A mother brings her children into the clinic and they are diagnosed with chickenpox. The mother had chickenpox as a child and is not concerned with contracting the disease when caring for her children. what type of immunity does this mother have?

Correct Answer: A

Rationale: The correct answer is A: Active natural immunity. The mother had chickenpox as a child, which triggered her immune system to produce antibodies, providing long-lasting protection. This is an example of active immunity because her immune system actively responded to the pathogen. Summary: B: Passive artificial immunity - This involves receiving pre-made antibodies, not produced by the individual's immune system. C: Passive natural immunity - This is acquired through placental transfer or breastfeeding, not through prior exposure to the pathogen. D: Active artificial immunity - This is acquired through vaccination, not through natural exposure to the pathogen.

Correct Answer: A

Rationale: The correct answer is A: Muscle rigidity and spasms. Ketamine can cause muscle rigidity and spasms as a side effect. The anesthesiologist should monitor the client for this adverse reaction. Muscle rigidity and spasms are common with ketamine administration and can affect the client's comfort and safety during the procedure. It is important for the nurse to promptly address any signs of muscle rigidity or spasms to prevent complications. Summary of why other choices are incorrect: B: Hiccups - Ketamine can cause hiccups, but it is not the primary side effect to monitor for in this scenario. C: Extrapyramidal reactions - Ketamine does not typically cause extrapyramidal reactions. D: Respiratory depression - Ketamine is known for its minimal effect on respiratory depression compared to other anesthetics. Monitoring respiratory depression is still important, but not the primary concern with ketamine administration in this case.

Correct Answer: C

Rationale: The correct answer is C: The patient is apprehensive about discharge. This is the correct answer because the patient's fear of going home and being alone indicates apprehension about discharge, which is a common feeling among patients transitioning from the hospital to home care. This subjective data suggests that the patient may need additional support and education prior to discharge to address their fears and concerns. A: The patient can now perform the dressing changes without help - This is incorrect because the patient's fear of going home and being alone does not necessarily indicate their ability to perform dressing changes independently. B: The patient can begin retaking all of the previous medications - This is incorrect as the fear expressed by the patient is related to being alone at home, not to medication management. D: The patient’s surgery was not successful - This is incorrect as there is no indication in the subjective data provided that the surgery was not successful.

Correct Answer: A

Rationale: The correct answer is A: Trousseau's sign. This involves carpal spasm induced by inflating a blood pressure cuff above systolic pressure, indicating hypocalcemia. The nurse should monitor for this sign in clients at risk for low calcium levels. Hypoglycemia and hypokalemia have specific signs and symptoms not related to Trousseau's sign. Respiratory changes are nonspecific and may not be directly related to monitoring for low calcium levels.

Correct Answer: A

Rationale: The correct answer is A because continuous assessment allows for timely identification of changes in the client's condition. This is crucial for providing appropriate and timely interventions. Assessing the client only at specific times (choices B and C) may lead to missing important changes. Choice D is incorrect because assessments should not be limited to physician rounds; they should be ongoing to ensure comprehensive care.

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: 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: Step-by-step rationale for why choice A is correct: 1. The American Cancer Society recommends yearly mammograms after age 40 for early breast cancer detection. 2. Mammograms are most effective for women aged 40 and older in detecting breast cancer. 3. Regular mammograms can help detect breast cancer at an early stage, improving treatment outcomes. Summary of why other choices are incorrect: B: Mammograms should start at age 40, not after the birth of the first child. C: Mammograms are not recommended after the first menstrual period; they should start at age 40. D: Mammograms should be done annually after age 40, not every 3 years between ages 20 and 40.

Correct Answer: A

Rationale: The correct answer is A because determining whether an intervention is correct and appropriate for the given situation indicates critical thinking in nursing care implementation. This involves assessing the patient's needs, analyzing the situation, and using evidence-based practice to make informed decisions. This process ensures that interventions are tailored to individual patient needs and promotes safe and effective care delivery. Option B is incorrect because performing a procedure without clinical competency can jeopardize patient safety and is not an example of critical thinking. Option C is incorrect as establishing goals without assessment lacks a foundation in data and may lead to inappropriate care planning. Option D is incorrect as evaluating the effectiveness of interventions is a part of the nursing process but does not specifically demonstrate critical thinking in implementation.
