1. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
Correct answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
2. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:
- A. Refrigerates the collected specimen
- B. Collects the specimen in a sterile container
- C. Delays the collection of the specimen
- D. Uses a non-contaminated collection container
Correct answer: A
Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
3. A nurse is caring for a client who has terminal lung cancer. The nurse observes the client’s family assisting with all ADLs. Which of the following rationales for self-care should the nurse communicate to the family?
- A. Allowing the client to function independently will strengthen muscles and promote healing.
- B. The client needs privacy at times for self-reflection and organizing life.
- C. The client’s sense of loss can be lessened through retaining control of some areas of life.
- D. Performing ADLs is a requirement prior to discharge from an acute care facility.
Correct answer: C
Rationale: The correct answer is C. In situations like terminal illness, allowing clients to perform activities of daily living (ADLs) can help maintain their sense of control and dignity, providing comfort and a sense of normalcy amidst their health challenges. Choice A is incorrect because in a terminal stage, the focus is not on muscle strength or promoting physical healing but rather on enhancing the client's emotional well-being. Choice B, while highlighting the importance of privacy, is not directly addressing the client's need for control and autonomy. Choice D is incorrect as the priority in this scenario is not related to discharge requirements but rather the client's emotional and psychological needs during their terminal illness.
4. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:
- A. Cleanse the entry port prior to withdrawing urine.
- B. Use a sterile syringe to collect urine from the collection bag.
- C. Obtain the specimen from the drainage tubing.
- D. Replace the catheter before obtaining the specimen.
Correct answer: A
Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.
5. A client with chronic kidney disease is receiving epoetin alfa (Epogen). Which laboratory value should the LPN/LVN monitor to determine the effectiveness of this medication?
- A. Serum potassium
- B. Hemoglobin
- C. Serum creatinine
- D. Blood urea nitrogen (BUN)
Correct answer: B
Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.
