The patient has been prescribed acyclovir.
The nurse is aware that acyclovir is useful to treat which infection?

Choice A rationale

As individuals age, the kidneys' ability to concentrate urine declines due to structural and functional changes in the renal tubules and collecting ducts, including decreased response to antidiuretic hormone. This diminished concentrating ability often leads to an increased excretion of dilute urine, rather than enhanced concentration.

Choice B rationale

Normal physiological changes of aging affecting the urinary system include decreased bladder capacity, decreased bladder muscle tone, and increased involuntary bladder contractions. These changes often result in symptoms such as urinary frequency (more frequent voiding), urgency (sudden strong urge to void), and nocturia (waking up at night to urinate).

Choice C rationale

In healthy adults, the kidneys are typically not easily palpable unless they are enlarged due to pathology, such as polycystic kidney disease or hydronephrosis. Normal kidneys are protected by the lower ribs and posterior abdominal muscles, making deep palpation challenging for identification of normal size.

Choice D rationale

While some older adults may experience increased urinary incontinence due to age-related changes or comorbidities, it is not an inevitable outcome of aging that all patients will require wearing a brief at all times. Many older adults maintain continence with proper management, exercise, and lifestyle modifications, thus avoiding dependence on briefs.

Choice A rationale

While deficits in mobility can indirectly impact urinary habits, leading to issues like delayed toileting, they are not a primary physiological cause of the specific symptoms of frequency, retention, and dribbling in an elderly male. These symptoms often stem from underlying anatomical or functional changes within the genitourinary system itself.

Choice B rationale

Prostate enlargement, specifically benign prostatic hyperplasia (BPH), is a very common condition in elderly males. The enlarged prostate gland compresses the urethra, leading to increased urinary frequency due to bladder irritation, urinary retention due to outflow obstruction, and dribbling as a result of incomplete bladder emptying. This is a direct physiological cause.

Choice C rationale

While some changes in urinary patterns can occur with aging, urinary retention and dribbling are not considered "normal" symptoms. They indicate a potential underlying pathology requiring investigation, not just an expected part of the aging process. Normal aging might involve slight increases in frequency but not significant retention.

Choice D rationale

Coughing or sneezing can sometimes lead to stress incontinence in individuals with weakened pelvic floor muscles, resulting in involuntary urine leakage. However, this differs from the symptoms of urinary retention and dribbling, which are more indicative of an obstructive process within the urinary tract.
