Question 1 of 5
Raynaud's disease- information to include in teaching?
Correct Answer: B
Rationale: The correct answer is B because Raynaud's disease is characterized by reduced blood flow to extremities in response to cold or stress, leading to color changes, numbness, and tissue damage. Wearing layers of clothing helps maintain body heat and prevent cold-induced attacks, protecting against tissue damage. Walking and exercise are beneficial, but not in large intervals as it can trigger attacks. Increasing exposure to cold can worsen symptoms. Limiting fluid intake does not directly impact Raynaud's symptoms.
Question 2 of 5
Platelets are manufactured in:
Correct Answer: C
Rationale: Platelets are manufactured in the bone marrow because it is the primary site of hematopoiesis, where all blood cells, including platelets, are produced. The bone marrow contains stem cells that differentiate into various blood cell types, including platelets. The large intestine and small intestine are not involved in blood cell production. The liver plays a role in blood clotting by producing certain proteins, but it does not manufacture platelets. Therefore, the correct answer is C: The bone marrow.
Question 3 of 5
In the context of HIV prevention what does PRP stand for?
Correct Answer: A
Rationale: The correct answer is A: Pre-exposure prophylaxis (PrEP) in the context of HIV prevention involves taking antiretroviral medication before potential exposure to prevent infection. This is effective in reducing the risk of HIV transmission. B: Postexposure prophylaxis (PEP) is taken after potential exposure to prevent infection. C: Postexposure pneumonia is not a recognized term in HIV prevention. D: Pre-exposure pneumonia is not a recognized term in HIV prevention.
Question 4 of 5
The nurse is caring for a child with sickle cell disease experiencing severe chest pain, fever, a cough, and dyspnea. What is the nurse’s priority action?
Correct Answer: C
Rationale: The correct answer is C: Notify the health care practitioner because chest syndrome is suspected. Chest syndrome is a life-threatening complication in sickle cell disease characterized by acute chest pain, fever, cough, and dyspnea. The priority action is to notify the healthcare provider immediately for further evaluation and treatment. Administering oxygen (choice A) is important but not the priority in this case. Administering pain medication (choice B) can provide some relief but does not address the underlying cause. Notifying the healthcare provider for a suspected stroke (choice D) is not appropriate based on the symptoms described.
Question 5 of 5
A nurse is developing a plan of care for 5-year-old child with a diagnosis of sickle cell anemia and formulates the following nursing diagnoses. The nurse should select which nursing diagnosis as the priority?
Correct Answer: B
Rationale: The correct answer is B: Deficient Fluid Volume. For a child with sickle cell anemia, dehydration can lead to sickling of red blood cells, causing pain crises. Addressing fluid volume deficit is crucial to prevent complications. Activity Intolerance (A) may result from anemia but is secondary to fluid volume deficit. Disabled Family Coping (C) and Imbalanced Nutrition (D) are important but not as urgent as addressing fluid volume deficit to prevent acute complications.
