The nurses admiting a school-age child in acute renal failure o reduced glomerular filtration rate. Which urine test is the most useful clinical indication of glomerular filtration rate?
Protein level
Creatinine
Osmolality
pH
The Correct Answer is B
Creatinine is a waste product generated by muscle metabolism and excreted by the kidneys. It is commonly used as a marker of renal function because it is filtered by the glomeruli and almost entirely excreted in the urine. When there is a reduction in GFR, as in acute renal failure, creatinine levels in the blood tend to rise. Elevated serum creatinine levels are indicative of impaired kidney function and a decreased GFR.
The other options are not direct indicators of GFR:
A. Protein level: While proteinuria (elevated protein levels in urine) can be a sign of kidney dysfunction, it is not a direct measurement of GFR. Proteinuria can occur for various reasons, including glomerular damage, but it doesn't provide a precise assessment of GFR.
C. Osmolality: Urine osmolality reflects the concentration of solutes in urine but is not a direct measure of GFR. It can provide information about the concentrating ability of the kidneys, but it doesn't assess the overall filtration rate.
D. pH: Urine pH is a measure of the acidity or alkalinity of urine and is not a direct indicator of GFR. It can be influenced by factors such as diet and renal tubular function but does not directly measure the filtration rate of the glomeruli.

Correct Answer is ["480"]
Explanation
To calculate the total volume the patient will receive, you can use the formula:
Total Volume = Rate x Time
In this case, the rate is 20 mL/hr, and the time is 24 hours. Now, calculate:
Total Volume = 20 mL/hr x 24 hr = 480 mL
So, the patient will receive a total of 480 mL of the 0.9% NS solution.
Correct Answer is C
Explanation
Phimosis is a condition in which the foreskin of the penis is tight or difficult to retract over the glans (head of the penis). It is normal for infants and young boys to have a non-retractable foreskin, and it usually resolves naturally as they grow. Pulling back the foreskin forcefully or attempting to clean under it in an infant can cause injury, pain, and even infection.
The correct approach is to gently clean the external genitalia with mild soap and water, but the foreskin should not be forcibly retracted in an infant. The foreskin will gradually become more retractable on its own as the child grows.
The other statements are generally appropriate:
A. "This is a normal finding as my son is uncircumcised": Phimosis is more common in uncircumcised males, and it is often a normal developmental variation in infants.
B. "This means that there is a narrowing of his torch that could lead to an infection": This statement recognizes the possibility of complications related to phimosis, such as the risk of infection, which is accurate.
D. "If this continues to be an issue, we may have him circumcised": Circumcision may be considered in cases where phimosis persists and causes problems, but it is usually not recommended during infancy unless medically necessary. This statement acknowledges a potential treatment option.
