1. A patient is being treated for a severe fungal infection with amphotericin B. What is the expected length of treatment for this patient?
- A. 1 to 2 weeks
- B. 3 to 6 weeks
- C. 4 to 12 weeks
- D. 15 to 18 weeks
Correct answer: C
Rationale: The correct answer is C: '4 to 12 weeks.' Amphotericin B treatment duration for severe fungal infections typically ranges from 4 to 12 weeks. This extended period is necessary to ensure complete eradication of the fungal infection and prevent relapse. Choices A, B, and D provide durations that are either too short or too long for treating severe fungal infections effectively, making them incorrect.
2. In addition to matching ABO antigens, a blood transfusion must also be matched for:
- A. HLA type
- B. Rh antigen
- C. Immunoglobulins
- D. Platelet compatibility
Correct answer: B
Rationale: The correct answer is B: Rh antigen. In addition to ABO antigens, Rh antigen must also be matched for a blood transfusion. Rh antigen compatibility is crucial to prevent adverse reactions. Choice A, HLA type, is not directly related to blood transfusions but plays a role in organ transplantation. Choice C, Immunoglobulins, are not typically matched for blood transfusions. Choice D, Platelet compatibility, while important in specific cases, is not a standard requirement for all blood transfusions.
3. A client presents to the emergency department with lower right quadrant abdominal pain, fever, nausea, and occasional diarrhea. After palpating the abdomen, the client displays tenderness. What would the nurse anticipate the client to be experiencing?
- A. Pseudomembranous colitis
- B. Peptic ulcer disease
- C. Appendicitis
- D. Esophageal cancer
Correct answer: C
Rationale: The correct answer is C: Appendicitis. The symptoms described - lower right quadrant abdominal pain, fever, nausea, diarrhea, and tenderness upon palpation - are classic signs of appendicitis. Appendicitis is an inflammatory condition of the appendix that often presents with these symptoms and requires immediate medical attention. Choice A, Pseudomembranous colitis, typically presents with watery diarrhea and is associated with antibiotic use. Choice B, Peptic ulcer disease, commonly presents with epigastric pain related to meals and can be accompanied by nausea or vomiting, but it does not typically cause right lower quadrant pain. Choice D, Esophageal cancer, usually presents with symptoms related to swallowing difficulties, weight loss, and sometimes chest pain, but it is not associated with the symptoms described in the scenario.
4. A patient develops itching and burning of the vaginal vault while taking an anti-infective to treat strep throat. What fungal agent has most likely caused the burning and itching?
- A. Cryptococcus neoformans
- B. Candida albicans
- C. Aspergillus
- D. Dermatophytes
Correct answer: B
Rationale: The correct answer is B: Candida albicans. Candida albicans is a common fungal agent responsible for causing vaginal yeast infections characterized by itching and burning. It is known to overgrow in the vagina, especially when the normal vaginal flora is disrupted, such as during antibiotic use. Cryptococcus neoformans is more associated with causing meningitis in immunocompromised individuals, not vaginal symptoms. Aspergillus is more commonly associated with lung infections and allergic reactions, not vaginal infections. Dermatophytes typically cause skin infections like ringworm, not vaginal symptoms.
5. What is the main function of the mitochondria in a cell?
- A. To produce energy in the form of ATP
- B. To synthesize proteins
- C. To store genetic information
- D. To regulate cell growth
Correct answer: A
Rationale: The correct answer is A: To produce energy in the form of ATP. Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. This energy is essential for various cellular activities. Choice B is incorrect because protein synthesis primarily occurs in the ribosomes. Choice C is incorrect as the genetic information is stored in the cell's nucleus. Choice D is incorrect as the regulation of cell growth involves various other organelles and processes within the cell.
