Nokea
________ is not normally found in urine, and its presence may indicate a problem with the kidneys.
- A. Albumin
- B. Bilirubin
- C. Ammonium
- D. Urea
Correct Answer: A
Rationale: The correct answer is A: Albumin. Albumin is a protein normally found in blood but not in urine. Its presence in urine, known as proteinuria, may indicate a problem with the kidneys such as kidney damage or dysfunction in filtering blood. Bilirubin (B) is a product of red blood cell breakdown and its presence in urine indicates liver or bile duct issues. Ammonium (C) is a normal byproduct of protein metabolism and is excreted in urine. Urea (D) is a waste product of protein metabolism and is normally found in urine.

Corticosteroids are absolutely contraindicated in which of the following types * of tuberculosis?
- A. Miliary
- B. Meningeal
- C. Intestinal
- D. Renal
Correct Answer: B
Rationale: The correct answer is B: Meningeal tuberculosis.

A nurse is preparing a patient diagnosed with benign
- A. When about 80% of the nephrons are no longer prostatic hypertrophy (BPH) for a lower urinary tract functioning cystoscopic examination. The nurse informs the patient that the most common temporary complication
Correct Answer: A
Rationale: Rationale:
1. BPH can cause urinary symptoms.
2. Cystoscopy is a common diagnostic test.
3. Temporary complications include UTI or urinary retention.
4. BPH affects a significant number of nephrons.
5. Choice A aligns with BPH pathophysiology and common complications.
Summary:
- Choice A is correct due to BPH affecting nephrons and causing urinary symptoms leading to temporary complications like UTI. Other choices lack relevance to BPH or its complications.
Which of the following fungicidal drug that acts by inhibiting fungal squalene epoxidase enzyme and is the drug of choice for onychomycosis of the toe nails in 56 year old woman with diabetes?
- A. Griseofulvin
- B. Terbinafine
- C. Itraconazole
- D. Amphotericin B
Correct Answer: B
Rationale: Step 1: Terbinafine is a fungicidal drug that inhibits fungal squalene epoxidase enzyme, disrupting fungal cell membrane synthesis.
Step 2: Onychomycosis of toenails is a common fungal infection that terbinafine is specifically effective against.
Step 3: The patient being a 56-year-old woman with diabetes may require a drug with good efficacy and safety profile, making terbinafine an appropriate choice.
Step 4: Griseofulvin (A) works by disrupting microtubule function, not inhibiting squalene epoxidase. Itraconazole (C) is an azole antifungal that inhibits ergosterol synthesis, not squalene epoxidase. Amphotericin B (D) is a polyene antifungal used for systemic mycoses, not onychomycosis.
A 23 year old pregnant woman has UTI and presents to the ER with fever, * frequency and urgency. Which of the following antibiotics can cause potential harm to her fetus?
- A. Nitrrfurantoin
- B. Amoxicillin
- C. Gentamycin
- D. Cephalexin
Correct Answer: A
Rationale: The correct answer is A: Nitrofurantoin. Nitrofurantoin is contraindicated in the third trimester of pregnancy due to potential risk of hemolytic anemia in the fetus. It can also cross the placenta and reach the fetal bloodstream. Amoxicillin (B) and Cephalexin (D) are safe for use in pregnancy. Gentamycin (C) is generally not recommended during pregnancy due to potential risk of ototoxicity and nephrotoxicity but is not specifically harmful to the fetus.
A patient has been experiencing vaginal bleeding and cramping, which the nurse suspects could be an early sign of a miscarriage. Which of the following should the nurse assess for during this examination?
- A. Hyperthyroidism.
- B. High blood pressure.
- C. Weight loss and fatigue.
- D. Changes in breast size or tenderness.
Correct Answer: C
Rationale: The correct answer is C: Weight loss and fatigue. In the context of vaginal bleeding and cramping, weight loss and fatigue are concerning signs that may indicate a potential miscarriage. Weight loss could be due to decreased appetite or nutritional deficiencies associated with the stress of a miscarriage. Fatigue may result from hormonal changes and emotional distress. Assessing for weight loss and fatigue helps the nurse monitor the patient's overall well-being and provide appropriate support.
Choice A (Hyperthyroidism) is incorrect as it is not directly related to the symptoms of vaginal bleeding and cramping suggestive of a possible miscarriage.
Choice B (High blood pressure) is also incorrect as it is not typically associated with early signs of a miscarriage.
Choice D (Changes in breast size or tenderness) is incorrect as these symptoms are more commonly related to pregnancy rather than miscarriage.
