A nurse is directed to administer a hypotonic intravenous solution. The nurse expects that compensatory mechanisms associated with hypovolemia would cause all of the following symptoms except:

Correct Answer: C

Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.

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: D

Rationale: The correct answer is D: Active listening. Active listening is crucial when working with a dying client and their family as it involves fully concentrating, understanding, responding, and remembering what is being said. This technique helps the nurse show empathy, build trust, and provide emotional support. By actively listening, the nurse can better understand the client's needs and concerns, which is essential in end-of-life care. Reflection (A) involves paraphrasing what the client said, which may not always be appropriate in this sensitive situation. Clarification (B) and Interpretation (C) involve adding one's own understanding or perspective, which can be intrusive and may not align with the client's feelings or beliefs.

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.

Correct Answer: A

Rationale: The correct answer is A: Client’s wife. She is the primary source of information as she witnessed the event firsthand and provided relevant details. In this scenario, the wife's account of the event is crucial in understanding the sequence of events leading to the client's unconscious condition. Medical documents (B), test results (C), and assessment data (D) are all secondary sources of information that may provide additional data but do not have the same level of immediacy or firsthand knowledge as the client's wife. In an emergency situation, information from a reliable eyewitness is often the most valuable initial source for healthcare providers to make critical decisions.

Correct Answer: A

Rationale: The correct answer is A: To detect rejection. After heart transplantation, heart biopsy is performed to monitor for rejection, a common complication. Tissue samples are examined for signs of rejection, such as inflammation. This is crucial for timely intervention to prevent rejection-related complications. Other choices are incorrect: B: Heart functionality is typically assessed through imaging tests like echocardiograms, not biopsy. C: Heart rate monitoring can be done through non-invasive methods like electrocardiograms, not biopsy. D: Checking for heart tumors is not a primary purpose of heart biopsy post-transplantation.

Correct Answer: B

Rationale: Step 1: The scenario describes Toni minimizing her visual problems, planning advanced degrees, seeking full-time jobs, and wanting more children. Step 2: Choice B is correct because it recognizes Toni's behavior as a coping mechanism to deal with her illness. Step 3: Minimizing visual problems and focusing on future goals can be a way for Toni to maintain a positive outlook and cope with her challenges. Step 4: Choices A, C, and D are incorrect because they do not address Toni's behavior as a coping mechanism. Choice A mentions euphoria, which is not supported by the scenario. Choice C and D do not acknowledge Toni's coping mechanism but instead focus on different aspects like disease process and physical functioning.

Correct Answer: B

Rationale: The correct answer is B because ordinal petition in the family is not a recognized risk factor for developing cancer. Age is a well-known risk factor as cancer incidence increases with age. Race can also influence cancer risk due to genetic and environmental factors. Lifestyle choices such as smoking, diet, and physical activity can significantly impact the likelihood of developing cancer. In contrast, ordinal petition in the family does not have a direct association with cancer risk.

Correct Answer: C

Rationale: The correct answer is C because in Addisonian crisis, the client experiences adrenal insufficiency leading to decreased cortisol levels and impaired stress response. Offering extra blankets and raising room temperature helps prevent hypothermia, as clients in crisis are unable to regulate body temperature. Encouraging independence with ADLs (choice A) and ambulation (choice B) are not priorities as the client is in a critical state. Placing the client in a private room (choice D) is not directly related to managing Addisonian crisis.
