A client is being taught about the use of nitroglycerin. Which of the following should be included?

Correct Answer: B

Rationale: The correct answer is to place the nitroglycerin tablet under the tongue. Nitroglycerin tablets are meant for sublingual absorption during angina episodes to provide quick relief. Option A is incorrect because nitroglycerin should not be taken with food. Option C is incorrect as nitroglycerin should be stored in a cool, dark place, not in the refrigerator. Option D is incorrect because nitroglycerin can have side effects, including headaches, dizziness, and low blood pressure.

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: B

Rationale: The correct answer is to monitor for headaches when taking sildenafil. This medication can cause headaches and other side effects, so it is crucial to inform clients about these potential adverse reactions. Choice A is incorrect because sildenafil should not be taken with nitrates due to the risk of severe hypotension. Choice C is incorrect as sildenafil is a prescription medication, not an over-the-counter one. Choice D is incorrect because sildenafil, like any medication, can have side effects that should be discussed with the client.

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.
