How much blood passes through the kidneys each minute?
Correct Answer
C. 1000ml
Explanation
The correct answer is 1000ml. The kidneys receive a large amount of blood flow as they are responsible for filtering waste products and excess fluids from the bloodstream. On average, approximately 20% of the blood pumped by the heart goes to the kidneys. This amounts to around 1000ml of blood passing through the kidneys each minute.
2.
Most of the water and electrolytes are absorbed here:
Correct Answer
B. Proximal convoluted tubule
Explanation
The proximal convoluted tubule is responsible for the majority of water and electrolyte absorption in the kidney. This tubule is located immediately after Bowman's capsule and is highly specialized for reabsorption. It has a brush border lining with microvilli that increase the surface area for absorption. The cells of the proximal convoluted tubule actively transport sodium ions out of the tubule, creating an osmotic gradient that allows for the passive reabsorption of water. Additionally, various solutes such as glucose, amino acids, and ions are also reabsorbed here. Overall, the proximal convoluted tubule plays a crucial role in maintaining fluid and electrolyte balance in the body.

What would you expect if a client came in with a spinal cord injury above the 2nd to 4th sacral vertebrae?
Correct Answer
B. A loss of bladder control
Explanation
If a client came in with a spinal cord injury above the 2nd to 4th sacral vertebrae, it is expected that they would experience a loss of bladder control. This is because the sacral nerves, which control bladder function, are located in the lower part of the spinal cord. When the spinal cord is injured above this level, the signals from the brain to the bladder are disrupted, leading to a loss of control over bladder function.
4.
This is a difficulty in, or pain during, urination:
Correct Answer
D. Dysuria
Explanation
Dysuria refers to the difficulty or pain experienced during urination. It is characterized by a burning or stinging sensation while passing urine. This condition can be caused by various factors such as urinary tract infections, bladder stones, sexually transmitted infections, or inflammation of the urethra. Treatment for dysuria depends on the underlying cause and may include antibiotics, pain relievers, or lifestyle changes. Polyuria refers to excessive urination, oliguria refers to decreased urine output, and anuria refers to the absence of urine production.
5.
This is a lack of perception of bladder fullness or the loss of ability to control urinary sphincters.
Correct Answer
A. Neurogenic Bladder
Explanation
Neurogenic bladder refers to a condition where there is a lack of perception of bladder fullness or loss of control over urinary sphincters. This can occur due to damage or dysfunction in the nerves that control bladder function. It can result in urinary retention (inability to empty the bladder completely) or urinary incontinence (involuntary leakage of urine). Therefore, the given answer "Neurogenic Bladder" correctly describes the condition mentioned in the question.
6.
What is Urinary incontinence?
Correct Answer
A. Involuntary loss of urine
Explanation
Urinary incontinence refers to the involuntary loss of urine, which means the inability to control the release of urine from the bladder. This condition can occur due to various reasons such as weak bladder muscles, nerve damage, hormonal changes, or urinary tract infections. It is a common problem, especially among older adults, and can significantly impact a person's quality of life. Treatment options for urinary incontinence depend on the underlying cause and may include lifestyle changes, pelvic floor exercises, medications, or surgery.
7.
When the nurse is caring for a patient with urinary retention, she should anticipate the order for _____________.
Correct Answer
D. A urinary catheter
Explanation
When a nurse is caring for a patient with urinary retention, they should anticipate the order for a urinary catheter. This is because a urinary catheter is a medical device that is used to drain urine from the bladder when a patient is unable to do so on their own. It helps relieve the discomfort and potential complications associated with urinary retention by allowing the urine to be emptied from the bladder.
8.
What is the primary function of the kidneys?
Correct Answer
C. Maintaining the fluid and electrolyte balance
Explanation
The primary function of the kidneys is to maintain the fluid and electrolyte balance in the body. The kidneys filter waste products and excess fluid from the blood, regulate the levels of electrolytes such as sodium, potassium, and calcium, and help to maintain the pH balance of the body. They play a crucial role in regulating blood pressure and producing urine to remove waste products from the body.
9.
What is the best treatment to relieve the urge for the patient suffering from urinary incontinence?
Correct Answer
D. Perform pelvic floor exercises to strengthen the muscles
Explanation
Performing pelvic floor exercises is the best treatment to relieve the urge for a patient suffering from urinary incontinence. These exercises help strengthen the muscles that control urine flow and can improve bladder control. Drinking lots of water and cranberry juice may have other health benefits but do not directly address the urge associated with urinary incontinence. Wearing an adult diaper can provide temporary relief but does not treat the underlying condition.
10.
Which of the following is not a true, healthy urine color?
Correct Answer
C. Urine streaked with blood
Explanation
Urine streaked with blood is not a true, healthy urine color. Blood in the urine, also known as hematuria, can indicate a variety of health conditions such as urinary tract infections, kidney stones, or even more serious issues like bladder or kidney cancer. It is important to seek medical attention if blood is present in the urine to determine the underlying cause and receive appropriate treatment.
