1. 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.

2. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

3. When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?

• A. Rapid bronchospasms
• B. Inflammatory epithelial lesions
• C. Increased secretions
• D. Increased mucosal edema

Correct answer: A

Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.

4. A healthcare professional is preparing to palpate and percuss a patient's abdomen as part of the assessment process. Which of these findings would cause the healthcare professional to immediately discontinue this part of the assessment?

• A. The patient states, 'That sounds like it might hurt me.'
• B. There is a pulsating mass on the upper middle abdomen.
• C. The patient has black, tarry stools and anemia.
• D. The patient has had an endoscopic procedure two days prior.

Correct answer: B

Rationale: A pulsating mass on the upper middle abdomen is indicative of a life-threatening aortic aneurysm. Palpating or percussing such an area can potentially cause the aneurysm to rupture, leading to severe internal bleeding and endangering the patient's life. Therefore, the healthcare professional should immediately discontinue the assessment to prevent any harm.\nChoice A is incorrect because the patient expressing concerns about the procedure does not necessarily indicate a life-threatening condition. Choice C describes symptoms that should be further investigated but do not pose an immediate threat during abdominal assessment. Choice D, a prior endoscopic procedure, is not a contraindication for palpation or percussion of the abdomen unless there are specific complications or conditions related to the procedure that would require caution.

5. The healthcare professional is taking the health history of a patient being treated for sickle cell disease. After being told the patient has severe generalized pain, the healthcare professional expects to note which assessment finding?

• A. Severe and persistent diarrhea
• B. Intense pain in the toe
• C. Yellow-tinged sclera
• D. Headache

Correct answer: C

Rationale: In patients with sickle cell disease, severe generalized pain can be associated with vaso-occlusive crises, but yellow-tinged sclera is a common clinical finding related to sickle cell disease. This yellowing of the sclera, known as jaundice, occurs due to the release of bilirubin from damaged or destroyed red blood cells. Severe and persistent diarrhea is not a typical assessment finding in sickle cell disease. Intense pain in the toe may be associated with vaso-occlusive crisis but is not the expected assessment finding in this scenario. Headache is a common symptom in many conditions but is not specifically related to the assessment finding expected in a patient with sickle cell disease presenting with severe generalized pain.
