A nurse is caring for an adolescent client who has pneumonia and a prescription for cefpodoxime 5 mg/kg PO for 5 days. The client weighs 88 lb. How many mg should the nurse administer? (Round the answer to the nearest whole number)

A. Urine culture and sensitivity
Explanation: A urine culture and sensitivity test involves growing bacteria from a urine sample in a laboratory setting. Once the bacteria have grown, they are exposed to different antibiotics to see which one is most effective in inhibiting their growth. This helps healthcare providers identify the specific strain of bacteria causing the infection and choose the most appropriate antibiotic treatment.

B. Serum creatinine level
Explanation: Serum creatinine level is a blood test used to measure kidney function. It evaluates how well the kidneys are filtering waste from the blood. While important for assessing kidney health, it does not determine the specific bacteria causing a urinary tract infection or the appropriate antibiotic treatment.

C. Urinalysis
Explanation: Urinalysis is a broad screening test that assesses various components in the urine, such as red and white blood cells, protein, glucose, and bacteria. While it can detect signs of a urinary tract infection (such as the presence of bacteria and white blood cells), it does not identify the specific bacterial strain causing the infection or provide information about antibiotic sensitivity.

D. Kidney scan
Explanation: A kidney scan, also known as a renal scan, is a medical imaging technique used to assess the structure and function of the kidneys. It can help diagnose conditions like kidney stones, urinary obstruction, or kidney infections. However, it does not determine the strain of bacteria causing a urinary tract infection or guide antibiotic treatment.

A. Increased thickness of the subcutaneous skin layer - Aging typically results in thinning of the skin and subcutaneous tissue, making older adults more vulnerable to pressure ulcers rather than having increased thickness.

B. Changes in the character and quantity of bacterial skin flora - This is a common age-related change; however, it is not directly related to the course of treatment for a sacral pressure ulcer. Proper wound care can mitigate the impact of changes in skin flora.

C. Increased time required for wound healing - Aging often leads to a decline in the body's ability to repair and regenerate tissues, which can prolong the healing process of wounds, including pressure ulcers. Older adults may experience delayed wound healing compared to younger individuals.

D. Increased elasticity of the skin - Skin elasticity decreases with age, making older adults more susceptible to skin breakdown and pressure ulcers due to reduced skin resilience and ability to redistribute pressure. Increased elasticity would not affect the course of treatment positively but rather negatively in this context.
