When assessing the patient for hypoxemia, the nurse recognizes what as an early sign of the effect of hypoxemia on the cardiovascular system?
- A. Heart block
- B. Restlessness
- C. Tachycardia
- D. Tachypnea
Correct Answer: C
Rationale: The correct answer is C: Tachycardia. Hypoxemia results in decreased oxygen levels in the blood, stimulating the body to increase heart rate to improve oxygen delivery. Tachycardia is an early sign of the cardiovascular system compensating for hypoxemia. Heart block (A) is a disruption in the electrical conduction within the heart and is not directly related to hypoxemia. Restlessness (B) is a non-specific sign and can be caused by various factors. Tachypnea (D) is an increased respiratory rate, which is a response to hypoxemia but not a direct effect on the cardiovascular system.

When caring for a patient with a pulmonary artery (PA) pressure catheter, the nurse observes that the PA waveform indicates that the catheter is in the wedged position. Which action should the nurse take next?
- A. Zero balance the transducer.
- B. Activate the fast flush system.
- C. Notify the health care provider.
- D. Deflate and reinflate the PA balloon.
Correct Answer: C
Rationale: The correct answer is C: Notify the health care provider. When the PA waveform indicates the catheter is in the wedged position, it means the catheter tip is in the pulmonary artery, potentially causing complications. The nurse should notify the healthcare provider immediately to assess and reposition the catheter to prevent further issues. Zero balancing the transducer (A) or activating the fast flush system (B) are not appropriate actions for this situation. Deflating and reinflating the PA balloon (D) could exacerbate the issue and should only be done under the guidance of the healthcare provider.
The nurse is caring for a patient who is being evaluated clianbiircba.clolmy/ tfeostr brain death by a primary care provider. Which assessment findings by the nurse sup port brain death?
- A. Absence of a corneal reflex
- B. Unequal, reactive pupils
- C. Withdrawal from painful stimuli
- D. Core temperature of 100.8° F
Correct Answer: A
Rationale: The correct answer is A, absence of a corneal reflex, because in brain death, all brainstem reflexes, including the corneal reflex, are absent. This indicates complete loss of brain function. Choice B, unequal reactive pupils, is incorrect as it suggests some level of brainstem function. Choice C, withdrawal from painful stimuli, is also incorrect as it is a spinal reflex and can occur even in the absence of brain function. Choice D, core temperature of 100.8° F, is irrelevant to assessing brain death.
The spouse of a patient with terminal cancer visits daily and cheerfully talks with the patient about wedding anniversary plans for the next year. When the nurse asks about any concerns, the spouse says, 'I’m busy at work, but otherwise, things are fine.' Which nursing diagnosis is most appropriate?
- A. Ineffective coping related to lack of grieving.
- B. Anxiety related to the complicated grieving process.
- C. Caregiver role strain related to feeling overwhelmed.
- D. Hopelessness related to knowledge deficit about cancer.
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.
The critical care environment is stressful to the patient. Which interventions assist in reducing this stress? (Select all that apply.)
- A. Adjust lighting to promote normal sleep-wake cycles.
- B. Provide clocks, calendars, and personal photos in the p atient’s room.
- C. Talk to the patient about other patients you are caring for on the unit.
- D. Tell the patient the day and time when you are providi ng routine nursing interventions.
Correct Answer: A
Rationale: Correct Answer: A. Adjust lighting to promote normal sleep-wake cycles.
Rationale:
1. Adjusting lighting can help regulate the patient's circadian rhythm, promoting better sleep and reducing stress.
2. Normal sleep-wake cycles are crucial for overall well-being and healing in a critical care setting.
3. Proper lighting can also create a more calming environment for the patient.
Summary of Incorrect Choices:
B. Providing clocks, calendars, and personal photos can be overwhelming for a stressed patient.
C. Talking about other patients may increase anxiety and breach patient confidentiality.
D. Telling the day and time of routine interventions may disrupt the patient's sense of time and add to stress.
Which assessment finding obtained by the nurse when caring for a patient receiving mechanical ventilation indicates the need for suctioning?
- A. The patient’s oxygen saturation is 93%.
- B. The patient was last suctioned 6 hours ago.
- C. The patient’s respiratory rate is 32 breaths/minute.
- D. The patient has occasional audible expiratory wheezes.
Correct Answer: C
Rationale: The correct answer is C because a respiratory rate of 32 breaths/minute indicates increased work of breathing, which could be due to secretions that need to be suctioned. High respiratory rate may suggest inadequate oxygenation and ventilation. Oxygen saturation of 93% (choice A) is within an acceptable range and does not necessarily indicate the need for suctioning. Time since last suctioning (choice B) should be considered but is not as immediate an indication as an increased respiratory rate. Occasional audible expiratory wheezes (choice D) may be indicative of other respiratory issues but do not directly indicate the need for suctioning.
