The client who has a cold is seen in the emergency room with inability to void. Because the client has a history of BPH, the nurse determines that the client should be questioned about the use of which of the following medications?
A. Diuretics
B. Antibiotics
C. Antitussives
D. Decongestants
Correct Answer: D. Decongestants
In the client with BPH, episodes of urinary retention can be triggered by certain medications, such as decongestants, anticholinergics, and antidepressants. The client should be questioned about the use of these medications if the client has urinary retention. Retention can also be precipitated by other factors, such as alcoholic beverages, infection, bedrest, and becoming chilled.
Option A: Diuretics are drugs that pharmacologically tilt the renal fluid regulation in favor of excretion of water and electrolytes. Thus, diuretics are substances that increase the production and volume of urine. This class of drugs achieves this objective primarily by suppressing receptors that aid in reabsorption of Na+, the most abundant extracellular cation, from the renal tubules, thereby increasing the osmolality of the renal tubules and consequently suppressing water reabsorption.
Option B: Gentamicin is known to cause decreased urine output. If a medication causes a release of less urine, discuss concerns with a doctor. They may change the medication or adjust the current dosage.
Option C: Antitussives are medicines that suppress coughing, also known as cough suppressants. Antitussives are thought to work by inhibiting a coordinating region for coughing located in the brain stem, disrupting the cough reflex arc; although the exact mechanism of action is unknown.
