A patient is having difficulty weaning from mechanical ve ntilation. The nurse assesses the patient and notes what potential cause of this difficult weaning?

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin of 8 g/dL. Low hemoglobin levels can lead to inadequate oxygen delivery to tissues, causing respiratory distress and difficulty weaning from mechanical ventilation. This is due to reduced oxygen-carrying capacity leading to increased work of breathing. A: Cardiac output of 6 L/min is within normal range and not directly related to difficulty weaning from mechanical ventilation. C: Negative sputum culture and sensitivity indicate absence of respiratory infection but not a direct cause of difficulty weaning. D: White blood cell count of 8000 is within normal range and not a direct cause of difficulty weaning.

Correct Answer: A

Rationale: The correct answer is A: Ineffective coping related to lack of grieving. The spouse's behavior of avoiding the reality of the terminal illness and focusing on future plans indicates maladaptive coping. The cheerfulness and denial suggest a lack of acceptance and processing of the impending loss. This can lead to emotional distress and hinder the grieving process. Choice B (Anxiety related to the complicated grieving process) is incorrect because the spouse's behavior does not exhibit signs of anxiety but rather avoidance and denial. Choice C (Caregiver role strain related to feeling overwhelmed) is incorrect as the spouse does not express feeling overwhelmed but instead deflects by focusing on work. Choice D (Hopelessness related to knowledge deficit about cancer) is incorrect because the spouse's behavior does not indicate hopelessness or lack of understanding about cancer, but rather an avoidance of facing the reality of the situation.

Correct Answer: D

Rationale: Correct Answer: D - Give acetaminophen (Tylenol) 650 mg per nasogastric tube. Rationale: LPNs/LVNs are trained to administer medications, including oral and nasogastric routes. Giving acetaminophen via nasogastric tube is within their scope of practice. LPNs/LVNs should have the knowledge and skills to safely administer this medication as part of the hypothermia protocol. Summary of other choices: A: Continuously monitor heart rhythm - This requires specialized training and skills typically within the scope of registered nurses or cardiac monitoring technicians. B: Check neurologic status every 2 hours - Assessing neurologic status requires critical thinking and clinical judgment, which are typically responsibilities of registered nurses. C: Place cooling blankets above and below the patient - Positioning and managing cooling devices may require specific training and should be done under the supervision of a registered nurse.

Correct Answer: B

Rationale: The correct answer is B: Encouraging family members to make notes of questions they have for the physician during family rounds. This strategy helps families cope with the stress of critical illness by empowering them to stay informed and actively participate in the patient's care. By encouraging them to make notes, it promotes effective communication with the healthcare team and ensures that their concerns and questions are addressed promptly. Other choices are incorrect: A: Asking the family to leave during the morning bath to promote the patient’s privacy is not a helpful strategy for coping with stress as it may lead to feelings of isolation and lack of involvement in the patient's care. C: Providing continuity of nursing care is important but may not directly address the family's coping mechanisms during a critical illness. D: Providing a daily update of the patient’s condition to the family spokesperson is valuable but may not fully address the family's need for active participation and communication with the healthcare team.

Correct Answer: B

Rationale: The correct answer is B: Cluster nursing activities so that the patient has uninterrupted rest periods. Rationale: 1. Clustering nursing activities allows for uninterrupted rest periods, essential for improving sleep quality and addressing disturbed sensory perception. 2. Administering sedatives or opioids (Option A) can lead to drug dependence, tolerance, and adverse effects in older adults. 3. Silencing alarms (Option C) compromises patient safety by impeding timely monitoring and response to critical events. 4. Eliminating assessments (Option D) between 0100 and 0600 disregards the necessity of monitoring vital signs and assessing patient condition around the clock.

Correct Answer: C

Rationale: The correct answer is C: Rhinorrhoea or otorrhoea with Halo sign. This finding is consistent with a basilar skull fracture because it indicates a cerebrospinal fluid (CSF) leak from the skull base. The Halo sign refers to a ring of CSF surrounded by blood, which can be seen on a white absorbent pad. This specific sign is a classic indicator of a basilar skull fracture, as the CSF leakage from the ears or nose can be tinged with blood due to the fracture disrupting nearby blood vessels. For the other choices: A: Hematemesis and abdominal distention are not typical manifestations of a basilar skull fracture. They are more indicative of gastrointestinal issues or internal bleeding. B: Asymmetry of the face and eye movements can be seen with facial nerve or orbital injuries, but it is not specific to a basilar skull fracture. D: Abnormal position and movement of the arm are not directly related to a

Correct Answer: D

Rationale: Pulse oximetry measures oxygen saturation in the blood by analyzing the absorption of light by hemoglobin. Oxygen saturation indicates the percentage of hemoglobin molecules carrying oxygen. This is essential for assessing respiratory function and oxygen delivery to tissues. Arterial blood gases (Choice A) directly measure oxygen and carbon dioxide levels in the blood, not specifically oxygen saturation. Hemoglobin values (Choice B) provide information about the amount of hemoglobin present but not its oxygen-carrying capacity. Oxygen consumption (Choice C) is a measure of how much oxygen is used by tissues, not what pulse oximetry directly measures.

Correct Answer: C

Rationale: The correct answer is C because inquiring about specific cultural rituals and preferences shows respect for the patient's cultural beliefs and values. By asking about these aspects, the nurse can provide care that aligns with the patient's cultural background, promoting comfort and understanding. This action also demonstrates a commitment to individualized care. Choice A is incorrect because standardized care may not always be culturally appropriate. Choice B is incorrect as avoiding discussions about death can hinder effective communication and support. Choice D is incorrect as advising families to strictly follow hospital guidelines may overlook the importance of cultural considerations in end-of-life care.

Correct Answer: A

Rationale: The correct answer is A: Alarm stage. The husband's rapid heart rate indicates the initial alarm reaction to stress, characterized by physiological arousal. This stage involves the body's fight-or-flight response to a stressor. In this scenario, the husband is experiencing the physiological effects of the stressful situation, such as the auto accident and loss of a limb. The other choices are incorrect because: B: Exhaustion stage occurs if stress continues without relief, leading to depletion of resources and increased vulnerability to illness. C: Resistance stage is the body's attempt to adapt and cope with the stressor after the initial alarm reaction. D: Adaptation stage is not a recognized stage in the general adaptation syndrome model.
