A nurse is caring for a client who has a new diagnosis of tuberculosis (TB). The client asks the nurse why she needs to take four different antituberculotic medications. Which of the following replies should the nurse make?
"The organism that causes TB becomes resistant to antituberculotic medications when you only take one medication."
Taking several antituberculotic medications will protect your liver from toxic effects."
"People who have a severe form of TB need several antituberculotic medications, but those who have less severe TB need just one medication."
"Adverse effects occur more often and are more severe when you take only one antituberculotic medication."
The Correct Answer is A
Choice A Reason:
"The organism that causes TB becomes resistant to antituberculotic medications when you only take one medication." This statement is appropriate.
Tuberculosis bacteria tend to develop resistance to single medications when used alone. Using multiple medications simultaneously helps prevent the bacteria from becoming resistant to any single drug. This strategy, known as combination therapy, is crucial in treating TB effectively and reducing the risk of drug resistance.
When TB bacteria are exposed to just one medication, they can mutate and become resistant to that specific drug. However, using a combination of medications helps ensure that if one medication fails to eliminate some bacteria due to resistance, the other drugs can still work against the resistant strains.
Preventing drug resistance is essential for successful TB treatment and to avoid the need for more complex and less effective medications if resistance develops.
Choice B Reason:
"Taking several antituberculotic medications will protect your liver from toxic effects." This statement is incorrect. While it's true that some antituberculotic medications can have hepatotoxic effects (adverse effects on the liver), the primary reason for using multiple medications in TB treatment isn't solely to protect the liver. The main goal of using multiple medications is to prevent the development of drug-resistant strains of TB bacteria. Protecting the liver is an important consideration in medication selection and monitoring but isn't the primary rationale for multiple medications.
Choice C Reason:
"People who have a severe form of TB need several antituberculotic medications, but those who have less severe TB need just one medication." This statement is incorrect. The severity of TB doesn't determine the number of medications required. The standard treatment approach for TB involves multiple medications, regardless of the severity. This approach aims to prevent the development of drug resistance, ensure effective treatment, and reduce the risk of treatment failure. Using a combination of medications is a fundamental strategy to combat TB effectively.
Choice D Reason:
"Adverse effects occur more often and are more severe when you take only one antituberculotic medication." This statement is incorrect. While it's true that adverse effects can occur with antituberculotic medications, the primary reason for using multiple medications isn't solely to reduce adverse effects. The main concern addressed by using multiple drugs is preventing the development of drug-resistant TB strains. Using a combination of medications reduces the likelihood of resistance developing and increases the effectiveness of treatment, rather than solely minimizing adverse effects.

Correct Answer is A
Explanation
Choice A Reason:
Administering a prescribed oral dose of trazodone to the client is correct. Trazodone is sometimes used to manage agitation in patients with Alzheimer's disease, as it has calming effects and can help reduce agitation and anxiety. However, the use of any medication should be based on the client's individualized treatment plan and prescribed by a healthcare provider.
Choice B Reason:
Encouraging ambulation might not be suitable if the client is agitated, as it could potentially escalate the situation or increase the risk of falls or injury. Safety should be a priority, and ambulation might not be advisable during a state of agitation.
Choice C Reason:
Isolating the client in their room is incorrect. Isolating the client might increase feelings of confusion, fear, or distress, potentially worsening the agitation. It's important to engage and support the client rather than isolate them, which can be distressing for someone with Alzheimer's disease.
Choice D Reason:
Applying bilateral wrist restraints to the client is incorrect. The use of restraints should only be considered as a last resort when all other measures have failed and when there's an immediate risk of harm to the client or others. Restraints can be physically and psychologically harmful, leading to increased agitation, anxiety, and potential injury. They should be used only under strict guidelines and with proper authorization when all other interventions have been exhausted.
Correct Answer is C
Explanation
Choice A Reason:
Administer meperidine IM is incorrect. Reason why it's not the answer: Meperidine (Demerol) is not recommended in cases of malignant hyperthermia. It can potentially exacerbate the situation by further increasing muscle rigidity and potentially contributing to the hypermetabolic state. Meperidine can trigger additional release of calcium from the sarcoplasmic reticulum in muscles, worsening the symptoms.
Choice B Reason:
Instill a warm enema solution is incorrect. Reason why it's not the answer: Introducing warm solutions can exacerbate the client's condition by further increasing body temperature. Malignant hyperthermia is characterized by a dangerous increase in body temperature, and adding heat through an enema would only make the situation worse.
Choice C Reason:
Applying a cooling blanket is recommendable. Reason why it's the answer: A cooling blanket is a recommended intervention for managing malignant hyperthermia. Lowering the body temperature is crucial in preventing further complications associated with the high fever. Cooling blankets help dissipate heat from the body, aiding in rapidly reducing the dangerously elevated temperature associated with malignant hyperthermia.
Choice D Reason:
Ventilate client with 50% oxygen is incorrect. Reason why it's not the answer: While providing oxygen support might be necessary as part of managing the overall condition, ventilating with 50% oxygen specifically may not directly address the core issue of rapidly cooling the body during a malignant hyperthermia crisis. Ventilation may be required, but the immediate concern is to cool the body to prevent complications arising from the elevated body temperature.
