1. A client is taking Glipizide to treat Diabetes Mellitus. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of this medication?
- A. Cholesterol level.
- B. Hematocrit.
- C. Blood glucose level.
- D. Calcium level.
Correct answer: C
Rationale: The correct answer is C: Blood glucose level. Monitoring the client's blood glucose level is crucial when taking Glipizide, a medication used to lower blood glucose levels in individuals with Diabetes Mellitus. By monitoring the blood glucose level, the nurse can evaluate the effectiveness of the medication in managing the client's condition. Choices A, B, and D are incorrect as they are not directly related to assessing the effectiveness of Glipizide in treating Diabetes Mellitus. Cholesterol level, hematocrit, and calcium level may be important for other aspects of the client's health but are not the primary indicators of Glipizide's effectiveness.
2. What is the therapeutic use of Phenytoin?
- A. Replacement in hypothyroidism to restore normal hormonal balance
- B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
- C. Diminished seizure activity, termination of ventricular arrhythmias
- D. Prevention of thrombus formation, prevention of extension of existing thrombi
Correct answer: C
Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.
3. A patient on a medical-surgical unit administers a hypnotic medication to an older adult client at 2100. The next morning, the client is drowsy and wants to sleep instead of eating breakfast. Which of the following factors should the nurse identify as a possible reason for the client's drowsiness?
- A. Reduced cardiac function
- B. First-pass effect
- C. Reduced hepatic function
- D. Increased gastric motility
Correct answer: C
Rationale: In older adults, reduced hepatic function can lead to prolonged effects of medications metabolized by the liver. This prolonged effect may result in drowsiness the next morning. Adjusting the dosage of the hypnotic medication may be necessary for this client. Choices A, B, and D are incorrect. Reduced cardiac function (Choice A) is not typically associated with drowsiness due to medication effects. The first-pass effect (Choice B) relates to the initial metabolism of a drug in the liver before reaching systemic circulation, which is not directly linked to drowsiness the next morning. Increased gastric motility (Choice D) does not commonly cause drowsiness as described in the scenario.
4. A client has been taking Sertraline for the past 2 days. Which of the following assessment findings should alert the nurse to the possibility that the client is developing Serotonin syndrome?
- A. Bruising
- B. Fever
- C. Abdominal pain
- D. Rash
Correct answer: B
Rationale: The correct answer is B: Fever. Fever is a key symptom of serotonin syndrome, a potentially life-threatening condition that can occur with the use of serotonergic medications like Sertraline. Serotonin syndrome is characterized by a combination of symptoms, including fever, agitation, rapid heartbeat, sweating, shivering, tremors, and in severe cases, it can lead to seizures, coma, and even death. Bruising (Choice A), abdominal pain (Choice C), and rash (Choice D) are not typically associated with serotonin syndrome. Therefore, the nurse should be vigilant in monitoring for fever as an early sign of serotonin syndrome in clients taking Sertraline.
5. A healthcare professional is preparing to administer acetaminophen 650 mg PO every 6 hr PRN for pain. The amount available is acetaminophen liquid 500 mg/5 mL. How many mL should the healthcare professional 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 healthcare professional should administer 6.5 mL of acetaminophen per dose to achieve the desired 650 mg dose for pain relief. Choice A is correct because it accurately calculates the volume required based on the concentration of the liquid acetaminophen. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the concentration of the liquid medication and the desired dose.
