The client has begun medication therapy with pancrelipase (Pancrease MT). The nurse evaluates that the medication is having the optimal intended benefit if which effect is observed?

Correct Answer: C

Rationale: Pancrelipase (Pancrease MT) is a pancreatic enzyme replacement therapy used to aid digestion in clients with pancreatic insufficiency. One of the key goals of pancrelipase therapy is to reduce the amount of undigested fat in the stool, known as steatorrhea. Therefore, the nurse should evaluate the effectiveness of pancrelipase by looking for a reduction in steatorrhea, indicating improved digestion and absorption of fats.

Correct Answer: B

Rationale: Guaifenesin is an expectorant used to help loosen mucus and make coughs more productive. Taking it with a full glass of water helps decrease the viscosity of secretions, making it easier to expel mucus from the respiratory tract. It is important not to crush sustained-release tablets, as this can alter the intended release of the medication and lead to potential adverse effects.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Causes orange discoloration of sweat, tears, urine, and feces. Rifampin is a medication known to cause this distinctive side effect, which is important for the client to be aware of to prevent unnecessary concern or alarm. Educating the client about this potential side effect promotes understanding and adherence to the prescribed treatment plan. Option A) Should always be taken with food or antacids is incorrect because rifampin is actually best absorbed on an empty stomach, so taking it with food or antacids may reduce its effectiveness. Option B) Should be double-dosed if one dose is forgotten is incorrect because doubling the dose can lead to harmful effects or toxicity. It is essential to adhere to the prescribed dosing schedule and never double up on doses. Option D) May not be discontinued independently if symptoms are gone in 3 months is incorrect because rifampin is often used for long-term therapy, especially in the treatment of conditions like tuberculosis. Discontinuing the medication prematurely can result in treatment failure or the development of drug-resistant strains of bacteria. In the educational context, understanding the side effects, correct administration, and importance of adherence to prescribed medications are crucial aspects of pharmacological education for both healthcare providers and clients to ensure safe and effective treatment outcomes.

Correct Answer: B

Rationale: When a client is stabilized with daily insulin injections, it is crucial to rotate the injection sites systematically. This practice helps prevent the development of lipodystrophy, which can affect insulin absorption and lead to inconsistent glucose control. Additionally, rotating sites minimizes discomfort and tissue damage, ensuring optimal insulin delivery and effectiveness.

Correct Answer: C

Rationale: The correct answer is C. Sildenafil (Viagra) enhances the vasodilating effect of nitric oxide and is contraindicated with the concurrent use of organic nitrates and nitroglycerin.
