Nursing Elites

1. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

2. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

• A. Administer bicarbonate.
• B. Complete a head-to-toe assessment.
• C. Place the patient on high-flow oxygen.
• D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.

3. A patient has taken an overdose of aspirin. Which of the following should a nurse closely monitor during acute management of this patient?

• A. Onset of pulmonary edema
• B. Metabolic alkalosis
• C. Respiratory alkalosis
• D. Parkinson's disease type symptoms

Correct answer: A

Rationale: The correct answer is to monitor the onset of pulmonary edema. In cases of aspirin overdose, metabolic acidosis is a common consequence that can lead to the development of pulmonary edema. Early signs of aspirin poisoning include symptoms like tinnitus, hyperventilation, vomiting, dehydration, and fever. Late signs may manifest as drowsiness, bizarre behavior, unsteady walking, and coma. Aspirin poisoning can cause abnormal breathing that is typically rapid and deep. Pulmonary edema may occur due to increased capillary permeability in the lungs, leading to the leakage of proteins and fluid transudation in renal and pulmonary tissues. Changes in renal tubule permeability can also affect colloid osmotic pressure, potentially contributing to pulmonary edema. Monitoring pulmonary edema is crucial in managing aspirin overdose cases to prevent further complications. Choices B, C, and D are incorrect because metabolic alkalosis, respiratory alkalosis, and Parkinson's disease type symptoms are not typically associated with aspirin overdose and are not primary concerns in its acute management.

4. When reading a lab report, you notice that a patient's sample is described as having anisocytosis. Which of the following most accurately describes the patient's condition?

• A. The patient has an abnormal condition of skin cells.
• B. The patient's red blood cells vary in size.
• C. The patient has a high level of fat cells and is obese.
• D. The patient's cells are indicative of necrosis.

Correct answer: B

Rationale: Anisocytosis is a term that indicates variation in the size of red blood cells. When a patient is described as having anisocytosis, it means their red blood cells exhibit differences in size. This condition can be detected in blood samples and may indicate underlying blood disorders. The other choices are incorrect: Choice A refers to a skin cell condition, Choice C relates to obesity and fat cells, and Choice D suggests necrosis, none of which are associated with anisocytosis or red blood cell abnormalities. It is important to recognize specific terms like anisocytosis in laboratory reports to understand the potential implications for the patient's health.

5. A patient scheduled for cataract surgery asks the nurse why they developed cataracts and how to prevent it in the future. What is the nurse's best response?

• A. Age is the biggest factor contributing to cataracts.
• B. Unprotected exposure to UV lights can cause cataracts.
• C. Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.
• D. Unfortunately, there is really nothing you can do to prevent cataracts, but they are amongst the most easily treated eye conditions.

Correct answer: C

Rationale: The correct answer is C: 'Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.' This response is the best choice as it covers the most common contributing factors for cataracts and includes preventable risk factors. Choice A is incorrect because while age is a significant factor in cataract development, it is not the only one. Choice B is incorrect as UV light exposure is a risk factor for cataracts but not the most comprehensive response. Choice D is incorrect as there are preventive measures individuals can take to reduce their risk of developing cataracts, such as protecting their eyes from UV light and managing other risk factors.
