A pregnant client requires immediate but temporary protection from chickenpox. Which type of immunization would be required?

Correct Answer: D

Rationale: The correct answer is D: Passive immunization. This involves administering pre-formed antibodies to provide immediate protection. In the case of a pregnant client needing temporary protection from chickenpox, passive immunization is necessary as it offers immediate immunity without stimulating the client's immune system. - A (Naturally acquired active immunization): This involves exposure to the pathogen and the body producing its antibodies, which takes time and is not suitable for immediate protection. - B (Artificially acquired passive immunization): This option doesn't involve providing pre-formed antibodies, which are needed for immediate protection. - C (Artificially acquired active immunization): This method requires time for the body to develop its immunity, not providing immediate protection as needed in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Fat. Excessive ingestion of fat has been linked to autoimmunity due to its potential to trigger inflammation in the body, which can disrupt the immune system's balance and lead to autoimmune responses. High-fat diets have been associated with increased production of pro-inflammatory molecules, impacting immune function negatively. Protein (choice A) is essential for immune function, vitamin A (choice B) supports immune responses, and zinc (choice D) is crucial for immune system regulation. However, excessive intake of these nutrients typically does not directly lead to autoimmunity like excessive fat consumption does.

Correct Answer: B

Rationale: The correct answer is B: Sit upright, leaning slightly forward. This position helps to minimize blood flow to the head, reducing the risk of increased bleeding. It also prevents blood from flowing down the throat, reducing the risk of aspiration. A: Lying supine with the neck extended can increase pressure on the blood vessels in the head, potentially worsening the epistaxis. C: Blowing the nose and putting lateral pressure can disrupt any clots that may have formed and increase bleeding. D: Holding the nose while bending forward at the waist can lead to blood flowing down the throat and increase the risk of aspiration.

Correct Answer: A

Rationale: The correct answer is A: Neutrophil. Neutrophils are the most numerous type of WBC, typically comprising 50-70% of total WBC count. They are key players in the body's immune response, phagocytizing pathogens. Basophils, eosinophils, and lymphocytes are less numerous than neutrophils. Basophils are involved in allergic reactions, eosinophils combat parasitic infections, and lymphocytes play a critical role in adaptive immunity. However, in terms of sheer numbers, neutrophils outnumber the other types of WBC.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Anemia is a condition where there is a decrease in the concentration of red blood cells. 2. Red blood cells carry oxygen to the body's tissues, so a decrease in their concentration leads to reduced oxygen delivery. 3. This decrease in red blood cell concentration can be measured through a decrease in hematocrit levels. 4. Choices A and B are incorrect because anemia involves a decrease, not an increase, in red blood cells and hemoglobin. 5. Choice D is incorrect as it mentions "decreased blood count cells," which is not a specific term related to anemia. Summary: The correct answer is C because anemia is characterized by a decrease in the concentration of red blood cells, leading to reduced oxygen delivery, while the other choices are incorrect due to inaccuracies in describing anemia.
