Nursing Elites

1. A 43-year-old man has tested positive for systemic candidiasis, and the care team has decided on IV fluconazole as a first-line treatment. When administering this medication, the nurse should

• A. administer the drug with lactated Ringer's.
• B. infuse the drug no faster than 200 mg/h.
• C. avoid administering the drug through a peripheral IV.
• D. administer prophylactic heparin prior to the fluconazole.

Correct answer: C

Rationale: When administering IV fluconazole, the nurse should avoid administering the drug through a peripheral IV. Fluconazole is known to cause phlebitis and tissue irritation if infused through a peripheral IV line. It is recommended to administer fluconazole through a central venous catheter to reduce the risk of complications. Choices A, B, and D are incorrect as there is no specific recommendation to administer the drug with lactated Ringer's, infuse it at a particular rate, or administer prophylactic heparin prior to fluconazole in this scenario.

2. A patient's antiretroviral therapy has not been as efficacious as her care team had predicted, and maraviroc (Selzentry) has consequently been added to her drug regimen. The nurse should recognize this drug as belonging to what category of antiretroviral?

• A. Fusion protein inhibitors
• B. Protease inhibitors
• C. CCR5 antagonists
• D. Integrase strand transfer inhibitors

Correct answer: C

Rationale: Women with a history of breast cancer should avoid hormone replacement therapy due to the increased risk of cancer recurrence.

3. Which of the following is a common cause of mechanical small intestine obstruction?

• A. Infection
• B. Postoperative adhesions
• C. Tumors
• D. Foreign body

Correct answer: B

Rationale: Postoperative adhesions are a common cause of mechanical small intestine obstruction. Adhesions can form after abdominal surgery, causing bands of scar tissue that may twist or pull the intestines, leading to obstruction. This is a more common cause compared to infection, tumors, or foreign bodies. Infection may lead to inflammation but is not a typical cause of mechanical obstruction. Tumors and foreign bodies can cause blockages but are less common than postoperative adhesions.

4. An imbalance of which of the following hormones could lead to increased calcium levels in the blood?

• A. Parathyroid hormone
• B. Antidiuretic hormone
• C. Calcitonin
• D. Melatonin

Correct answer: A

Rationale: The correct answer is Parathyroid hormone (Choice A). Parathyroid hormone plays a key role in regulating calcium levels in the blood. When there is an imbalance in parathyroid hormone secretion, it can lead to increased calcium levels in the blood. Antidiuretic hormone (Choice B) is involved in regulating water balance, not calcium levels. Calcitonin (Choice C) helps lower blood calcium levels and is unlikely to cause an increase. Melatonin (Choice D) regulates sleep-wake cycles and does not have a direct effect on calcium levels in the blood.

5. 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.
