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 systolic blood pressure of 145 mm Hg is classified as:

• A. Normotensive
• B. Prehypertension
• C. Stage I hypertension
• D. Stage II hypertension

Correct answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

3. 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.

4. A serum potassium level of 3.2 mEq/L (3.2 mmol/L) is reported for a patient with cirrhosis who has scheduled doses of spironolactone (Aldactone) and furosemide (Lasix) due. Which action should the nurse take?

• A. Administer both drugs.
• B. Administer the spironolactone.
• C. Withhold the spironolactone and administer the furosemide.
• D. Withhold both drugs until discussed with the healthcare provider.

Correct answer: B

Rationale: A serum potassium level of 3.2 mEq/L is low (hypokalemia), which can be concerning in a patient with cirrhosis who is already at risk for electrolyte imbalances. Spironolactone is a potassium-sparing diuretic that can help increase the patient's potassium level and correct the hypokalemia. Therefore, the appropriate action for the nurse to take in this scenario is to administer the spironolactone. Withholding the spironolactone could further lower the potassium level. Furosemide, on the other hand, is a loop diuretic that can lead to potassium loss and worsen hypokalemia; hence, it should be withheld until the nurse discusses the situation with the healthcare provider. While the healthcare provider should be informed about the low potassium value, immediate administration of spironolactone is necessary to address the hypokalemia in this patient population.

5. A 25-year-old male client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:

• A. Should be taken in the morning
• B. May increase the client's energy level
• C. Does not need to be stored in a dark container
• D. May increase the client's heart rate

Correct answer: A

Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.
