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. In reviewing the assessment data of a client suspected of having diabetes insipidus, the nurse expects which of the following after a water deprivation test?
- A. Increased edema and weight gain
- B. Unchanged urine specific gravity
- C. Rapid protein excretion
- D. Decreased blood potassium
Correct answer: B
Rationale: After a water deprivation test in a client suspected of having diabetes insipidus, the nurse would expect the urine specific gravity to remain unchanged. This occurs because in diabetes insipidus, the kidneys are unable to concentrate urine, leading to a low urine specific gravity even after water deprivation. Choices A, C, and D are incorrect. Increased edema and weight gain are not typical findings in diabetes insipidus. Rapid protein excretion is not directly related to the condition, and decreased blood potassium is not a common outcome of a water deprivation test for diabetes insipidus.
3. The increasing number of people who must learn to live with chronic illness in the community implies the need for the PHN to plan and implement a program on:
- A. communicable disease control
- B. health education
- C. child survival
- D. environmental education
Correct answer: B
Rationale: The correct answer is B: health education. Health education is crucial for individuals dealing with chronic illnesses as it helps them learn how to manage their conditions effectively. Communicable disease control (choice A) focuses on preventing the spread of infectious diseases, which is not directly related to managing chronic conditions. Child survival (choice C) pertains to initiatives aimed at reducing child mortality rates, which is not directly related to addressing chronic illnesses. Environmental education (choice D) involves raising awareness about environmental issues, which is also not directly related to helping individuals live with chronic illnesses.
4. A newborn presents with a pronounced cephalic hematoma following a birth in the posterior position. Which nursing diagnosis should guide the plan of care?
- A. Pain related to periosteal injury
- B. Impaired mobility related to bleeding
- C. Parental anxiety related to knowledge deficit
- D. Injury related to intracranial hemorrhage
Correct answer: C
Rationale: The correct nursing diagnosis to guide the plan of care for a newborn with a pronounced cephalic hematoma following a birth in the posterior position is 'Parental anxiety related to knowledge deficit.' This is appropriate because the parents may be worried about the appearance and potential complications of the cephalic hematoma. They may require education and reassurance from the nurse. Choices A, B, and D are incorrect because they do not address the emotional needs of the parents and the knowledge deficit they may have regarding the condition.
5. A client with a peptic ulcer is scheduled for a vagotomy and pyloroplasty. The nurse explains that the purpose of this surgery is to:
- A. Increase acid secretion
- B. Reduce acid secretion
- C. Promote gastric emptying
- D. Remove the ulcerated area
Correct answer: B
Rationale: The correct answer is B: "Reduce acid secretion." Vagotomy is performed to reduce acid secretion by cutting the vagus nerve, which stimulates acid production. Choices A, C, and D are incorrect. A vagotomy does not increase acid secretion, promote gastric emptying, or remove the ulcerated area. It specifically aims to decrease acid production to help in the healing of peptic ulcers.
