A patient’s status deteriorates and mechanical ventilation i s now required. The pulmonologist wants the patient to receive 10 breaths/min from the ventilaabtirobr.c bomu/tt ewst ants to encourage the patient to breathe spontaneously in between the mechanical breaths at his own tidal volume. This mode of ventilation is referred to by what term?
- A. Assist/control ventilation
- B. Controlled ventilation
- C. Intermittent mandatory ventilation
- D. Positive end-expiratory pressure
Correct Answer: C
Rationale: Rationale:
1. Intermittent Mandatory Ventilation (IMV) allows the patient to breathe spontaneously between the preset mechanical breaths.
2. It provides a set number of breaths per minute while allowing the patient to initiate additional breaths at their own tidal volume.
3. IMV is a partial ventilatory support mode, providing a balance between controlled and spontaneous breathing.
4. Assist/Control Ventilation (A) provides full support with every breath initiated by the patient or the ventilator.
5. Controlled Ventilation (B) does not allow for spontaneous breaths by the patient.
6. Positive End-Expiratory Pressure (D) is a separate mode focusing on maintaining positive pressure at the end of expiration, not providing breaths.

A 53-year-old, 80-kg patient is admitted to the cardiac sur gical intensive care unit after cardiac surgery with the following arterial blood gas (ABG ) levels. What is the nurse’s interpretation of these values? pH 7.4 PaCO 40 mm Hg Bicarbonate 24 mEq/L PaO 95 mm Hg O saturation 97% Respirations 20 breaths per minute
- A. Compensated metabolic acidosis
- B. Metabolic alkalosis
- C. Normal ABG values
- D. Respiratory acidosis
Correct Answer: C
Rationale: The correct interpretation is C: Normal ABG values.
1. pH is within the normal range of 7.35-7.45.
2. PaCO2 is 40 mm Hg, within the normal range of 35-45 mm Hg.
3. Bicarbonate is 24 mEq/L, within the normal range of 22-26 mEq/L.
4. PaO2 is 95 mm Hg, within the normal range of 80-100 mm Hg.
5. Oxygen saturation is 97%, which is normal.
6. Respirations are also within the normal range at 20 breaths per minute.
Overall, all values fall within the normal range, indicating a well-maintained acid-base balance. Other choices are incorrect because there are no abnormalities that would suggest compensated metabolic acidosis, metabolic alkalosis, or respiratory acidosis based on the given ABG values.
As the nurse admits a patient with end-stage kidney disease to the hospital, the patient tells the nurse, 'If my heart or breathing stops, I do not want to be resuscitated.' Which action is best for the nurse to take?
- A. Ask if these wishes have been discussed with the healthcare provider.
- B. Place a Do Not Resuscitate (DNR) notation in the patient’s care plan.
- C. Inform the patient that a notarized advance directive must be included in the record.
- D. Advise the patient to designate a person to make health care decisions.
Correct Answer: A
Rationale: Step 1: Asking if these wishes have been discussed with the healthcare provider is important to ensure that the patient's wishes are documented and considered in the care plan.
Step 2: The healthcare provider needs to be aware of the patient's preferences regarding resuscitation to provide appropriate care.
Step 3: This step helps in clarifying the patient's preferences and ensures that the healthcare team follows the patient's wishes.
Step 4: Placing a DNR notation without consulting the healthcare provider may not align with the patient's overall care plan and may lead to potential legal and ethical issues.
Step 5: Informing the patient about notarized advance directives and designating a person for healthcare decisions are important but not the immediate step needed in this scenario.
In summary, choice A is correct as it prioritizes communication with the healthcare provider to ensure the patient's wishes are properly documented and followed. Choices B, C, and D are incorrect because they do not involve confirming the patient's wishes
The nurse educator is evaluating the care that a new registered nurse (RN) provides to a patient receiving mechanical ventilation. Which action by the new RN indicates the need for more education?
- A. The RN increases the FIO2 to 100% before suctioning.
- B. The RN secures a bite block in place using adhesive tape.
- C. The RN asks for assistance to reposition the endotracheal tube.
- D. The RN positions the patient with the head of the bed at 10 degrees.
Correct Answer: D
Rationale: The correct answer is D because positioning the patient with the head of the bed at 10 degrees is incorrect for a patient receiving mechanical ventilation. The optimal position for such patients is to elevate the head of the bed to 30-45 degrees to prevent aspiration and improve oxygenation. Option A is incorrect as increasing FIO2 before suctioning is appropriate to ensure adequate oxygenation. Option B is incorrect as securing a bite block in place using adhesive tape is a standard practice to prevent the patient from biting on the endotracheal tube. Option C is incorrect as asking for assistance to reposition the endotracheal tube shows the RN is aware of the importance of proper placement to ensure effective ventilation.
Which strategy is important to addressing issues associated with the aging workforce? (Select all that apply.)
- A. Allowing nurses to work flexible shift durations
- B. Encouraging older nurses to transfer to an outpatient se tting that is less stressful
- C. Hiring nurse technicians that are available to assist wit h patient care, such as turning the patient
- D. Developing a staffing model that accurately reflects th e unit’s needs.
Correct Answer: A
Rationale: The correct answer is A: Allowing nurses to work flexible shift durations. This strategy is important in addressing issues associated with the aging workforce because it acknowledges the changing needs and preferences of older nurses. By offering flexible shift durations, older nurses can better manage their work-life balance, reduce physical strain, and continue contributing to the workforce effectively.
Choices B, C, and D are incorrect because they do not directly address the specific needs of the aging workforce. Encouraging older nurses to transfer to a less stressful outpatient setting may not align with their career goals. Hiring nurse technicians to assist with patient care may not address the unique experience and expertise of older nurses. Developing a staffing model, while important, does not specifically cater to the needs of aging nurses in terms of flexibility and support.
As part of the admission process, the nurse asks several questions about family relationships. The nurse bases these actions on which rationale?
- A. Assessing family relationships is an initial step in including the family in patient care.
- B. These questions are part of the admission assessment tool required by this CCU.
- C. The nurse has a natural curiosity and wishes to know how the family members relate for her own knowledge.
- D. There is an ongoing research study to identify variant family patterns related to disease incidence.
Correct Answer: A
Rationale: Step-by-step rationale for why choice A is correct:
1. Involving the family in patient care is crucial for holistic care.
2. Assessing family relationships helps identify support systems and potential conflicts.
3. Understanding family dynamics aids in creating a comprehensive care plan.
4. Family involvement can enhance patient outcomes and satisfaction.
Summary of incorrect choices:
B. Irrelevant, as the focus is on patient-centered care, not just fulfilling an assessment tool.
C. Personal curiosity is not a valid reason for assessing family relationships in healthcare.
D. Conducting research on family patterns does not directly impact the immediate care of the patient.
