Which statement is true regarding venous thromboembolisambir b(.VcoTm/Ete)s ta nd pulmonary embolus (PE)?
- A. PE should be suspected in any patient who has unexpla ined cardiorespiratory complaints and risk factors for VTE.
- B. Bradycardia and hyperventilation are classic symptom s of PE.
- C. Dyspnea, chest pain, and hemoptysis occur in nearly a ll patients with PE.
- D. Most critically ill patients are at low risk for VTE and PE and do not require prophylaxis.
Correct Answer: A
Rationale: The correct answer is A because PE should be suspected in patients with unexplained cardiorespiratory complaints and risk factors for VTE. This is important because PE can present with nonspecific symptoms, making it crucial to consider it in the differential diagnosis.
Explanation:
1. PE can present with various symptoms, including dyspnea, chest pain, and hemoptysis, but these are not present in all patients.
2. Bradycardia and hyperventilation are not classic symptoms of PE, as it can present with tachycardia and other respiratory findings.
3. Critically ill patients are actually at higher risk for VTE and PE, so prophylaxis is typically recommended.
In summary, choice A is correct because it emphasizes the importance of considering PE in patients with cardiorespiratory complaints and risk factors for VTE, while the other choices contain inaccuracies or incomplete information.

The nurse is preparing for insertion of a pulmonary artery acbairtbh.ceotme/rte (sPt AC). During insertion of the catheter, what are the priority nursing actions? (Select all that apply.)
- A. Allay the patient’s anxiety by providing information ab out the procedure.
- B. Ensure that a sterile field is maintained during the inse rtion procedure.
- C. Inflate the balloon during the procedure when indicated by the physician.
- D. Monitor the patient’s cardiac rhythm throughout the en tire procedure.
Correct Answer: B
Rationale: The correct answer is B: Ensure that a sterile field is maintained during the insertion procedure. This is the priority nursing action because maintaining a sterile field is crucial to prevent infection during the invasive procedure. The nurse must follow strict aseptic technique to reduce the risk of introducing bacteria into the patient's bloodstream. All other choices are incorrect: A: Addressing the patient's anxiety is important but not the priority during the insertion procedure. C: Inflating the balloon is a specific action that should be performed by the physician, not the nurse. D: While monitoring the patient's cardiac rhythm is important, ensuring the sterile field takes precedence to prevent complications.
What is the treatment for an acute exacerbation of asthma?
- A. Corticosteroids and theophylline by mouth
- B. Inhaled bronchodilators and intravenous corticosteroids
- C. Prone positioning or continuous lateral rotation
- D. Sedation and inhaled bronchodilators
Correct Answer: B
Rationale: The correct answer is B: Inhaled bronchodilators and intravenous corticosteroids. Bronchodilators help to quickly open up the airways during an asthma exacerbation, providing immediate relief. Intravenous corticosteroids help reduce airway inflammation and prevent further worsening of symptoms. Corticosteroids by mouth (Choice A) are not as effective as intravenous administration during an acute exacerbation. Prone positioning or continuous lateral rotation (Choice C) is not a recommended treatment for asthma exacerbation. Sedation and inhaled bronchodilators (Choice D) are not appropriate as sedation can depress respiratory function and worsen the condition.
The patient is complaining of severe flank pain when he tries to urinate. His urinalysis shows sediment and crystals along with a few bacteria. Using this information along with the clinical picture, the nurse realizes that the patient’s condition is
- A. prerenal.
- B. postrenal.
- C. intrarenal.
- D. not renal related.
Correct Answer: C
Rationale: The correct answer is C: intrarenal. The presence of sediment, crystals, and bacteria in the urinalysis indicates an issue originating within the kidney itself. This suggests a problem like a urinary tract infection or kidney stone causing the severe flank pain. Prerenal and postrenal conditions usually involve issues outside the kidney such as dehydration or urinary tract obstruction, which are not supported by the urinalysis findings. Choice D, not renal related, is incorrect as the symptoms and urinalysis results clearly point towards a renal issue.
The nurse is assessing the patient’s pain using the Critical Care Pain Observation Tool (CPOT). Which of the following assessments would indicate the greatest likelihood of pain and need for nursing intervention?
- A. Absence of vocal sounds
- B. Fighting the ventilator
- C. Moving legs in bed
- D. Relaxed muscles in upper extremities
Correct Answer: B
Rationale: The correct answer is B: Fighting the ventilator. This behavior indicates the patient is experiencing discomfort and struggling against the ventilator, suggesting a high likelihood of pain. The CPOT assesses pain through behaviors like grimacing, vocalization, and muscle tension, which are all present when a patient is fighting the ventilator. Absence of vocal sounds (Choice A) does not necessarily indicate pain as some patients may be silent even when in pain. Moving legs in bed (Choice C) could be due to restlessness rather than pain. Relaxed muscles in upper extremities (Choice D) do not reflect pain as the CPOT focuses on behaviors indicating discomfort.
Which of the following patients is at the greatest risk of developing acute kidney injury? A patient who
- A. has been on aminoglycosides for the past 6 days
- B. has a history of controlled hypertension with a blood pressure of 138/88 mm Hg
- C. was discharged 2 weeks earlier after aminoglycoside therapy of 2 weeks
- D. has a history of fluid overload as a result of heart failure
Correct Answer: D
Rationale: The correct answer is D because a patient with a history of fluid overload due to heart failure is at the greatest risk of developing acute kidney injury. Heart failure can lead to decreased kidney perfusion causing acute kidney injury. In this scenario, the patient's fluid overload exacerbates the situation, further compromising kidney function.
Choice A is incorrect as aminoglycosides can cause kidney injury but the duration of 6 days is less concerning compared to chronic fluid overload from heart failure in choice D. Choice B is incorrect because controlled hypertension does not directly increase the risk of acute kidney injury. Choice C is incorrect as the patient being discharged 2 weeks earlier after aminoglycoside therapy does not necessarily indicate a higher risk compared to chronic fluid overload.
