1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?
- A. 60 microdrops/minute
- B. 20 microdrops/minute
- C. 30 microdrops/minute
- D. 40 microdrops/minute
Correct answer: A
Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
2. A client is in her third month of her first pregnancy. During the interview, she tells the nurse that she has several sex partners and is unsure of the identity of the baby's father. Which of the following nursing interventions is a priority?
- A. Counsel the woman to consent to HIV screening.
- B. Perform tests for sexually transmitted diseases.
- C. Discuss her high risk for cervical cancer.
- D. Refer the client to a family planning clinic.
Correct answer: A
Rationale: In this scenario, the client's disclosure of having multiple sex partners and uncertainty about the baby's father indicates a potential high risk for HIV. Therefore, the priority nursing intervention is to counsel the woman to consent to HIV screening. Early detection of HIV is crucial for initiating timely treatment and improving outcomes. Choices B, C, and D are not the priority in this situation as HIV screening takes precedence over testing for other sexually transmitted diseases, discussing cervical cancer risk, or referring to a family planning clinic.
3. A patient underwent fiberoptic colonoscopy 18 hours ago and presents to the emergency department with increasing abdominal pain, fever, and chills. Which of the following conditions poses the most immediate concern?
- A. Bowel perforation
- B. Viral gastroenteritis
- C. Colon cancer
- D. Diverticulitis
Correct answer: A
Rationale: The correct answer is bowel perforation. Bowel perforation is the most serious complication of fiberoptic colonoscopy, with signs such as progressive abdominal pain, fever, chills, and tachycardia indicating advancing peritonitis. Although colonoscopic perforation is rare (0.03% to 0.7% incidence), it can lead to high mortality and morbidity rates. Viral gastroenteritis (Choice B) typically presents with symptoms like diarrhea, nausea, vomiting, and abdominal cramps, but it is not the most immediate concern in this scenario. Colon cancer (Choice C) and diverticulitis (Choice D) are important conditions but are less likely to present acutely after colonoscopy compared to bowel perforation.
4. A nurse is caring for a 2-day-old infant who has a bilirubin level of 19 mg/dl. The physician has ordered phototherapy. Which of the following actions indicates correct preparation of the infant for this procedure?
- A. Undress the baby down to a diaper and hat
- B. Place the baby in his mother's arms before turning on the light
- C. Position the phototherapy light approximately 3 inches above the baby's skin
- D. Secure eye protection for the infant without occluding the nose
Correct answer: D
Rationale: Phototherapy is used to treat high levels of bilirubin among infants, typically evidenced as jaundice. The nurse must position the infant carefully during this procedure to maximize the benefits of the light therapy while protecting the baby. Placing protective eyewear over the baby's eyes without covering the nose is crucial to shield the eyes from the ultraviolet light. Undressing the baby down to a diaper and hat (Choice A) is a standard practice to maximize skin exposure to the phototherapy light. Placing the baby in his mother's arms before turning on the light (Choice B) is not necessary for the preparation of the infant for phototherapy. Positioning the phototherapy light approximately 3 inches above the baby's skin (Choice C) is incorrect as the distance should be as recommended by the healthcare provider based on the manufacturer's instructions.
5. During an admission assessment on a 2-year-old child diagnosed with nephrotic syndrome, the nurse notes that which characteristic is most commonly associated with this syndrome?
- A. Hypertension
- B. Generalized edema
- C. Increased urinary output
- D. Frank, bright red blood in the urine
Correct answer: B
Rationale: Nephrotic syndrome in children is characterized by massive proteinuria, hypoalbuminemia, hyperlipidemia, and edema. The most common manifestation is generalized edema due to protein loss in the urine, leading to decreased plasma oncotic pressure. This results in fluid shifting into the interstitial spaces, causing edema. Hypertension is not a typical feature of nephrotic syndrome in children. Increased urinary output is not a common finding; instead, children with nephrotic syndrome often have decreased urine output due to decreased renal perfusion. The presence of frank, bright red blood in the urine is not a typical characteristic of nephrotic syndrome but may indicate a different renal condition such as glomerulonephritis.
