Nursing Elites

1. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?

• A. As a single-dose 200 mEq oral tablet
• B. As an intravenous bolus over 15 to 20 minutes
• C. In an intravenous solution at a rate of 10 mEq/hour
• D. In an intravenous solution at a rate of 45 mEq/hour

Correct answer: C

Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.

2. A client presents with a fungal urinary tract infection (UTI). Which assessments should the nurse complete? (Select all that apply.)

• A. Palpate the kidneys and bladder.
• B. Assess the medical history and current medical problems.
• C. Perform a bladder scan to assess post-void residual.
• D. Inquire about recent travel to foreign countries.

Correct answer: B

Rationale: When assessing a client with a fungal UTI, the nurse should prioritize gathering information related to the medical history and current medical problems. Clients who are severely immunocompromised or have conditions like diabetes mellitus are more susceptible to fungal UTIs. Assessing the medical history helps identify risk factors and potential causes of the infection. While physical examinations like palpating the kidneys and bladder and performing a bladder scan may be necessary, they should follow the initial assessment of medical history. Inquiring about recent travel to foreign countries is less relevant in the context of a fungal UTI, as the focus should be on immediate medical factors predisposing the client to the infection.

3. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.

4. Which of the following lab results is most indicative of dehydration?

• A. Low sodium levels.
• B. Elevated creatinine levels.
• C. Low potassium levels.
• D. High blood glucose levels.

Correct answer: B

Rationale: Elevated creatinine levels are indicative of dehydration because when the body is dehydrated, the kidneys concentrate urine to preserve fluid, leading to higher levels of creatinine. Low sodium levels (Choice A) can be seen in conditions like hyponatremia but are not specific to dehydration. Low potassium levels (Choice C) are more commonly associated with conditions like hypokalemia. High blood glucose levels (Choice D) are typically seen in diabetes and are not specific indicators of dehydration.

5. A client has just returned to the nursing unit after computerized tomography (CT) with contrast medium. Which of the following actions should the nurse plan to take as part of routine after-care for this client?

• A. Administering a laxative
• B. Encouraging fluid intake
• C. Maintaining the client on strict bed rest
• D. Holding all medications for at least 2 hours

Correct answer: B

Rationale: After CT scanning with contrast medium, the client does not require special restrictions or interventions. Encouraging fluid intake is important to help flush out the contrast dye and prevent dehydration. Administering a laxative (Choice A) is unnecessary and not indicated after CT with contrast. Maintaining the client on strict bed rest (Choice C) is not necessary unless specified by the healthcare provider. Holding all medications for at least 2 hours (Choice D) is not a standard practice after CT with contrast.
