Nursing Elites

1. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When a medication is administered via the IV route, the absorptive process is bypassed, leading to a more rapid onset of action. This results in a faster effect of the drug. Choice A is incorrect because changing the route of administration does not necessarily lead to increased tolerance or the need for a higher dose. Choice C is incorrect as changing the route of administration does not directly affect the protein binding of a medication. Choice D is incorrect because increasing the therapeutic index would actually reduce the risk of toxicity, not increase it.

2. Which assessment data indicates the need for the nurse to include the problem 'Risk for falls' in a client’s plan of care?

• A. Recent serum hemoglobin level of 16 g/dL
• B. Opioid analgesic received one hour ago
• C. Stooped posture with an unsteady gait
• D. Expressed feelings of depression

Correct answer: B

Rationale: The correct answer is B. The administration of opioid analgesics can impair balance and increase the risk of falls, justifying the inclusion of 'Risk for falls' in the client’s care plan. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk of falls. Choice C, stooped posture with an unsteady gait, may indicate a risk for falls, but the direct influence of opioid analgesics on balance is more immediate. Choice D, expressed feelings of depression, while important, is not a direct indicator of the immediate risk for falls associated with opioid analgesic use.

3. During the digital removal of a fecal impaction, the nurse should stop the procedure and take corrective action if which client reaction is noted?

• A. Temperature increases from 98.8° to 99.0° F.
• B. Pulse rate decreases from 78 to 52 beats/min.
• C. Respiratory rate increases from 16 to 24 breaths/min.
• D. Blood pressure increases from 110/84 to 118/88 mmHg.

Correct answer: B

Rationale: During digital removal of a fecal impaction, a vagal response can occur due to stimulation of the anal sphincter. If the client experiences bradycardia (pulse rate decreases), the nurse should stop the procedure immediately and take corrective action to prevent any complications. Choices A, C, and D are incorrect because they do not indicate a vagal response, which is the expected adverse reaction during this procedure.

4. Mr. Landon is scheduled to undergo a tracheostomy. Which nursing action is essential during tracheal suctioning?

• A. Using a water-soluble lubricant.
• B. Administering 100% oxygen before and after suctioning.
• C. Ensuring that the suction catheter is open during insertion.
• D. Assisting the client to assume a semi-Fowler's position during suctioning.

Correct answer: B

Rationale: Administering 100% oxygen before and after suctioning is crucial to prevent hypoxia, which can occur during tracheal suctioning. Hypoxia can lead to serious complications, making the provision of oxygen essential in maintaining adequate oxygenation levels for the patient undergoing tracheal suctioning. Choice A is incorrect because using a water-soluble lubricant is not directly related to the essential nursing action during tracheal suctioning. Choice C is incorrect as ensuring that the suction catheter is open during insertion is a basic requirement and not the essential action for oxygenation. Choice D is incorrect because assisting the client to assume a semi-Fowler's position is beneficial for comfort and airway alignment but is not as crucial as administering oxygen to prevent hypoxia.

5. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?

• A. Troponin
• B. Myoglobin
• C. CK-MB
• D. C-reactive protein

Correct answer: A

Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.
