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 6-month-old infant who is being treated for developmental dysplasia of the hip has been placed in a hip spica cast. The nurse should teach the parents to
- A. Gently rub the skin with a cotton swab to relieve itching
- B. Place the favorite books and push-pull toys in the crib
- C. Check every few hours for the next day or 2 for swelling in the baby's feet
- D. Turn the baby with the abduction stabilizer bar every 2 hours
Correct answer: C
Rationale: The correct answer is to check every few hours for the next day or 2 for swelling in the baby's feet. Swelling in the baby's feet could indicate compromised circulation due to the cast, and frequent checks are necessary to ensure that there are no complications. Choices A, B, and D are incorrect because rubbing the skin with a cotton swab, placing favorite items in the crib, and turning the baby with the abduction stabilizer bar do not address the potential issue of compromised circulation and swelling in the baby's feet.
3. 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?
- A. Intraventricular hemorrhage
- B. Retinopathy of prematurity
- C. Bronchopulmonary dysplasia
- D. Necrotizing enterocolitis
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.
4. While assessing an Rh-positive newborn whose mother is Rh-negative, the nurse recognizes the risk for hyperbilirubinemia. Which of the following should be reported immediately?
- A. Jaundice evident at 26 hours
- B. Hematocrit of 55%
- C. Serum bilirubin of 12 mg/dL
- D. Positive Coombs test
Correct answer: C
Rationale: A serum bilirubin level of 12 mg/dL in a newborn is concerning and can indicate a significant risk of hyperbilirubinemia, which requires immediate medical intervention to prevent complications like kernicterus. Jaundice at 26 hours (Choice A) is a symptom, not a laboratory result, and needs monitoring but not an immediate report. Hematocrit of 55% (Choice B) may be elevated but is not indicative of hyperbilirubinemia. A positive Coombs test (Choice D) indicates the presence of antibodies on the newborn's red blood cells but does not directly correlate with the risk of hyperbilirubinemia.
5. A female client diagnosed with genital herpes simplex virus 2 (HSV 2) complains of dysuria, dyspareunia, leukorrhea, and lesions on the labia and perianal skin. A primary nursing action with the focus of comfort should be to
- A. Suggest 3 to 4 warm sitz baths per day
- B. Cleanse the genitalia twice a day with soap and water
- C. Spray warm water over genitalia after urination
- D. Apply heat or cold to lesions as desired
Correct answer: A
Rationale: The correct answer is to suggest 3 to 4 warm sitz baths per day. Warm sitz baths can soothe the irritated genital area, reduce pain, and promote healing of the lesions associated with genital herpes. Cleansing the genitalia with soap and water or spraying warm water over the genitalia after urination may further irritate the lesions. Applying heat or cold to lesions as desired may not provide the same level of comfort and healing as warm sitz baths.
