LPN Pharmacology Practice Test

Correct Answer: A

Rationale: The correct answer is A: 'You may experience weight gain.' Prednisone commonly causes weight gain as a side effect, so it is important for the client to be aware of this potential outcome. Monitoring weight changes can be essential in managing the medication's effects and overall health. Choices B, C, and D are incorrect. Increasing vitamin K intake is not specifically related to prednisone use. Expecting increased urinary output is not a common side effect of prednisone. Dark, tarry stools are more commonly associated with gastrointestinal bleeding rather than prednisone use.

Correct Answer: B

Rationale: The correct answer is to instruct the client to report any signs of bleeding when taking warfarin. Warfarin is an anticoagulant medication that increases the risk of bleeding, so it is essential to monitor for any signs of abnormal bleeding and report them promptly for appropriate management. Choices A, C, and D are incorrect. Instructing the client to avoid using a soft toothbrush is not directly related to warfarin therapy. Increasing the intake of leafy green vegetables is not recommended as they contain vitamin K, which can interfere with warfarin's anticoagulant effects. Taking warfarin with food can be inconsistent and may not result in optimal absorption.

Correct Answer: C

Rationale: The correct answer is C: 'Monitor your pulse rate daily.' Monitoring the pulse rate daily is crucial when taking digoxin as it helps in early detection of digoxin toxicity. Digoxin can cause toxicity, which may manifest as changes in the heart rate, making monitoring the pulse rate an essential part of managing the medication. It is important for the client to be aware of their normal pulse rate and report any significant changes to their healthcare provider promptly. Choices A, B, and D are incorrect. Taking digoxin at bedtime is not a specific instruction related to monitoring its effects. Avoiding antacids is relevant for some medications, but not a key concern with digoxin. Increasing potassium-rich foods may interact with digoxin due to its effect on potassium levels, but monitoring the pulse rate is a more direct and immediate need for safety.

Correct Answer: A

Rationale: The correct answer is A: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to ensure optimal absorption. Food, especially high-fiber foods, can interfere with the absorption of levothyroxine. Taking it with an antacid or at bedtime may also affect its absorption. Instructing the client to take the medication on an empty stomach will help maintain consistent blood levels of levothyroxine. Choice B is incorrect as taking levothyroxine with food can reduce its absorption. Choice C is incorrect because taking levothyroxine at bedtime may lead to inconsistent blood levels due to food intake during the day. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.

Correct Answer: A

Rationale: The correct answer is A, Cefoxitin. Cefoxitin can contain latex in the stopper of the vial, which may pose a risk for allergic reaction in individuals with latex sensitivity. Amoxicillin, Erythromycin, and Metronidazole do not typically contain latex components in their formulations. Healthcare providers should be vigilant in identifying and avoiding medications with latex components to prevent adverse reactions in patients with known latex allergies.
