Nursing Elites

1. The nurse is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?

• A. Potassium.
• B. B-type natriuretic peptide (BNP).
• C. C-reactive protein (CRP).
• D. Platelets.

Correct answer: B

Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.

2. The client is taking Antabuse and should avoid eating foods that may trigger a disulfiram reaction. The nurse should instruct the client to avoid:

• A. Peanuts, dates, raisins
• B. Figs, chocolate, eggplant
• C. Pickles, salad with vinaigrette dressing, beef
• D. Milk, cottage cheese, ice cream

Correct answer: C

Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.

3. Which of the following blood pressure parameters indicates PIH? Elevation over a baseline of:

• A. 30 mmHg systolic and/or 15 mmHg diastolic.
• B. 40 mmHg systolic and/or 20 mmHg diastolic.
• C. 10 mmHg systolic and/or 5 mmHg diastolic.
• D. 20 mmHg systolic and/or 20 mmHg diastolic.

Correct answer: A

Rationale: The correct answer is A: 30 mmHg systolic and/or 15 mmHg diastolic. These parameters indicate mild PIH (pregnancy-induced hypertension). Mild preeclampsia is characterized by an increase in systolic blood pressure greater than 30 mmHg or an increase in diastolic blood pressure greater than 15 mmHg, observed on two readings taken 6 hours apart (or reaching 140/90). Choice B (40 mmHg systolic and/or 20 mmHg diastolic) represents a more significant elevation and would indicate a more severe condition than mild PIH. Choices C (10 mmHg systolic and/or 5 mmHg diastolic) and D (20 mmHg systolic and/or 20 mmHg diastolic) do not meet the criteria for indicating PIH as they are below the accepted parameters for mild PIH.

4. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?

• A. metastatic liver cancer
• B. gram-negative septicemia
• C. pernicious anemia
• D. iron-deficiency anemia

Correct answer: C

Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice B) can lead to disseminated intravascular coagulation (DIC) causing excessive bleeding. Iron-deficiency anemia (choice D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.

5. A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:

• A. urinary excess
• B. hyperpituitarism
• C. urinary deficit
• D. hyperthyroidism

Correct answer: C

Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.
