Dopamine receptors

Beta adrenergic receptors

Muscarinic receptors

Alpha adrenergic receptors

Answer and Explanation

The Correct Answer is C

A. Dopamine receptors: Dopamine receptors are involved in the regulation of movement and mood but are not the primary receptors affected by oxybutynin.

B. Beta adrenergic receptors: Beta adrenergic receptors are involved in smooth muscle relaxation, but oxybutynin targets the muscarinic receptors.

C. Muscarinic receptors: Oxybutynin works by blocking muscarinic receptors in the bladder, thereby reducing overactive bladder symptoms like urgency and frequency.

D. Alpha adrenergic receptors: These receptors are involved in vasoconstriction and are not the primary target of oxybutynin.

Correct Answer is A

Explanation

A. Urinalysis: This is the most important test for diagnosing a urinary tract infection (UTI). A urinalysis can reveal the presence of bacteria, white blood cells, and other indicators of infection.

B. Chest X-ray: A chest X-ray is not relevant for diagnosing a UTI and is typically used to assess the lungs.

C. Blood culture: Blood cultures are not routinely performed for a simple UTI unless the infection is suspected to be severe or has spread to the bloodstream.

D. Complete blood count (CBC): While a CBC may show an elevated white blood cell count in the presence of infection, it is not the primary test to confirm a UTI.

A. To measure the pH level of the urine B. To check for the presence of blood in the urine C. To assess kidney function D. To determine the specific bacteria causing the infection

Correct Answer is D

Explanation

A. To measure the pH level of the urine: Urine pH can be useful in certain conditions but is not the primary reason for culture and sensitivity.

B. To check for the presence of blood in the urine: Although blood may be present in urine during a UTI, this is not the primary reason for obtaining a culture and sensitivity.

C. To assess kidney function: While kidney function may be assessed via other tests, culture and sensitivity focus on identifying the causative bacteria in a UTI.

D. To determine the specific bacteria causing the infection: A urine culture and sensitivity test helps identify the specific bacteria causing the UTI and determine the most effective antibiotic treatment.
