A healthcare professional is teaching a client about the use of methotrexate. Which of the following should be included?

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for signs of infection.' Methotrexate can suppress the immune system, making the client more susceptible to infections. Educating the client to monitor for signs of infection is crucial for early detection and management. Choice A is incorrect because methotrexate is not a pain reliever; it is commonly used to treat conditions like cancer, rheumatoid arthritis, and psoriasis. Choice C is incorrect because methotrexate is usually recommended to be taken with food to reduce gastrointestinal side effects. Choice D is incorrect because methotrexate is known to be harmful during pregnancy and should not be used by pregnant individuals as it can cause birth defects.

Correct Answer: C

Rationale: Edema is a common sign of fluid overload. When the body retains more fluid than it excretes, it can lead to edema, which is swelling caused by excess fluid trapped in body tissues. Weight gain, not weight loss, is typically associated with fluid overload due to the retained fluids. Decreased blood pressure is more commonly associated with dehydration rather than fluid overload. Increased urine output is a sign of the body trying to eliminate excess fluids, which is contrary to the signs of fluid overload.

Correct Answer: B

Rationale: The correct answer is B: 'Use of accessory muscles.' Clients with COPD often experience airway obstruction, leading to the use of accessory muscles to breathe. This compensatory mechanism helps them overcome the increased work of breathing. Choice A, 'Decreased respiratory rate,' is incorrect because clients with COPD typically have an increased respiratory rate due to the need for more effort to breathe. Choice C, 'Improved lung sounds,' is incorrect because COPD is characterized by wheezes, crackles, and diminished breath sounds. Choice D, 'Increased energy levels,' is incorrect because clients with COPD often experience fatigue due to the increased work of breathing and impaired gas exchange.

Correct Answer: B

Rationale: Correct Answer: Dilute the medication. Potassium chloride should always be diluted before administration to avoid irritation and complications. Choice A is incorrect because administering it as a bolus can lead to adverse effects. Choice C is incorrect as giving it rapidly can be dangerous. Choice D is incorrect as monitoring the respiratory rate is not directly related to administering potassium chloride.

Correct Answer: B

Rationale: The correct answer is to take metformin with food. This is important to minimize gastrointestinal side effects and improve absorption. Choice A is incorrect as metformin is not typically associated with weight gain. Choice C is wrong as metformin is not an insulin but a medication that helps control blood sugar levels. Choice D is also incorrect as metformin is not known to cause hyperglycemia.
