1. Which is NOT a characteristic or function of lipids?
- A. Involved in energy metabolism and storage
- B. Provide insulation and protection
- C. Act as hormones that regulate the body
- D. Are hydrophilic
Correct answer: D
Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.
2. A client has a new prescription for Ranitidine. Which of the following instructions should the nurse include?
- A. Take the medication with an antacid.
- B. Avoid drinking coffee while taking this medication.
- C. Take the medication at bedtime.
- D. Stop the medication if you develop a headache.
Correct answer: C
Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at bedtime as it helps decrease the production of stomach acid during the night, providing optimal relief for conditions like heartburn or acid indigestion.
3. A nurse is reviewing the medical record of a client who has chronic kidney disease. The client's potassium level is 6.5 mEq/L. Which of the following actions should the nurse take?
- A. Administer sodium bicarbonate
- B. Administer sodium polystyrene sulfonate
- C. Administer calcium gluconate
- D. Administer calcium carbonate
Correct answer: B
Rationale: The correct answer is B: Administer sodium polystyrene sulfonate. Sodium polystyrene sulfonate is used to treat hyperkalemia by promoting the excretion of potassium. Choice A, administering sodium bicarbonate, is incorrect as it is not used to treat hyperkalemia. Choice C, administering calcium gluconate, is incorrect as it is used to treat hypocalcemia, not hyperkalemia. Choice D, administering calcium carbonate, is incorrect as it is used to treat conditions like osteoporosis and indigestion, not hyperkalemia.
4. A healthcare professional is preparing to administer clindamycin 200 mg by intermittent IV bolus. The amount available is clindamycin injection 200 mg in 100 mL 0.9% sodium chloride (0.9% NaCl) to infuse over 30 min. How many mL/hr should the IV pump be set to deliver?
- A. 200 mL/hr
- B. 150 mL/hr
- C. 100 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. Therefore, the IV pump should be set to deliver 200 mL/hr to administer clindamycin 200 mg over 30 minutes. Choice A is correct because it provides the accurate flow rate needed for the administration of the medication. Choices B, C, and D are incorrect as they do not calculate the flow rate correctly based on the volume and time specified in the question.
5. A client is to receive thrombolytic therapy. Which of the following factors should be recognized as a contraindication to the therapy?
- A. Hip arthroplasty 2 weeks ago
- B. Elevated sedimentation rate
- C. Incident of exercise-induced asthma 1 week ago
- D. Elevated platelet count
Correct answer: Hip arthroplasty 2 weeks ago
Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.
