Nursing Elites

1. In a patient with chronic kidney disease and a hemoglobin level of 9 g/dL, which of the following treatments is most appropriate?

• A. Iron supplementation
• B. Erythropoiesis-stimulating agents
• C. Blood transfusion
• D. Vitamin B12 supplementation

Correct answer: B

Rationale: In chronic kidney disease, anemia commonly occurs due to decreased erythropoietin production. Erythropoiesis-stimulating agents, such as erythropoietin or darbepoetin, are the mainstay of treatment to stimulate red blood cell production. Iron supplementation is more appropriate for iron-deficiency anemia, not the anemia of chronic kidney disease. Blood transfusion is reserved for severe cases or acute blood loss. Vitamin B12 supplementation is indicated for megaloblastic anemia caused by vitamin B12 deficiency, not specifically in chronic kidney disease-related anemia.

2. A client with a history of tuberculosis (TB) is experiencing a recurrence of symptoms. Which diagnostic test should the nurse anticipate being ordered?

• A. Sputum culture
• B. Bronchoscopy
• C. Chest x-ray
• D. CT scan of the chest

Correct answer: C

Rationale: A chest x-ray is the most appropriate diagnostic test for a client with a history of tuberculosis experiencing a recurrence of symptoms. A chest x-ray is commonly used to visualize the lungs and check for signs of active tuberculosis, such as abnormal shadows or nodules. While a sputum culture (Choice A) can confirm the presence of TB bacteria, it may not be the initial test ordered for a recurrence. Bronchoscopy (Choice B) and CT scan of the chest (Choice D) are more invasive and usually reserved for cases where the chest x-ray is inconclusive or to further assess complications, rather than as the initial diagnostic test for a recurrence of tuberculosis.

3. A 74-year-old woman states that many of her peers underwent hormone replacement therapy (HRT) in years past. The woman asks the nurse why her primary care provider has not yet proposed this treatment for her. What fact should underlie the nurse's response to the woman?

• A. The risks of stroke and breast cancer are unacceptably high in women taking HRT.
• B. HRT was found to cause mood disturbances in many women who used it long term.
• C. HRT was found to be a significant risk factor for bone fractures and osteoporosis.
• D. The risks of chronic obstructive pulmonary disease were found to be significantly higher in women using HRT.

Correct answer: A

Rationale: The correct answer is A because the main reason HRT is not recommended for all women is due to the increased risks of stroke and breast cancer associated with its use. Hormone replacement therapy (HRT) has been linked to an elevated risk of stroke and breast cancer, which outweigh its potential benefits for many individuals. Choices B, C, and D are incorrect as they do not address the primary concerns regarding HRT use. While HRT can indeed cause mood disturbances and may affect bone health, the significant risks of stroke and breast cancer are the primary reasons why healthcare providers may choose not to recommend HRT for some women.

4. A client with multiple sclerosis (MS) is frustrated by tremors associated with the disease. How should the nurse explain why these tremors occur? Due to the demyelination of neurons that occurs in MS:

• A. there is an imbalance in acetylcholine and dopamine, leading to tremors.
• B. there is a disruption in nerve impulse conduction, causing tremors.
• C. muscles are unable to receive impulses, resulting in tremors.
• D. the reflex arc is disrupted, leading to muscle tremors.

Correct answer: B

Rationale: In multiple sclerosis (MS), demyelination of neurons disrupts nerve impulse conduction. This disruption in nerve impulses can lead to tremors, explaining why the client experiences tremors in MS. Choice A is incorrect because tremors in MS are primarily due to nerve conduction issues, not an imbalance in acetylcholine and dopamine. Choice C is incorrect as it oversimplifies the process; the issue lies in nerve impulses, not the muscle's ability to receive them. Choice D is incorrect as the primary cause of tremors in MS is the disruption in nerve impulse conduction, not the reflex arc being disrupted.

5. Medroxyprogesterone acetate (Provera) is indicated for the treatment of women with

• A. uterine bleeding.
• B. cervical cancer.
• C. ovarian cancer.
• D. fibromyalgia.

Correct answer: A

Rationale: Medroxyprogesterone acetate (Provera) is commonly used to treat conditions like abnormal uterine bleeding, amenorrhea, and endometriosis. It helps regulate the menstrual cycle and reduce excessive bleeding. Therefore, the correct answer is A. Choice B, cervical cancer, is incorrect because Provera is not indicated for the treatment of cancer. Choice C, ovarian cancer, is also incorrect as Provera is not a primary treatment for ovarian cancer. Choice D, fibromyalgia, is unrelated to the use of medroxyprogesterone acetate.
