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. What is the primary cause of angina?

• A. Increased oxygen demand by the heart
• B. Obstruction of the coronary arteries
• C. Lack of oxygen in the lungs
• D. Decreased blood supply to the liver

Correct answer: B

Rationale: The correct answer is B: Obstruction of the coronary arteries. Angina is primarily caused by a reduced blood flow to the heart due to blockages or narrowing in the coronary arteries. Choice A is incorrect because while increased oxygen demand can contribute to angina symptoms, it is not the primary cause. Choice C is incorrect as angina is not caused by a lack of oxygen in the lungs. Choice D is also incorrect as angina is not related to decreased blood supply to the liver.

3. Which of the following is a sign of hypoglycemia?

• A. Rapid, deep breathing
• B. Increased urination
• C. Weakness and confusion
• D. High blood pressure

Correct answer: C

Rationale: The correct answer is C: Weakness and confusion. Hypoglycemia is characterized by low blood sugar levels, leading to inadequate glucose supply to the brain, resulting in symptoms like weakness and confusion. Choices A, B, and D are incorrect. Rapid, deep breathing is not typically a sign of hypoglycemia but can be seen in other conditions like respiratory issues. Increased urination is more commonly associated with conditions like diabetes mellitus, while high blood pressure is not a typical sign of hypoglycemia.

4. What is the primary therapeutic action of tamsulosin (Flomax) in a male patient with benign prostatic hyperplasia (BPH)?

• A. Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.
• B. Reduction in prostate size and improvement in urinary symptoms.
• C. Increase in urine flow and relief of urinary obstruction.
• D. Improvement in erectile function.

Correct answer: A

Rationale: The correct answer is A: Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow. Tamsulosin, a medication commonly prescribed for BPH, works by selectively blocking alpha-1 adrenergic receptors in the prostate, causing relaxation of smooth muscles in the prostate and bladder neck. This relaxation reduces the constriction in these areas, improving urinary flow and reducing symptoms such as hesitancy, urgency, frequency, and weak stream. Choice B is incorrect because tamsulosin does not directly reduce the size of the prostate. Choice C is incorrect as tamsulosin primarily acts by relaxing muscles rather than directly increasing urine flow. Choice D is incorrect as tamsulosin is not indicated for improving erectile function.

5. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What key point should the nurse include in the patient education?

• A. Tamoxifen may increase the risk of venous thromboembolism.
• B. Tamoxifen may cause hot flashes and other menopausal symptoms.
• C. Tamoxifen may cause weight gain and fluid retention.
• D. Tamoxifen may decrease the risk of osteoporosis.

Correct answer: A

Rationale: The correct answer is A: "Tamoxifen may increase the risk of venous thromboembolism." It is crucial for patients to be aware of the signs and symptoms of blood clots while taking tamoxifen. Choice B is incorrect because hot flashes and menopausal symptoms are common side effects of tamoxifen, but they are not the key point to emphasize. Choice C is incorrect as weight gain and fluid retention are potential side effects of tamoxifen but not the key point for patient education. Choice D is incorrect as tamoxifen does not decrease the risk of osteoporosis; in fact, it may increase the risk of bone loss.
