Teach the client about the blood pressure effects of the medication and relevant safety measures.
A client began taking hydrochlorothiazide 1 week ago and is reporting occasional dizziness when she stands up quickly from sitting or lying. What is the nurse's best action? Educate the client about the need for bed rest until her body adjusts to the new medication. Teach the client about the blood pressure effects of the medication and relevant safety measures. Tell the client to withhold the next scheduled dose until she can be assessed by the provider. Arrange for the client's potassium levels to be assessed as soon as possible.
Thiazide diuretics
A client has a history of frequent bladder infections. What classification of diuretic would be contraindicated for this client? Potassium-sparing diuretics Osmotic diuretics Loop diuretics Thiazide diuretics
A very large majority of filtrate is returned to circulation.
A client has been diagnosed with renal failure and is surprised to learn of the large volume of blood that is filtered by the kidneys. The client asks, "If that much blood gets filtered, why don't people produce more urine than they do?" In response, the nurse should describe what phenomenon? Electrolytes draw the water from urine back into circulation. Most of the substances that are removed from urine are recycled. Most urine is processed internally rather than excreted. A very large majority of filtrate is returned to circulation.
Intravenously
A client is admitted in acute renal failure and prescribed mannitol. The nurse prepares to administer this drug via which route? Intravenously Orally Subcutaneously Intramuscularly
Mannitol
A client is diagnosed with increased intracranial pressure. Which would the nurse expect to be ordered? Mannitol Furosemide Bumetanide Amiloride
Oral
A client is receiving hydrochlorothiazide. The nurse would expect to administer this drug by which route?
Hypokalemia
A client who has been taking hydrochlorothiazide arrives at the clinic for his 1-month follow-up appointment. The client tells the nurse that he feels weaker since he began taking the drug. What should the nurse consider as a possible cause of these symptoms? Hypokalemia Hypocalcemia Hypercalcemia Hyperkalemia
Response of pupils to light
A client with cerebral edema is prescribed mannitol. Which assessment should the nurse prioritize during the ongoing assessment? Joint pain Response of pupils to light Blood pressure every 4 hours Serum uric acid concentrations
Potassium losses are lower with spironolactone than with furosemide.
A client with hypertension has been prescribed spironolactone. The client's previous diuretic, furosemide, has been discontinued. The nurse should explain what benefit of this change? The diuretic effect is greater with spironolactone than with furosemide. Unlike furosemide, spironolactone can be taken on an outpatient basis. Sodium losses are greater with spironolactone. Potassium losses are lower with spironolactone than with furosemide.
Monitoring of serum electrolytes, creatinine, and BUN
A client with renal impairment is in need of a diuretic. Because of the renal problem, potassium-sparing diuretics are contraindicated but may be used if there is no other option. If they are used at all, what nursing intervention would be most important for this client? Monitoring of CBC and serum albumin Administration of a thiazide diuretic Monitoring of serum electrolytes, creatinine, and BUN Administration of concurrent potassium

A nurse is teaching a colleague about loop diuretics. What drugs should the nurse address? Select all that apply. Mannitol Acetazolamide Torsemide Bumetanide Ethacrynic acid
"Actually, patients with renal failure usually can't take hydrochlorothiazide."
A patient with a longstanding diagnosis of chronic renal failure has experienced a significant decline in urine output in recent days, prompting him to seek care at a local clinic. A nurse at the clinic has suggested to a colleague that the administration of a diuretic such as hydrochlorothiazide may improve the patient's urine output. How should the colleague best respond to this suggestion? "Maybe, but hydrochlorothiazide affects the bladder more than the kidneys." "That would only work if he could come in twice a day to get it intravenously." "That would probably help, but we'd have to do blood work first." "Actually, patients with renal failure usually can't take hydrochlorothiazide."
Increased blood glucose levels
A primary health care provider has prescribed a loop diuretic for hypertension in a client with diabetes mellitus. Which assessment should the nurse prioritize? Sudden increase in weight Increased blood glucose levels Sudden pain in the joints Occurrence of gout attacks
"I need to make sure I don't eat too many high potassium foods."
After teaching a patient about the action of spironolactone, the nurse determines that the teaching was successful when the patient states: "I should take the medicine around dinnertime for the best effect." "I can still use my salt substitute if I want to." "I need to make sure I don't eat too many high potassium foods." "I need to take the drug on an empty stomach."

The students are studying the male reproductive system. The instructor tells the students that in the male, the urethra leaves the urinary bladder and passes through the: prostate gland. vas deferens. renal cortex. renal calyx.
The renal pelvises drain urine into the ureters.
What best describes the structure of the kidneys? The renal arteries arise from the renal cortex. The glomerulus produces erythropoietin. The renal pelvises drain urine into the ureters. The cortical nephrons concentrate urine.
The filtration of fluid from the blood into the kidney's nephron tubule is impaired
What is the expected outcome when the glomerular membrane is damaged? The kidney's ability to regulate the concentration of urine is impaired The reabsorption of substances from the renal tubule back into the vascular system is altered The chemical reaction that results in the formation of sodium bicarbonate is impaired The filtration of fluid from the blood into the kidney's nephron tubule is impaired
Filtration
What term is used to describe the process that moves fluid and small particles out of the blood through the glomerulus and into the nephron tubule Excretion Secretion Filtration Reabsorption
Extensive kidney damage has usually occurred by the time the patient is symptomatic.
When explaining the underlying mechanisms associated with renal failure, which would be most important for the nurse to keep in mind? Renal failure typically involves some injury to the protective layers of the kidneys. Extensive kidney damage has usually occurred by the time the patient is symptomatic. Manifestations occur when a small number of nephrons become nonfunctional. Nephron damage is not associated with the development of signs and symptoms.
