1. Which of the following types of insulin is classified as 'long-acting'?
- A. Lispro (Humalog)
- B. NPH (Humulin N)
- C. Regular insulin (Humulin R)
- D. Glargine (Lantus)
Correct answer: D
Rationale: The correct answer is Glargine (Lantus). Glargine is classified as a long-acting insulin due to its slow, steady release over an extended period, making it suitable for basal insulin requirements. It has a duration of action that can last up to 24 hours, helping to maintain stable blood sugar levels throughout the day. Lispro (Humalog) is a rapid-acting insulin, NPH (Humulin N) is an intermediate-acting insulin, and Regular insulin (Humulin R) is a short-acting insulin, so they are not classified as long-acting insulins.
2. A client has a new prescription for Omeprazole. Which of the following instructions should the nurse include?
- A. Take this medication before meals.
- B. Take this medication with food.
- C. Take this medication at bedtime.
- D. Take this medication with antacids.
Correct answer: A
Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that should be taken before meals to be most effective in reducing stomach acid production. Taking it before meals allows the medication to inhibit the proton pumps in the stomach when they are most active, leading to better control of acid secretion. Choice B is incorrect because taking Omeprazole with food may reduce its effectiveness as food can interfere with its absorption. Choice C is incorrect as Omeprazole is more effective when taken before meals. Choice D is incorrect as Omeprazole should not be taken with antacids as they can reduce its absorption.
3. A client with deep vein thrombosis has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?
- A. Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.
- B. I will call the provider to get a prescription for discontinuing the IV heparin today.
- C. Both heparin and warfarin work together to dissolve the clots.
- D. The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay.
Correct answer: A
Rationale: The correct answer is A because warfarin takes several days to reach a therapeutic level and exert its full anticoagulant effect. During this time, the IV heparin is continued to prevent clotting until the warfarin is effective. Both medications are used together temporarily for this reason. Discontinuing heparin prematurely can increase the risk of clot formation. Therefore, the nurse should explain to the client that the IV heparin will be continued until the warfarin reaches a therapeutic level.
4. A client has a new prescription for Warfarin. Which of the following instructions should the nurse include?
- A. Avoid consuming foods high in vitamin K.
- B. Monitor your blood pressure regularly.
- C. Increase your intake of green, leafy vegetables.
- D. Take the medication with a high-fat meal.
Correct answer: A
Rationale: The correct answer is to advise the client to avoid consuming foods high in vitamin K. Warfarin's effectiveness can be affected by vitamin K intake. Clients should maintain a consistent intake of vitamin K and avoid sudden increases in foods high in vitamin K to ensure the medication works properly and consistently. Choices B, C, and D are incorrect. Monitoring blood pressure, increasing intake of green, leafy vegetables, or taking the medication with a high-fat meal are not specific instructions related to Warfarin therapy.
5. What finding should a nurse monitor for as an adverse effect when a client has a new prescription for Spironolactone?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is hyperkalemia. Spironolactone is a potassium-sparing diuretic that can lead to an increase in potassium levels. Hyperkalemia can be dangerous, causing muscle weakness and cardiac dysrhythmias. Monitoring potassium levels closely is crucial when a client is on Spironolactone. Hypoglycemia (choice B) is incorrect because Spironolactone does not typically affect blood glucose levels. Hypocalcemia (choice C) and hyponatremia (choice D) are also incorrect as Spironolactone's primary impact is on potassium levels.
