The nurse is caring for a postoperative patient with chroni c obstructive pulmonary disease (COPD). Which assessment would be a cue to the patient developing postoperative pneumonia?
- A. Bradycardia
- B. Change in sputum characteristics
- C. Hypoventilation and respiratory acidosis
- D. Pursed-lip breathing
Correct Answer: B
Rationale: The correct answer is B: Change in sputum characteristics. This is a cue for postoperative pneumonia in a COPD patient because it can indicate an infection in the lungs. Postoperative pneumonia is a common complication in patients with COPD due to impaired lung function and weakened immune system. Other choices are incorrect: A) Bradycardia is not a specific indicator of postoperative pneumonia. C) Hypoventilation and respiratory acidosis can be seen in patients with COPD but are not specific to postoperative pneumonia. D) Pursed-lip breathing is a coping mechanism for patients with COPD and is not directly related to postoperative pneumonia.

The nurse is caring for a patient following insertion of a left subclavian central venous catheter (CVC). Which action by the nurse best reduces th e risk of catheter-related bloodstream infection (CRBSI)?
- A. Review daily the necessity of the central venous cathet er.
- B. Cleanse the insertion site daily with isopropyl alcohol.
- C. Change the pressurized tubing system and flush bag daily.
- D. Maintain a pressure of 300 mm Hg on the flush bag.
Correct Answer: A
Rationale: The correct answer is A: Review daily the necessity of the central venous catheter. This action reduces the risk of CRBSI by promoting early removal of unnecessary catheters, which is a key strategy in preventing infections. Unnecessary catheters increase the risk of infection due to prolonged exposure to the patient's skin flora and possible contamination during insertion. Reviewing daily ensures the catheter is only kept when necessary, minimizing the duration of catheter use and reducing the chances of infection.
Summary of other choices:
B: Cleansing the insertion site daily with isopropyl alcohol is important for maintaining skin integrity but does not directly reduce the risk of CRBSI.
C: Changing the pressurized tubing system and flush bag daily is important for maintaining catheter patency but does not directly reduce the risk of CRBSI.
D: Maintaining a pressure of 300 mm Hg on the flush bag is important for proper catheter function but does not directly reduce the risk of CR
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 cares for a terminally ill patient who is experiencing pain that is continuous and severe. How should the nurse schedule the administration of opioid pain medications?
- A. Give around-the-clock routine administration of analgesics.
- B. Provide PRN doses of medication whenever the patient requests.
- C. Offer enough pain medication to keep the patient sedated.
- D. Suggest analgesic doses that provide pain control without decreasing respiratory rate.
Correct Answer: A
Rationale: The correct answer is A: Give around-the-clock routine administration of analgesics. This is the best approach for managing continuous and severe pain in a terminally ill patient. By providing scheduled doses of opioid pain medications, the nurse ensures a consistent level of pain relief, preventing peaks and troughs in pain control. This approach also helps in preventing the patient from experiencing unnecessary suffering.
Choice B (PRN doses) may lead to inadequate pain control as the patient may wait too long before requesting medication. Choice C (keeping the patient sedated) is not appropriate as the goal is pain management, not sedation. Choice D (balancing pain control and respiratory rate) is important, but the priority should be on effectively managing the pain first.
In determining the glomerular filtration rate (GFR) or creatinine clearance, a 24-hour urine is obtained. If a reliable 24-hour urine collection is not possible,
- A. it is not possible to determine the GFR.
- B. the BUN may be used to determine renal function.
- C. an elevated BUN/creatinine ratio can be used.
- D. a standardized formula may be used to calculate GFR.
Correct Answer: D
Rationale: The correct answer is D because when a reliable 24-hour urine collection is not possible, a standardized formula can be used to estimate GFR. The Cockcroft-Gault equation or the Modification of Diet in Renal Disease (MDRD) equation are commonly used formulas to estimate GFR based on serum creatinine levels, age, gender, and race. These formulas provide a reasonable estimation of kidney function in the absence of a 24-hour urine collection.
Choice A is incorrect because there are alternative methods available to estimate GFR. Choice B is incorrect because BUN alone is not sufficient to accurately determine renal function. Choice C is incorrect because an elevated BUN/creatinine ratio is not a direct measure of GFR and may be influenced by factors other than kidney function, such as hydration status or liver function.
A patient who has experienced blunt abdominal trauma during a motor vehicle collision is complaining of increasing abdominal pain. The nurse will plan to teach the patient about the purpose of:
- A. Peritoneal lavage.
- B. Abdominal ultrasonography.
- C. Nasogastric (NG) tube placement.
- D. Magnetic resonance imaging (MRI).
Correct Answer: B
Rationale: The correct answer is B: Abdominal ultrasonography. This is because ultrasonography is a non-invasive imaging technique that can quickly evaluate for internal injuries such as organ damage or bleeding in patients with blunt abdominal trauma. It is a rapid and effective diagnostic tool to assess the extent of injury and guide further management.
Peritoneal lavage (A) is an invasive procedure used in trauma settings to detect intra-abdominal bleeding but is not typically used for teaching purposes. Nasogastric tube placement (C) is used for decompression and drainage in certain conditions but is not relevant for assessing abdominal trauma. Magnetic resonance imaging (MRI) (D) is not typically used as the initial imaging modality for acute trauma due to time constraints and its limited availability in emergency settings.
