A nurse is caring for a client who has tuberculosis and is taking isoniazid and rifampin. Which of the following outcomes indicates that the client is adhering to the medication regimen?
The client has a negative sputum culture.
The client tests negative for HIV.
The client's liver function test results are within the expected reference range.
The client has a positive purified protein derivative test
The Correct Answer is A
A. The client has a negative sputum culture.
When a client with tuberculosis is adhering to the prescribed medication regimen, their sputum cultures should show a decrease in the number of Mycobacterium tuberculosis bacteria. This indicates that the medication is effectively treating the infection. It's important for clients with tuberculosis to complete their full course of treatment to prevent drug-resistant strains of the bacteria from developing.
B. The client tests negative for HIV: This relates to a different infection (HIV) and doesn't necessarily reflect adherence to the tuberculosis medication regimen.
C. The client's liver function test results are within the expected reference range: While liver function tests are important to monitor due to potential medication side effects, they don't directly indicate medication adherence.
D. The client has a positive purified protein derivative (PPD) test: A positive PPD test indicates exposure to the tuberculosis bacteria in the past but does not reflect current adherence to treatment.

Correct Answer is D
Explanation
A. Decrease in protein:
This choice is incorrect. Albumin is a protein found in the blood, and when a client is receiving an infusion of albumin, it is likely to increase, not decrease, the overall protein level in the bloodstream. Albumin infusions are often given to help increase plasma oncotic pressure and improve fluid retention in conditions like shock.
B. Oxygen saturation 96%:
This choice is incorrect. Oxygen saturation of 96% is within the normal range and reflects adequate oxygenation. It doesn't directly relate to the administration of albumin in shock.
C. PaCO2 30 mm Hg:
This choice is incorrect. The partial pressure of carbon dioxide (PaCO2) of 30 mm Hg reflects a respiratory value and doesn't directly relate to the administration of albumin or the management of shock. It's important for assessing acid-base balance, but it's not a specific finding related to the albumin infusion.
D. Increase in BP:
This is the correct choice. Albumin is a colloid solution that helps increase the oncotic pressure within blood vessels, which can contribute to an increase in blood volume. When blood volume increases, it can lead to an increase in blood pressure, which is a desired effect in the management of shock. Increasing blood pressure helps improve perfusion to vital organs and tissues, which is essential in shock situations.
Correct Answer is A
Explanation
A. Estrogen-progestin combination:
Correct Answer: This medication interacts with carbamazepine.
Explanation: Carbamazepine is known to induce certain liver enzymes, including cytochrome P450 enzymes. These enzymes play a role in the metabolism of various medications, including estrogen-containing oral contraceptives (estrogen-progestin combinations). Carbamazepine can increase the metabolism of estrogen-progestin combinations, potentially reducing their effectiveness and increasing the risk of contraceptive failure. Therefore, this interaction can lead to decreased contraceptive efficacy and the potential for unintended pregnancy.
B. Nicotine transdermal system:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Nicotine replacement therapies, such as nicotine transdermal systems, are not known to have significant interactions with carbamazepine. These therapies are primarily used to aid in smoking cessation and do not share metabolic pathways with carbamazepine.
C. Diphenhydramine:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Diphenhydramine is an antihistamine used for allergies and as a sleep aid. It does not have a well-established interaction with carbamazepine. However, it's important to note that carbamazepine can have central nervous system (CNS) effects, so caution should be exercised when combining it with other medications that also have CNS effects.
D. Beclomethasone:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Beclomethasone is a corticosteroid used to manage inflammation associated with conditions like asthma and allergic rhinitis. It is not known to interact with carbamazepine. These two medications have different mechanisms of action and do not share significant metabolic pathways.
