Question 1 of 5
A client has been admitted to the hospital with symptoms of Guillain-Barr© syndrome. Which aspect of the client's condition would require priority monitoring?
Correct Answer: B
Rationale: In Guillain-Barr© syndrome, respiratory muscle weakness can lead to respiratory compromise, making it crucial to prioritize monitoring for signs of respiratory distress. Monitoring oxygen saturation levels is important but is secondary to assessing for respiratory compromise in this condition. Changes in consciousness and monitoring blood pressure closely are not typically the priority in Guillain-Barr© syndrome.
Question 2 of 5
A client with a pneumothorax is receiving oxygen therapy. Which assessment finding would indicate that the treatment is effective?
Correct Answer: C
Rationale: In a client with a pneumothorax receiving oxygen therapy, improved breath sounds on the affected side would indicate effective treatment. This finding suggests that the collapsed lung is re-expanding, allowing air to flow more freely in and out of the affected area. Choices A, B, and D are incorrect: Increased respiratory rate, decreased oxygen saturation levels, and increased dyspnea and chest pain are signs of ineffective treatment or worsening of the condition in a client with a pneumothorax.
Question 3 of 5
A newborn is diagnosed with congenital intrinsic factor deficiency. Which of the following types of anemia will the nurse see documented on the chart?
Correct Answer: C
Rationale: The correct answer is C, Pernicious anemia. Pernicious anemia is associated with a congenital intrinsic factor deficiency, leading to the impaired absorption of vitamin B12. Iron deficiency anemia (Choice A) is not directly related to intrinsic factor deficiency. Sideroblastic anemia (Choice B) is characterized by defective iron uptake by developing erythrocytes and is not linked to intrinsic factor deficiency. Hemolytic anemia (Choice D) involves the premature destruction of red blood cells and is not specifically associated with intrinsic factor deficiency.
Question 4 of 5
Prior to leaving on a backpacking trip to Southeast Asia, a college student has received a tetanus booster shot. This immunization confers protection by way of what immune process?
Correct Answer: D
Rationale: The correct answer is D: Active artificial immunity. A tetanus booster shot confers protection through active artificial immunity. Active immunity involves the body producing its antibodies in response to an antigen, providing long-lasting protection. In this case, the tetanus booster shot triggers the student's immune system to produce specific antibodies against tetanus toxins. Choices A, B, and C are incorrect because passive immunity does not involve the individual's immune system producing antibodies; instead, it involves the direct transfer of antibodies from another source (natural or artificial) for immediate, but temporary, protection.
Question 5 of 5
When a healthcare professional notices that a patient has type O blood, they realize that anti-_____ antibodies are present in the patient's body.
Correct Answer: C
Rationale: Individuals with type O blood have both anti-A and anti-B antibodies in their body. This is because type O blood lacks A or B antigens on the surface of red blood cells, causing the body to produce antibodies against both A and B antigens. Therefore, the correct answer is C. Choice A and B only antibodies are incorrect because type O individuals have both anti-A and anti-B antibodies. Choice D is incorrect as O represents the blood type itself, not the antibodies present in the blood.
