1. An IV antibiotic is prescribed for a client with a postoperative infection. The medication is to be administered in 4 divided doses. What schedule is best for administering this prescription?

A. 1000, 1600, 2200, 0400
B. Give in equally divided doses during waking hours
C. Administer with meals and a bedtime snack
D. 0800, 1200, 1600, 2000

Correct answer: D

Rationale: The best schedule for administering the IV antibiotic in 4 divided doses is 0800, 1200, 1600, and 2000. This timing allows for equal spacing between doses, ensuring consistent therapeutic levels of the medication in the client's system. Choice A provides doses too close together, increasing the risk of medication errors and potential toxicity. Choice B's suggestion of giving doses during waking hours is vague and lacks specific timing, which may result in irregular dosing intervals. Choice C, administering with meals and a bedtime snack, is unrelated to the timing of the antibiotic doses and does not optimize the drug's effectiveness.

2. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, “I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home”. What response is best for the nurse to provide?

A. Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely
B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
C. Let me contact your healthcare provider to discuss the possibility of receiving IV heparin therapy at home
D. Why are you so anxious to leave the hospital when you know you are not well enough yet?

Correct answer: A

Rationale: The correct response is A: 'Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely.' Heparin is an anticoagulant that prevents further clot formation, but it does not quickly dissolve existing clots. It is crucial for the nurse to educate the client about the purpose of heparin and the necessity for close monitoring of bleeding risks. Choice B is incorrect as it does not address the misunderstanding about heparin's mechanism of action. Choice C is incorrect as home administration of IV heparin therapy requires careful consideration and should not be suggested without a thorough assessment. Choice D is incorrect as it does not address the client's misconception about heparin's role in dissolving clots and instead focuses on the client's desire to leave the hospital.

3. A male client is returned to the surgical unit following a left nephrectomy and is medicated with morphine. His dressing has a small amount of bloody drainage, and a Jackson-Pratt bulb surgical drainage device is in place. Which intervention is most important for the nurse to include in this client's plan of care?

A. Monitor urine output hourly
B. Assess for back muscle aches
C. Record drainage from the drain
D. Obtain body weight daily

Correct answer: C

Rationale: The most important intervention for the nurse to include in the client's plan of care following a left nephrectomy with a Jackson-Pratt bulb in place is to record drainage from the drain. Monitoring the drainage is crucial as it helps assess for potential complications such as hemorrhage, infection, or other issues related to the surgical site. Assessing urine output is important post-nephrectomy but not as critical as directly monitoring the drainage. Assessing for back muscle aches may be relevant for pain management but not as crucial as monitoring the drainage. Obtaining body weight daily is not directly related to assessing the surgical drain output and is less critical in this scenario.

4. The healthcare provider believes that a client who frequently requests pain medication may have a substance abuse problem. Which intervention reflects the healthcare provider's value of client autonomy over veracity?

A. Administer the prescribed analgesic when requested
B. Refer the client to a substance abuse program
C. Collaborate with the healthcare provider to provide a placebo
D. Document the frequency of medication requests

Correct answer: A

Rationale: Administering the prescribed analgesic when requested is the most appropriate intervention that reflects the healthcare provider's value of client autonomy over veracity. This action respects the client's right to manage their pain and avoids deception. Referring the client to a substance abuse program (Choice B) assumes a diagnosis without evidence and does not respect the client's autonomy. Collaborating to provide a placebo (Choice C) would involve deception, which goes against the value of veracity. Documenting the frequency of medication requests (Choice D) is important for the client's care but does not directly address the issue of respecting client autonomy over veracity.

5. The nurse is caring for a client with a tracheostomy. Which action should the nurse perform when suctioning the tracheostomy tube?

A. Increase wall suction while removing the suction catheter
B. Instill 10 ml of sterile saline into the tracheostomy tube before applying continuous suction
C. Suction the client’s oropharynx after tracheal suctioning
D. Insert the suction catheter into the trachea, and apply intermittent suction with removal of the catheter

Correct answer: D

Rationale: When suctioning a tracheostomy tube, it is essential to insert the suction catheter into the trachea and apply intermittent suction with removal of the catheter. This technique helps prevent damage to the trachea and reduces discomfort for the client. Choice A is incorrect because increasing wall suction with the removal of the suction catheter can cause trauma to the tracheal mucosa. Choice B is incorrect because instilling saline into the tracheostomy tube before suctioning is not recommended as it can lead to complications. Choice C is incorrect as oropharyngeal suctioning should be done before tracheal suctioning to prevent the risk of aspiration.
