1. A drug ending in the suffix (azole) is considered a ______.
- A. H
- B. ACE inhibitor
- C. Antifungal
- D. Beta agonist
Correct answer: C
Rationale: Drugs ending in the suffix -azole are commonly associated with antifungal medications. Examples include fluconazole, ketoconazole, and itraconazole. These medications are used to treat fungal infections by inhibiting the growth of fungi. Therefore, the correct answer is option C, 'Antifungal'. Options A, B, and D do not accurately describe drugs ending in -azole.
2. A client is taking Epoetin Alfa for anemia. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. White blood cell count
- B. Platelet count
- C. Hematocrit
- D. Serum potassium level
Correct answer: C
Rationale: The nurse should monitor the hematocrit level to evaluate the effectiveness of Epoetin Alfa therapy. Epoetin Alfa stimulates red blood cell production, leading to an increase in hematocrit levels. Monitoring the hematocrit helps assess the response to therapy and ensures that the medication is effectively addressing the anemia. White blood cell count and platelet count are not directly affected by Epoetin Alfa therapy. Serum potassium level monitoring is important for other medications that may impact potassium levels but is not specifically relevant to assessing the effectiveness of Epoetin Alfa in treating anemia.
3. A healthcare professional is caring for a client who is receiving heparin therapy. Which of the following laboratory tests should the healthcare professional monitor to evaluate the therapeutic effect of heparin?
- A. PT/INR
- B. Platelet count
- C. aPTT
- D. WBC count
Correct answer: C
Rationale: The correct test to monitor the therapeutic effect of heparin is the activated partial thromboplastin time (aPTT). Heparin's action is to prolong the clotting time, and aPTT reflects this effect. Monitoring aPTT helps ensure that the client is within the therapeutic range to prevent clot formation while minimizing the risk of bleeding complications. PT/INR is used to monitor warfarin therapy, platelet count assesses for potential thrombocytopenia, and WBC count evaluates for signs of infection or inflammation, not the therapeutic effect of heparin.
4. A client has a new prescription for Albuterol and Beclomethasone inhalers for the control of asthma. Which of the following instructions should the nurse include in the teaching?
- A. Take the albuterol at the same time each day.
- B. Administer the albuterol inhaler prior to using the beclomethasone inhaler.
- C. Use beclomethasone if experiencing an acute episode.
- D. Avoid shaking the beclomethasone before use.
Correct answer: B
Rationale: When a client is prescribed an inhaled beta2-agonist, such as albuterol, and an inhaled glucocorticoid, such as beclomethasone, for asthma control, the beta2-agonist should be administered first. This sequence is important because the beta2-agonist promotes bronchodilation, which enhances the absorption and effectiveness of the glucocorticoid. Instructing the client to administer the albuterol inhaler before using the beclomethasone inhaler ensures optimal therapeutic benefit. Therefore, option B is the correct choice. Option A is incorrect because the timing of albuterol administration may vary based on the prescribed regimen. Option C is incorrect because beclomethasone is a controller medication, not a rescue medication, and should not be used during acute episodes. Option D is incorrect because beclomethasone should be shaken before use to ensure proper dispersion of the medication.
5. When taking Digoxin, low levels of what can cause toxicity?
- A. Potassium
- B. Calcium
- C. Sodium
- D. Magnesium
Correct answer: A
Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.
