Nursing Elites

1. A patient presents with a chronic cough, night sweats, and weight loss. A chest X-ray reveals upper lobe cavitary lesions. Which of the following is the most likely diagnosis?

• A. Tuberculosis
• B. Pneumonia
• C. Lung cancer
• D. Sarcoidosis

Correct answer: A

Rationale: The correct answer is A: Tuberculosis. Cavitary lesions in the upper lobes are classic findings seen in tuberculosis. This infectious disease commonly presents with symptoms such as chronic cough, night sweats, and weight loss. Pneumonia (Choice B) typically does not present with cavitary lesions on chest X-ray. Lung cancer (Choice C) may present with similar symptoms but is less likely to cause cavitary lesions in the upper lobes. Sarcoidosis (Choice D) usually presents with bilateral hilar lymphadenopathy and non-caseating granulomas, different from the cavitary lesions described in the case.

2. Which of the following is not an autoimmune disease?

• A. Multiple sclerosis
• B. Pernicious anemia
• C. Goodpasture syndrome
• D. Transfusion reaction

Correct answer: D

Rationale: The correct answer is D, Transfusion reaction. Transfusion reaction is not an autoimmune disease because it occurs when the immune system responds to foreign blood cells, not to the body's own cells. Choices A, B, and C (Multiple sclerosis, Pernicious anemia, Goodpasture syndrome) are autoimmune diseases where the immune system mistakenly attacks the body's own tissues or organs.

3. A teacher in a preschool is diagnosed with giardiasis. Which of the following medications will be administered to treat the diarrhea and abdominal distention?

• A. Sulfasalazine (Azulfidine)
• B. Metronidazole (Flagyl)
• C. Trimethoprim–sulfamethoxazole (Bactrim)
• D. Doxycycline (Vibramycin)

Correct answer: B

Rationale: The correct answer is B. Metronidazole (Flagyl) is the drug of choice for treating giardiasis, which is a common cause of diarrhea and abdominal distention. Sulfasalazine (Choice A) is used to treat inflammatory bowel disease. Trimethoprim–sulfamethoxazole (Choice C) is commonly used for urinary tract infections and Pneumocystis jirovecii pneumonia. Doxycycline (Choice D) is commonly used to treat various bacterial infections but is not the first-line treatment for giardiasis.

4. Which of the following is a clinical manifestation in a patient with renal impairment associated with polycystic kidney disease?

• A. Suprapubic pain
• B. Periorbital edema
• C. Low serum creatinine level
• D. Palpable kidneys

Correct answer: D

Rationale: The correct answer is D: Palpable kidneys. Polycystic kidney disease often leads to the development of multiple fluid-filled cysts within the kidneys, causing them to enlarge. Enlarged kidneys can be palpated during a physical examination. Choices A, B, and C are incorrect. Suprapubic pain is not a typical clinical manifestation of polycystic kidney disease. Periorbital edema is more commonly associated with conditions like nephrotic syndrome or heart failure. Low serum creatinine level is not expected in patients with renal impairment due to polycystic kidney disease; instead, elevated serum creatinine levels are more likely.

5. What is the primary action of bisphosphonates when prescribed to a patient with osteoporosis?

• A. It inhibits bone resorption, which helps maintain bone density.
• B. It stimulates new bone formation by increasing osteoblast activity.
• C. It increases calcium absorption in the intestines, which helps build stronger bones.
• D. It decreases calcium excretion by the kidneys, helping to maintain bone density.

Correct answer: A

Rationale: The correct answer is A: "It inhibits bone resorption, which helps maintain bone density." Bisphosphonates work by inhibiting bone resorption carried out by osteoclasts, thereby preventing the breakdown of bones and helping to maintain or increase bone density in patients with osteoporosis. Choices B, C, and D are incorrect because bisphosphonates do not directly stimulate new bone formation, increase calcium absorption in the intestines, or decrease calcium excretion by the kidneys.
