1. When treating a patient for a fungal infection with IV amphotericin B, what should the nurse consistently monitor the patient's levels of to prevent drug discomfort?
- A. sodium
- B. hemoglobin
- C. calcium
- D. leukocytes
Correct answer: C
Rationale: When a patient is being treated with IV amphotericin B for a fungal infection, it is crucial to monitor the patient's calcium levels consistently. IV amphotericin B can cause hypokalemia, hypomagnesemia, and most notably, hypocalcemia. Monitoring calcium levels helps prevent drug-related discomfort and adverse effects. Sodium (Choice A), hemoglobin (Choice B), and leukocytes (Choice D) are not the primary parameters to monitor specifically for drug discomfort related to amphotericin B. Therefore, they are incorrect choices.
2. A nurse practitioner is assessing a 7-year-old boy who has been brought to the clinic by his mother, who is concerned about her son's increasingly frequent, severe headaches. Which of the nurse's questions is least likely to yield data that will confirm or rule out migraines as the cause of his problem?
- A. Does your son have a family history of migraines?
- B. When your son has a headache, does he ever have nausea and vomiting as well?
- C. Does your son have any food allergies that have been identified?
- D. Is your son generally pain-free during the intervals between headaches?
Correct answer: C
Rationale: The correct answer is C. In assessing a child for migraines, asking about food allergies is least likely to yield data that will confirm or rule out migraines as the cause of his headaches. Food allergies are unrelated to the typical symptoms and triggers of migraines, such as family history, associated symptoms like nausea and vomiting, and pain-free intervals between headaches. Therefore, in this scenario, focusing on food allergies is less relevant for identifying migraines as the cause of the boy's headaches.
3. 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.
4. A female patient is concerned about the side effects of hormone replacement therapy (HRT). What common side effect should the nurse explain?
- A. Weight gain
- B. Hair loss
- C. Increased libido
- D. Decreased energy levels
Correct answer: A
Rationale: The correct answer is A: Weight gain. Weight gain is a common side effect of hormone replacement therapy (HRT) due to hormonal changes. Patients should be informed about this possibility as part of their treatment plan. Hair loss (Choice B) is not a common side effect of HRT. Increased libido (Choice C) and decreased energy levels (Choice D) are not typically associated with HRT side effects. Therefore, the nurse should focus on discussing weight gain with the patient.
5. A client with a history of rheumatic fever presents with signs of heart failure. What is the likely underlying cause?
- A. Infective endocarditis
- B. Coronary artery disease
- C. Mitral valve stenosis
- D. Aortic regurgitation
Correct answer: C
Rationale: The correct answer is C: Mitral valve stenosis. Rheumatic fever can lead to scarring and thickening of the heart valves, often affecting the mitral valve. This stenosis can impede blood flow from the left atrium to the left ventricle, eventually causing heart failure. Choice A, infective endocarditis, is an infection of the endocardium, the inner lining of the heart chambers and valves, and is not directly related to rheumatic fever. Choice B, coronary artery disease, involves the obstruction of coronary arteries supplying the heart muscle with blood, leading to ischemia and not typically associated with rheumatic fever. Choice D, aortic regurgitation, is the backflow of blood from the aorta to the left ventricle and is not a common consequence of rheumatic fever.
