Nursing Elites

1. Which class of drugs is the only source of a cure for septic shock?

• A. Antihypertensives
• B. Anti-infectives
• C. Antihistamines
• D. Anticholesteremics

Correct answer: B

Rationale: The correct answer is B: Anti-infectives. Anti-infective agents, such as antibiotics, are essential in treating septic shock as they can eliminate bacteria and halt the progression of the condition by stopping the production of endotoxins. Antihypertensives (Choice A) are used to lower blood pressure, antihistamines (Choice C) are used to treat allergic reactions, and anticholesteremics (Choice D) are used to lower cholesterol levels. However, none of these drug classes directly address the bacterial infection that underlies septic shock.

2. The nurse enters a client's room to administer scheduled daily medications and observes the client leaning forward and using pursed lip breathing. Which action is most important for the nurse to implement first?

• A. Evaluate the oxygen saturation.
• B. Administer a bronchodilator.
• C. Assist the client to sit upright.
• D. Encourage slow, deep breathing.

Correct answer: A

Rationale: In this scenario, the nurse should first evaluate the oxygen saturation. This action is crucial as it provides immediate information on the client's respiratory status. Assessing the oxygen saturation can help determine the adequacy of oxygenation and guide further interventions. Administering a bronchodilator (Choice B) may be necessary based on assessment findings, but it should not be the first action without knowing the oxygen saturation level. While assisting the client to sit upright (Choice C) is generally beneficial for respiratory function, in this case, assessing oxygen saturation takes precedence. Encouraging slow, deep breathing (Choice D) can be helpful, but it is secondary to evaluating the oxygen saturation in this situation.

3. A client with a history of chronic heart failure is admitted with shortness of breath. Which assessment finding is most concerning?

• A. Crackles in the lungs
• B. Shortness of breath
• C. Elevated liver enzymes
• D. Heart rate of 100 beats per minute

Correct answer: C

Rationale: Elevated liver enzymes are concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. While crackles in the lungs and shortness of breath are common in heart failure, elevated liver enzymes specifically point towards possible liver involvement due to heart failure. A heart rate of 100 beats per minute can be expected in a client with heart failure due to compensatory mechanisms, but elevated liver enzymes signal a more severe condition.

4. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

5. A client with hyperthyroidism is admitted to the postoperative unit after subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

• A. Total calcium 5.0 mg/dL.
• B. Serum sodium 140 mEq/L.
• C. Serum potassium 4.0 mEq/L.
• D. Serum glucose 90 mg/dL.

Correct answer: A

Rationale: The correct answer is A. A calcium level of 5.0 mg/dL is critically low and could indicate hypoparathyroidism, a possible complication after thyroidectomy. Low calcium levels can lead to tetany, seizures, and cardiac dysrhythmias, requiring immediate intervention. Choices B, C, and D fall within the normal range and do not require immediate intervention in this scenario.
