What type of dressing will the nurse most likely use for the patient in Question 14?

Correct Answer: B

Rationale: In this scenario, the nurse would most likely use an absorptive dressing for the patient in Question 14. Absorptive dressings are designed to manage moderate to heavily exuding wounds by absorbing and retaining wound exudate. These dressings help maintain a moist wound environment conducive to healing while protecting the surrounding skin. Option A, a dry, sterile dressing, would not be ideal for a moderately exuding wound as it may lead to the dressing adhering to the wound bed, causing trauma upon removal. Option C, negative pressure wound therapy, is typically used for wounds with large amounts of exudate or in specific cases where indicated, not for moderate exudate levels. Option D, Telfa dressing with antibiotic ointment, may be used for wounds that require a non-adherent layer, but the focus in this case is on managing exudate effectively. Understanding the appropriate dressing types for various wound presentations is crucial in nursing practice to promote optimal wound healing and prevent complications. Nurses must be knowledgeable about the properties and indications of different dressings to provide effective wound care.

Correct Answer: B

Rationale: In this scenario, option B, "These cells will form new blood cells for the recipient," is the correct answer. Hematopoietic stem cells are responsible for the continuous production of blood cells in the body. When a donor provides these stem cells to a recipient in need, they can replenish the recipient's blood cell supply. This process is crucial for patients undergoing treatments like bone marrow transplants. Option A, "They must come from an embryo or umbilical cord," is incorrect because hematopoietic stem cells can also be obtained from adult donors, not just embryos or umbilical cords. It is essential for nurses to provide accurate information to potential donors to dispel any misconceptions they may have about the sources of these stem cells. Option C, "Taking these cells will cause the donor to become anemic," is incorrect. Donating hematopoietic stem cells does not lead to anemia in the donor. It is crucial for healthcare professionals to educate donors about the potential risks and side effects associated with stem cell donation, which typically do not include anemia. Option D, "These cells must be removed with a bone marrow aspiration," is incorrect because hematopoietic stem cells can be obtained through various methods, not just bone marrow aspiration. Nurses need to be knowledgeable about the different techniques used to collect stem cells to provide comprehensive information to donors and recipients. Educationally, understanding the role of hematopoietic stem cells in blood cell production and transplantation is vital for healthcare providers working in fields like oncology, hematology, and transplant medicine. Providing accurate information to potential donors helps ensure informed decision-making and promotes successful outcomes for both donors and recipients.

Correct Answer: A

Rationale: Immunoglobulin E (IgE) plays a crucial role in the immune system's response to parasitic infections. IgE is specifically designed to combat parasitic invaders by initiating an allergic response, which includes triggering the release of histamine to expel parasites. This response helps to protect the body from potential harm caused by parasitic organisms. Option B, "Responsible for allergic reactions," is incorrect because while IgE does trigger allergic reactions as part of its defense mechanism against parasites, its primary function is in combating parasitic infections. Option C, "Present on the lymphocyte surface," is incorrect as IgE is not typically found on lymphocytes. Instead, it is produced by plasma cells, a type of B lymphocyte, in response to specific antigens. Option D, "Protects body surfaces and mucous membranes," is incorrect as IgE is not primarily involved in protecting body surfaces and mucous membranes. Its main role lies in combating parasitic infections through allergic responses. In an educational context, understanding the functions of different immunoglobulins, such as IgE, is crucial for healthcare professionals in diagnosing and treating various immune-related conditions. Knowing the specific roles of each immunoglobulin can guide appropriate therapeutic interventions and improve patient outcomes.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) He has multiple chemical sensitivities. The nurse suspects this because the patient experiences symptoms like headache, sore throat, shortness of breath, and nausea when exposed to certain chemicals present in his girlfriend's perfume and the paint in her apartment. Multiple chemical sensitivities refer to individuals having exaggerated reactions to various environmental chemicals, which aligns with the patient's symptoms in this case. Option A) He has posttraumatic stress disorder does not align with the patient's symptoms and experiences related to exposure to specific chemicals, making it an incorrect choice. Option C) He needs to wear a mask when he paints is a partial measure and does not address the broader issue of multiple chemical sensitivities. Option D) He is looking for an excuse to break up with his girlfriend is an inappropriate and dismissive response to the patient's concerns. Educationally, this question highlights the importance of recognizing and understanding multiple chemical sensitivities, a condition that can significantly impact an individual's quality of life. It emphasizes the need for healthcare providers to listen to patients' symptoms and experiences to provide accurate assessments and appropriate care. Understanding such conditions is crucial in pharmacology to ensure safe and effective medication management for individuals with unique sensitivities.

Correct Answer: D

Rationale: The correct answer is D) All of the above. Methicillin-resistant Staphylococcus aureus (MRSA), Carbapenem-resistant Enterobacteriaceae (CRE), and Vancomycin-resistant Enterococcus (VRE) are the three antibiotic-resistant bacteria of most current concern in North America. MRSA is a common cause of skin infections and can lead to severe complications. CRE is a group of bacteria that are resistant to multiple antibiotics, posing a serious threat in healthcare settings. VRE is a significant concern as it can cause infections in the bloodstream, urinary tract, and wounds. The incorrect options can be explained as follows: - Option A (MRSA) is a correct antibiotic-resistant bacteria, so it is not the only correct answer. - Option B (CRE) is also a correct antibiotic-resistant bacteria, so it is not the only correct answer. - Option C (VRE) is another correct antibiotic-resistant bacteria, so it is not the only correct answer. Understanding antibiotic-resistant bacteria is crucial in pharmacology as it impacts treatment decisions, infection control practices, and public health efforts. Knowing the most concerning bacteria helps healthcare providers tailor treatment strategies and preventive measures to combat these infections effectively.
