An elderly resident of a long-term care facility frequently wakes up to urinate during the night. What physiological change associated with normal aging could be the cause of this?

Choice A Rationale:
Hemorrhage is not a direct risk associated with antibiotic use and diarrhea. While severe diarrhea can lead to fluid loss and potentially hypovolemia, it's not the most significant risk in this context.
Antibiotics themselves don't typically cause bleeding issues unless they specifically interfere with clotting factors, which isn't common.
The nurse should monitor for signs of bleeding, but it's not the primary concern based on the patient's history of antibiotic use and diarrhea.

Choice B Rationale:
Cardiovascular collapse is a serious complication, but it's not directly linked to antibiotic use and diarrhea. It can occur due to various factors like severe dehydration, electrolyte imbalances, or underlying heart conditions. The nurse should be vigilant for signs of cardiovascular instability, but it's not the most likely risk in this scenario.
Choice C Rationale:
Electrolyte imbalances are a significant concern for patients with diarrhea, especially those on antibiotics. Antibiotics can disrupt the balance of gut bacteria, which play a crucial role in electrolyte absorption. Diarrhea further exacerbates electrolyte loss through fluid loss.
Key electrolytes to monitor include:
Potassium: Essential for nerve and muscle function, including the heart. Low potassium (hypokalemia) can lead to muscle weakness, fatigue, cramps, and potentially heart arrhythmias.
Sodium: Vital for fluid balance and nerve signaling. Low sodium (hyponatremia) can cause confusion, seizures, and coma.
Chloride: Also important for fluid balance and acid-base balance.
Magnesium: Crucial for muscle function, nerve transmission, and energy production. Low magnesium (hypomagnesemia) can cause muscle cramps, tremors, and heart arrhythmias.
The nurse should closely monitor the patient's electrolyte levels and watch for signs of imbalance, such as muscle weakness, fatigue, cramps, confusion, or heart rhythm abnormalities.

Choice D Rationale:
Respiratory paralysis is not a typical risk associated with antibiotic use or diarrhea.
It's more commonly linked to neuromuscular disorders, certain medications, or severe electrolyte imbalances (especially low potassium or calcium).
While the nurse should be aware of potential respiratory complications, it's not the most likely concern in this case.

A. Pale, yellow urine: While pale yellow urine can be a symptom of a UTI, it is not specific enough and can be caused by other factors like dehydration or certain medications. Therefore, it is not a reliable indicator of a UTI in this case.
B. Cloudy urine: Cloudy urine is a more specific symptom of a UTI, as it can indicate the presence of white blood cells or bacteria in the urine. This finding, along with other symptoms, suggests a possible UTI.

C. Suprapubic pain: Suprapubic pain, which is pain felt above the pubic bone in the lower abdomen, is a common symptom of bladder infections, including UTIs. This finding is highly suggestive of a UTI in this client.
D. Temperature of 38.2 C (100.7 F): Although fever can be a symptom of a UTI, it is not always present and can be caused by other infections or conditions. Therefore, a single elevated temperature, without other supporting symptoms, is not conclusive for a UTI diagnosis.
E. Constant urge to urinate (dysuria): Dysuria, or a frequent and urgent need to urinate, is another common symptom of UTIs. This finding, along with cloudy urine and suprapubic pain, further strengthens the suspicion of a UTI in this client.
