A nurse is gathering medical history from a client admitted for pyelonephritis. Which of the following should the nurse expect the client to report when asked about their medical history?
The client states that they consume a high calcium diet and have had high calcium in their blood.
The client reports that they had two urinary tract infections (UTI) in the past months
The client states that they remember their mother saying their grandma had this same genetic disease.
The client reports that they took a lot of ibuprofen for arthritis for many years.
The Correct Answer is B
A. The client states that they consume a high calcium diet and have had high calcium in their blood. A high calcium diet or hypercalcemia is more associated with kidney stones, not typically with pyelonephritis.
B. The client reports that they had two urinary tract infections (UTI) in the past months. Recurrent UTIs are a risk factor for pyelonephritis, as untreated or recurrent infections can ascend from the bladder to the kidneys, leading to this condition.
C. The client states that they remember their mother saying their grandma had this same genetic disease. Pyelonephritis is not typically a genetic disease but rather an infection of the kidneys, often secondary to urinary tract infections.
D. The client reports that they took a lot of ibuprofen for arthritis for many years. Long-term NSAID use can impact kidney function but does not directly cause pyelonephritis.

Correct Answer is C
Explanation
A. Encourage the client to walk on the injured ankle to promote circulation. Weight-bearing activities should be avoided initially after a Grade II sprain to prevent further injury.
B. Immerse the ankle in warm water immediately after the injury. Ice, rather than warmth, is recommended immediately following an injury to reduce swelling and inflammation.
C. Apply ice to the affected ankle for the first 24-72 hours. Applying ice for 24-72 hours helps reduce swelling and pain by causing vasoconstriction and controlling inflammation in the acute phase.
D. Perform deep tissue massage on the injured area to reduce pain. Massaging a newly sprained ankle can aggravate inflammation and cause additional tissue damage.
Correct Answer is B
Explanation
A. The glomerular filtration rate decreases because there is a reduction of blood flow to the kidneys. Reduced blood flow to the kidneys, or renal hypoperfusion, decreases the glomerular filtration rate (GFR) because less blood is being filtered through the kidneys. This can occur in conditions such as shock, severe dehydration, or heart failure, but it is not the primary mechanism in acute tubular necrosis (ATN).
B. The glomerular filtration rate decreases because there is injury to the renal tubular cells. In ATN, the injury to renal tubular cells impairs their function, leading to reduced reabsorption and filtration ability, which contributes to the decrease in GFR.
C. The glomerular filtration rate decreases because inflammatory cells invade the already damaged kidneys. While inflammation may be present, it is not the primary cause of decreased GFR in acute tubular necrosis; reduced blood flow and tubular cell injury are more direct causes.
D. The glomerular filtration rate decreases because there is obstruction leading to the filtration system backing up and eventually shutting the kidneys down. Obstruction is not typically a characteristic of acute tubular necrosis; ATN is usually caused by ischemic or toxic injury, not physical obstruction.
