Nursing Elites

1. Which client is at risk for hypomagnesemia?

• A. Client with a history of heart disease
• B. Client taking magnesium-based antacids
• C. Client with a parathyroid disorder
• D. Client admitted with alcohol abuse

Correct answer: D

Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.

2. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

3. After a client with an Automated Internal Cardiac Defibrillator (AICD) is successfully defibrillated for Ventricular Fibrillation (VF), what should the nurse do next?

• A. Go to the client to assess for signs and symptoms of decreased cardiac output.
• B. Call the physician to inform them of the VF episode for medication adjustments.
• C. Call the 'on-call' person in the cath lab to re-charge the ICD in case of a recurrence.
• D. Document the incident on the code report form and follow up regularly.

Correct answer: A

Rationale: After a client is successfully defibrillated, the immediate priority is to assess the client for signs and symptoms of decreased cardiac output, such as altered level of consciousness, chest pain, shortness of breath, or hypotension. This assessment is crucial to determine the effectiveness of the defibrillation and the client's current hemodynamic status. Calling the physician for medication adjustments without assessing the client first could delay essential interventions. Contacting the 'on-call' person in the cath lab to re-charge the ICD is not the initial action needed after successful defibrillation. Documenting the incident is important but should not take precedence over assessing the client's immediate condition.

4. For a client with suspected appendicitis, where should the nurse expect to find abdominal tenderness?

• A. upper right
• B. upper left
• C. lower right
• D. lower left

Correct answer: C

Rationale: The correct answer is C: lower right. Abdominal tenderness in the lower-right quadrant is a classic symptom of appendicitis. This tenderness is known as McBurney's point, which is located in the lower-right quadrant of the abdomen. Choices A, B, and D are incorrect because the tenderness associated with appendicitis is typically localized to the lower-right quadrant.

5. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?

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

Correct answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.
