, although important for overall health, is not a major risk factor for the mentioned NCDs. Choice C is incorrect as although obesity is a risk factor, it is not mentioned in the question stem. Choice D is incorrect as alcoholism is not listed among the major NCDs or the common risk factors provided.
4. Mark, 9 months old, is given oral rehydration solution because of diarrhea with some dehydration. In your follow-up visit, you observed that Mark's eyes become puffy. Which one of the following would you advise Mark's mother?
- A. continue giving ORS but more slowly
- B. show mother how much solution to give
- C. stop ORS and give plain water or milk
- D. reassess patient to determine how much ORS to give
Correct answer: A
Rationale: In this scenario, observing puffy eyes in a child being treated with oral rehydration solution may indicate fluid overload. Continuing to give ORS but more slowly is the correct course of action as it helps manage hydration without overloading fluids. Choice B is not the best option in this situation as the issue is not about the quantity of the solution, but the rate of administration. Choice C is incorrect because plain water or milk is not a suitable alternative for rehydration in cases of dehydration. Choice D is also incorrect as reassessing the patient does not directly address the issue of puffy eyes, which suggests a need to adjust the administration of ORS.
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
- A. Chest x-ray
- B. Blood culture
- C. Sputum culture
- D. PPD intradermal test
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.
