Nursing Elites

1. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

2. A 67-year-old male patient with acute pancreatitis has a nasogastric (NG) tube to suction and is NPO. Which information obtained by the nurse indicates that these therapies have been effective?

• A. Bowel sounds are present.
• B. Grey Turner sign resolves.
• C. Electrolyte levels are normal.
• D. Abdominal pain is decreased.

Correct answer: D

Rationale: The correct answer is 'Abdominal pain is decreased.' In a patient with acute pancreatitis, the goal of using an NG tube for suction and keeping the patient NPO is to decrease the release of pancreatic enzymes and alleviate pain. Therefore, a decrease in abdominal pain would indicate the effectiveness of these therapies. Bowel sounds being present do not necessarily indicate treatment effectiveness, as they can still be present even if the therapies are not fully effective. Normal electrolyte levels are important but do not directly reflect the efficacy of NG suction and NPO status. The resolution of Grey Turner sign, a bruising over the flanks associated with pancreatitis, is a late and non-specific finding and waiting for it to resolve is not a reliable indicator of treatment effectiveness.

3. A patient is admitted to the hospital with a diagnosis of primary hyperparathyroidism. A nurse checking the patient's lab results would expect which of the following changes in laboratory findings?

• A. Elevated serum calcium
• B. Low serum parathyroid hormone (PTH)
• C. Elevated serum vitamin D
• D. Low urine calcium

Correct answer: A

Rationale: In primary hyperparathyroidism, there is excess secretion of parathyroid hormone (PTH) leading to increased resorption of calcium from bones and decreased excretion of calcium by the kidneys. This results in elevated serum calcium levels. Elevated serum calcium is a hallmark characteristic of primary hyperparathyroidism, making it the correct answer. Low serum parathyroid hormone (PTH) (Choice B) is incorrect because primary hyperparathyroidism is associated with elevated PTH levels due to the malfunction of the parathyroid glands. Elevated serum vitamin D (Choice C) is incorrect because primary hyperparathyroidism is not typically associated with elevated vitamin D levels. Low urine calcium (Choice D) is incorrect as primary hyperparathyroidism leads to decreased calcium excretion by the kidneys, resulting in high levels of calcium in the urine.

4. Signs and symptoms of stroke may include all of the following EXCEPT:

• A. Sudden weakness or numbness of the face, arm, or leg.
• B. Sudden confusion.
• C. Sudden headache with no known cause.
• D. Hypotension.

Correct answer: D

Rationale: Hypotension is not a typical sign or symptom of an acute stroke. The correct signs and symptoms of a stroke include sudden weakness or numbness of the face, arm, or leg, sudden confusion, and a sudden headache with no known cause. Hypotension, which refers to low blood pressure, is not a common indicator of a stroke. It is important to differentiate between hypotension and hypertension in the context of stroke symptoms, as hypertension (high blood pressure) is actually a risk factor for strokes. Sudden weakness, numbness, confusion, and headache are signs associated with a stroke due to a disruption in blood flow to the brain. Hypotension, on the other hand, primarily indicates low blood pressure and is not directly linked to the typical presentation of a stroke.

5. A patient is admitted to the emergency department with an open stab wound to the left chest. What is the first action that the nurse should take?

• A. Position the patient so that the left chest is dependent
• B. Tape a nonporous dressing on three sides over the chest wound
• C. Cover the sucking chest wound firmly with an occlusive dressing
• D. Keep the head of the patient's bed at no more than 30 degrees elevation

Correct answer: B

Rationale: The correct initial action for a patient with an open stab wound to the chest is to tape a nonporous dressing on three sides over the chest wound. This dressing technique allows air to escape during expiration but prevents air from entering the pleural space during inspiration, helping to prevent tension pneumothorax. Placing the patient so that the left chest is dependent or covering the wound with an occlusive dressing can trap air in the pleural space, leading to tension pneumothorax. Keeping the head of the bed elevated at 30 to 45 degrees helps facilitate breathing and is not the first action to take when managing an open chest wound.
