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.

A patient has had three pregnancies and two live births. The nurse would record this information as gravida _____, para _____, AB _____
- A. 2; 2; 1
- B. 3; 2; 0
- C. 3; 2; 1
- D. 3; 3; 1
Correct Answer: C
Rationale: The correct answer is C: 3; 2; 1. Gravida refers to the total number of pregnancies, including the current one. As the patient has had three pregnancies, the gravida is 3. Para indicates the number of live births, so since the patient has had two live births, the para is 2. AB represents the number of abortions or miscarriages, which is 1 in this case. Therefore, the correct way to record this patient's obstetric history is gravida 3, para 2, AB 1.
Choice A (2; 2; 1) is incorrect because the patient has had three pregnancies, not two. Choice B (3; 2; 0) is incorrect as it does not account for the abortion/miscarriage that occurred. Choice D (3; 3; 1) is also incorrect because the patient has had two live births, not three.
Intravenous furosemide is an alternative potent diuretic to Mannitol in the * treatment of the following condition:
- A. Cardiac edema
- B. Cerebral edema
- C. Cirrhotic edema
- D. Pulmonary edema
Correct Answer: B
Rationale: Rationale: Mannitol is typically used for cerebral edema due to its osmotic diuretic properties that reduce intracranial pressure. Furosemide is a loop diuretic commonly used for conditions like pulmonary edema. Therefore, intravenous furosemide is an alternative potent diuretic to Mannitol in the treatment of cerebral edema.
Summary:
A: Cardiac edema - Loop diuretics like furosemide are commonly used in cardiac edema, not Mannitol.
C: Cirrhotic edema - Loop diuretics are used in cirrhotic edema, but Mannitol is not typically indicated.
D: Pulmonary edema - Furosemide is commonly used in pulmonary edema, but Mannitol is not indicated for this condition.
Which of the following diuretics than can cause gynecomastia, hirsutism and menstrual disturbances as adverse reactions?
- A. Hydrochlorothiazide
- B. Bumetanide
- C. Acetazolamide
- D. Spironolactone
Correct Answer: D
Rationale: Step-by-step rationale:
1. Spironolactone is a potassium-sparing diuretic that acts as an aldosterone antagonist.
2. Aldosterone antagonism can lead to anti-androgenic effects, causing gynecomastia and hirsutism in males and menstrual disturbances in females.
3. Hydrochlorothiazide (A) is a thiazide diuretic known for electrolyte imbalances, not these specific side effects.
4. Bumetanide (B) is a loop diuretic that primarily affects electrolytes, not causing hormonal side effects.
5. Acetazolamide (C) is a carbonic anhydrase inhibitor, usually associated with metabolic acidosis, not hormonal disturbances.
Summary:
Spironolactone (D) is the correct answer due to its aldosterone antagonist properties causing hormonal side effects. The other choices do not have the same mechanism of action and are not associated with gynecomastia,
During an examination, the nurse notices that a male patient has a red, round, superficial ulcer with a yellowish serous discharge on his penis. On palpation, the nurse finds a nontender base that feels like a small button between the thumb and fingers. At this point the nurse suspects that this patient has:
- A. COM
- B. Genital warts.
- C. Herpes infection.
- D. Syphilitic chancr
Correct Answer: D
Rationale: The correct answer is D: Syphilitic chancre. The description of a red, round, superficial ulcer with a yellowish serous discharge on the penis, along with a nontender base that feels like a small button, is indicative of a primary syphilitic chancre. This lesion is typically painless and can be mistaken for other genital ulcers, but the specific characteristics described point towards syphilis. Genital warts (choice B) present as cauliflower-like growths, herpes infection (choice C) typically causes painful blisters, and chancroid (choice A) is characterized by soft, painful ulcers. Syphilitic chancre is the most likely diagnosis based on the presentation described.
Which statement best describes Zidovudine: *
- A. Zidovudine in combination with other antiretrovirals is an alternative initial treatment for HIV infection.
- B. Zidovudine is also used to prevent transmission of HIV from the mother to her
- C. Zidovudine is converted by cellular enzymes to an active form, zidovudine diphosphate, which prevents viral DNA from replicating.
- D. Peripheral neuropathy is a specic adverse reaction to Zidovudine
Correct Answer: C
Rationale: Rationale for Correct Answer (C):
1. Zidovudine is a nucleoside reverse transcriptase inhibitor (NRTI) used in the treatment of HIV.
2. Zidovudine is indeed converted by cellular enzymes to its active form, zidovudine diphosphate.
3. Zidovudine diphosphate inhibits the reverse transcriptase enzyme, preventing viral DNA replication in HIV-infected cells.
4. This mechanism of action is crucial in reducing viral load and slowing disease progression in HIV patients.
Summary of Incorrect Choices:
A: Incorrect. While Zidovudine is used in combination therapy for HIV, it is not typically an alternative initial treatment.
B: Incorrect. Zidovudine can be used to prevent mother-to-child transmission of HIV, but it is not its primary indication.
D: Incorrect. Peripheral neuropathy is not a specific adverse reaction to Zidovudine; rather, it is more commonly associated with
