Questions About the Immune System Questions
Question 1 of 5
A ferritin level test assesses:
Correct Answer: B
Rationale: The correct answer is B: A ferritin level test assesses how much iron may be stored in the body. Ferritin is a protein that stores iron, so measuring ferritin levels gives an indication of the body's iron stores. Haemoglobin levels are not directly measured by ferritin tests (A). Ferritin levels do not assess the blood's clotting ability (C) or the number of white blood cells (D). These are unrelated to iron storage.
Question 2 of 5
People with irritable bowel syndrome often suffer with:
Correct Answer: C
Rationale: The correct answer is C: Diarrhoea and constipation. Individuals with irritable bowel syndrome (IBS) can experience alternating episodes of diarrhoea and constipation. This is due to the dysfunction in the gut-brain axis, leading to abnormal contractions in the intestines. Symptoms vary among individuals and can include bloating, abdominal pain, and changes in bowel habits. Diarrhoea and constipation are common manifestations of IBS, affecting different individuals at different times. This makes option C the correct choice. Option A (Diarrhoea) and Option D (Constipation) are incorrect because IBS is characterized by both diarrhoea and constipation, not just one or the other. Option B (Urinary tract infections) is unrelated to IBS symptoms and is not a common manifestation of the condition.
Question 3 of 5
A child with hemophilia plans on participating in a bicycling club. The nurse should recommend the child
Correct Answer: B
Rationale: The correct answer is B - Wear kneepads, elbow pads, and a helmet while bicycling. This recommendation is crucial for the safety of the child with hemophilia as it helps prevent injuries and potential bleeding episodes in case of falls. Kneepads and elbow pads provide extra protection to vulnerable joints, while a helmet protects the head from trauma. This allows the child to engage in physical activities like bicycling while minimizing the risk of bleeding complications. Choice A is incorrect because swimming may also pose a risk of injury, and protective gear is still necessary. Choice C is incorrect as it limits the child's participation and does not address safety concerns. Choice D is incorrect as it unnecessarily restricts the child's social engagement and physical activity without providing an alternative solution.
Question 4 of 5
A child undergoing chemotherapy treatment has the following laboratory values: Absolute neutrophil count of 400 mm3; Hematocrit (HCT) 32%; Platelet Count 150,000 per microliter; Serum Potassium 4.5 mmol/L. The pediatric nurse correctly determines that the child is at risk for:
Correct Answer: D
Rationale: The correct answer is D: Infection. A low Absolute neutrophil count indicates neutropenia, which increases the risk of infection due to decreased ability to fight off pathogens. Hematocrit and Platelet Count are within normal range, so anemia and bleeding are not immediate concerns. Serum Potassium level is normal, ruling out cardiac arrest risk. Therefore, the child is at highest risk for infection due to neutropenia.
Question 5 of 5
The nurse is caring for a child with disseminated intravascular coagulation (DIC). Which is a priority intervention for this child?
Correct Answer: B
Rationale: The correct answer is B: Maintenance of skin integrity. In DIC, widespread clotting leads to depletion of clotting factors and platelets, causing bleeding. Maintaining skin integrity helps prevent skin breakdown and potential bleeding complications. Frequent ambulation (A) is not a priority as it may increase the risk of bleeding. Radiograph procedures (C) are not a priority in the immediate care of DIC. Monitoring fluid restriction (D) is not the priority as maintaining skin integrity takes precedence in DIC management.
