Question 1 of 5
In a patient with sodium imbalances, the primary clinical manifestations are related to alterations in what body system?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
T-cell antigen receptors are distinguished from antibodies by which of the following
Correct Answer: B
Rationale: The correct answer is B. T-cell receptors must interact with antigens uniquely presented by other cells but not with free antigen. This is because T-cell receptors recognize antigens that are processed and presented on the surface of other cells via major histocompatibility complex (MHC) molecules. T-cell receptors specifically bind to the antigen-MHC complex, allowing T-cells to respond to specific foreign antigens. A: T-cell receptors are not distinguished from antibodies by glycosylation. Both T-cell receptors and antibodies can be glycosylated, so this does not differentiate them. C: T-cell receptors do not bind various cytokines. Cytokine receptors are separate entities that mediate cellular responses to cytokines. D: T-cell receptors do not bind complement to lyse cells. Complement activation is a separate immune response mechanism not involving T-cell receptors.
Question 3 of 5
Individuals unable to make the J protein found in certain immunoglobulins would be expected to have frequent infections of the
Correct Answer: A
Rationale: The correct answer is A: intestinal tract. The J protein is crucial for the proper functioning of immunoglobulins in the mucosal immune system, which plays a major role in defending against pathogens in the intestinal tract. Without the J protein, individuals would have impaired immune responses in the gut, leading to frequent infections in the intestinal tract. Choices B, C, and D are incorrect because the J protein deficiency specifically affects the mucosal immune system in the intestinal tract, not the blood, liver, or pancreas.
Question 4 of 5
The industrial nurse examines an employee who complains of right shoulder pain on abduction. He points with one finger to the exact location of the pain and mentions that he won a racquetball tournament yesterday. The nurse suspects the employee is suffering from which problem?
Correct Answer: B
Rationale: The correct answer is B: Bursitis. The employee's complaint of shoulder pain on abduction, localized pain with a specific trigger (racquetball tournament), and no mention of trauma or instability suggest an inflammatory condition like bursitis. The other choices are incorrect because a rotator cuff tear typically presents with weakness, dislocation with a history of trauma and visible deformity, and subluxation with recurrent episodes of partial dislocation.
Question 5 of 5
The nurse is performing morning care for a patient who sustained a fractured pelvis and bilateral femur fractures yesterday in a motorcycle collision. The patient complains of shortness of breath. Assessment reveals audible wheezes and oxygen saturation of 76%. What action should the nurse take first?
Correct Answer: D
Rationale: Step 1: The patient complains of shortness of breath and has audible wheezes, indicating potential respiratory distress. Step 2: Oxygen saturation of 76% is critically low and requires immediate intervention. Step 3: Raising the patient to a high Fowler position helps improve lung expansion and oxygenation. Step 4: This action takes priority to improve the patient's breathing and oxygen saturation levels. Summary: A is incorrect as establishing an IV line is not the immediate priority. B is incorrect as informing the charge nurse delays direct patient care. C is incorrect as addressing the family is secondary to addressing the patient's urgent needs.
