Nursing Elites

1. A client with a new prescription for lithium carbonate for bipolar disorder is being educated by a nurse on early indications of toxicity. The nurse should include which of the following manifestations in the teachings?

• A. Constipation
• B. Polyuria
• C. Rash
• D. Tinnitus

Correct answer: B

Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.

2. A client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?

• A. Elevated fibrinogen level
• B. Prolonged PT
• C. Elevated platelet count
• D. Depressed d-dimer level

Correct answer: B

Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.

3. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

4. What would a healthcare professional expect to observe while assessing the growth of children during their school-age years?

• A. Decreasing amounts of body fat and muscle mass
• B. Little change in body appearance from year to year
• C. Progressive height increase of 4 inches each year
• D. Yearly weight gain of about 5.5 pounds per year

Correct answer: D

Rationale: During school-age years, children typically gain about 5.5 pounds per year and increase in height by about 2 inches annually. This steady growth pattern is expected between ages 2 to 10 years. Choice A is incorrect as children at this stage are expected to gain weight and grow in height. Choice B is incorrect as there should be noticeable changes in body appearance due to growth. Choice C is incorrect as a progressive height increase of 4 inches each year is not typical during the school-age years.

5. Is it true that Hepatitis C virus (HCV) can be spread through hugging, sneezing, coughing, sharing eating utensils, and other forms of casual contact?

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: False. HCV is not spread through casual contact such as hugging, sneezing, or sharing eating utensils. The correct modes of transmission for HCV include direct contact with human blood through blood transfusions, improperly sterilized needles and syringes, needle sharing, or occasionally through sexual contact. Therefore, the statement is false, making 'False' the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the mode of transmission of HCV.
