1. A healthcare provider is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?
- A. 125 mL/hr
- B. 100 mL/hr
- C. 150 mL/hr
- D. 200 mL/hr
Correct answer: A
Rationale: To calculate the flow rate, divide the total volume by the total time: (750 mL / 6 hr) = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.
2. A client has a new prescription for combination oral NRTIs for the treatment of HIV. Which of the following statements should the nurse include in discharge teaching?
- A. These medications work by inhibiting enzymes to prevent HIV replication.
- B. These medications work by preventing protein synthesis within the HIV cell.
- C. These medications work by weakening the cell wall of the HIV virus.
- D. These medications work by blocking HIV entry into cells.
Correct answer: A
Rationale: The correct answer is A. NRTI antiretroviral medications inhibit the enzyme reverse transcriptase, which is essential for HIV replication. By blocking this enzyme, the medications prevent the virus from replicating and spreading. This mechanism of action helps to control the progression of HIV infection in the body. Choices B, C, and D are incorrect because NRTIs do not work by preventing protein synthesis, weakening the cell wall of the virus, or blocking HIV entry into cells. These mechanisms are associated with different classes of antiretroviral medications used in HIV treatment.
3. A healthcare professional is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?
- A. Ensure that the client has a patent IV line before obtaining the blood product from the refrigerator.
- B. Obtain help from another healthcare professional to confirm the correct client and blood product.
- C. Take a complete set of vital signs before beginning the transfusion and periodically during the transfusion.
- D. Stay with the client for the first 15 to 30 minutes of the transfusion.
Correct answer: B
Rationale: Obtaining help from another healthcare professional to confirm the correct client and blood product is crucial in preventing an acute hemolytic reaction during a blood transfusion. This reaction occurs due to ABO or Rh incompatibility. Verifying the correct client and blood product reduces the risk of administering the wrong blood type, which could lead to a life-threatening reaction. Checking for patency of the IV line (Choice A) is important but does not directly prevent an acute hemolytic reaction. Monitoring vital signs (Choice C) is essential for detecting transfusion reactions but does not prevent them. Staying with the client (Choice D) is important for early recognition of adverse reactions but does not address the root cause of preventing an acute hemolytic reaction.
4. A client has a new prescription for Phenelzine for the treatment of depression. Which of the following indicates that the client has developed an adverse effect of this medication?
- A. Orthostatic hypotension
- B. Hearing loss
- C. Gastrointestinal bleeding
- D. Weight loss
Correct answer: A
Rationale: Orthostatic hypotension is a known adverse effect of MAOIs, such as Phenelzine. It is characterized by a drop in blood pressure upon standing, which can lead to dizziness or fainting. Monitoring for orthostatic hypotension is crucial when administering MAOIs to prevent potential complications. Hearing loss (Choice B) is not a typical adverse effect associated with Phenelzine. Gastrointestinal bleeding (Choice C) is more commonly linked to NSAIDs or anticoagulants. Weight loss (Choice D) is not a typical adverse effect of Phenelzine and is more likely related to other factors such as appetite changes or metabolic issues.
5. The client makes which statement about lifestyle changes to reduce the development and progression of coronary artery disease that indicates the need for further teaching?
- A. “I will check my weight regularly for any gain or loss.”
- B. “I’ll make sure to take my high blood pressure medications.”
- C. “I am attending a smoking cessation class.”
- D. “As long as I exercise, stress at my job will not bother me.”
Correct answer: D
Rationale: The client stating, 'As long as I exercise, stress at my job will not bother me,' indicates a misunderstanding of the relationship between exercise and stress management. It is important to clarify that while exercise can help reduce stress, it may not eliminate all stressors, especially those related to work. Further teaching is needed to ensure the client understands the multifactorial approach required to address stress and its impact on coronary artery disease.
