The nurse is caring for a patient who has undergone
- A. Empty the drainage bag at least every 8 hours. creation of a urinary diversion. Forty-eight hours
- B. Irrigate the catheter every 8 hours with normal saline postoperatively, the nurses assessment reveals that the stoma is a dark purplish color. What is the nurses most
Correct Answer: C
Rationale: Rationale: Choice C is correct because it presents the only complete and coherent statement. The other options are incomplete or irrelevant, providing incorrect instructions for postoperative care. Emptying a drainage bag, irrigating a catheter, or assessing stoma color are not directly related to caring for a patient after urinary diversion surgery. Therefore, choice C is the most appropriate answer based on the context of postoperative care.

Which of the following is a respiratory response to acidosis?
- A. secretion of H+
- B. increase tubule buffer activity
- C. decreased respiratory rate
- D. decreased ventilation-perfusion ratio
Correct Answer: C
Rationale: The correct answer is C: decreased respiratory rate. Acidosis is a condition where the blood pH is below the normal range, leading to increased levels of carbon dioxide. To compensate, the body increases respiratory rate to eliminate excess CO2 through the lungs. Therefore, in response to acidosis, the respiratory rate decreases.
A: Secretion of H+ is a metabolic response, not a respiratory response to acidosis.
B: Increased tubule buffer activity is a renal response, not a respiratory response to acidosis.
D: Decreased ventilation-perfusion ratio is a consequence of respiratory diseases but not a direct response to acidosis.
Cloxacillin is indicated in infections caused by the following organism(s) * a Staphylococci
- A. Streptococci
- B. Gonococci
- C. All of the above
Correct Answer: A
Rationale: Step-by-step rationale:
1. Cloxacillin is a beta-lactam antibiotic effective against Staphylococci.
2. Streptococci are not within the spectrum of activity for Cloxacillin.
3. Gonococci are also not susceptible to Cloxacillin.
4. Therefore, the correct answer is A (Streptococci), as Cloxacillin is indicated only for Staphylococcal infections.
Summary:
Choice A is correct because Cloxacillin is effective against Staphylococci. Choices B and C are incorrect because Cloxacillin is not indicated for Gonococci or all of the organisms mentioned.
Which of the following drug/(s) that is /are used to treat chronic hepatitis B? *
- A. Lamivudine
- B. Human interferon α
- C. Amantadine
- D. (
Correct Answer: A
Rationale: Step-by-step rationale for why A (Lamivudine) is correct:
1. Lamivudine is a nucleoside analog reverse transcriptase inhibitor used to treat chronic hepatitis B.
2. It inhibits the replication of the hepatitis B virus, reducing viral load and liver damage.
3. Clinical studies have shown its efficacy in improving liver function and reducing the risk of cirrhosis.
4. Lamivudine is recommended as a first-line treatment option by major medical guidelines.
Summary of why other choices are incorrect:
B. Human interferon α: While interferon therapy was previously used, it is no longer recommended as a first-line treatment due to its side effects and lower efficacy compared to newer drugs.
C. Amantadine: Amantadine is not recommended for the treatment of chronic hepatitis B as it is not effective against the hepatitis B virus.
D. (: This is not a valid drug option for treating chronic hepatitis B.
Which is the most common from of acute glomerulonephritis?
- A. Post streptococcal.
- B. IgA nephropathy
- C. Rapidly progressive glomerulonephritis
- D. Goodpasture's syndrome
Correct Answer: A
Rationale: The correct answer is A: Post streptococcal glomerulonephritis. It is the most common form of acute glomerulonephritis caused by a previous streptococcal infection. This type of glomerulonephritis typically occurs in children and young adults. The immune response to the streptococcal infection leads to the deposition of immune complexes in the glomeruli, causing inflammation and kidney damage.
Choice B (IgA nephropathy) is a chronic form of glomerulonephritis characterized by the deposition of IgA immune complexes in the glomeruli. Choice C (Rapidly progressive glomerulonephritis) is a severe form of glomerulonephritis characterized by rapid loss of kidney function. Choice D (Goodpasture's syndrome) is a rare autoimmune disease affecting the lungs and kidneys, characterized by the production of antibodies against the basement membrane of the glomeruli.
Which statement by a new nurse teaching a patient with cystitis requires intervention?
- A. You should always drink 1 to 3 liters of fluid every day.
- B. Empty your bladder regularly even if you do not feel the urge to urinate.
- C. Drinking cranberry juice daily may decrease bacteria in your bladder.
- D. It's OK to soak in the tub with bubble bath as it will keep you clean.
Correct Answer: D
Rationale: The correct answer is D because soaking in a tub with bubble bath can exacerbate cystitis symptoms due to potential irritation from the bubble bath chemicals. This can worsen the patient's condition. A, B, and C are correct statements. A promotes proper hydration, B encourages regular emptying of the bladder to prevent bacterial growth, and C suggests a potential remedy for cystitis by consuming cranberry juice.
