A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?
- A. 16 ml/hour.
- B. 18 ml/hour.
- C. 20 ml/hour.
- D. 22 ml/hour.
Correct Answer: C
Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.

When selecting patient problems for the 4-year-old child with nephrosis, what should be a priority for the nurse?
- A. Impaired body image
- B. Skin impairment
- C. Nutritional deficit
- D. Injury
Correct Answer: B
Rationale: The correct answer is B: Skin impairment. Nephrosis is characterized by gross edema, making skin care a priority. Skin impairment can result from the edema and needs close monitoring and management. While nutritional deficit and injury are important considerations in patient care, they are not the priority when dealing with a child with nephrosis. Impaired body image is not typically a priority in the immediate care of a young child with nephrosis.
How is gastroesophageal reflux (GER) typically treated in infants?
- A. By placing the infant NPO
- B. By thickening the formula or breast milk with cereal
- C. By placing the infant to sleep on the side
- D. By switching the infant to cow's milk
Correct Answer: B
Rationale: Gastroesophageal reflux (GER) in infants is typically treated by thickening the formula or breast milk with cereal. This helps reduce reflux episodes by making the feedings heavier and less likely to come back up. Placing the infant NPO (nothing by mouth) is not the typical treatment for GER as infants need proper nutrition for growth. Placing the infant to sleep on the side is not recommended due to the risk of SIDS; infants should be placed on their back to sleep. Switching the infant to cow's milk is also not a treatment for GER, as cow's milk can be harder to digest and may exacerbate symptoms.
How should the nurse record the observation of a child with Duchenne muscular dystrophy rising from the floor by walking up the thighs with the hands?
- A. Hand assistance
- B. Leg crawling
- C. Gowers sign
- D. Bright sign
Correct Answer: C
Rationale: The correct term for a child with Duchenne muscular dystrophy rising from the floor by walking up the thighs with the hands is known as the Gowers sign. This maneuver is characteristic of Duchenne muscular dystrophy due to proximal muscle weakness. Choices A, B, and D are incorrect because they do not specifically describe the action of walking up the thighs with the hands, which is a distinctive feature of the Gowers sign.
An adult client is admitted with AIDS and oral candidiasis manifested by several painful mouth ulcers. The nurse delegates oral care to the unlicensed assistive personnel (UAP) and discusses how to assist the client. Which instruction should the nurse provide the UAP?
- A. Assist with personal care, but leave oral care for the nurse to complete.
- B. Provide a soft bristle brush for the client to use during oral care.
- C. Use alcohol-based mouthwash to clean the ulcers.
- D. Apply an antifungal cream to the mouth ulcers.
Correct Answer: B
Rationale: The correct answer is B: 'Provide a soft bristle brush for the client to use during oral care.' Providing a soft bristle brush helps reduce trauma to the oral mucosa and assists in oral care. Choice A is incorrect because oral care can be safely delegated to UAPs. Choice C is wrong as alcohol-based mouthwash can further irritate the ulcers. Choice D is incorrect as applying an antifungal cream directly to the mouth ulcers is not the standard treatment for oral candidiasis.
After a CT scan with intravenous contrast medium, a client returns to the room complaining of shortness of breath and itching. Which intervention should the nurse implement?
- A. Call respiratory therapy to administer a breathing treatment.
- B. Send for an emergency tracheostomy set.
- C. Prepare a dose of epinephrine.
- D. Review the client's complete list of allergies.
Correct Answer: C
Rationale: Preparing a dose of epinephrine is the correct intervention in this situation as the client is displaying symptoms of an anaphylactic reaction to the contrast medium used during the CT scan. Epinephrine is the first-line treatment for anaphylaxis due to its ability to reverse the symptoms rapidly. Calling respiratory therapy for a breathing treatment (Choice A) may not address the underlying allergic reaction and delay appropriate treatment. Sending for an emergency tracheostomy set (Choice B) is not indicated as the client's symptoms suggest an allergic reaction rather than airway obstruction. Reviewing the client's complete list of allergies (Choice D) is important but would not provide immediate relief for the client's current symptoms; administering epinephrine takes precedence in this situation.
