Question 1 of 5
Teaching with an AP who is caring for active pulmonary tuberculosis, placed on airborne precautions, and is scheduled for chest x-ray- instructions?
Correct Answer: B
Rationale: Correct Answer: B Rationale: 1. Having the client wear a surgical mask helps contain respiratory droplets, reducing the risk of spreading TB. 2. Surgical masks protect others from inhaling infectious particles. 3. Airborne precautions are in place to prevent transmission through the air. 4. Wearing gloves or keeping the client in a negative pressure room does not address airborne transmission. Summary: Choice A is incorrect because the AP should not wear a gown during transport. Choice C is unnecessary as gloves do not prevent airborne transmission. Choice D is incorrect as it does not directly address containing respiratory droplets.
Question 2 of 5
The nurse is reviewing the chart of a patient who has been prescribed tacrolimus to prevent organ rejection after a transplant. What category of immunosuppressant does this drug fall into?
Correct Answer: C
Rationale: The correct answer is C: calcineurin inhibitor. Tacrolimus falls under this category as it inhibits the enzyme calcineurin, which plays a crucial role in T-cell activation. This action suppresses the immune response and prevents organ rejection. Corticosteroids (choice A) work by suppressing inflammation, antimetabolites (choice B) interfere with nucleic acid metabolism, and monoclonal antibodies (choice D) target specific immune cells or proteins, but they do not directly inhibit calcineurin like tacrolimus.
Question 3 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 4 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 5 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.
