Nursing Elites

1. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

2. Following a cardiac catheterization and placement of a stent in the right coronary artery, the nurse administers prasugrel, a platelet inhibitor, to the client. To monitor for adverse effects from the medication, which assessment is most important for the nurse to include in this client's care plan?

• A. Check platelet count
• B. Observe the color of urine
• C. Review liver function tests
• D. Monitor for bleeding

Correct answer: D

Rationale: Prasugrel is a platelet inhibitor, which increases the risk of bleeding. Monitoring for bleeding, particularly at the catheterization site and in other areas, is the most important assessment following administration of the drug. Checking platelet count and observing urine color are relevant but not as immediate. Reviewing liver function tests is not directly related to the adverse effects of prasugrel.

3. Which of these findings would the nurse more closely associate with anemia in a 10-month-old infant?

• A. Hemoglobin level of 12 g/dL
• B. Pale mucosa of the eyelids and lips
• C. Hypoactivity
• D. A heart rate between 140 to 160

Correct answer: B

Rationale: The correct answer is B. Pale mucous membranes, such as those of the eyelids and lips, are a classic sign of anemia in infants. Anemia leads to decreased oxygen-carrying capacity, resulting in tissue hypoxia, which can manifest as pale mucosa. Choice A, a hemoglobin level of 12 g/dL, is within the normal range for a 10-month-old infant and would not necessarily indicate anemia. Choice C, hypoactivity, is a non-specific finding and can be present in various conditions, not specifically anemia. Choice D, a heart rate between 140 to 160, is within the normal range for an infant and is not a specific finding associated with anemia.

4. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to lead poisoning?

• A. An 8-year-old who lives in a housing project.
• B. A 2-year-old who plays on aging playground equipment.
• C. An adolescent who works in a paint factory.
• D. A 10-year-old with Type 1 diabetes.

Correct answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are at higher risk of lead poisoning due to their hand-to-mouth behavior and exploration of their environment. Aging playground equipment may have lead-based paint that can be ingested by the child. While children living in housing projects are also at risk due to lead-based paint in older buildings, the 2-year-old child playing on potentially lead-contaminated playground equipment is the most susceptible in this scenario. The adolescent working in a paint factory may face occupational hazards related to lead exposure, but the immediate risk from environmental sources is higher for the 2-year-old. Type 1 diabetes in a 10-year-old is not directly linked to an increased susceptibility to lead poisoning.

5. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?

• A. Check the client's oxygen saturation.
• B. Assess the client's endotracheal tube for obstruction.
• C. Reposition the client to relieve pressure.
• D. Suction the client's airway.

Correct answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.
