Which of the following drugs valuable in the treatment of edema and * metabolic alkalosis?
- A. Digoxin
- B. Spironalctone
- C. Dobutamine
- D. Acetazolamide
Correct Answer: D
Rationale: The correct answer is D: Acetazolamide. Acetazolamide is a diuretic that inhibits carbonic anhydrase enzyme, leading to increased excretion of bicarbonate ions, thus causing metabolic alkalosis correction and reducing edema. Digoxin (A) is used for heart failure, Spironolactone (B) is a potassium-sparing diuretic, and Dobutamine (C) is a beta-adrenergic agonist used for heart failure, none of which directly address metabolic alkalosis.

Where are the glomeruli and Bowman’s capsules found?
- A. Renal pelvis
- B. Ureter
- C. Renal cortex
- D. Renal column
Correct Answer: C
Rationale: The glomeruli and Bowman's capsules are found in the renal cortex. The renal cortex is the outer layer of the kidney where the initial stages of urine formation occur. Glomeruli are clusters of capillaries responsible for filtering blood, while Bowman's capsules surround the glomeruli and collect the filtrate. The renal pelvis (A) is the innermost part of the kidney where urine collects before entering the ureter (B). Renal columns (D) are extensions of the renal cortex that project into the renal medulla. Therefore, the correct answer is C as it accurately locates the structures involved in urine filtration.
Dialysis is used to treat patients with:
- A. Acute glomerulonephritis.
- B. Renal failure.
- C. Nephrolithiasis.
- D. Pyelonephritis.
Correct Answer: B
Rationale: Step-by-step rationale:
1. Renal failure is a condition where the kidneys are unable to adequately filter waste from the blood.
2. Dialysis is a treatment used to perform the functions of the kidneys in patients with renal failure.
3. Dialysis helps remove excess waste, fluids, and toxins from the blood, maintaining proper electrolyte balance.
4. Patients with acute glomerulonephritis, nephrolithiasis, and pyelonephritis may not require dialysis as their conditions do not directly affect kidney function to the extent that renal failure does.
Summary:
- A: Acute glomerulonephritis does not always lead to renal failure requiring dialysis.
- C: Nephrolithiasis is the formation of kidney stones and may not always require dialysis.
- D: Pyelonephritis is a kidney infection and may not necessarily lead to renal failure requiring dialysis.
Which antibiotic course is inappropriate for clinical scenario?
- A. Acute simple cystitis - trimethoprim for 3 days in otherwise well young women.
- B. Acute uncomplicated pyelonephritis - gentamycin + amoxicillin IV initially followed by 7 days of Augmentin orally.
- C. Pregnancy associated cystitis - nitrofurantoin 5 mg QID for 14 days.
- D. Acute simple cystitis in male patients - Augmentin or trimethoprim for 14 days.
Correct Answer: B
Rationale: The correct answer is B because the antibiotic regimen for acute uncomplicated pyelonephritis should not include gentamycin due to its potential toxicity and nephrotoxicity. The initial use of IV gentamycin is not recommended for uncomplicated pyelonephritis. The combination of gentamycin and amoxicillin is not the standard treatment for this condition. Gentamycin should be reserved for more serious infections. The choice of Augmentin for 7 days orally is also not the standard of care for pyelonephritis. The other choices (A, C, D) are appropriate antibiotic regimens for the corresponding clinical scenarios.
The first step in urine production
- A. is called reabsorption.
- B. moves water and solutes from the renal tubules into the peritubular capillaries.
- C. is called secretion.
- D. occurs as water and solutes move from the glomerulus to the glomerular capsul
Correct Answer: D
Rationale: The correct answer is D because the first step in urine production occurs as water and solutes move from the glomerulus to the glomerular capsule during the process of filtration. This initial step involves the passive movement of water and small solutes through the filtration membrane in the glomerulus. Reabsorption (choice A) occurs later in the process when useful substances are reclaimed from the filtrate. Choice B is incorrect as it describes the process of reabsorption, not the initial step. Choice C is also incorrect as secretion is the process of actively transporting substances from the blood into the renal tubules, not the first step in urine production.
A geriatric nurse is performing an assessment of body patient whose renal function is progressively declining. systems on an 85-year-old patient. The nurse should be
- A. related change affecting the renal or following situations? urinary system?
- B. When the patients creatinine level drops below 1.2
- C. Increased ability to concentrate urine
- D. Increased bladder capacity
Correct Answer: A
Rationale: The correct answer is A because as renal function declines in an elderly patient, there will be related changes affecting the urinary system. This is important for the nurse to assess to monitor the patient's renal health and intervene as necessary. Choice B is incorrect because a decrease in creatinine level is not a typical indicator of declining renal function. Choice C is incorrect because with declining renal function, the ability to concentrate urine actually decreases. Choice D is incorrect because increased bladder capacity is not a direct result of declining renal function.
