A nurse is reviewing the laboratory results of a client who was hyperventilating during a panic attack.
Which of the following arterial blood gas values should the nurse expect?

Choice A rationale:

The nurse should include the statement, "Lifelong treatment with this medication is necessary.”. This is because rifampin is often part of a multidrug regimen used to treat tuberculosis, and treatment typically lasts for several months, sometimes up to a year. It is crucial for the client to understand the need for long-term treatment to ensure the successful eradication of the tuberculosis bacteria from their system.

Choice B rationale:

The statement, "The medication causes amenorrhea if taken along with an oral contraceptive," is not accurate. Rifampin is known to interact with oral contraceptives, decreasing their effectiveness, but it does not directly cause amenorrhea. The correct teaching should focus on the need for alternative or additional contraceptive methods while taking rifampin.

Choice C rationale:

The statement, "You should wear glasses instead of contacts while taking this medication," is not directly related to rifampin. Rifampin can cause certain ocular side effects, but it does not necessarily require the client to switch from contacts to glasses. This advice would depend on the individual's eye health and any specific concerns.

Choice D rationale:

The statement, "A yellow tint to the skin is an expected reaction to the medication," is incorrect. While rifampin can cause a harmless side effect of orange-red discoloration of body fluids, such as urine, sweat, and tears, it does not typically cause a yellow tint to the skin. The nurse should clarify this misconception with the client.

Choice A rationale:

Taking hydrochlorothiazide on an empty stomach is not a requirement for this medication. Hydrochlorothiazide is a diuretic used to treat conditions like hypertension and edema. It can be taken with or without food, and food may help reduce stomach upset for some individuals.

Choice B rationale:

Muscle weakness is an adverse effect of hydrochlorothiazide. Therefore, it is not an expected outcome. Hydrochlorothiazide is a thiazide diuretic, and one of its common side effects is potassium loss through increased urine output. This can lead to muscle weakness and cramping. The nurse should educate the client about the signs and symptoms of low potassium and the importance of including potassium-rich foods in their diet.

Choice C rationale:

Increasing daily intake of foods high in potassium is essential information to include in the teaching for a client taking hydrochlorothiazide. Thiazide diuretics like hydrochlorothiazide can cause potassium depletion, which may result in adverse effects like muscle weakness, cramping, and cardiac dysrhythmias. Therefore, advising the client to consume potassium-rich foods, such as bananas, oranges, and potatoes, can help counteract the potassium loss associated with the medication.

Choice D rationale:

Taking the medication at bedtime is not a specific requirement for hydrochlorothiazide. Thiazide diuretics can be taken at various times of the day, depending on the client's preferences and when they are most compliant with their medication regimen. The timing of administration should be consistent to maintain the medication's effectiveness.
