A patient has a urinary tract infection.
The nurse knows that which class of drugs is especially useful for such infections?

Choice A rationale:

Bounding peripheral pulses are not typically associated with diabetes insipidus. Diabetes insipidus is a condition characterized by excessive thirst and excretion of large amounts of severely dilute urine.

Choice B rationale:

Moist mucous membranes are not a common finding in diabetes insipidus. In fact, due to excessive urination, patients may experience dehydration which can lead to dry mucous membranes.

Choice C rationale:

Bradycardia, or a slower than normal heart rate, is not a typical symptom of diabetes insipidus. The condition does not directly affect the heart rate.

Choice D rationale:

Decreased urine specific gravity is a key finding in diabetes insipidus. The condition causes an imbalance of water in the body, leading to the production of large amounts of dilute (or low specific gravity) urine.

Please note that these rationales are based on general knowledge about diabetes insipidus and the specific symptoms mentioned in the choices. For a more detailed understanding, it’s recommended to refer to medical textbooks or consult with healthcare professionals.

Choice A rationale:

While it’s important for the client’s family to be aware of the disease and take precautions, they do not necessarily need to take medications to prevent infection. Tuberculosis (TB) is a contagious disease, but it typically requires close and prolonged contact to spread. Family members should be tested for TB, and if they test positive, then treatment would be necessary.

Choice B rationale:

This is the correct answer. A typical course of treatment for TB involves 6 to 9 months of consistent medication use. This is because TB bacteria die very slowly, and medications need to be taken for several months to ensure that all the bacteria are killed. If treatment is stopped too soon, some bacteria may survive and become resistant to the drugs.

Choice C rationale:

It’s not accurate to say that medications will need to be taken for the rest of the client’s life. While TB treatment is lengthy, it does not continue indefinitely. Once the full course of treatment is completed and the disease is cured, further medication is not typically necessary.

Choice D rationale:

The Mantoux test, also known as the tuberculin skin test, is used to determine whether a person has TB infection. However, the test can remain positive for a long time, even after successful treatment. Therefore, medications should not be taken until the Mantoux test is negative. Instead, the duration of treatment is determined by the healthcare provider based on various factors, including the patient’s response to the medication.
