A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?
- A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
- B. The ventilator coordinates delivered breaths with the client's respiratory efforts
- C. The ventilator provides a supplemental breath for every third breath of the client
- D. The ventilator provides breaths during the expiratory phase of the client's respirations
Correct Answer: B
Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

When admitting a 64-year-old patient with acute pancreatitis, the healthcare provider should specifically inquire about a history of
- A. diabetes mellitus.
- B. high-protein diet.
- C. cigarette smoking.
- D. alcohol consumption.
Correct Answer: D
Rationale: In patients with acute pancreatitis, alcohol consumption is a significant risk factor and one of the most common causes in the United States. It is crucial to assess alcohol intake as it plays a key role in the development of pancreatitis. While cigarette smoking, diabetes mellitus, and high-protein diets can contribute to various health issues, they are not directly associated with the development of acute pancreatitis.
Which goal has the highest priority in the plan of care for a 26-year-old homeless patient admitted with viral hepatitis who has severe anorexia and fatigue?
- A. Increase activity level.
- B. Maintain adequate nutrition
- C. Establish a stable environment
- D. Identify sources of hepatitis exposure
Correct Answer: B
Rationale: The highest priority outcome is to maintain adequate nutrition because it is essential for hepatocyte regeneration. In viral hepatitis, the liver is affected, and proper nutrition supports the liver's function and regeneration. While increasing activity level and establishing a stable environment are important, they are not as urgent as ensuring the patient receives proper nutrition. Identifying sources of hepatitis exposure can help prevent future infections, but in the acute phase, the immediate focus should be on providing adequate nutrition to support the patient's recovery.
A man is receiving heparin subcutaneously. The patient has dementia and lives at home with a part-time caretaker. The nurse is most concerned about which side effect of heparin?
- A. Back Pain
- B. Fever and Chills
- C. Risk for Bleeding
- D. Dizziness
Correct Answer: C
Rationale: The correct answer is 'Risk for Bleeding.' A patient with dementia may have impaired judgment and may be prone to falls or injuries, increasing the risk of bleeding while on heparin therapy. Monitoring for signs of bleeding is crucial in this situation. Choice A, 'Back Pain,' is not a common side effect of heparin. Choice B, 'Fever and Chills,' is not a typical side effect of heparin but may indicate other underlying conditions. Choice D, 'Dizziness,' is not a common side effect of heparin and is not the primary concern in this scenario.
Which patient poses the least infection risk to an immunosuppressed patient who had a liver transplant?
- A. The patient with chronic pancreatitis
- B. The patient currently infected with a respiratory virus
- C. The patient with a healing leg wound
- D. The patient with a urinary tract infection
Correct Answer: C
Rationale: The patient with a healing leg wound poses the least infection risk to an immunosuppressed patient who had a liver transplant. Chronic pancreatitis can lead to complications such as infections that can pose a risk to immunosuppressed individuals. Patients infected with respiratory viruses or urinary tract infections are actively infectious, which can put immunosuppressed patients at a higher risk of acquiring infections. Therefore, the patient with a healing leg wound is the least likely to pose an immediate infection risk.
Following a diagnosis of acute glomerulonephritis (AGN) in their 6-year-old child, the parent's remark: "We just don't know how he caught the disease!"? The nurse's response is based on an understanding that:
- A. AGN is a streptococcal infection that involves the kidney tubules.
- B. The disease is easily transmissible in schools and camps.
- C. The illness is usually associated with chronic respiratory infections.
- D. It is not "caught"? but is a response to a previous B-hemolytic strep infection.
Correct Answer: D
Rationale: The correct answer is that acute glomerulonephritis (AGN) is not 'caught' but is a response to a previous B-hemolytic strep infection. AGN is generally accepted as an immune-complex disease triggered by an antecedent streptococcal infection occurring 4 to 6 weeks prior. It is considered a noninfectious renal disease. Choice A is incorrect because AGN is not a streptococcal infection that involves the kidney tubules but rather a noninfectious renal disease. Choice B is incorrect as AGN is not easily transmissible in schools and camps but is a result of a previous streptococcal infection. Choice C is incorrect as AGN is not usually associated with chronic respiratory infections, but with a previous streptococcal infection.
