Hematologic System Questions Questions
Question 1 of 5
A nurse has educated a client on an epinephrine autoinjector. What statement by the client indicates additional instruction is needed?
Correct Answer: A
Rationale: The correct answer is A because the statement "I don’t need to go to the hospital after using it" indicates a misunderstanding of the seriousness of anaphylaxis, which requires immediate medical attention. - Choice B is correct as carrying two autoinjectors is recommended in case the first one malfunctions or a second dose is needed. - Choice C is correct as it demonstrates proper medication management by noting the expiration date. - Choice D is incorrect as injecting through clothes is acceptable in emergencies to save time. In summary, choice A is incorrect as it shows a lack of understanding of the need for further medical care after using an epinephrine autoinjector.
Question 2 of 5
The complement:
Correct Answer: C
Rationale: The correct answer is C because the complement system enhances phagocytosis by opsonization, making it easier for phagocytes to engulf and destroy pathogens. Option A is incorrect as the complement system is not part of adaptive immunity. Option B is incorrect as antibodies are part of the humoral immune response, not the complement system. Option D is incorrect as the complement system consists of proteins, not enzymes.
Question 3 of 5
The community health nurse is conducting a research study and is identifying clients in the community at risk for latex allergy. Which client population is most at risk for developing this type of allergy?
Correct Answer: C
Rationale: The correct answer is C: Children in day care centers. Children in day care centers are at higher risk for latex allergy due to frequent exposure to latex-containing products like gloves, pacifiers, and toys. The immature immune system of children increases their susceptibility to developing allergies. Hairdressers (choice A) are also at risk due to prolonged exposure to latex gloves. The homeless (choice B) and individuals living in a group home (choice D) are not specifically at higher risk compared to children in day care centers.
Question 4 of 5
Ketoconazole is prescribed for a client with a diagnosis of candidiasis. Which interventions should the nurse include when administering this medication?
Correct Answer: B
Rationale: Correct Answer: B - Monitor liver function studies. Rationale: 1. Ketoconazole is known to have hepatotoxic side effects. 2. Monitoring liver function studies is essential to detect any signs of liver damage early. 3. Regular monitoring allows for timely intervention if hepatic toxicity occurs. Other Choices: A: Restricting fluid intake is not necessary for ketoconazole administration. C: Administering ketoconazole with an antacid may reduce its absorption. D: Avoiding sun exposure is not directly related to ketoconazole administration for candidiasis.
Question 5 of 5
A 64-year-old smoker with cough, shortness of breath, facial plethora, JVD, supraclavicular node. Most likely cause?
Correct Answer: D
Rationale: The correct answer is D: Lung cancer. The symptoms described, including cough, shortness of breath, facial plethora, JVD, supraclavicular node, are classic signs of advanced lung cancer. Lung cancer commonly presents with respiratory symptoms due to the obstruction of airways and spread to nearby structures. Long-standing hypertension (A) typically presents with symptoms related to high blood pressure, not respiratory symptoms. Gastric carcinoma (B) may present with gastrointestinal symptoms rather than respiratory symptoms. Emphysema (C) is a lung condition associated with chronic obstructive pulmonary disease and smoking but does not typically present with facial plethora, JVD, or supraclavicular node enlargement.
