Correct Answer: B

Rationale: The correct answer is to take levothyroxine at the same time every day. Consistent timing helps maintain stable thyroid levels, ensuring the effectiveness of the medication. It is important to establish a routine to optimize its therapeutic benefits. Choice A is incorrect as patients should not ignore side effects but should consult healthcare professionals if they experience any. Choice C is incorrect because thyroid tests may still be necessary to monitor thyroid function while on levothyroxine. Choice D is incorrect as it is not advisable to take levothyroxine if the patient has recently had a myocardial infarction without consulting their healthcare provider.

Correct Answer: B

Rationale: The correct answer is B. Visual changes, such as yellow or blurred vision, can be indicative of digoxin toxicity. It is crucial for clients to inform their healthcare provider promptly if they encounter these symptoms. Prompt medical attention can help manage potential toxicity and prevent complications.

Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility.

Correct Answer: C

Rationale: In treating a Cerebrospinal fluid infection caused by gram-negative bacteria, Cefepime, a fourth-generation cephalosporin, is the most suitable choice due to its enhanced efficacy against gram-negative organisms in such infections. Cefaclor (Choice A) is a second-generation cephalosporin more commonly used for respiratory tract infections. Cefazolin (Choice B) is a first-generation cephalosporin often used for skin and soft tissue infections. Cephalexin (Choice D) is a first-generation cephalosporin indicated for skin and urinary tract infections, but not the optimal choice for a Cerebrospinal fluid infection with gram-negative bacteria.
