Question 1 of 5
When preparing a site for venipunctures with alcohol, how long must the area be cleaned?
Correct Answer: D
Rationale: The correct answer is D: 60 seconds. This is because the area must be cleaned for at least 60 seconds to effectively disinfect the skin and reduce the risk of infection during venipuncture. Cleaning for shorter durations (5, 10, or 30 seconds) may not be sufficient to achieve proper disinfection. Thoroughly cleaning the area for a full minute ensures that the alcohol has enough time to kill bacteria and pathogens on the skin, making it safer for the venipuncture procedure. Shorter cleaning times may leave pathogens behind, increasing the risk of contamination and infection.
Question 2 of 5
Which of the ff does the examiner note when auscultating the lungs of a client with pleural effusion?
Correct Answer: D
Rationale: The correct answer is D because pleural effusion is the accumulation of fluid in the pleural space. When auscultating the lungs of a client with pleural effusion, the examiner would note decreased or absent breath sounds over the area where the fluid has accumulated. This is due to the fluid blocking the transmission of sound through the lungs. Pronounced breath sounds (choice A) would not be present due to the fluid obstructing the normal sound transmission. Expiratory wheezes (choice B) are associated with airway obstruction, not fluid accumulation. Friction rub (choice C) is a dry, grating sound heard with inflammation of the pleura, not specifically related to pleural effusion.
Question 3 of 5
The activation of B cells in humoral immunity is assisted by which of the following?
Correct Answer: C
Rationale: The correct answer is C: Helper T cells. Helper T cells play a crucial role in activating B cells by releasing cytokines that stimulate B cell proliferation and differentiation. They also help in the production of antibodies. Cytotoxic T cells (A) are involved in cell-mediated immunity, not humoral immunity. Suppressor T cells (B) regulate the immune response and do not directly assist in B cell activation. Neutrophils (D) are phagocytic cells involved in innate immunity, not in activating B cells in humoral immunity.
Question 4 of 5
As the nurse cares for a patient with angioedema, differs from urticaria in that angioedema is characterized by which of the following?
Correct Answer: C
Rationale: Step-by-step rationale for choice C: Angioedema differs from urticaria as it involves deeper swelling in the dermis and subcutaneous tissue, leading to a more profound and firm texture. This contrasts with urticaria, which presents as superficial, raised wheals on the skin. Therefore, option C is correct. Summary of other choices: A: Angioedema is not typically associated with intense itching, so it is not more pruritic than urticaria. B: Angioedema does not have small, fluid-filled vesicles like in allergic contact dermatitis. D: Angioedema tends to last longer than urticaria, making this statement incorrect.
Question 5 of 5
The nurse is caring for a patient with HIV who has diarrhea. Which of the following would be most therapeutic to teach the patient to avoid in the diet to reduce diarrhea?
Correct Answer: C
Rationale: The correct answer is C: Raw fruits and vegetables. Patients with HIV and diarrhea should avoid raw fruits and vegetables due to their high fiber content, which can exacerbate diarrhea symptoms. Fiber can increase bowel movements and worsen diarrhea. Therefore, avoiding raw fruits and vegetables can help reduce diarrhea. Choice A (Potassium-rich food) is not the best answer because potassium-rich foods are important for patients with HIV to maintain electrolyte balance. Choice B (Liquid nutritional supplements) can actually be beneficial in providing essential nutrients to patients with HIV. Choice D (Frozen products) is not directly related to diarrhea management in patients with HIV.
