1. A patient is prescribed acetaminophen 650 mg PO every 6 hr PRN for pain. The available acetaminophen liquid is 500 mg/5 mL. How many mL should the nurse administer per dose?

• A. 6.5 mL
• B. 7 mL
• C. 5 mL
• D. 8 mL

Correct answer: A

Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen. Choice B, 7 mL, is incorrect because the correct calculation results in 6.5 mL. Choice C, 5 mL, is incorrect as it is the concentration of the acetaminophen liquid, not the final volume needed. Choice D, 8 mL, is incorrect because it does not reflect the accurate calculation based on the prescription and concentration.

2. A client is taking lisinopril. Which of the following outcomes indicates a therapeutic effect of the medication?

• A. Decreased blood pressure
• B. Increase in HDL cholesterol
• C. Prevention of bipolar manic episodes
• D. Improved sexual function

Correct answer: A

Rationale: The therapeutic effect of lisinopril, an ACE inhibitor, is indicated by a decrease in blood pressure. Lisinopril works by relaxing blood vessels, leading to a reduction in blood pressure. Monitoring and achieving a decrease in blood pressure is a key outcome when managing hypertension with lisinopril. Choices B, C, and D are incorrect because lisinopril is not intended to increase HDL cholesterol, prevent bipolar manic episodes, or improve sexual function. Therefore, the correct outcome indicating the therapeutic effect of lisinopril is a decrease in blood pressure.

3. Which of the following is classified as a class IA Sodium Channel blocker?

• A. Quinidine
• B. Disopyramide
• C. Aminodarone
• D. Propafenone

Correct answer: A

Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.

4. A client is prescribed Bethanechol to treat urinary retention. Which of the following findings is a manifestation of muscarinic stimulation?

• A. Dry mouth
• B. Hypertension
• C. Excessive perspiration
• D. Fecal impaction

Correct answer: C

Rationale: Bethanechol is a muscarinic agonist, which stimulates muscarinic receptors. Activation of these receptors can lead to increased sweating (excessive perspiration) as a manifestation of muscarinic stimulation. Options A, B, and D are not typically associated with muscarinic stimulation. Dry mouth is a common side effect of anticholinergic medications, hypertension is not a common manifestation of muscarinic stimulation, and fecal impaction is not directly related to muscarinic receptor activation.

5. A healthcare provider 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 provider 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: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction. Choices A, C, and D are important aspects of transfusion safety but are not directly related to preventing acute hemolytic reactions. Ensuring a patent IV line, monitoring vital signs, and staying with the client are all essential during transfusion but do not specifically address the risk of ABO or Rh incompatibility reactions.
