1. What is the primary cause of primary hypercholesteremia?

Correct answer: D

Rationale: The correct answer is 'Low-density lipoprotein (LDL) receptor mutation with defects in breakdown.' Primary hypercholesteremia is mainly caused by mutations in the LDL receptor, leading to impaired clearance of LDL cholesterol from the blood. This results in high levels of LDL cholesterol in the bloodstream. Choices A, B, and C are incorrect because they do not directly relate to the primary cause of primary hypercholesteremia.

2. A 1-year-old child will receive her scheduled MMR vaccination shortly. The nurse should teach the child's parents that she may develop what possible adverse effect related to the administration of this vaccine?

Correct answer: A

Rationale: The correct answer is A: Cough and fever. After receiving the MMR vaccine, some children may experience mild adverse effects such as a low-grade fever and a mild cough. These symptoms are normal reactions to the vaccine and indicate that the child's immune system is responding appropriately. Choices B, C, and D are incorrect because pallor and listlessness, serum sickness, nausea, and vomiting are not common adverse effects associated with the MMR vaccine in children.

3. How can a nurse determine the efficacy of a child's mebendazole treatment for roundworm after 3 weeks?

Correct answer: B

Rationale: The correct answer is B: Stool for ova and parasites. To assess the efficacy of treatment for roundworm, the nurse would examine the stool for ova (eggs) and parasites. This test helps determine if the infection has been cleared. Choices A, C, and D are incorrect because liver function tests are not commonly used to monitor roundworm treatment efficacy, and colonoscopy/sigmoidoscopy as well as rectal swab for culture are not routine diagnostic tests for assessing the effectiveness of mebendazole treatment for roundworm.

4. What is the treatment for patients with hemophilia A?

Correct answer: B

Rationale: The correct treatment for patients with hemophilia A is Factor VIII replacement. Hemophilia A is a genetic disorder where there is a deficiency in clotting factor VIII. Therefore, replacing this factor is crucial in managing and preventing bleeding episodes. Choice A, chemotherapy, is not the correct treatment for hemophilia A. Choice C, heparin administration, is not recommended as it can further increase the risk of bleeding in patients with hemophilia. Choice D, bone marrow transplant, is not a standard treatment for hemophilia A.

5. Identify which conditions are due to excessive immune response.

Correct answer: D

Rationale: The correct answer is D: Allergies and rheumatoid arthritis. Allergies are caused by an excessive immune response to harmless substances, while rheumatoid arthritis is an autoimmune disorder where the immune system attacks the body's tissues, leading to inflammation and joint damage. Choices A, B, and C are incorrect. Onychomycosis is a fungal infection of the nails, Type II diabetes is a metabolic disorder not primarily related to immune response, smallpox is a viral infection, chronic renal failure is a kidney condition, and macular degeneration is an eye disorder, none of which are directly linked to excessive immune response.
