Nursing Elites

1. Seizures are diagnosed by which of the following?

• A. Electroencephalogram (EEG) and ECG
• B. Seizure symptoms and complete blood count (CBC)
• C. Seizure symptoms and electrocardiogram (ECG)
• D. Seizure symptoms and EEG

Correct answer: D

Rationale: Seizures are most accurately diagnosed by EEG, which measures brain activity. Choice A is incorrect as ECG (electrocardiogram) measures heart activity, not brain activity. Choice B is incorrect as CBC (complete blood count) is a blood test and not used to diagnose seizures. Choice C is incorrect as an ECG (electrocardiogram) also measures heart activity, not brain activity, and is not the primary diagnostic tool for seizures.

2. A patient is being treated with raloxifene (Evista) for osteoporosis. What should the nurse teach the patient about this medication?

• A. It is used as a selective estrogen receptor modulator to prevent bone loss.
• B. It works by decreasing bone formation and increasing bone resorption.
• C. It should be taken with food to reduce gastrointestinal side effects.
• D. It may cause weight gain and fluid retention.

Correct answer: C

Rationale: The correct answer is C. Raloxifene is a selective estrogen receptor modulator (SERM) used to prevent bone loss. It should be taken with food to reduce gastrointestinal side effects, not on an empty stomach. Choices A and B are incorrect because raloxifene is indeed a SERM that prevents bone loss, but it does not directly work by increasing bone formation or decreasing bone resorption. Choice D is incorrect as weight gain and fluid retention are not common side effects of raloxifene.

3. Which of the following women is at highest risk for the development of endometrial cancer?

• A. A 50-year-old postmenopausal woman with a history of high-risk human papillomavirus
• B. A 45-year-old woman who is obese and has a menstrual pattern consisting of periods of amenorrhea and infrequent periods
• C. A 40-year-old woman who is overweight and has hypertension
• D. A 55-year-old woman who smokes

Correct answer: B

Rationale: The correct answer is a 45-year-old woman who is obese and has a menstrual pattern consisting of periods of amenorrhea and infrequent periods. Obesity and prolonged exposure to estrogen unopposed by progesterone due to infrequent ovulation are significant risk factors for endometrial cancer. Choices A, C, and D do not directly correlate with the increased risk of endometrial cancer. Postmenopausal status alone (Choice A), overweight with hypertension (Choice C), and smoking (Choice D) are not the primary risk factors for endometrial cancer.

4. After ingestion of cysts, how long does it take for the symptoms of giardiasis to develop?

• A. 12 to 24 hours
• B. 3 to 5 days
• C. 1 to 2 weeks
• D. 2 to 3 months

Correct answer: B

Rationale: Giardiasis symptoms typically develop 3 to 5 days after ingestion of the cysts. This timeframe aligns with the incubation period of the Giardia parasite. Choice A (12 to 24 hours) is too short for giardiasis to manifest. Choice C (1 to 2 weeks) and choice D (2 to 3 months) represent durations that are not consistent with the usual onset of symptoms in giardiasis.

5. Which of the following women are at highest risk for the development of endometrial cancer?

• A. A 50-year-old postmenopausal woman with a history of high-risk human papillomavirus
• B. A 45-year-old woman who is obese and has menstrual irregularities with periods of amenorrhea and infrequent periods.
• C. A 40-year-old woman who is overweight and has hypertension.
• D. A 55-year-old woman who smokes.

Correct answer: B

Rationale: The correct answer is B. Obesity and irregular menstrual cycles, including periods of amenorrhea and infrequent periods, are significant risk factors for the development of endometrial cancer. Choice A is less likely as postmenopausal status reduces the risk. Choice C is not directly associated with a high risk of endometrial cancer. Choice D, smoking, is more strongly linked to other types of cancers like lung cancer rather than endometrial cancer.
