1. A client is prescribed Propranolol for a dysrhythmia. Which of the following actions should the nurse plan to take?
- A. Hold Propranolol if the client's apical pulse is greater than 100/min.
- B. Administer Propranolol to decrease the client's blood pressure.
- C. Assist the client with sitting up or standing after taking this medication.
- D. Monitor the client for hypokalemia due to the risk of Propranolol toxicity.
Correct answer: C
Rationale: The correct action the nurse should plan to take when administering Propranolol is to assist the client when sitting up or standing after taking the medication. Propranolol can lead to orthostatic hypotension, causing dizziness upon sudden position changes. It is essential to help the client with position changes to prevent falls or injury. Holding Propranolol if the client's apical pulse is greater than 100/min (Choice A) is incorrect because Propranolol is often used to manage dysrhythmias and slowing down the heart rate. Administering Propranolol to decrease the client's blood pressure (Choice B) is not the primary indication for using this medication. Monitoring the client for hypokalemia due to the risk of Propranolol toxicity (Choice D) is not a direct effect of Propranolol; rather, it is more related to other medications like diuretics.
2. A healthcare professional 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 D5W 750 mL over 6 hours. Choice B (100 mL/hr) is incorrect because it does not accurately divide the total volume by the total time. Choice C (150 mL/hr) and Choice D (200 mL/hr) are incorrect as they are not the correct flow rates needed to infuse the D5W solution over the specified time period.
3. What information should you provide to your patient if they are taking sennosides? Select All That Apply.
- A. Sennosides should be used for short-term therapy
- B. The medication does not cure hypothyroidism
- C. The color of the urine may change to pink, red, violet, yellow, or brown
- D. Make sure to use other forms of bowel regulation
Correct answer: A
Rationale: When educating a patient taking sennosides, it is important to emphasize that these laxatives should be used for short-term therapy only. The medication does not address hypothyroidism, so this information is not relevant. Patients should be informed that the color of their urine may change to various colors like pink, red, violet, yellow, or brown, which is a common side effect of sennosides. It is advisable to incorporate other forms of bowel regulation alongside sennosides for optimal bowel health. Choice A is correct as it provides essential guidance on the duration of sennosides use. Choice B is incorrect because sennosides are not used to cure hypothyroidism. Choice C is correct as it highlights a common side effect of sennosides. Choice D is incorrect because it does not specifically relate to sennosides but rather suggests using other forms of bowel regulation in general.
4. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
5. When reviewing a client's health record, a healthcare professional notes that the client is experiencing episodes of hypokalemia. Which of the following medications should be identified as a cause of the client's hypokalemia?
- A. Captopril
- B. Lisinopril
- C. Furosemide
- D. Spironolactone
Correct answer: C
Rationale: Furosemide, a loop diuretic, can lead to hypokalemia by increasing the excretion of potassium in the urine. This potassium loss can result in lower-than-normal levels of potassium in the body, leading to hypokalemia.
