Nursing Elites

1. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strangely and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:

• A. Alzheimer's disease.
• B. vascular dementia.
• C. dementia with Lewy bodies.
• D. frontotemporal dementia.

Correct answer: C

Rationale: The correct answer is dementia with Lewy bodies (DLB). Hallucinations, parkinsonian symptoms (like bradykinesia and limb rigidity), and fluctuating cognition are characteristic of DLB. Alzheimer's disease (Choice A) typically presents with memory loss as a prominent feature. Vascular dementia (Choice B) is associated with a history of strokes and step-wise cognitive decline. Frontotemporal dementia (Choice D) often presents with changes in behavior and personality rather than the parkinsonian symptoms seen in this case.

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. Macular degeneration occurs as a result of:

• A. loss of lens accommodation
• B. detachment of the retina
• C. increased intraocular pressure
• D. impaired blood supply leading to cellular waste accumulation and ischemia

Correct answer: D

Rationale: Macular degeneration is a condition that affects the macula, a part of the retina responsible for central vision. It is primarily caused by impaired blood supply to the macula, leading to cellular waste accumulation and ischemia. This results in the death of photoreceptor cells and ultimately vision loss. Choices A, B, and C are incorrect because macular degeneration is not related to the loss of lens accommodation, detachment of the retina, or increased intraocular pressure. The correct answer directly addresses the underlying pathophysiology of macular degeneration.

4. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What important instruction should the nurse provide about the use of this medication?

• A. Take the medication with food to prevent nausea.
• B. Discontinue the medication if side effects occur.
• C. Take the medication at the same time each day to maintain consistent hormone levels.
• D. Avoid prolonged sun exposure while taking this medication.

Correct answer: C

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels. This is crucial for the effectiveness of medroxyprogesterone acetate in treating endometriosis. Choice A is incorrect because there is no specific instruction related to food intake. Choice B is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Choice D is unrelated to the administration of medroxyprogesterone acetate and is not a specific consideration for this medication.

5. Which of the following is a clinical manifestation of hyperthyroidism?

• A. Tachycardia
• B. Constipation
• C. Weight gain
• D. Fatigue

Correct answer: A

Rationale: The correct answer is A: Tachycardia. Tachycardia, which is an increased heart rate, is a classic clinical manifestation of hyperthyroidism. In hyperthyroidism, there is an excess production of thyroid hormones, leading to an increased metabolic rate. This increased metabolism can cause symptoms such as a rapid heart rate. Choices B, C, and D are incorrect because constipation, weight gain, and fatigue are more commonly associated with hypothyroidism, where there is a deficiency of thyroid hormones leading to a slower metabolic rate.
