The nurse is assessing a child's weight and height during a clinic visit prior to starting school. The nurse plots the child's weight on the growth chart and notes that the child's weight is in the 95th percentile for the child's height. What action should the nurse take?

Correct Answer: A

Rationale: The correct answer is A: Question the type and quantity of foods eaten in a typical day. When a child's weight is in the 95th percentile for their height, it indicates possible overweight or obesity. To address this, the nurse should assess the child's dietary habits to identify any unhealthy eating patterns contributing to excess weight. By questioning the type and quantity of foods eaten, the nurse can provide appropriate guidance on nutrition and healthy eating habits. Summary: B: Encouraging additional snacks may further contribute to weight gain and is not recommended without knowing the current eating habits. C: Recommending a high intake of whole milk may increase calorie intake and potentially worsen the weight concern. D: Assessing for signs of poor nutrition, such as a pale appearance, is important but not directly addressing the weight concern in this scenario.

Correct Answer: C

Rationale: The correct answer is C because it explains that the decision to remove life-sustaining treatments is based on the fact that these treatments are not helping the patient and may actually be causing discomfort. This rationale aligns with the principle of beneficence, which emphasizes doing good and avoiding harm to the patient. It also respects the patient's autonomy by prioritizing their well-being and quality of life. Choice A is incorrect as it focuses on financial reasons rather than the patient's best interest. Choice B is incorrect because it prioritizes hospital resources over individual patient care. Choice D is incorrect as it lacks clarity and may come across as insensitive to the significant other's concerns.

Correct Answer: D

Rationale: The correct answer is D, Living will. A living will is a legal document that outlines a person's preferences for medical treatment if they become unable to communicate their wishes. It specifically addresses life-prolonging procedures. Option A, Do not resuscitate order, is a specific directive to not perform CPR in case of cardiac arrest, not a comprehensive medical care directive. Option B, Healthcare proxy, is a person designated to make medical decisions on behalf of a patient who is unable to do so, not the specific directive itself. Option C, Informed consent, refers to the process of obtaining permission from a patient before conducting a healthcare intervention, not a directive for life-prolonging procedures.

Correct Answer: C

Rationale: The correct answer is C because asking about beliefs about the universe allows the nurse to understand the patient's spiritual needs and provide appropriate support. This action shows respect for the patient's beliefs and can help establish a connection between the patient and the nurse. Referring patients to a specific religious figure (choice A) may not align with the patient's beliefs. Providing prayer booklets (choice B) assumes the patient's belief system and may not be helpful. Avoiding discussing religion (choice D) can hinder the nurse-patient relationship and overlook potential sources of support for the patient.

Correct Answer: C

Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.

Correct Answer: D

Rationale: The correct answer is D: Synergy model of practice. The Synergy model emphasizes matching nurse competencies with patient needs for optimal outcomes. In this scenario, the charge nurse assigned the experienced, certified nurse to a complex patient requiring specialized care (sepsis, renal replacement therapy, ventilation), aligning with the model's principle of matching nurse expertise to patient acuity. Assigning the less experienced nurse to stable patients aligns with the model's focus on optimizing patient outcomes by matching nurse competencies appropriately. A: Crew resource management model focuses on teamwork and communication to enhance safety, not specifically on nurse-patient assignments. B: National Patient Safety Goals are broad guidelines for improving patient safety, not specific to nurse-patient assignments. C: Quality and Safety Education for Nurses (QSEN) model focuses on integrating quality and safety competencies into nursing education, not specifically on nurse-patient assignments.

Correct Answer: A

Rationale: The correct answer is A: Give N-acetylcysteine (Mucomyst). N-acetylcysteine is the antidote for acetaminophen overdose. It helps replenish glutathione, which is depleted by acetaminophen metabolism. This prevents liver damage. Choice B, chelation therapy, is not indicated for acetaminophen overdose. Choice C, oxygen therapy, is not directly related to acetaminophen overdose treatment. Choice D, drinking water, will not address the overdose and may not be safe in high doses. Therefore, the best course of action is to administer N-acetylcysteine to prevent liver damage in acetaminophen overdose.

Correct Answer: A

Rationale: The correct answer is A: Advance directive. An advance directive is a legal document that outlines a person's wishes regarding medical treatment and care at the end of life. It allows individuals to specify their preferences for medical interventions if they become unable to communicate. Summary of other choices: B: Guardianship ad item - This does not specifically pertain to an individual's end-of-life care wishes. C: Healthcare proxy - While similar to an advance directive, a healthcare proxy specifically designates a person to make medical decisions on behalf of the individual, rather than specifying their own wishes. D: Power of attorney - This grants someone the authority to make legal decisions on behalf of the individual, but it does not specifically address end-of-life care preferences.

Correct Answer: B

Rationale: The correct answer is B: Change in sputum characteristics. This is a cue for postoperative pneumonia in a COPD patient because it can indicate an infection in the lungs. Postoperative pneumonia is a common complication in patients with COPD due to impaired lung function and weakened immune system. Other choices are incorrect: A) Bradycardia is not a specific indicator of postoperative pneumonia. C) Hypoventilation and respiratory acidosis can be seen in patients with COPD but are not specific to postoperative pneumonia. D) Pursed-lip breathing is a coping mechanism for patients with COPD and is not directly related to postoperative pneumonia.
