1. A client with osteoporosis is prescribed raloxifene. The nurse should reinforce which instruction?
- A. Take this medication at the same time each day.
- B. Take this medication with a full glass of water.
- C. Take this medication on an empty stomach.
- D. Take this medication immediately after a meal.
Correct answer: A
Rationale: The correct instruction for a client prescribed raloxifene, a medication used for osteoporosis, is to take it at the same time each day. This consistency helps maintain steady blood levels of the medication, enhancing its effectiveness in managing the condition. Choice B is incorrect because raloxifene does not require a full glass of water for administration. Choice C is incorrect as raloxifene should not be taken on an empty stomach. Choice D is incorrect as raloxifene should not be taken immediately after a meal.
2. The healthcare provider notes that a client has a new prescription for 20 mEq of potassium. The IV site is inflamed but not tender, and has a blood flashback. What action should the healthcare provider take?
- A. Obtain a liter of normal saline with 20 mEq of KCl
- B. Contact the healthcare provider to clarify the prescription
- C. Withhold the prescription medication until a new IV is started
- D. Fax the prescription to the pharmacy for immediate dispensing
Correct answer: B
Rationale: The healthcare provider should contact the prescriber to clarify the prescription because an inflamed IV site may indicate potential issues with administering the medication. It is important to ensure that the prescription is appropriate and safe for the client before proceeding with administration. Option A is incorrect because administering potassium through an inflamed IV site can lead to further complications. Option C is not the best course of action as clarifying the prescription first is essential. Option D is also incorrect as the focus should be on ensuring the safety of the client before dispensing the medication.
3. A client undergoing hemodialysis for chronic kidney disease is taking the medication erythropoietin. The nurse should reinforce instructions to explain for which reason this medication is prescribed?
- A. This drug prevents infections associated with dialysis.
- B. This drug prevents deep vein thrombosis in older clients.
- C. This drug helps stimulate the production of red blood cells.
- D. This drug helps balance the level of phosphorus in the body.
Correct answer: C
Rationale: Erythropoietin is prescribed to stimulate the production of red blood cells. Clients undergoing hemodialysis often develop anemia due to end-stage renal disease. Erythropoietin helps correct this anemia by stimulating red blood cell production. It is not used to prevent infections associated with dialysis, prevent deep vein thrombosis, or balance phosphorus levels in the body.
4. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?
- A. Midway through administration of the IV dose and 30 minutes before the next
- B. Two hours after completion of the IV dose and 30 minutes before the next
- C. Two hours after completion of the IV dose and one hour before the next
- D. Immediately after completion of the IV dose and 30 minutes before
Correct answer: B
Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.
5. The practical nurse administered 15 units of NPH insulin subcutaneously to a client before they consumed their breakfast at 7:30 AM. At what time is the client at an increased risk for a hypoglycemic reaction?
- A. 8:30 to 11:30 AM
- B. 3:30 to 7:30 PM
- C. 9:30 PM to midnight
- D. 1:00 to 5:00 AM
Correct answer: B
Rationale: NPH insulin, an intermediate-acting type, peaks approximately 8 to 12 hours after subcutaneous administration. Considering this, the client is most likely to experience a hypoglycemic reaction between 3:30 and 7:30 PM, making option B the correct answer. Choices A, C, and D are incorrect because they fall outside the peak time for a hypoglycemic reaction after administering NPH insulin.
