A patient with end-stage heart failure is experiencing consaibdirebr.caobmle/te dsty spnea. What is the appropriate pharmacological management of this symptom ?
- A. Administration of 6 mg of midazolam and initiation of a continuous midazolam infusion.
- B. Administration of morphine, 5 mg IV bolus, and initia tion of a continuous morphine infusion.
- C. Hourly increases of the midazolam (Versed) infusion b y 100% dose increments.
- D. Hourly increases of the morphine infusion by 100% dose increments.
Correct Answer: B
Rationale: The correct answer is B: Administration of morphine, 5 mg IV bolus, and initiation of a continuous morphine infusion. Morphine is the preferred pharmacological management for severe dyspnea in end-stage heart failure due to its potent analgesic and anxiolytic properties.
Step-by-step rationale:
1. Morphine is a potent opioid that helps relieve dyspnea by reducing anxiety, decreasing respiratory drive, and improving overall comfort.
2. The initial IV bolus of 5 mg provides rapid relief of dyspnea.
3. Initiating a continuous morphine infusion ensures sustained relief of dyspnea.
4. Midazolam (choice A) is a benzodiazepine used for sedation and anxiety, but it is not the first-line treatment for dyspnea in this scenario.
5. Increasing the midazolam (choice C) or morphine (choice D) infusions by 100% dose increments hourly is not appropriate as

The nurse is caring for a critically ill trauma patient who is expected to be hospitalized for an extended period of time. Which of the following nursing interventions would improve the patient’s well-being and reduce anxiety the most?
- A. Arrange for the patient’s dog to be brought into the unit (per protocol).
- B. Contact the pet therapy department to bring a therapy d og in to visit.
- C. Secure the harpist to come and play soothing music fora bairnb. choomu/tre set very afternoon.
- D. Wheel the patient out near the unit aquarium to observ e the tropical fish.
Correct Answer: B
Rationale: The correct answer is B because pet therapy has been shown to reduce anxiety and improve well-being in hospitalized patients. Interacting with therapy dogs can provide comfort, companionship, and a distraction from the hospital environment. Bringing in a therapy dog can help the trauma patient feel more relaxed and supported during their extended hospital stay.
Choice A may be comforting but does not address the therapeutic benefits of pet therapy. Choice C may provide soothing music, but pet therapy has been specifically proven to reduce anxiety in patients. Choice D, observing fish in an aquarium, may be calming but does not involve the interactive benefits of pet therapy.
Following insertion of a central venous catheter, the nurse obtains a stat chest x-ray film to verify proper catheter placement. The radiologist reports to the nurse: “The tip of the catheter is located in the superior vena cava.” What is the best inter pretation of these results by the nurse?
- A. The catheter is not positioned correctly and should be removed.
- B. The catheter position increases the risk of ventricular daybisrbr.hcoymth/tmesti as.
- C. The distal tip of the catheter is in the appropriate position.
- D. The physician should be called to advance the catheter into the pulmonary artery.
Correct Answer: C
Rationale: The correct answer is C: The distal tip of the catheter is in the appropriate position.
Rationale:
1. The superior vena cava is a desirable location for a central venous catheter tip placement as it is close to the heart for rapid medication delivery.
2. Catheter tip in the superior vena cava allows for proper venous return and minimizes the risk of complications.
3. The nurse does not need to remove or adjust the catheter if the tip is in the superior vena cava.
4. Advancing the catheter into the pulmonary artery (option D) would be incorrect as it can lead to serious complications.
Incorrect choices:
A: Incorrect because placement in the superior vena cava is acceptable.
B: Incorrect as placement in the superior vena cava does not increase the risk of ventricular dysrhythmias.
D: Incorrect as advancing the catheter into the pulmonary artery is unnecessary and risky.
Conditions that produce acute kidney injury by directly acting on functioning kidney tissue are classified as intrarenal. The most common intrarenal condition is
- A. prolonged ischemia.
- B. exposure to nephrotoxic substances.
- C. acute tubular necrosis (ATN).
- D. hypotension for several hours.
Correct Answer: C
Rationale: Rationale:
1. Acute tubular necrosis (ATN) is the most common intrarenal condition as it directly affects kidney tubules.
2. ATN is characterized by damage to renal tubular cells due to various factors like toxins or ischemia.
3. Prolonged ischemia (choice A) can lead to ATN but is not the most common intrarenal condition.
4. Exposure to nephrotoxic substances (choice B) can cause ATN, but ATN itself is more common.
5. Hypotension for several hours (choice D) can result in ischemia and subsequent ATN, but ATN is still the primary intrarenal condition.
The nurse is caring for a patient with acute respiratory dist ress syndrome who is hypoxemic despite mechanical ventilation. The primary care provider (PCP) orders a nontraditional ventilator mode as part of treatment. Despite sedation and aabnirba.lcgoems/tieas,t the patient remains restless and appears to be in discomfort. The nurse informs the PCP of this assessment and anticipates what order?
- A. Continuous lateral rotation therapy
- B. Guided imagery
- C. Neuromuscular blockade
- D. Prone positioning
Correct Answer: C
Rationale: The correct answer is C: Neuromuscular blockade.
1. Neuromuscular blockade helps to achieve optimal ventilator synchrony by reducing patient-ventilator asynchrony and improving oxygenation in patients with acute respiratory distress syndrome (ARDS).
2. Despite sedation, the patient's restlessness and discomfort suggest inadequate ventilator synchrony, which can be addressed by neuromuscular blockade.
3. Continuous lateral rotation therapy (A) and prone positioning (D) are interventions for improving ventilation and oxygenation in ARDS but do not directly address patient-ventilator synchrony.
4. Guided imagery (B) is a non-pharmacological technique for relaxation and pain management, which may not address the underlying issue of ventilator synchrony in this case.
Which interventions may be included during “terminal we aning”? (Select all that apply.)
- A. Complete extubation following ventilator withdrawal
- B. Discontinuation of artificial ventilation but maintenanc e of the artificial airway
- C. Discontinuation of anxiolytic and pain medications
- D. Titration of ventilator support based upon blood gas de terminations
Correct Answer: B
Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed.
Explanation:
1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely.
2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs.
3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.
