Autoimmunity is defined as a phenomenon involving which of the following?

Correct Answer: D

Rationale: Autoimmunity is when the immune system mistakenly attacks the body's own cells. Choice D is correct because it reflects this key feature - the inability to differentiate self from nonself. This leads to the immune system targeting healthy tissues. Choices A, B, and C are incorrect as they do not accurately describe autoimmunity. Choice A refers to endotoxins destroying B cells, which is not the definition of autoimmunity. Choice B mentions overproduction of reagin antibody, which is not related to autoimmunity. Choice C is incorrect as autoimmunity does not involve depression of the immune response but rather an inappropriate immune response.

Correct Answer: B

Rationale: Step 1: Providing a solution of hydrogen peroxide and water as a mouth rinse helps in reducing the pain of stomatitis by promoting oral hygiene and preventing infections. Step 2: Hydrogen peroxide has antimicrobial properties that can help in reducing bacteria in the mouth, which can worsen stomatitis. Step 3: Rinsing with this solution can also help in cleansing the oral mucosa and reducing inflammation, thereby decreasing pain. Step 4: This intervention directly addresses the nursing diagnosis of impaired oral mucous membrane and is focused on symptom management. Summary: A: Recommending the client to discontinue chemotherapy is not a feasible option as it is essential for treating cancer. C: Monitoring platelet and leukocyte counts is important but does not directly address the pain of stomatitis. D: Checking for signs and symptoms is necessary but does not provide direct relief for the pain of stomatitis.

Correct Answer: D

Rationale: The correct action for the nurse to take first is to obtain a Doppler and recheck the pedal pulses. This is the correct choice because it allows the nurse to further assess the circulation in the lower extremities. By using a Doppler, the nurse can accurately detect the presence or absence of pedal pulses, which is crucial in evaluating the severity of the patient's condition. This step provides objective data that can guide the next course of action. Choice A is incorrect because emergency surgery should not be anticipated without further assessment. Choice B is incorrect as assessing apical and radial pulses is not relevant in this situation. Choice C is incorrect as elevating the foot of the bed and applying warm compress may not address the underlying circulation issue.

Correct Answer: B

Rationale: The correct answer is B: Risk for impaired skin integrity related to edema, skin fragility, and poor wound healing. This nursing diagnosis takes highest priority for a client with hyperparathyroidism because the client is at risk for skin breakdown due to edema, skin fragility, and poor wound healing caused by the condition. Skin integrity is crucial for preventing infection and promoting overall health. Choice A is incorrect because hyperparathyroidism is not related to thyroid hormone excess, but rather to parathyroid hormone excess. Choice C is incorrect because body image disturbance is not the highest priority compared to the risk of skin breakdown. Choice D is incorrect because hyperparathyroidism typically leads to hypercalcemia and not imbalanced nutrition related to thyroid hormone excess.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. The nurse is utilizing assessment data to analyze and interpret the information to develop a nursing diagnosis. This involves critical thinking skills to make conclusions and create a plan of care. A: Assigning clinical cues - This choice is incorrect as it refers to identifying objective and subjective data during assessment, not the process of analyzing and synthesizing data to form a diagnosis. B: Defining characteristics - This choice is incorrect as it typically refers to the specific manifestations or symptoms associated with a particular nursing diagnosis, not the process of diagnosing itself. D: Diagnostic labeling - This choice is incorrect as it refers to the final step in the nursing diagnosis process where the nurse assigns a label to the identified problem, not the overall process of diagnostic reasoning.

Correct Answer: A

Rationale: The presence of redness, swelling, and induration at the wound site are indicative of infection. Redness and swelling suggest inflammation, while induration indicates tissue hardening and can be a sign of infection spreading. Infection can delay healing and lead to complications if not treated promptly. Evisceration refers to wound opening with protrusion of internal organs, not indicated by the symptoms. Dehiscence is the partial or complete separation of wound layers, not represented by the symptoms. Hemorrhage involves excessive bleeding, which is not described in the scenario. Therefore, choice A is correct as it aligns with the signs observed and is the most appropriate response for the situation.

Correct Answer: C

Rationale: The correct answer is C: 15 to 20 g of a fast-acting carbohydrate such as orange juice. In this scenario, the client is experiencing hypoglycemia, which can lead to confusion and abnormal behavior. Administering fast-acting carbohydrates like orange juice will help quickly raise the blood sugar levels. This is the first-line treatment for conscious patients with hypoglycemia. Choice A (I.M. or subcutaneous glucagon) is used for unconscious patients or when oral intake is not possible. Choice B (I.V. bolus of dextrose 50%) is too aggressive for a conscious patient and may lead to complications. Choice D (10 U of fast-acting insulin) would further lower the blood sugar levels and worsen the situation. Administering fast-acting carbohydrates is the safest and most effective approach for conscious patients with hypoglycemia to quickly raise their blood sugar levels and resolve their symptoms.

Correct Answer:

Rationale: Correct Answer: A: The patient will ambulate in the hallway twice this shift using crutches correctly. Rationale: 1. This choice outlines a specific nursing intervention - ambulating with crutches. 2. It includes clear actions for the patient to ambulate and specifies using crutches correctly. 3. It addresses the patient's physical mobility needs actively. 4. It focuses on promoting independence and functional ability. Summary of other choices: B: This choice includes the nursing diagnosis and the plan but lacks the specificity of the correct answer. C: This choice includes the nursing diagnosis and specifies the use of crutches but lacks the clarity of correct implementation. D: This choice only identifies the patient's condition without providing a specific nursing intervention.

Correct Answer: D

Rationale: The correct answer is D: throbbing headache. Nitroglycerin is a vasodilator that relaxes blood vessels, leading to increased blood flow and reduced workload on the heart. One common side effect of nitroglycerin is a throbbing headache due to the dilation of blood vessels in the brain. This side effect is expected and usually diminishes with continued use. Explanation of other choices: A: High blood pressure - Nitroglycerin actually helps lower blood pressure by dilating blood vessels. B: GIT irritation - This is not a common side effect of nitroglycerin, as it primarily affects the cardiovascular system. C: Shortness of breathing - This is not a typical side effect of nitroglycerin, as it does not directly affect respiratory function.
