1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. A client has a new prescription for Digoxin to treat heart failure. Which of the following findings should the nurse monitor as an adverse effect?

• A. Visual disturbances
• B. Dry cough
• C. Confusion
• D. Urinary retention

Correct answer: A

Rationale: Visual disturbances, such as blurred or yellow vision, can be an early sign of digoxin toxicity. Monitoring for visual changes is crucial to detect and prevent potential adverse effects of digoxin. Dry cough, confusion, and urinary retention are not commonly associated adverse effects of digoxin and are not typically monitored in relation to this medication.

3. A healthcare provider is caring for four clients who have Peptic Ulcer Disease. The healthcare provider should recognize Misoprostol is contraindicated for which of the following clients?

• A. A client who is pregnant
• B. A client who has osteoarthritis
• C. A client who has a kidney stone
• D. A client who has a urinary tract infection

Correct answer: A

Rationale: Misoprostol is contraindicated in pregnancy due to its potential to induce labor. It is used to prevent ulcers in patients taking nonsteroidal anti-inflammatory drugs and is not indicated for osteoarthritis, kidney stones, or urinary tract infections. Therefore, the correct answer is A. Misoprostol should not be used in pregnant individuals as it can cause uterine contractions and potentially harm the fetus. Choices B, C, and D are incorrect as Misoprostol is not contraindicated for clients with osteoarthritis, kidney stones, or urinary tract infections.

4. When administering medications to a 4-month-old infant, which of the following pharmacokinetic principles should be considered? (Select all that apply.)

• A. Infants have a more rapid gastric emptying time.
• B. Infants have immature liver function.
• C. Infants' blood-brain barrier is poorly developed.
• D. Infants have an increased ability to absorb topical medications.

Correct answer: B

Rationale: When administering medications to a 4-month-old infant, the pharmacokinetic principle to consider is that infants have immature liver function until 1 year of age. This requires medications metabolized by the liver to be administered in smaller dosages. While infants do have a more rapid gastric emptying time, immature liver function is a more critical pharmacokinetic consideration in this context. Additionally, although infants have a poorly developed blood-brain barrier, this relates more to pharmacodynamic effects rather than pharmacokinetic principles. The statement about infants having an increased ability to absorb topical medications is not directly related to pharmacokinetic principles, making choice B the correct answer.

5. A healthcare provider is reviewing the health care record of a client who is asking about conjugated equine estrogens. The provider should inform the client this medication is contraindicated in which of the following conditions?

• A. Atrophic vaginitis
• B. Dysfunctional uterine bleeding
• C. Osteoporosis
• D. Thrombophlebitis

Correct answer: D

Rationale: Conjugated equine estrogens are contraindicated in clients with a history of thrombophlebitis due to the increased risk of thrombotic events associated with estrogen use. Thrombophlebitis is characterized by inflammation of a vein with the formation of a clot, and estrogen can further exacerbate this condition, leading to serious complications. Choices A, B, and C are not contraindications for conjugated equine estrogens. Atrophic vaginitis and osteoporosis are conditions where estrogen therapy may actually be indicated. Dysfunctional uterine bleeding is another condition where estrogen therapy can be used to help regulate menstrual bleeding.
