Nursing Elites

1. 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.

2. 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.

3. The nurse is assessing a client who has herpes zoster. Which question will allow the nurse to gather further information about this condition?

• A. Has everyone at home already had varicella?
• B. Have the antifungal creams been effective?
• C. Do your family members share combs and brushes?
• D. Do you have any dry patches on your feet and hands?

Correct answer: A

Rationale: The correct answer is A: 'Has everyone at home already had varicella?' Herpes zoster (shingles) is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. By knowing if others at home had varicella (chickenpox), the nurse can assess the risk of transmission and provide appropriate guidance. Choice B is incorrect because antifungal creams are not effective for herpes zoster, which is a viral infection. Choice C is irrelevant to herpes zoster as it pertains to sharing personal items that may transmit head lice or certain skin infections. Choice D is also unrelated as it focuses on dry patches, not typical manifestations of herpes zoster which presents as a painful rash.

4. During a home visit, the nurse assesses the skin of a client with eczema who reports that an exacerbation of symptoms has occurred during the last week. Which information is most useful in determining the possible cause of the symptoms?

• A. An old friend with eczema came for a visit.
• B. Recently received an influenza immunization.
• C. A grandson and his new dog recently visited.
• D. Corticosteroid cream was applied to eczema.

Correct answer: C

Rationale: The correct answer is C. Contact with the grandson's new dog could have introduced new allergens or irritants, exacerbating the eczema symptoms. Choice A is unrelated to the exacerbation of symptoms. Choice B, receiving an influenza immunization, is unlikely to directly cause an exacerbation of eczema symptoms. Choice D, applying corticosteroid cream, is a common treatment for eczema and would not likely be the cause of the exacerbation.

5. The nurse uses a diagram to show that the tetralogy of Fallot involves a combination of four congenital defects. What are the defects?

• A. Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy
• B. Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
• C. Aortic stenosis, atrial septal defect, overriding aorta, right ventricular hypertrophy
• D. Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy

Correct answer: B

Rationale: The correct answer is B: Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. Tetralogy of Fallot involves these four congenital defects. Choice A is incorrect because it includes aortic stenosis instead of pulmonary stenosis, atrial septal defect instead of ventricular septal defect, and left ventricular hypertrophy instead of right ventricular hypertrophy. Choice C is incorrect as it includes aortic stenosis and atrial septal defect instead of pulmonary stenosis and ventricular septal defect. Choice D is incorrect because it includes aortic hypertrophy instead of overriding aorta.
