Nursing Elites

1. The nurse administers an antibiotic for a respiratory tract infection. To evaluate the medication's effectiveness, which laboratory values should the nurse monitor?

• A. Platelet count and red blood cell count.
• B. White blood cell count and sputum culture.
• C. Hemoglobin A1c and glucose tolerance test.
• D. Arterial blood gases and serum electrolytes.

Correct answer: B

Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.

2. The healthcare provider is performing a physical assessment on a client who just had an endotracheal tube inserted. Which finding would call for immediate action by the healthcare provider?

• A. Breath sounds are audible bilaterally
• B. Mist is visible in the T-piece
• C. Pulse oximetry of 88
• D. Client is unable to verbalize

Correct answer: C

Rationale: A pulse oximetry reading of 88 indicates hypoxia, which is a serious condition requiring immediate intervention. Adequate oxygenation is crucial for the client's well-being. Choices A and B are normal findings after endotracheal intubation. Hearing bilateral breath sounds and seeing mist in the T-piece indicate proper functioning of the endotracheal tube. While choice D may indicate an issue with speaking due to the endotracheal tube, it is not as critical as the hypoxia indicated by the low pulse oximetry reading.

3. An older client is admitted with fluid volume deficit and dehydration. Which assessment finding is the best indicator of hydration status?

• A. Urine specific gravity of 1.040.
• B. Systolic blood pressure decreases by 10 points when standing.
• C. The client denies feeling thirsty.
• D. Skin turgor exhibits tenting on the forearm.

Correct answer: A

Rationale: In the context of fluid volume deficit and dehydration, urine specific gravity of 1.040 is the best indicator of hydration status. High urine specific gravity indicates concentrated urine, suggesting dehydration. Choice B, systolic blood pressure decreasing when standing, is more indicative of orthostatic hypotension rather than hydration status. Choice C, denial of thirst, is a subjective finding and may not always reflect actual hydration status. Choice D, skin turgor exhibiting tenting on the forearm, is a sign of dehydration but may not be as accurate as urine specific gravity in assessing hydration status.

4. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication ____________.

• A. Can predispose to dysrhythmias
• B. May lead to oliguria
• C. May cause irritability and anxiety
• D. Sometimes alters consciousness

Correct answer: A

Rationale: The correct answer is A: Can predispose to dysrhythmias. Hypokalemia combined with digoxin increases the risk of dysrhythmias due to the potentiation of digoxin's effects on cardiac conduction. Choice B, May lead to oliguria, is incorrect because hypokalemia is not typically associated with oliguria. Choice C, May cause irritability and anxiety, is incorrect as these symptoms are more commonly associated with hypocalcemia. Choice D, Sometimes alters consciousness, is incorrect as altered consciousness is not a typical effect of hypokalemia combined with digoxin.

5. A client with Alzheimer's disease is exhibiting signs of agitation and aggression. What is the nurse's priority intervention?

• A. Reassure the client and provide emotional support.
• B. Redirect the client to a quiet activity.
• C. Administer a PRN dose of lorazepam.
• D. Apply soft restraints as needed to prevent harm.

Correct answer: B

Rationale: The correct answer is to redirect the client to a quiet activity. This intervention helps reduce agitation and aggression in clients with Alzheimer's disease by providing a distraction and promoting a calming environment. Reassuring the client and providing emotional support (Choice A) can be beneficial but is not the priority in this situation. Administering a PRN dose of lorazepam (Choice C) should not be the first intervention due to the risk of adverse effects and should only be considered if other non-pharmacological interventions are ineffective. Applying restraints (Choice D) should be avoided unless absolutely necessary for the client's safety as it can lead to further distress and is not the initial priority intervention.
