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. The nurse is teaching a client about coronary artery disease (CAD) preventive health. Which behavior stated by the client indicates a need for additional information and teaching?
- A. Increasing physical activity.
- B. Eating a low-fat diet.
- C. Decreasing the number of cigarettes smoked per day.
- D. Monitoring blood pressure regularly.
Correct answer: C
Rationale: The correct answer is C. Decreasing the number of cigarettes smoked per day is not sufficient for CAD prevention. Smoking cessation is crucial in reducing the risk of CAD. While increasing physical activity, eating a low-fat diet, and monitoring blood pressure regularly are all positive behaviors for CAD prevention, quitting smoking should be emphasized due to its significant impact on cardiovascular health.
3. Parents of a 6-month-old child, who has just been diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What would be the best response by the nurse?
- A. Are you sure your child has iron deficiency anemia?
- B. This happens when the maternal stores of iron are depleted at about 6 months.
- C. This anemia is caused by blood loss.
- D. The child may not have had it for a long time.
Correct answer: B
Rationale: The best response by the nurse would be choice B: 'This happens when the maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent at about 6 months of age in a full-term infant when the maternal stores of iron are depleted. Choice A is incorrect because it questions the diagnosis provided by the healthcare provider. Choice C is incorrect because iron deficiency anemia in infants is primarily due to insufficient iron intake rather than blood loss. Choice D is incorrect as iron deficiency anemia typically develops gradually due to inadequate iron intake.
4. After hospitalization for SIADH, a client develops pontine myelinolysis. Which intervention should the nurse implement first?
- A. Reorient the client to the room
- B. Place an eye patch on one eye
- C. Evaluate the client's ability to swallow
- D. Perform range of motion exercises
Correct answer: C
Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.
5. The nurse reports that a client is at risk for a brain attack (stroke) based on which assessment finding?
- A. Nuchal rigidity
- B. Carotid bruit
- C. Jugular vein distention
- D. Palpable cervical lymph node
Correct answer: B
Rationale: The correct answer is B: Carotid bruit. A carotid bruit is a significant risk factor for stroke as it indicates turbulent blood flow due to narrowing of the carotid artery. Nuchal rigidity is associated with meningitis, jugular vein distention can be a sign of heart failure, and palpable cervical lymph nodes may indicate infection, but they are not directly linked to stroke risk.
