A nurse is caring for a patient with impaired renal which the nurse should monitor the patient?
- A. Accumulation of wastes
- B. The nurse should facilitate collection of what
- C. Retention of potassium
- D. Depletion of calcium
Correct Answer: A
Rationale: The correct answer is A because impaired renal function can lead to the accumulation of wastes in the body, causing toxicity. Monitoring this is crucial for the patient's overall health. Choice B is incorrect as it does not directly relate to the consequences of impaired renal function. Choice C, retention of potassium, is also incorrect as it is a specific outcome of impaired renal function and not the primary focus of monitoring. Choice D, depletion of calcium, is incorrect as impaired renal function is more likely to lead to hypercalcemia rather than hypocalcemia. Therefore, the nurse should prioritize monitoring the accumulation of wastes in a patient with impaired renal function.

Glomerular filtrate is produced as a result of
- A. tubule secretion
- B. facilitated diffusion
- C. blood colloid osmotic pressure
- D. blood hydrostatic pressure
Correct Answer: D
Rationale: The correct answer is D: blood hydrostatic pressure. Glomerular filtrate is produced as a result of the pressure exerted by the blood in the glomerular capillaries forcing water and small solutes into the Bowman's capsule. This pressure, known as blood hydrostatic pressure, is the driving force for the initial filtration of blood in the kidneys.
Rationale:
1. A: Tubule secretion is the process by which substances are actively transported from the blood into the renal tubules, not the initial production of glomerular filtrate.
2. B: Facilitated diffusion is a passive transport process that requires specific carrier proteins, not a mechanism for producing glomerular filtrate.
3. C: Blood colloid osmotic pressure is the pressure exerted by proteins in the blood that tends to pull water back into the capillaries, opposing filtration, not causing the production of glomerular filtrate.
What is the upper expanded region of the ureter called?
- A. Renal pelvis
- B. Renal papilla
- C. Renal pyramids
- D. Renal cortex
Correct Answer: A
Rationale: The correct answer is A: Renal pelvis. The upper expanded region of the ureter is called the renal pelvis, which is where the major calyces converge to collect urine before it travels down the ureter. The other choices are incorrect: B) Renal papilla is the tip of the renal pyramid where urine is collected before entering the minor calyx, C) Renal pyramids are the conical structures in the renal medulla that contain the nephrons, and D) Renal cortex is the outer region of the kidney where the nephrons are located.
When the nurse is performing a genital examination on a male patient, the patient has an erection. The nurses most appropriate action or response is to:
- A. Ask the patient if he would like someone else to examine him.
- B. Continue with the examination as though nothing has happened
- C. reassure the patient that it is normal
- D. Stop the examination, leave the room while stating that the examination will resume at a later tim
Correct Answer: C
Rationale: The correct answer is C: reassure the patient that it is normal. An erection during a genital examination is a normal physiological response and not under the patient's control. By reassuring the patient, the nurse helps alleviate any potential embarrassment or anxiety. Asking for someone else (A) may further embarrass the patient. Continuing as if nothing happened (B) may ignore the patient's emotional well-being. Stopping the examination and leaving (D) without explanation can create confusion and discomfort.
A 75 year old man is suffering from benign prostatic hypertrophy and is being * treated with terazosin. Which of the following adverse reaction would be expected taking this drug?
- A. Erectile dysfunction
- B. Orthostatic hypotension
- C. GI distress
- D. Gynecomastia
Correct Answer: B
Rationale: The correct answer is B: Orthostatic hypotension. Terazosin is an alpha-1 blocker commonly used to treat BPH. It can cause vasodilation, leading to a drop in blood pressure, especially when standing up suddenly, resulting in orthostatic hypotension. This is because terazosin relaxes smooth muscle in blood vessels, causing dilation and blood pooling in the extremities. Erectile dysfunction (A) is not a common side effect of terazosin. GI distress (C) is less likely because terazosin does not directly affect the gastrointestinal system. Gynecomastia (D) is not a typical side effect of terazosin since it does not impact hormone levels significantly.
Cloxacillin is indicated in infections caused by the following organism(s):
- A. Staphylococci
- B. Streptococci
- C. Gonococci
- D. All of the above
Correct Answer: A
Rationale: Cloxacillin is a beta-lactam antibiotic effective against Staphylococci. Staphylococci commonly cause skin and soft tissue infections. Streptococci are not typically treated with cloxacillin. Gonococci are not susceptible to cloxacillin. Therefore, the correct answer is A, as it is the only organism listed that is indicated for treatment with cloxacillin.
