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. The nurse determines that a postoperative client's respiratory rate has increased from 18 to 24 breaths/min. Based on this assessment finding, which intervention is most important for the nurse to implement?
- A. Encourage the client to increase ambulation in the room.
- B. Offer the client a high-carbohydrate snack for energy.
- C. Force fluids to thin the client's pulmonary secretions.
- D. Determine if pain is causing the client's tachypnea.
Correct answer: D
Rationale: An increased respiratory rate can be a sign of various issues postoperatively, including pain. Assessing and managing pain is crucial as it can lead to tachypnea. Pain, anxiety, and fluid accumulation in the lungs can all contribute to an increased respiratory rate. Therefore, determining if pain is causing the tachypnea is the most important intervention to address the underlying cause. Encouraging ambulation, offering snacks, or forcing fluids are not the priority in this situation as pain assessment takes precedence in managing the increased respiratory rate.
3. A client is receiving total parenteral nutrition (TPN). Which assessment finding is most concerning to the nurse?
- A. Blood glucose level of 150 mg/dL.
- B. Blood pressure of 110/70 mm Hg.
- C. Serum albumin level of 3.5 g/dL.
- D. The client's temperature is 100.4°F (38°C).
Correct answer: D
Rationale: A temperature of 100.4°F (38°C) (D) is the most concerning finding for a client receiving total parenteral nutrition (TPN) as it may indicate an infection, which poses a significant risk. Monitoring blood glucose level (A), blood pressure (B), and serum albumin (C) are also important, but an elevated temperature suggests a potential serious complication that requires immediate attention.
4. The client is weak from inactivity due to a 2-week hospitalization. In planning care for the client, which range of motion (ROM) exercises should the nurse include?
- A. Passive ROM exercises to all joints on all extremities four times a day.
- B. Active ROM exercises to both arms and legs two or three times a day.
- C. Active ROM exercises with weights twice a day, 20 repetitions each.
- D. Passive ROM exercises to the point of resistance and slightly beyond.
Correct answer: B
Rationale: Active ROM exercises are preferred over passive ROM to restore strength. Performing them on both arms and legs two or three times a day is effective in promoting muscle strength and mobility without the need for external assistance. Choice A is incorrect as passive ROM exercises may not help in restoring strength. Choice C is not recommended as using weights may be too strenuous for a weak client. Choice D is incorrect as passive ROM exercises to the point of resistance and slightly beyond may cause discomfort or injury to the weak client.
5. When caring for an immobile client, what nursing diagnosis has the highest priority?
- A. Risk for fluid volume deficit.
- B. Impaired gas exchange.
- C. Risk for impaired skin integrity.
- D. Altered tissue perfusion.
Correct answer: B
Rationale: When caring for an immobile client, the nursing diagnosis with the highest priority is impaired gas exchange. This is because impaired gas exchange implies difficulty with breathing, which is essential for sustaining life. Adequate oxygenation is crucial for all bodily functions, and any impairment in gas exchange can lead to serious complications, making it the priority nursing diagnosis to address in an immobile client. Choices A, C, and D are important considerations as well when caring for an immobile client, but they are secondary to impaired gas exchange. Risk for fluid volume deficit may occur due to immobility, but ensuring proper gas exchange takes precedence as it directly impacts the client's immediate survival. Risk for impaired skin integrity is a concern in immobile clients but does not pose an immediate threat to life like impaired gas exchange. Altered tissue perfusion is also critical but is usually a consequence of impaired gas exchange, reinforcing the priority of addressing gas exchange first.
