Nursing Elites

1. When should the nurse conduct an Allen’s test?

• A. When obtaining pulmonary artery pressures
• B. To assess for the presence of a deep vein thrombus in the leg
• C. Just before arterial blood gases are drawn peripherally
• D. Prior to attempting a cardiac output calculation

Correct answer: C

Rationale: The correct time to conduct an Allen’s test is just before arterial blood gases are drawn peripherally. This test is performed to assess the adequacy of collateral circulation in the hand before obtaining arterial blood gases. Choice A is incorrect because an Allen’s test is not specifically done when obtaining pulmonary artery pressures. Choice B is incorrect because an Allen’s test is not used to assess deep vein thrombosis. Choice D is incorrect because an Allen’s test is not done specifically before attempting a cardiac output calculation.

2. A client is admitted to a medical unit with the diagnosis of gastritis and chronic heavy alcohol abuse. What should the nurse administer to prevent the development of Wernicke's syndrome?

• A. Lorazepam (Ativan)
• B. Famotidine (Pepcid)
• C. Thiamine (Vitamin B1)
• D. Atenolol (Tenormin)

Correct answer: C

Rationale: Thiamine supplementation is critical in preventing Wernicke's syndrome, especially in clients with chronic alcohol use. Wernicke's syndrome is a neurological disorder caused by thiamine deficiency. Lorazepam is a benzodiazepine used for anxiety and not for preventing Wernicke's syndrome. Famotidine is an H2 blocker used to reduce stomach acid production but does not prevent Wernicke's syndrome. Atenolol is a beta-blocker used for hypertension and angina, not for preventing Wernicke's syndrome.

3. When admitting a client diagnosed with active tuberculosis to isolation, which infection control measures should the nurse implement?

• A. Negative pressure environment
• B. Contact precautions
• C. Droplet precautions
• D. Protective environment

Correct answer: A

Rationale: The correct answer is A: Negative pressure environment. Tuberculosis is transmitted through airborne particles, so a negative pressure room is essential to prevent the spread of the bacteria. Choice B, contact precautions, are used for infections spread by direct or indirect contact, not for tuberculosis. Choice C, droplet precautions, are for infections transmitted through respiratory droplets, not airborne particles like tuberculosis. Choice D, protective environment, is used for protecting immunocompromised patients from outside pathogens, not for preventing the spread of tuberculosis.

4. The nurse is planning care for a client admitted with a diagnosis of pheochromocytoma. Which intervention has the highest priority for inclusion in this client’s plan of care?

• A. Record urine output every hour
• B. Monitor blood pressure frequently
• C. Evaluate neurological status
• D. Maintain seizure precautions

Correct answer: B

Rationale: Pheochromocytoma is associated with severe hypertension due to excessive catecholamine release. Monitoring blood pressure frequently is the priority intervention to assess for hypertensive crises and prevent complications like stroke, heart attack, or organ damage. While recording urine output every hour, evaluating neurological status, and maintaining seizure precautions are important aspects of care, they are not the highest priority in a client with pheochromocytoma.

5. A client with osteoporosis related to long-term corticosteroid therapy receives a prescription for calcium carbonate. Which client’s serum laboratory value requires intervention by the nurse?

• A. Total calcium 9 mg/dl (2.25 mmol/L SI)
• B. Creatinine 4 mg/dl (354 micromol/L SI)
• C. Phosphate 4 mg/dl (1.293 mmol/L SI)
• D. Fasting glucose 95 mg/dl (5.3 mmol/L SI)

Correct answer: B

Rationale: An elevated creatinine level indicates possible renal impairment, which requires intervention. High creatinine levels are associated with decreased kidney function, and in this case, it suggests potential renal issues due to long-term corticosteroid therapy. Monitoring renal function is crucial in clients with osteoporosis on corticosteroid therapy to prevent further complications. Total calcium levels within the normal range are suitable for a client with osteoporosis receiving calcium carbonate. Phosphate and fasting glucose levels do not directly indicate renal impairment in this scenario.
